Power Requirements

The merchandiser is supplied with a service cord for the country of use and is terminated in a grounding type plug. The wall receptacle used for this merchandiser must be properly polarized, grounded, and of the correct voltage. Operating the merchandiser from a source of low voltage will VOID YOUR WARRANTY. Each merchandiser should have its own electrical circuit and that circuit should be protected with a circuit breaker or fuse conforming to local regulations.

Voltage Check - Place the leads of a voltmeter across the LINE (LIVE) and NEUTRAL terminals of the wall receptacle. The voltmeter should indicate 110-130 volts ac for 120 volt,

60 Hz locations, or 220- 240 volts ac for 230 volt, 50 Hz locations.

Polarity Check - Place the leads of a voltmeter across the LINE (LIVE) and GROUND terminals of the wall receptacle. The voltmeter should indicate 110-130 volts ac for 120 volt,

60 Hz locations, or 220- 240 volts ac for 230 volt, 50 Hz locations.

Noise Potential Check - Place the test leads of a voltmeter across the NEUTRAL and GROUND terminals of the wall receptacle. The meter should indicate 0 volts ac. A measurement greater than 1.5- 2.0 volts ac could result in problems for the merchandiser’s electronic circuitry caused by electrical noise.

Any deviation from these requirements could result in unreliable performance from your merchandiser.

Unpack the Machine

Remove all packing materials from the interior of the machine. Keep all documents; warranty cards, etc. Set aside the base plate kit (if present).

Controls and Indicators

Interlock Switch. When the cabinet door is open, this switch turns off the glass heater, optional fan (if so equipped) and turns on the service light (not present on all models).

Low Voltage Switch. Informs the controller software of the main door open or closed status.

Message Display. This is how the merchandiser communicates with the outside world. Customers can see messages about how much money they have put into the merchandiser. The message display also tells customers when a selection is sold out and when vending is free, inhibited, or discounted. The message display shows you what you are doing when you program the merchandiser, and can show you what is wrong if there is a failure.

Free Vend Keyswitch (optional). This allows someone (other than maintenance people) to set the merchandiser to free vend without opening the door.

Selection Switch Panel. The customer uses these switches to make selections. Also, maintenance people may use this switch panel during programming and other support modes.

Coin Return Button. Pressing this button returns any coins that have been paid into the merchandiser prior to a vend.

Bill Acceptor (Optional). Accepts bills in various denominations, depending upon the type of bill validator, and how the machine is configured.

Service Keypad. The service keypad is located at the top of the monetary panel. It gives service personnel the means to program, retrieve data from, and view diagnostic information about, the merchandiser.

Main Controller PCB Display. This display consists of two light emitting diodes (LED) mounted on the controller PCB.

POWER ON (L.E.D. 1). When lit, this red LED indicates electrical power is applied to the controller PCB.

HEARTBEAT (L.E.D. 2). When flashing, this red LED indicates that the controller PCB is active, and the software is operating.

NORMAL CONDITIONS: When the merchandiser is operating normally, you should see a steady red POWERindicator and a flashing red HEARTBEAT indicator. Contact a service representative if any other condition exists.

Back Side of U.S./Canada Power Panel. The circuit board mounted on the rear of the power panel is a dc power supply for the coin mechanism. A fuse protects the board circuitry in the event of a coin mechanism solenoid failure. If the coin mechanism is not working, check this fuse. If the fuse is blown, a bad coin mechanism solenoid could be at fault.

How to Turn the Merchandiser ON and OFF

Power to the merchandiser is controlled by the main power switch, located on the power panel. The power panel is on the right side of the merchandiser, behind the monetary door. There is a main power switch and a main circuit breaker located in a row on the power panel.

WARNING

Lethal voltages are present. Unplug the merchandiser whenever you do one of the following tasks:

Change a fuse
Change the fluorescent lamp
Change the lamp starter
Connect or disconnect a harness (except a motor harness when the tray has been removed) Failure to do so may result in personal injury.

