ICE MAKER

GENERAL INSTRUCTIONS AND

OPERATION

1.The refrigerator must be connected to 120 volts AC before the ice maker can operate. The water valve supplying the refrigerator must be turned on, and the ice level bail arm in the fully down position. See figure 12.

position

2.When the ice maker thermostat senses the preset temperature for the ejection of the ice cubes, the fingers will start to rotate, dumping any ice cubes and filling the mold with water. When the storage container is full, the bail arm will come in contact with the ice cubes. The bail arm cannot return to the full down position and the ice production is stopped until the bin is emptied, or ice cubes are removed.

3.To prevent water from splashing out of the mold assembly when your recreational vehicle is moving, raise the bail arm to the full “UP/OFF” position about 1-1/2 hours before departing. This will allow the water in the mold to freeze.

WATER SUPPLY

The water supply system must have a minimum pres- sure of 15 pounds per square inch gauge (psig). A 1/4” diameter water line to the water valve should be used at the rear of the refrigerator. The water line must have a manual shut off valve placed where it is easily acces- sible.

HOW TO ADJUST SIZE OF CUBES

Note: If the ice maker was cleaned and drained, no ice cubes will be dumped into the bin during the first cycle.

1.The first few cycles may have small cubes due to air trapped in the water lines. The first container of ice cubes should be dumped if the water system has been winterized or not used for several weeks.

2.Once the ice maker has run through several cycles and if cubes are to small or sticking together, adjustment is necessary on the amount of water entering the mold.

3.Remove the protective cover from the ice maker mechanism. See figure 13.

4.Locate the adjusting screw under the protective cover. Turn the screw counterclockwise to increase the size of cubes. Turn the screw clockwise to decrease the cube size or if the mold is overfilling, and the cubes are stuck together.

Important: To prevent overfilling, DO NOT turn the adjustment screw more than one revolution at a time. Allow the ice maker to cycle several times before another adjustment is made. Be sure to replace the protective cover on the cycle after the adjustments are complete.

WINTER OPERATION

1.Your refrigerator is equipped with a heater tape wrapped around the water solenoid valve and outlet water tube. During cold weather operation below 32°F/°C the automatic temperature switch will turn the heater tape on automatically. If the recreational vehicle is in storage and the refrigerator or the DC power is turned “OFF” there will be no 12V DC present to operate the heat tape; therefore, it will be necessary to drain the ice maker.

If the temperatures are expected to reach or exceed 0°F/-18°C the ice maker must be drained to prevent component damage and leaks.

Follow the instructions in Section “ How to Drain the Ice Maker”.

HOW TO DRAIN THE ICE MAKER

Note: Water, compressed air and AC power are required to drain the ice maker. Draining of the ice maker must be done by a qualified service technician.

1.If the RV will not be in use for an extended period of time or put into storage, the ice maker should be drained and dried. This will prevent water from freezing in the solenoid valve or becoming stale and producing bad tasting ice.

2.Shut off water supply valve to the ice maker.

3.Place a shallow pan under water solenoid valve.

4.Remove inlet fitting to ice maker water solenoid valve. Drain water from the supply line.

See figure 14.

5.Remove the plastic nut and water line from outlet side of water solenoid valve. Drain water from the line. See figure 14.
