Icemaker System ON/OFF
All units with icemakers are shipped with the icemaker system switched OFF. By pressing the ICE ON/OFF key on
the control panel, power is allowed to the icemaker system, and “ICE” appears on the LCD (See Figure 3-9). To
disable the icemaker system, press the ICE ON/OFF key again and “ICE” will disappear from the LCD indicating the
icemaker system is OFF.
NOTE: When unit is in “Sabbath Mode,” icemaker system is disabled. Sabbath Mode will be covered later.
NOTE: To allow ice to freeze fully and reduce effects of low water pressure, power to the icemaker system is inter-
rupted for 45 minutes after each ice harvest. This can be bypassed for service purposes by pressing the ICE
ON/OFF key to switch the icemaker system OFF, then back ON.