Initial Set-Up

1. Move the Merchandiser Through a Narrow Doorway

Note: If necessary, this merchandiser can be moved through an opening as narrow as 30 inches by removing panels at the top and bottom of the cabinet.

REMOVE THE TOP PANEL:

1. Remove the two screws that secure each end of the panel to the cabinet.

2. Pull the panel forward to remove it from the merchandiser.

REMOVE THE BOTTOM PANEL:

1. Remove the screws that secure the panel to the cabinet.
2. Pull the panel forward to remove it from the cabinet.

TAKE THE MERCHANDISER THROUGH THE OPENING:
1. Open the cabinet door and place it square with the left side of the cabinet.
2. Carefully walk the merchandiser through the opening.

REASSEMBLE THE MERCHANDISER
1. Replace the upper and lower panels.

2. Position the Merchandiser

Move the merchandiser to its approximate position. (There are some procedures you need to do before it is in its permanent location.) Plug in your merchandiser and turn the power switch to ON. You can position this merchandiser anywhere in a bank of machines. It can even be placed on an end flush against a side wall.

The 167 and 168 merchandisers should be located at least one inch away from the back wall.
The 764, 765, 784, 785, 786, 787, 788, 789, 797, and 798 merchandisers should be placed at least six inches away from the back wall. This will provide adequate air circulation for the refrigeration unit.
The 764, 765, 787, 788, 789, 797, and 798 merchandisers will operate more efficiently when placed in a shaded location.
There should be enough room in front of the merchandiser for the door to move freely.
WARNING

This machine is only rated for installation in an indoor location.

TIME OUT !!!

Now that you have placed your machine near its permanent location, you need to set up some of the special options you may have.

IF YOUR MACHINE HAS A COFFEE SECTION . . . Grab the booklet entitled ”HOTDRINK MODULE SETUP AND OPERATOR’S GUIDE” and follow the setup procedures contained in it. After you have done that, come right back here and proceed with the next step.

NOW, IF YOUR MACHINE IS EQUIPPED WITH A CAN, COLD FOOD,

OR FROZEN FOOD MODULE . . . Grab the booklet entitled ”CAN, COLD FOOD AND FROZEN FOOD MODULE SETUP AND OPERATOR’S GUIDE” and follow the setup procedures contained in it. After you have done that, come right back here and proceed with the next step.

Now continue with the snack set up.

Snack Section Set-Up

1. Place A Tray In The Loading Position

2. Place both hands on the tray.

3. Lightly push back on the tray with your palms. This will release the tray latches on the sides of the tray.

4. Push down on the tray latches with your thumbs.

5. Pull the tray toward you until you hear and feel the rear tray rollers drop into a cut-out in the top of the guide rail.

6. Continue pulling the tray forward for another inch. You will then be able to tilt the tray downward into the loading position.

7. Lightly lift the front of the tray and pull the tray toward you until you hear and feel the tray rollers drop into the cut-out in the top of the guide rail.

8. Continue Pulling the tray forward for another inch. You will be able to tilt the tray downward into the loading position.

NOTE

When the cabinet door is not fully open, the bottom tray will rest on the delivery pan assembly. Handle the tray with care to avoid scratching the delivery pan assembly.

1. Set Up Trays to Vend Products

These instructions will guide you through setting up your trays for vending. You will be asked to determine if your tray can physically hold the products you intend to vend. If not, you will be directed to other procedures which will help you get them set up. Follow these nine steps for each tray in your machine:

1. Make sure the tray is in the loading position.

2. Is the column wide enough for the intended product? If so, proceed to the next step. Otherwise, set up your tray to vend wider products. When you’re done, return to step 3 in this procedure.

3. Will the products fit between the spiral turns? If so, proceed to the next step. Otherwise, change the spiral.

4. Will the product pass under the tray immediately above? If so, proceed to the next step. Otherwise, reposition the tray and guides.

5. Will the product touch products on either side? If not, proceed to the next step. Otherwise, install a product spacer.

