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 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.
Do not
block the ventilating screens in front or in the rear of the vending machine.
Always allow free ventilation behind a bank installation, so that exhaust air
is not trapped. Failure to do so could result in a refrigeration failure.
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.

LOADING
INSTRUCTIONS
|
|
|
|
To
load products, lift the tray slightly and pull forward until the tray stops
and tilts down. All trays tilt down for easier loading.
Load
products from front to back, making sure all items fit freely between the
augers (also called helixes). See Figure 5.1.
When finished loading each tray, make sure the tray is
returned to its proper position. All trays must be pushed to the rear of the
cabinet and properly seated in the "detent" position.
Place special care products in
tray 6 (bottom tray) so that they are closer to the delivery box, and orient
the products so that they fall bottom first.
Product ejectors
can be added to the end of the augers to help move the product out of the
tray area. See Figure 5.2.

FOR FROZEN FOOD
SATELLITE VENDING MACHINE ONLY
Make sure
that the clear plastic shield is correctly positioned in front of tray 6
after loading the trays. The plastic shield is installed on tray 5 to prevent
the possibility of falling vended products from trays 1 through 4 from
bouncing off the delivery door and into tray 6.
|
|
|
Do not
attempt to force over-size items or packages into the spaces. Do not skip a
space.
|
|
|
|
|
|
Each
auger can be rotated in 20-degree increments, changing the auger position for
a different "drop-off" point at the front of the tray.
For
dual-drive augers, the ideal timing is for the auger ends to meet at the
center of the tray (left auger at 3 o'clock, right auger at 9 o'clock).
Should
you have trouble in vending odd-sized or odd-shaped items, auger re-timing
can be accomplished on a trial and error basis as follows:
1. Disconnect power before servicing.
2. Pull the tray containing the
auger to be re-timed forward to its stop.
3. Remove products from the tray.
4. Push down on motor retaining tab
to release motor from tray.
5. Tilt motor back and lift up
approximately 1/2" to disengage the auger hub from the retaining rib in the
bottom of the tray. See Figure 5.3.
6. Separate the hub from the motor
by pulling forward on the hub to disengage its spline from the motor's
internal gear.
7. Rotate the hub and re-install by
pushing the spline into the internal gear motor.
8. Replace the motor back to its
original position on the rear of the tray while making sure that hub is
correctly installed behind the hub retaining rib.
9. Push motor retaining tab into
slotted hole
10. Load product and push tray into its
vend position (locked onto its detent).
11. Re-connect power and test vend
for proper operation.

Tray Spacing
|
|
The
trays can be raised or lowered in 1/2-inch (12.7 mm) increments to provide
additional headroom for vending taller items.
|
|
|
When
increasing the space between two trays, a corresponding decrease in space of
an adjoining tray will result.
|
|
|
|
To
change spacing, follow the steps outlined below:
1. Disengage the tray harness from
the harness retaining clamp on the right side wall.
2. Disconnect the tray plug from
its receptacle on the right side wall.
3. Lift up on the front of the tray
and pull slightly forward (approximately 1/2-inch/13 mm) to clear the tray
stop.
4. Pull the tray forward until it
stops. Lift up on the rear of the tray and remove it from the machine.
5. Disengage both left and right
tray rails from their corresponding slots on the left and right side walls;
pull inward on the bottom front of each rail and pull its flange out of the
slot.
6. Pull each rail forward to
disengage its rear tab from the hole in the rear wall. See Figure 5.4.
7. Relocate both left and right
walls by reversing steps 5 and 6.
8. Replace the tray by placing its
rear rollers on the left and right rails and lifting up on the front of the
tray as you push it back.
9. Install the tray harness plug
into its receptacle on the right side wall.
10. Push the tray harness into its
harness clamp.
11.
Test vend the tray in its new position to assure that the tray
harness plug is properly connected.
|

