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 4). 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 as indicated, be sure inlet pressure does not exceed rec­ommended factory operating range.

Under ordinary circumstances adjustment should not be necessary providing it was properly adjusted when unit
was installed or relocated. If, however, the control becomes inoperative, repair or replace. See Start-Up Adjust­ment, page 7 .

PURPOSE OF WATER LEVEL CONTROL

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

1. Shut off the water supply . Shut off the main power switch or unplug the ice dispenser from electrical outlet.

2. Remove the flexible tubing from bottom of water level control and drain water from water level control and
evaporator.

3. Remove flexible tubing at bottom of water level bowl connected to the overflow.

4. Hold water inlet fitting with proper tool to prevent it from rotating when disconnecting the water inlet.

5. Remove wing nut holding water control to its mounting bracket. Control can be removed by lifting straight
up.

TO REPLACE WATER LEVEL SAFETY SWITCH

1. Shut off main power switch or unplug the ice dispenser from electrical outlet.

2. Unplug molex connector connecting switch to electrical box.

3. Remove the 2 screws anchoring the water level safety switch to the bottom of the water level control
mounting bracket.

ICE LEVEL CONTROL

The ice level control assembly is secured to the top of the ice storage container cover. The cover is secured to
the storage container with four screws. The level control switch is operated by a plate assembly located beneath
the diaphragm. When the plate assembly is down due to lack of ice in storage container, electrical impulse is
sent to compressor, starting the ice making cycle. As ice level increases in storage container, the plate assembly
is pushed up. When storage container is full, it de--actuates the switch, stopping the compressor and ice making
cycle.

11

638085277

The operating positions of the switch are fixed, no adjustments are necessary. If switch replacement becomes
necessary , simply disconnect cable at connector, remove wires from switch.

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
ranges from 65_F to 90_F, depending on the season of the year.

Whenever a new icemaker is initially installed and started--up, it is imperative that the start --up operator make
the following checks and readjustments for local conditions.

EXPANSION VALVE

You will find a thermal expansion valve on ice makers, 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 trouble shooting along with the pressure charts, you can easily determine whether
or not the expansion valve is working properly.

ADJUSTMENT AND TROUBLESHOOTING

When troubleshooting the expansion valve, you must;

1. Be sure you have adequate water flowing into the evaporator, a clean and properly ventilated condenser,
and the system is properly charged and free of any restrictions. Also be sure compressor is operating prop­erly .

2. Take reservoir water temperature and air temperature from condenser inlet and determine at what pressure
unit should be running. On machines equipped with thermostatic valve there is NO adjustment. If correct
pressure cannot be obtained, be sure system has time to stabilize, 10--15 minutes.

3. Be sure sensing bulb is located at 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 the system for possible problems. If proper
charge is questionable evacuate and recharge to nameplate and leak check. If valve still malfunctions re­place valve.

638085277

12

Use general refrigeration system practices when replacing and recharging unit. After new valve is in place, go
through previous monitored adjustments and troubleshooting to be sure valve is functioning properly .

NOTE: On water cooled units adjust condenser modulating valve before troubleshooting expansion
valve.

CAUTION: Very high discharge pressure is present in system. Quick disconnects on your
gages will minimize Danger and loss of refrigerant. Comply with federal regulations for
reclaiming refrigerant.

CONDENSER MODULATING VAL VE

The reason for using a water modulating valve is to supply the correct amount of water to the condenser to
maintain the proper operating pressure in the refrigeration system high side. The flow of water through the valve
is increased as the high side pressure rises and decreases as high side pressure lowers.

To calibrate the amount of water flow with the refrigeration system high side pressure, turn adjustment screw
located on end of valve opposite of bellows See Figure 4. Turn screw counterclockwise to raise opening point.
Opening point of valve should be set to maintain proper operating pressure in refrigeration system high side.
Refer to Pressure Chart on Page 11. Closing point of valve should be set low enough to close valve during com­pressor stand by periods.

NOTE: Cold water will absorb more heat faster than warm water. The water flow will therefore

automatically increase as inlet temperature increases.

CONDENSER MODULATING VAL VE REMOVAL

1. Disconnect power to unit, then shut off water supply to condenser and reclaim refrigerant from system.

2. Remove inlet water line from Condenser modulating Valve. Also remove tube from refrigerant high side line.

3. Remove Condenser Modulating Valve and bracket.

4. Remove valve from bracket.

5. Replace Condenser Modulating Valve by reversing Steps 2 thru 4. Then pull system into vacuum.

FIGURE 6. ADJUSTMENT SCREW

13

638085277

6. Recharge unit with refrigerant per nameplate.

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.

GEAR MOTOR

The gear motor is equipped with a start relay and a manual reset overload. When current is applied, the relay
energizes and completes the circuit to the start winding. The motor reaches a 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 trans­mission, an overload condition within the evaporator or an electrical malfunction. It does this by sensing amper­age draw. If the motor stalls the start relay would energize and stay energized. The amperage would surge to 5
to 6 times greater than 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 stall condition, the overload will react, but over
a greater period of time. The reaction time depends upon the amperage to which it is subjected.

The overload, through the safety circuit, also shuts off the compressor.
Refer to Troubleshooting Guide.

TROUBLESHOOTING COMPRESSOR

Basically the compressor problems can be narrowed down to three areas of checkout--

1. THE COMPRESSOR WILL NOT RUN

No voltage to the compressor terminals -- check circuit.
Low voltage -- below 90% of nameplate rated voltage.
Problems in the compressor electrical circuit. See Electrical Checkout instructions.

2. THE COMPRESSOR STARTS BUT TRIPS REPEATEDLY ON THE OVERLOAD PROTECTOR

Check for proper fan operation and clean condenser.
Check the compressor suction and discharge pressures.
Voltage -- The voltage should be within 10% of the rated nameplate voltage.
High compressor amperage draw, it should never exceed 120% of the rated nameplate amperage. See

Electrical Checkout Instructions.

3. THE COMPRESSOR RUNS BUT WILL NOT REFRIGERATE

Check the compressor suction and discharge pressures. See Chart on Page 12.

ELECTRICAL CHECKOUT

1. Be sure the unit is disconnected from the power source. Remove the compressor electrical box cover.
Check for obvious damage and loose wires.

2. Disconnect the fan motor leads. Since capacitors store energy, short the capacitor with a screwdriver. This
will prevent shocks.

3. Disconnect the compressor terminal wires.
