WATER LEVEL CONTROL
HOW WATER LEVEL CONTROL WORKS
When water is introduced through the inlet fitting the float rises. the float pushes against a lever which in turn forces
the poppet assembly against the inlet fitting valve seat which seals the water off. See Figure 3 Before the water inlet is
sealed the safety switch is operated. In the event of a water failure the float would drop down and operate the safety
switch to shut off the machine.
If water level control will not shut off and seal at level
recommended factory operating range.
Under ordinary circumstances adjustment should not be necessar
installed or relocated. If, however, the control becomes inoperative, repair or replace. See Start-Up Adjustment, page
13.

PURPOSE
1. To automatically maintain proper water level in the evaporator when unit is running and making ice.
2. A safety switch is operated in the event of an interruption in water supply. The switch shuts off the electrical
power to the icemaker and its refrigeration system. Switch will reset as soon as cause of water failure has
been corrected and proper water level in icemaker has again been reached.
3. The transparent bowl not only provides a visible check of water level, but also is a good guide to the internal conditions which exist within the icemaker assembly itself. (See Cleaning Procedure.)
TO REPLACE WATER LEVEL CONTROL
Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.

REFRIGERATION SYSTEM ADJUSTMENTS
A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjustments
are made. The refrigeration technician must use high and low side pressure readings, water and air temperatures,
plus general conditions of cleanliness to assess the refrigeration system status when making any adjustments.
All icemaker products are tested and adjusted at the factory prior to shipment where the ambient temperature
anges from 65° to 90°F, depending on the season of the year.

EXPANSION VALVE
You will find a thermostatic expansion valve on icemakers, which is used to control the amount of refrigerant flowing
through the evaporator. Improperly installed or defective expansion valves may cause low production, soft ice,
squeaking from evaporator and excessive load inside evaporator.
By using general refrigeration system troubleshooting along with the pressure charts you can easily determine
ether or not the expansion valve is working properly.

CAUTION:

ADJUSTMENT AND TROUBLESHOOTING
When troubleshooting the expansion valve you must first be sure you have adequate water flowing into evaporator,
a clean condenser, unit is properly ventilated, and system is properly charged and free from any restrictions. Also
be sure compressor is operating properly.
Second, take reservoir water temperature and air temperature from condenser inlet and determine at what
ressure unit should be running. Machines are equipped with thermostatic valves, there is NO adjustment. If
p
correct pressure cannot be obtained, first be sure system has time to stabilize 10–15 minutes. Second, be sure
sensing bulb is located at 12:00 position on outlet side of evaporator about 3–4 inches away from evaporator and
be sure to insulate well and clamp tightly to tubing. If system pressures are still not adequate, take a second water
and air temperature reading and go over other parts of system for possible problems. If proper charge is
questionable evacuate and recharge to nameplate and leak check. If valve still malfunctions replace valve.
When replacing valve be sure to bleed refrigerant gas from low side port so as not to lose refrigerant oil. Use
eneral refrigerant system practices when replacing and recharging unit. After new valve is in place, go through
g
previous monitored adjustments and troubleshooting to be sure valve is functioning properly.
NOTE:Units with thermostatic expansion valve—valve is located on bottom refrigerant line. Sensing bulb
is located on top refrigerant line. On water cooled units adjust condenser modulating valve before
troubleshooting expansion valve.
Very High discharge pressure is presen t in system. Quick disconnects on you gauges will minimize danger and loss
of refrigerant. Comply with federal regulations for reclaiming refrigerant.
CONDENSER MODULATING VALVE
The reason for using a water modulating valve is to supply the correct amount of water to the condenser. and to
maintain a proper operating pressure to refrigeration system high side.
The flow of water through the valve is increased as the high
pressure lowers.
To calibrate the amount of water flow with the refrigeration system high side pressure, turn adjustment screw
cated on end of valve opposite of bellows. Turn screw counterclockwise to raise opening point or clockwise to
lo
lower opening point. Opening point of valve should be set to maintain proper operating pressure in refrigeration
system high side. Refer to Pressure Chart on. Closing point of valve should be set low enough to close valve during
compressor stand–by periods.
NOTE:Cold water will absorb heat faster than warm water. The water flow will therefore automatically
increase as inlet temperature increases.
side pressure rises and is decreased as high side

CONDENSER MODULATING VALVE REMOVAL
Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
1. Disconnect power to unit, then shut off water supply to condenser and evacuate refrigerant from system.
2. Remove inlet water line from Condenser Modulating Valve. Also remove tube from high side refrigerant
line.
3. Remove Condenser Modulating Valve and bracket from unit.
4. Remove valve from bracket.
5. Replace Condenser Modulating Valve by reversing Steps 2 thru 4. Then pull system into vacuum.
6. Charge unit with proper amount of refrigeration.
7. Turn power and water on to unit.
8. With unit running, adjust modulating valve to proper setting.
9. Go through a complete system check.
BIN CONTROL
The type of bin control used on all UC Models is thermostatically controlled. The switch itself is inside the electrical
box of the Dispenser and can be serviced from the front of the unit. The cap tube bulb is located in the thermostat
well directly under the ice inlet.
To test switch, disconnect power to unit and remove one wire from switch. Connect both leads of your ohmmeter to
the Bin Control Switch terminals. With control bulb at room temperature ohmmeter should read “Closed Circuit”.
Now cover the control bulb with ice, within 1 minute switch should “click” and ohmmeter should read “Open Circuit.”
The Bin control is in electrical series with a 24 volt transformer located in the ice dispenser and a 24 volt control
relay located in the Icemaker.
The Bin 24 volt control relay is in electrical series with coil on antifreeze relay along with the low water safety. If unit
is water cooled, the condenser high pressure cut out is also in series.
The Control Switch is held in place inside electrical box by 2 screws. Control bulb is positioned under ice chute
and can be replaced by removing the capillary from the thermostat well.
The most important thing to remember when replacing probe is to be careful not to cut or kink probe and be
sure sensor bulb is located in a position to shut unit down before ice reaches ice chute.
This icemaker is equipped with a safety ice level sensor. This sensor control is located on top of the evaporator.
This switch is also in electrical series with the anti-freeze relay and other safety circuitry.

GEARMOTOR
The gearmotor is equipped with a start relay and a manual reset overload.
When current is applied, the relay energizes and completes t
predetermined speed and the relay drops out, disconnecting the start winding. The run winding remains in the circuit
as long as current is applied.
The purpose of the overload is to automatically shut off the motor in the event of a mechanical bind of the
ransmission, an overload condition within the evaporator or an electrical malfunction. It does this by sensing
t
amperage draw. If the motor stalls the start relay would energize and stay energized. The amperage would surge 5 to
6 times greater than the normal draw. In this event the overload would shut off the transmission in 4 to 8 seconds.
If the motor is subjected to an abnormal load, but does not reach
greater period of time. The reaction time depends upon the amperage to which it is subjected.
