Semi–Annually
1.Check for water leaks in tube connections, water fittings and lower Icemaker water seal.
2.Check drain tubes for clogs and aged tubes. Replace if tubes are stained or brittle.
3.Check for signs of condensation. Clean where necessary and replace insulation properly.
4.Check safety circuits for proper operation.
5.Check refrigeration system (see page 13).
6.Check unit for abnormal noise. Tighten machine and cabinet screws, if necessary.
7.Check white upper bearings on auger assembly. If bearings are less than 1/16 thick, replace. See Figure 4

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 rec- ommended 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
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.