6. Load products in the tray.

7. Return the tray to the vending position.

8. Install the price rolls.

9. Install the selection ID numbers
2. Set Up A Tray To Vend Wide Products

The following steps will help you configure your tray to vend wide products. When you have completed the procedures called out in each step, return to the next step in the procedure. When you are done with the entire wide product steps, return to the set-up procedures above.

1. Remove the tray from the merchandiser and place on a flat surface.

2. Based on the size of the product you want to vend, decide how many spiral positions it will occupy. Please remember that the leftmost spiral in the group must have an even ID number (0, 2, 4, etc.) For example, if a product is three spirals wide, the left spiral will be ID number 0, and the right spiral will be ID number 2. Be careful how wide you set up for, because really wide products could get hung up in the delivery door.

3. Remove the column dividers inside the group. In the example of three spiral positions, you would be removing the dividers between spiral ID numbers 0 and 1, and 1 and 2.

4. If your group only consists of 2 spirals, replace the rightmost motor with a spiral bearing and gear, and install a gear on the leftmost motor. Skip to step 8.

5. Remove all spirals in the group except the leftmost spiral.

6. Do one of the following:

a. If your group has an ODD number of spirals (3, 5, etc.) remove the harnesses from all motors in the group except the leftmost one. To the rightmost motor, connect the harness from the motor immediately to its left.

b. If your group has an EVEN number of spirals (4,6, etc.) remove the harnesses from all motors inside the group (leave the harnesses connected to the leftmost and rightmost motors).

7. Install a spiral at the rightmost position in your group. Make sure it has the same product capacity and is opposite to the one in the leftmost position.

8. Return the tray to the merchandiser.

9. Electronically couple the motors as needed (see your Programming Guide for information).

10. Return to step 3 in the Set Up Trays to Vend Products procedure, above.

3. Removing a Tray

Study this procedure before you install a tray for the first time; while you are holding the tray you will not be able to see this area. Proceed as follows:

1. Push back on the tray slightly with your palms. This releases the tray latches.

2. Push down on the tray latches with your thumbs.

3. Pull the tray forward until you hear and feel the rear tray rollers drop into a cut-out in the top of the guide rail.

4. Lightly lift the front of the tray and pull the tray toward you until you hear and feel the rear tray rollers drop into a cut-out in the top of the guide rail.

5. Unplug the tray wiring harness from the PC board mounted on the tray guide rail JUST ABOVE the tray you are removing.

6. Lift up on the tray and slide it toward the back. No more than an inch should be needed.

7. The tab near the back of the tray should align with the cut-out in the top of the guide rail.

8. Lift the tray clear of the guide rail and out of the merchandiser.

CAUTION

When the cabinet door is not fully open, use extra care in removing the bottom tray. Failure to do so may result in damage to the tray or to the delivery pan assembly.

4. Removing And Installing Column Dividers

1. Push the column divider toward the back of the tray .

2. Lift the column divider clear of the tray.

3. Install the column divider in the reverse order of removal.

5. Operate a Tray Outside the Machine

6. Return the tray to the merchandiser. See INSTALLING A TRAY IN THE MERCHANDISER.

2. Installing a Gear

WHEN ARE GEARS USED?

Gears are used to mechanically couple the spirals together.

This happens whenever you have two spirals and only one motor for vending a selection.

WHERE ARE THE GEARS PLACED?

The gear is placed between the back of the tray and the spiral coupler.

HOW IS THE GEAR ORIENTED?

There are two possible orientations for the gear:

1. Gear sets against back wall of the tray.
2. Gear is set away from back wall.

There are two rules to follow when orienting gears:

RULE 1 - The gears for selections next to each other cannot use the same orientation.

RULE 2 - All gears for a single selection must use the same orientation.

3. Installing a Spiral Coupler

1. Place the gear in position if one is required for this set-up. (See INSTALLING A GEAR).

2. WHEN USED WITH A MOTOR: Hold the motor in place and push the spiral coupler through the motor gear box until it clicks into position.

