ATER

EVEL

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 FIG-

URE 4). 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.

URPOSE OF

ATER

To automatically maintain proper water level in the evaporator when unit is running and making ice.

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.

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).

ONTROL

The ice level control assembly is secured to the top of the ice storage container cover. The cover is

secured to the storage container with four screws. The level control switch is operated by a plate assem-

bly located beneath the diaphragm. When the plate assembly is down due to lack of ice in storage con-

tainer, electrical impulse is sent to compressor, starting the ice making cycle. As ice level increases in

storage container, the plate assembly is pushed up. When storage container is full, it de-actuates the

switch, stopping the compressor and ice making cycle.
