INSTALLATION 

Consult local, state and federal codes and regulations before installation of the vending machine.  To minimize installation time and to avoid service problems due to improper installation, follow the instructions outlined in this manual. 

Position the vending machine in its place of operation no further than six feet (6 ft) from the power outlet or receptacle and check that the door will open fully without interference. Leave at least four inches of space between the back of the machine and any wall or obstruction for proper air circulation. 

Level the vending machine, making sure all levelers are touching the floor. The vending machine must be level for proper operation. If it is properly leveled, it should not "rock" or "teeter" on any of the levelers. When the vending machine is level, the door can be opened to any position and not move by itself. Try the door half closed, straight out and in a wide open position before deciding that the machine is level. 

Remove all shipping brackets, tape and inner packing material from the vending machine. Operating the vending machine without removing the tape and packing material could result in damage to the vending machine. 

1. Grounding (Earthing) & Electrical

Refer to the Safety Manual and Installation Guidelines (P/N 4206816) that shipped in the service package with your machine. 

Prior to connecting the equipment, the integrity of the main electrical supply must be checked for correct polarity, presence of ground (earth) and correct voltage. It is recommended that these checks be repeated at 6-month intervals with the routine safety electrical testing of the equipment itself. 

To correct negative voltage, amperage, polarities, or ground (earth) checks, consult a licensed electrician. 

For proper operation of any equipment utilizing electronically controlled components, the equipment should be placed on an isolated or dedicated noise free circuit, properly polarized and grounded. Refer to the Electrical Specifications on this sheet to determine circuit amperage and protection.

Set prices for selections H1 through H6 in the same manner you would set prices for existing selections. Refer to the host vending machine for instructions on programming prices. 

10. Load Products

1.   Products featured in front door Live Display must match the product being loaded. 

2.   Funnel slides must be kept clean. Refer to Figure 9 for part names, locations, and product orientation. 

3.   Product container bottoms must face towards the center of the rack as shown. Refer to Figure 10. 

4.   Do not store bottles in "spare" space of the cabinet. The refrigeration unit could be damaged. 

5.   A loading chart has been provided on the inner door to make it easier to keep track of what types of products have been loaded into the SATELLITE VENDING MACHINE. Use a dry erase marker to avoid making a permanent mark. 

6.   If refilling with the same product size into the same column, then load products into the columns. Skip steps 7 through 11. 

7.   If loading for the first time, changing a column to a different product size, or to reset product cradle (motor) to correct position, then load one row of products in each column and test vend each column using real money. 

8.   Add five (5) rows of products in each column to check product spacing. Products should have not more than ¼ to ½ inches of free space at the front or back of the columns as shown on Figure 10 on page 1. Adjust the back spacer, latch striker or gate assembly to achieve the required dimension. The Vend Rack has been factory set for most 20-oz. bottles or 12-oz. cans. If vending 16.9-oz. water bottles remove Filler (4211816) from the back of the inner door and install it in the Vend Rack. Follow instructions on Filler decal. 

9.   If product spacing is correct, then test vend each column using real money. Load the columns to full capacity. 

To adjust the back spacer: 

Lift the back spacer and reposition it in the adjustment slots. Use notch markers as reference points to align it vertically. See Figure 10 on page 1. 

To adjust the latch striker and gate assembly:

DROP SENSOR 

A drop (vibration) sensor on the delivery chute is your assurance that a product has been vended after a selection is made. 

The drop sensor is factory calibrated and should not need adjustment. The sensor indicator light (located on the sensor board below the adjustment screw) will blink when a product hits the delivery chute. See Figure 12. If the light does not blink on impact, then an adjustment should be made. 

Figure 12. Drop Sensor Adjustment & Thermostat

Drop Sensor Adjustment

1.      Locate the sensor adjustment screw on the Drop Sensor Board. See Figure 12. 

2.      Use a small flat head screwdriver to slowly turn the adjustment screw clockwise (increase sensitivity) and stop when the indicator light comes on. 

3.      Slowly turn the adjustment screw counterclockwise (decrease sensitivity) and stop when the indicator light goes out. Continue to turn the adjustment screw counterclockwise three (3) additional turns. Test the sensor for proper operation by tapping the delivery chute. The indicator light should blink when the chute is tapped. 

4.      Close the door and perform several test vends. 

5.      If vending special products, the drop sensor may need the following additional adjustments: 

§      If machine is sending more than one product per vend request, open the door and turn the adjustment screw clockwise ¼ turn to increase sensitivity. 

§       If machine fails to vend product upon vend request, turn adjustment screw counterclockwise ¼ turn (to decrease sensitivity). 

VEND CYCLE 

When a can/bottle selection is made at the host vending machine, then 24VDC is sent from the host controller to the SATELLITE VENDING MACHINE vend motor. The vend motor rotates the product cradle and lets the product drop off the cradle. As the can or bottle drops onto the product delivery chute, the impact or vibration allows the drop sensor to send a low voltage signal to the drop sensor board indicating that a product has been vended. The drop sensor board relays the information to the host control board. After receiving the drop sensor signal, the host control board will recognize how the machine is programmed and responds accordingly. Refer to host vending machine service manual for controller and programming information. 

Sold-Out

Some host vending machines will require resetting. Refer to host vending machine service manual for additional information.  

REFRIGERATION UNIT 

Refrigeration Controls

The thermostat that controls the temperature has been preset at the factory. It is located on the right side under the hopper. See Figure 12 on page 2. If setting up for the first time, please allow sufficient time for the refrigeration system to cool the products. 

Refrigeration Troubleshooting

Know and understand how to service the unit and how it operates. Units may vary, but the operation is basically the same. Never guess at the problem; find the symptom before attempting any repair. 

The sealed hermetic system was not meant to be worked on outside the Factory Service Center. The three things that can go wrong with a sealed system and should be repaired at the Factory Service Center are: 

1.      Low Charge - usually caused by leaks; look for oil around seals and welds. Unit will not cool properly. The capillary tube will be frosted before it enters the evaporator inlet tube. 

2.      Restriction in Systems (unit frost, then melts) - not cooling properly. 

Bad valves - unit does not cool properly; noisy compressor.