RIGHT SPIRAL COUPLER IS ONE POSITION CLOCKWISE FROM VERTICAL TO THE RIGHT AS VIEWED FROM THE FRONT.

3. WHEN USED WITH A COUPLER BEARING: Hold the coupler bearing in place and push the spiral coupler through the bearing until the coupler clicks into position.

4. Moving a Tray Up or Down

This merchandiser can be adjusted to vend taller products. Some guidelines must be followed:

Keep in mind that when you increase the product height available to a tray by lowering it, you will be decreasing the product height available to the tray below.

If a tray is in the lowest position, the tray below it should not be in the highest position.

If a tray is in the highest position, the tray above it should not be in the lowest position.

You will need to experiment with various tray positions to get the best results for your products.

CAUTION

The trays in a model 764, 765, 787, 788, or 789 merchandiser should not be positioned over an open air discharge vent.

NOTE

Tray movement is limited because the tray harness will limit the amount of travel available to the tray guide rails.

Proceed as follows:

1. Remove the tray from the merchandiser. See REMOVING A TRAY.

2. Remove the screw that secures the right tray guide rail to the front guide mounting channel.

3. Tap up on the guide rail and unseat the guide rail tabs from the channel slots.

4. Pull the guide rail away from the front and rear guide mounting channels.

5. Move the guide rail to the desired position.

6. Insert the guide rail tabs into the mounting CV channel slots.

7. Tap down on the guide rail to seat the tabs in the channel slots.

8. Replace the screw that secures the guide rail to the front guide mounting channel.

9. Repeat steps 2 through 8 for the left guide rail.

10. Return the tray to the merchandiser. (See INSTALLING A TRAY IN THE MERCHANDISER).

11. Load products into the trays, and perform test vends. Make sure the trays don’t interfere with the products you are vending, and that all products vend properly.

5. Installing a Tray in the Merchandiser

Study this procedure before you install a tray for the first time; while you are holding the tray you will not be able to see this area. Proceed as follows:

1. Insert the tray so that the tray rollers pass over the tray guide rollers.

2. Bring the tray roller to rest on the tray guide.

3. Tilt the tray upward.

4. Connect the tray wiring harness to the PC board mounted to the guide rail JUST ABOVE the tray you are installing.

5. Hold the tray up while pushing it toward the rear. Stop when the tab on the tray aligns with the opening in the tray guide.

6. Lower the tray until it rests on the tray guide roller. Push the tray in all the way.

7. The tray latch will fall into the locking position.

10. Installing and Removing a Product Spacer

INSTALLING A PRODUCT SPACER:

Insert the product spacer mounting pins into the column divider.

ADJUSTING A PRODUCT SPACER:

With product loaded in the tray, rotate the product spacer up or down to keep the product upright.

REMOVING A PRODUCT SPACER:

Pull the product spacer mounting pins from the column divider.

1. Load Trays With Product

SPIRAL CAPACITY COLOR CODES

SPIRAL CAPACITY	SPIRAL COUPLER COLOR
6	PURPLE
11	BLUE
13	YELLOW
15	RED
20	WHITE
25	GREEN
30	BLACK
38	ORANGE

The color of the spiral coupler (the little plastic tab attached to the rear of the spiral will tell you how many products will fit in the spiral.

NOTE

Another way to determine spiral capacity is to count the spaces in the spiral!

LOADING A TRAY WITH PRODUCTS IN GENERAL:

See PRODUCT PUSHER USAGE for spirals with capacity of 11,13, or 15.

See SPIRAL WALL RETAINER USAGE for spirals with capacity of 20, 25, 30, or 38.

Begin loading products at the front of the tray and work toward the back. Position the product so the package rests on the tray. DO NOT force a product into a spiral.

If the fit is too tight or too loose, change the spiral size. (See REMOVING AND INSTALLING A SPIRAL).