The HEALTH
SAFETY feature prevents the sale of perishable food if the air
temperature inside the Satellite Food Vending Machine compartment rises above
the health safety temperature limits (shown in Table
6 on page 2) for more than 15 minutes. The factory defaults for
health safety level and range are automatically set when the default configuration is set, but the
health safety range must match the product selection range of the perishable
products being vended. See Default
Configurations on page 2.
|
|
|
The time
requirements for FROZEN or SLACK levels do not apply for a period of 75 minutes immediately following machine filling
(door open state), servicing (service mode button pressed or door open
detected), or a defrost cycle. The time requirements for the COLD setting do
not apply for 30 minutes immediately following machine filling or servicing.
|
|
|
The
operator is responsible for setting the health safety at the correct level
and selection range for the product being vended.
|
|
|
|
1. Disable Door Switch
|
If machine is
connected to a Satellite Controller, then place removable tape over the door switch (to
simulate closed door) at least 75 minutes before performing the test (step
3). The door switch is located on the bottom right front corner of the
machine.
If the machine
is connected to a snack machine, then open the host vending machine door. While host
vending machine is still in Sales
Mode,
|
|
remove
controller cover. Locate door switch harness connected to terminal P8
(located on top right corner of the controller). Unplug door switch harness
from the controller (to simulate closed door).
2.
Simulate Warm Temperature
Open the door of the Satellite Food Vending Machine.
Locate SENSOR1 on the back of the cabinet above the top tray. Remove
the sensor and save mounting screws. Place the sensor in a cup of warm water
and close door.
3.
Perform Test
Press 0
on the host keypad to check the temperature of SENSOR1. SENSOR1
is displayed on the right side of the display. Wait for SENSOR1 to get above
health safety cut-out temperature: Frozen 0°F, Slacken 15°F, Cold 41°F. Wait
15 minutes and then vend a product from the cold/frozen food vending machine.
If health safety feature (H/S) is functioning properly it
will lock out vending in preset range and instruct customer to make alternate
selection. If this test was started following a defrost or entering service
mode it will take 75 minutes to go out on health safety (H/S).
4.
After Test is Completed
Reinstall the sensor to its original place using the
mounting screws saved from step 2.
If machine is
connected to a Satellite Controller, then remove the tape over the door switch.
If machine is
connected to a snack machine, then reconnect the door switch harness to terminal P8
of the controller.
|
|
|
|
The TEMPERATURE MODE is used to set
the operating parameters of the sensors and the refrigeration unit.
To set the display temperature to Celsius or
Fahrenheit, refer to instructions in Table 8.

If
the refrigeration unit is turned off or the power is interrupted, the
refrigeration unit will start after three (3) minutes provided SENSOR1
probe reading is greater than SENSOR1 SET POINT and ½ of SENSOR1
DELTA.
When
the DEFROST PERIOD (SENSOR2) is reached the compressor and
evaporator fans are turned off and the heater is turned on. DEFROST PERIOD
is unaffected by compressor cycling.
If
either the DEFROST DURATION or the temperature value of SENSOR2
reaches SET POINT, the heater will turn off and the compressor
will turn on. If the temperature value of SENSOR2 is above 30°F,
then the evaporator fans will remain off. If the temperature value of SENSOR2
equals 30°F (-1.1°C) or below, then the evaporator fans turns on and
they will remain on until the refrigeration time period has expired or the
door is opened (door switch contacts closed).
|
|
|
|
When
the service door is opened (door switch contacts
closed) the compressor and evaporator fans are turned off. When the service
door is closed (door switch contacts open) the compressor will turn on only
if off time is greater than three (3) minutes. The evaporator fans will turn
on if the temperature of SENSOR2 is 30°F or below.
If the service
door remains open (door switch contacts closed) for 30 minutes or more, then
the controller will treat it as if the door is now closed and turn on the
compressor and fans as according to the settings. An error message DOOR OPEN ERROR
is set by the controller. This message is cleared when the door is closed
(door switch contacts open). HEALTH SAFETY is reset to the
standard after filling timing upon a door closure.

|
|
Defrost Cycle
Figure 6.1. Defrost Cycle
|
|
|
|
DURATION is the length of time of the defrost cycle. The compressor is off
and the heater turns on to melt ice buildup. It can be adjusted in one (1)
minute increments with a range of 10 to 60 minutes. Default setting is 10
minutes.
PERIOD
is the time from the start of one defrost cycle to the start of the next
defrost cycle, adjustable in half-hour increments (0.5) from 0 to 24 hours.
Default setting is 12 hours.
DELAY is
used to delay the start time of the first defrost cycle. DELAY default is
0 hours and is adjustable in half-hour (.05) increments from 0 to 24
hours. After the first defrost cycle the PERIOD time will control the
defrost cycle. If low humidity conditions, defrost cycle every 24 hours is
recommended.
Example:
·
The current time is 5:00 o'clock
pm. Humidity is low so the machine will probably not get much frost. You
decide that each defrost cycle should last 30 minutes. Duration=30.
·
You decide to start the first
defrost cycle at 2:00 o'clock am tomorrow morning. Since 2:00 am is 9
hours from 5 pm, then delay=9.
·
And every 24 hours from the first
defrost cycle and deciding that approximately 2:00 o'clock am is when few
people will be using the machine. Period=24.
MANUAL if turned on will start a defrost cycle.
The length of time is determined by the DURATION setting. This will not
effect affect the normal defrost period and the next defrost should occur as
normal except if it is less than seventy-five (75) minutes after the manual
cycle. If it is, then it is skipped for the period only.

A
sight glass (located on the rear of the Frozen Food Model 3182) is used for
viewing the condition of the liquid refrigerant. See Figure
6.2. In the center of the sight glass is a moisture
indicator. The plastic cover is used to keep the sight glass free from dust,
dirt and grease.
¨ Bubbles indicate shortage of
refrigerant or a restriction in the liquid line.
¨ The moisture indicator within
the sight glass is a porous filter paper impregnated with a chemical salt
that changes color according to the moisture content (relative saturation) in
the refrigerant. It is formulated so that it
changes color at the moisture levels generally accepted as the safe operating
range.
·
A dark green color indicates the refrigerant is DRY.
·
A chartreuse color indicates caution.
A yellow color
indicates a WET condition.

Know
and understand how to service the unit and how it operates. Units may vary,
but the basic operation is the same. Never guess at the problem; find the
symptom before attempting any repair.
|
|
|
Most
refrigeration problems are electrical.
|
|
|
Breaking the refrigerant joints or seals on this system
voids the unit warranty.
Failure to keep the condenser coil clean and free of
debris voids the unit warranty.
|
|
|
|
The
sealed hermetic system should not 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:
·
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.
·
Restriction in Systems (unit frosts, then melts) - not cooling properly.
·
Bad valves - unit does not cool properly;
noisy compressor.

BEFORE
CALLING FOR SERVICE
|
|
|
|
Please
check the following:
·
Does your machine have at least 4" of clear air space behind it?
·
If the power is turned on at the fuse box, is the machine the only
thing that doesn't work?
·
Is the vending machine plugged directly into the outlet?
Extension cords cause problems.
DO NOT USE EXTENSION CORDS.
·
Is the evaporator coil free of dust and dirt?
·
Is the condenser coil free of dust and dirt?
·
Is the compressor free of dust? (A blanket of dust can prevent the
compressor from cooling off between workouts).
·
Is the circuit breaker at the fuse box reset?
·
Are evaporator fans running? Fold a sheet of 8 1/2" x 11" paper in
half from top to bottom so it is now 8 1/2" x 5 1/2". Place the paper in
front of the evaporator coil and see if the evaporator fans will blow the
paper away.
·
Is the condenser fan running? Fold a sheet of 8 1/2" x 11" paper in
half. Place the paper in front of the condenser coils and see if it draws the
paper to it.
·
Is the shelf in front of the evaporator coil clear? (No tools or
other air-restricting items placed on the shelf).
