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. 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 in the Installation Manual.

URPOSE
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.)