Be sure there are no empty positions between products in each spiral.

SPECIAL CONSIDERATIONS:

Bagged Products - Position package upright, then push the tops slightly toward the rear of the tray. Also, see PRODUCT PUSHER USAGE.

Thin Packages - Position the package upright. Also, see SPIRAL WALL RETAINER USAGE.

KitKat - The two right-most columns of the candy tray are designed to accept the KitKat candy bar.

Chilled Candy - Use the lowest trays for candy that is to be chilled.

WARNING

This merchandiser does not have a health control circuit. It is not approved for the vending of perishable food items.

SPIRAL WALL RETAINER USAGE:

A spiral wall retainer serves to compress the spiral and make it act like a spring to more forcefully eject a product. Do some test vends and use a spiral wall retainer when a product does not readily leave the spiral.

Use a spiral wall retainer in the following cases:

The spiral has a capacity of 20, 25, 30, or 38.

The product is thin.

The product is on a candy tray.

The spiral wall retainer can also be used with other spirals and types of products.

The spiral wall retainer is installed near the front of the column divider.

There are two ways to install the spiral wall retainer.

1. To install a spiral wall retainer, insert the retainer in the square slot near the front of the column divider.

2. The spiral wall retainer must be removed in two cases:

A Kit-Kat bar loaded into either of the two right hand positions of a tray will not clear the retainer on the column divider between the two positions.

A product pusher will catch on a retainer in Orientation A.

PRODUCT PUSHER USAGE:

The product pusher will give the top of a product an extra tilt to help it fall into the delivery pan.

Use a product pusher in the following cases:

The spiral has a capacity of 15, 13, or 11.

The package is non-rigid like bagged peanuts.

The product pusher can also be used with other spiral and types of products.

A bag of product pushers has been shipped with the merchandiser. Additional product pushers are available from the National Vendors’ parts department. To use a product pusher, snap it on the spiral. You can adjust the product pusher by moving it around on the spiral to achieve the best vending results.

PREPARING THE MERCHANDISER FOR VENDING ”LUNCH BUCKET”:

Because of the weight and shape of the package, National Vendors recommends that this product be vended only from the bottom tray.

To vend this product, two adjacent positions must be coupled together.

( See INSTALLING A GEAR, for mechanical coupling directions, or see the Programming Guide for electrical coupling directions).

The left spiral coupler should be installed one position counterclockwise from the vertical position.

The right spiral coupler should be installed one position clockwise from the vertical position.

Replace the current spirals with six-count spirals. These are available from the National Vendors parts department. (See REMOVING AND INSTALLING SPIRALS). A pad can be installed in the bottom of the delivery pan to quiet and cushion product delivery. This part is available from the National Vendors parts department.

PREPARING THE MERCHANDISER FOR VENDING ”TOP SHELF”:

National Vendors recommends that this product be vended from a candy tray.

Move the tray so the package can be loaded standing on its left or right edge. (See MOVING A TRAY UP OR DOWN.)

The following steps must be completed for three adjacent positions on the tray:

The remaining steps to prepare the Merchandiser for this product are intricately associated with illustrations. Rather than attempt a translation, the reader/listener is directed to the original Crane National Guide. (Note: None of the steps will be used in testing).

1. Return the Trays to the Vending Position

1. Lift the tray until it is parallel to the floor.

2. Push the tray toward the back of the cabinet. The tray latches on the sides of the tray will lock into position.

2. Install and Set Price Labels

Price rolls are printed on coiled-up strips. (The dollar and cents rolls are factory installed.) If you use another type of currency, you will find the appropriate price rolls in the plastic bag that contained this manual.

There are two types of price rolls installed:

Dollar roll - 1 to 12, increments of 1

Cents roll - 00 to 95, increments of 05

Remove the price rolls as required, and install the appropriate one(s) for your currency.

