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 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 9.

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.

630460154 12

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.

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_ to 90_F, depending on the season of the year.

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

13 630460154

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 whether or not the expansion valve is working properly.

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 pressure unit should be running. Machines are equipped with thermostatic valves, there is NO adjustment. If 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 general refrigerant 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: Units with thermostatic expansion valve—The 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.

CAUTION: Very high discharge pressure is present in system. Quick disconnects on your 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 side pressure rises and is decreased 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 6. Turn screw counterclockwise to raise opening point or clockwise to 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 page 3. 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.

CONDENSER MODULATING VALVE REMOVAL

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 theevaporator.

This switch is also in electrical series with the anti-freeze relay and other safety circuitry.

15 630460154

GEARMOTOR

The gearmotor 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 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 a 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.
