WATER LEVEL CONTROL

W L C
ATER EVEL ONTROL
When water is introduced through the inlet fitting, the float rises (see Figure 1). The float pushes against a lever that in
turn, forces the poppet assembly against the inlet fitting valve seat that 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 Unit.
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, the water level control adjustment should not be necessary providing the control was
properly adjusted when the Unit was installed or relocated (see "Water Level Control Adjustment " in "INSTALLATION
INSTRUCTIONS" SECTION of this manual). If however, the water level control becomes inoperative, repair or replace
the control.

URPOSE OF ATER
1. To automatically maintain the proper water level in the evaporator when the Unit is operating and making ice.
2. A safety switch is operated in the event of an interruption in the water supply. The switch shuts off the electrical
power to the Ice Maker and it's refrigeration system. The switch will reset as soon as the cause of the water fail-
ure has been corrected and the proper water level in the Ice Maker has again been reached.
3. The transparent bowl not only provides a visible check of the water level, but also is a good guide to the internal
conditions which exist within the Ice Maker assembly itself (see cleaning procedure).