INSTALLING PRICE LABELS:

There are three pairs of slots in the front of the can unit for each position. Install per this example:

1. Insert the dollar roll in the left-most pair of slots if the price is $1.00 or more.

2. Insert the cents roll in the center pair of slots.

3. The low-number end of the roll goes in the top slot and the high-number end of the roll goes in the bottom slot.

ADJUSTING THE PRICE ROLL:

You can set selection prices within the following range:

Minimum price $ .00 Maximum price $12.95 Increment $ .05

1. Use your thumb to move each price roll up or down as needed to set the desired price.

NOTE

You will see the word STOP near either end of the roll.

3. Install Selection ID Labels

Selection ID numbers are printed on clear plastic sheets. You will find these in the plastic bag that contained this manual. You will need to separate them along the scored lines between the selections. BE CAREFUL when doing this, because it is easy to split the labels.

INSTALLING SELECTION ID NUMBERS:

1. Install Price Labels

The column ID labels have already been attached to the delivery door, and a set of self-adhesive price labels are in the plastic bag that contained this manual.

Stick the desired price label next to the column ID number

2. Put the Gum and Mint Dispenser in the Loading Position

The gum and mint assembly is hinged to the delivery pan assembly and is held in the vending position by two magnets. The gum and mint assembly is held in the loading position by a hook and a loop. One end of the hook is attached to the right side of the door. The loop is mounted on the right side of the gum and mint assembly.

Use the loop as a handle and raise the gum and mint magazine with your left hand. With your right hand, move the free end of the hook so it catches the loop. This will hold the magazine while you are loading it with product.

3. Load the Gum and Mint Dispenser With Product

1. The gum and mint assembly lid is held closed by two magnets. Open the lid toward the inside of the merchandiser door.

Keep your hand on the product pusher until it comes to rest behind the last item in the column. Failure to do so may result in personal injury or in damage to the dispenser.

4. Return the Gum and Mint Dispenser in the Vending Position

1. Make sure all product pushers are in the vending position.

2. Close the gum and mint assembly lid.

3. Hold the loop on the right side of the magazine with your left hand. Release the hook with your right hand and lower the magazine.

4. Continue to hold the loop until the magazine has been fully lowered.

5. Pivot the gum and mint assembly back to the vending position.

5. REMOVING AND INSTALLING COLUMN REDUCER

The two left-most vending columns from the loading side can be adjusted for two different widths.

When a column reducer is in place, the width of the column will be 3 1/16 inches.

When a column reducer is removed, the width of the column will be 3 7/8 inches.

TO REMOVE A COLUMN REDUCER:

1. Pull the reducer away from the cabinet door to disengage the locking tabs.

2. Lift up to remove the reducer from the gum and mint assembly.

TO INSTALL A COLUMN REDUCER

1. Place the reducer on the gum and mint dispenser so the locking tabs are in the slots.

2. Push the reducer toward the cabinet door to lock the reducer in place.

Final Installation

Move the merchandiser to its final position:

You can position this merchandiser anywhere in a bank of machines. It can even be placed on an end flush against a side wall.

The 167 and 168 merchandisers should be located at least one inch away from the back wall.

The 764, 765, 784, 785, 786, 787, 788, 789, 797, and 798 merchandisers should be placed at least six inches away from the back wall. This will provide adequate air circulation for the refrigeration unit.

The 764, 765, 787, 788, 789, 797, and 798 merchandisers will operate more efficiently when placed in a shaded location.

There should be enough room in front of the merchandiser for the door to move freely.

WARNING

This machine is only rated for installation in an indoor location.

1. Level the Merchandiser

1. Place a spirit level on the top front edge of the cabinet with the door fully closed. Adjust the front legs only until the cabinet is reasonably level.

2. Hold the door open about 4 inches. (This relieves any stress the door may be placing on the cabinet.)

WARNING

Have an assistant hold the merchandiser while you adjust the leg levelers.

3. Adjust the back legs so that the back leg leveler on the hinge side is off the floor just enough so a piece of paper can slide under it with only a bit of resistance.

