WATER LEVEL CONTROL

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 13). 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 recom-
mended 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 Adjust-
ment.

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 ice maker and its refrigeration system. Switch will reset as soon as cause of water failure has
been corrected and proper water level in ice maker 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 ice maker assembly itself. (See Cleaning Procedure).
