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 that in turn, forces the poppet assembly against the inlet fitting valve seat that seals the water off. See Figure 1 (page 7). 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
PURPOSE OF WATER LEVEL CONTROL
1.To automatically maintain proper water level in the evaporator when the 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.)
TO REPLACE WATER LEVEL CONTROL
1.Shut off the water supply. Shut off the main power switch or unplug the ice dispenser from electrical outlet.
2.Remove the flexible tubing from bottom of water level control and drain water from water level control and evaporator.
3.Remove flexible tubing at bottom of water level bowl connected to the overflow.
4.Hold water inlet fitting with proper tool to prevent it from rotating when disconnecting the water inlet.
5.Remove wing nut holding water control to its mounting bracket. Control can be removed by lifting straight up.
TO REPLACE WATER LEVEL SAFETY SWITCH
1.Shut off main power switch or unplug the ice dispenser from electrical outlet.
2.Unplug Molex connector connecting switch to electrical box.
3.Remove the 2 screws anchoring the water level safety switch to the bottom of the water level control mounting bracket.