4. For proper weight distribution on all four legs, raise the back leg on the hinge side by unscrewing the leveler 1 1/2 turns.

5. You may need to use pliers or channel locks to loosen the leg levelers.

NOTE

A slight slope from front to back will improve the draining of condensate from merchandisers with refrigerating units. When the merchandiser is part of a bank of machines, level it in reference to the other machines. After leveling is complete, check that the door operates easily.

Refrigeration Modules

Complete the setup of chilled snack features (models 764, 475, 787, 788, and 789):

1. Connect a Refrigeration Module to an External Drain (optional)

METHOD 1:

1. Remove the condensate drain tube from the refrigeration module.

2. Connect a new drain tube to the refrigeration module housing.

3. Route the new tube to an external drain or to an overflow bucket.

METHOD 2:

1. Connect a drain tube to the condensate pan.

2. Route the drain tube to an external drain or to an overflow bucket.

2. Adjust the Air Discharge and Return Vents (Chiller Only)

The air discharge and return vents are located in the right front and rear side wall. The vents are adjusted by loosening the screw and sliding the air duct shutter up or down as required. With the shutter all the way up, the vent is fully open. The vent is closed when the shutter is all the way down. Ideally, the temperature at the top tray should be the same as that at the bottom tray. Using a thermometer to monitor temperature, adjust the air discharge and return vents until the temperatures are as close together as possible.

CAUTION

Do not close off all discharge vents. Doing so can damage the refrigeration unit.

1. Install the Base Plate

WARNING

Do not move the cabinet while the hex head screws and/or carriage bolts are loosened. The cabinet would become unstable and likely to tip and cause injury.

1. Remove the waste pail and the grounds pail from the merchandiser (refreshment center only).

2. Remove the floor liner from the merchandiser (refreshment center only).

3. Remove the two caps.

4. Loosen the left leg assembly carriage bolts and nuts to allow mounting a base plate bracket.

5. Secure one of the base plate brackets to the leg assembly using the two carriage bolts. Tighten the carriage bolts and nuts.

6. Loosen the right leg assembly hex screws to allow mounting the other base plate bracket.

7. Secure the other base plate bracket to the right leg assembly using the two hex head screws. Tighten the hex head screws.

8. Insert the short arms of the slides into the hinged tabs of the base plate. Position the slide so the notch near the short arm is on the bottom side.

9. Insert the long arms of the slides into the base plate brackets.

10. Insert and secure a cotter pin through the hole in the back of each of the slides.

11. Push the base plate toward the merchandiser cabinet. The front tabs of the base plate brackets should seat in the notches in the long arms of the slides.

12. Replace the caps, liner, and pail(s) removed previously.

2. Install the Lock Cylinder

Install an optional lock cylinder in the merchandiser as follows: 1. Position the lift handle lock lever.

2. Depress the lock spring at the square hole of the lock cylinder receptacle and pull the lock springs out through the front.

3. Position the lock cylinder. Depress the spring loaded lock pin.

4. Push the cylinder into the cylinder receptacle in the lever. The pin should snap into the square hole.

5. If the cylinder pin does not seat in the square hole, press against both ends of the lock cylinder. Rotate the cylinder until the pin snaps into place.

6. Leaving the door open, test the lock mechanism with a key.

3. Install the Optional Cash Box Lock

1. Remove the cash box from the merchandiser.

2. Assemble the lock as follows: First put in the lock cylinder through the front panel. Then put washer, nut, lock bar, and then the screw.

3. Return the cash box to the merchandiser.

1. Set up the Coin Mechanism

If the changer is not a MARS TRC 6000, proceed to LOADING THE COIN MECHANISM.

If the changer is a MARS TRC 6000, you must set the high quarter switch.

Programming

The Service Keypad

The service keypad is your major tool to program your merchandiser. If you just need to get your merchandiser up and running, you only have to set prices. That procedure is given below. For a thorough explanation of how to do all the custom programming features available to you, consult your Programming Guide. It will tell you how to:
