Receiving & Unpackaging
Dispensers
All equipment leaves our distribution points in new condition.
When receiving new equipment, please pay close attention to the packaging for
any damage to the crating. If there appears to be any exterior damage, please
either note the damaged on the delivery bill of lading OR refuse it.
Failure to note damage on BOL or refuse damaged equipment means
that the receiver accepts all liability for damaged equipment.

Installation, Start Up, and Check
Please double check these items before install & start-up before calling for service.
(These items are not covered under your Labor Warranty)
1. Has all tape and packing materials been removed from Machine?
2. Is the unit installed in a location that is away from heat generating equipment or direct sunlight?
3. Is the unit level front to back and side to side? This unit is equipped with legs which are adjustable from 3.25” – 4” in height.
4. Is the correct electrical power provided? Ensure the unit has the specified voltage and amperage and is on adedicated circuit. Do not use a
drop cord or power strip with any ice machine. This could cause a voltage drop and compensatory amperage spike or cause the circuit
breaker to trip.
5. Check drain line pipe sizes. Insure they are ¾ inch and line drops ¼ inch per foot of run to insure both machine and bin drainage is
effective.
6. Is water supplied to the unit? Water Line size, 3/8 inch, must be supplied to ensure sufficient water flow is always available.Required
water pressure is 20 psi minimum and 80 psi maximum. This unit is designed to work with water temperatures of 50°F -90°F.
7. Is the unit installed in an area with sufficient ventilation on top for proper rejection of condenser heat and maintenance? The manufacturer
requires 14” of clearance above the unit for maintenance and service. Never block the top vents on the unit! Fresh air is taken in from the
bottom and dispelled from the top.
8. This unit is designed to work in ambient air temperatures of 50°F -100°F.
9. Scale or Mold build-up can affect the sequence of operation and production. Is a water filter installed? We recommend our exclusive
Citryne Pro Ice Filtration for the best results. Scale will increase operating costs and reduce or shut down the machine’s
performance.
10. Do not install this unit outdoors.

Proper Installation
ID-0300
Ensure the power switch is set to ‘ON’
and the ICE-OFF-WASH switch is
set to ‘ICE’.
Ice will begin to enter the hopper after 3
minutes of the compressor & condenser
fan being energized.
You can begin to use the ice 10 minutes
after that and the hoper will be full
of ice after about 70 minutes.

PCB connections are clearly marked and have LEDs to indicate to the
technician when certain parts are powered.
By separating the main PCB from the FND, Icetro has managed to keep
the cost of a replacement PCB lower than all its competitors!

Maintenance & Leaks
Visually inspect all hex head bolts
holding lower housing assembly
to evaporator barrel for leaks.
Drains have been enlarged to
prevent overflow & scale
buildup on critical parts.
Use caution during reassembly
to ensure new bolts are cross
tightened evenly.
14

Maintenance & Leaks
Poor maintenance, leaking gaskets/bolts, or a plugged drain can destroy a machine: If bolts
at the top extruder or lower housing assembly leak, scale can build up on the urethane
insulation, the lower housing assembly, and/or the gear box and destroy those parts.
When removing bolts, new o-rings and/or new bolts with o-rings should be used.
If bolts are not tightened properly (or o-rings damaged) the leaks above will occur.
Should the drain pan’s drain line
become plugged, it will overflow and
cause scale to greatly damage unit.

Detailed Operation
Sequence
Item Contents
Initial power-up.
ICE-OFF-WASH switch is in
The ‘Ice’ position.
1. Water inlet solenoid energized for 20 seconds for initial water reservoir fill.
2. Dump solenoid energizedfor 30 seconds & then water inlet solenoidenergized for
10 seconds. (This occurs 3 consecutive times)
3. Gear motor is energized.
4. After 60 seconds of the gear motor being energized, the compressor & condenser
fan motor are both energized.
5. Ice begins to enter the ice hopper after 3 minutes of the compressor being
energized.
Ice Hopper Full
1. When bin switch opens for 2 consecutive seconds, the machine is recognized as
being full and the compressor & condenser fan motor are de-energized.
2. Gear motor continues to run for 60 seconds & is then de-energized.
Ice Hopper Low
1. When bin switch closes for 2 consecutive seconds, the machine returns to the ice
making mode and the gear motor is energized.
2. After 60 seconds of the gear motor being energized, the compressor & condenser
fan motor are both energized.
Water Inlet Solenoid
1. Energized when low level/high level float switch is in the NC (down)position.
2. De-energized when high level float is in the NO (up) position.
3. Triggers error code (Er15) when the high-level float is not detected after operating
for 60 seconds.
Gear Motor
1. Energized when the high-level float is detected.
2. Stops after a 60 second delay when bin switch opens.
3.
After 1 hour of no operation, gear motor will energize for a 12 second agitation. This
will continue everyhouruntil the bin switch closes and normal operationresumes.
Compressor 1. Energized 60 seconds after the gear motoris energized.
2. Stops immediately when the bin switch opens, indicatingthe ice hopper is full.
18

Item Contents
Dump Solenoid 1. Energized for 2 seconds after 1 hour of machine operation.
2. This is repeated indefinitelyuntilthe power is turned off.
Dispense Lever Operation
1. Chose a dispensing option (ice, water, or ice + water) and place cup against lever to
engage it.
2. If dispensinglever is released and immediately engaged again, there will be a 2
second delay before any solenoids will activate, regardless of which mode is
selected.
3. Once the dispensing lever is disengaged, all operation stops immediately.
Ice DispensingSolenoid
(Ice Mode)
1. Energized when the dispensingleveris engaged, and the N/O switch is closed.
2. De-energized when the dispensing lever is released, and switch opens again.
3. Maximum operatingtime is 20 seconds by default but can be changed.
4. If ice hopper is full, the gear motor will also energize to dispense ice.
Ice & Water DispensingSolenoid
(Ice + Water Mode)
1. Ice & water solenoids are both energized simultaneously when the dispensinglever
is engaged, and the N/O switch is closed.
2. Maximum operatingtime of the ice solenoid is 5 seconds by default but can be
changed.
3. Maximum operatingtime of the water solenoid is 3 seconds by default but can be
changed.
4. If ice hopper is full, the gear motor will also energize to dispense ice.

Water Dispense Solenoid
(Water Mode)
1. Energized when dispensingleveris engaged.
2. Stops when dispensing lever is disengaged.
3. Maximum operatingtime is 5 seconds.
Time Counter
1. Gear Motor utilizes a counter to track the number of hours in active operation.
2. At 10,000 hours, the LED of the current selected mode will blink for 5 seconds & will
continue the initial mode selection.
3. At 11,0000 hours, the LEDs of all mode buttons will blink for 5 seconds each hour.
4. To reset the counter, place dip switch 2 in the ‘ON’ position and press the reset
button on the main PCB.
5. When dip switch 2 is ‘ON’ the LEDs on all mode buttons will blink from left to right,
and noneof the dispenserfunctions will work,until dip switch 2 is placed back in the
‘OFF’ position.
ICE → OFF 1. Compressor stops immediately.
2. Gear motor stop after a 60 second delay.
OFF → WASH
1. Gear motor is energized for 5 minutes.
2. Dump solenoid is energized for 1 minute.
3. Water solenoid is energized until the high-level float sensor opens.
4. Gear motor is energized for 1 minute.
5. Dump solenoid is energized for 30 seconds.
6. Steps 3-5 are executed 2 more times and the machine stops.
