the MAX ICE key on the control panel, the ice maker system is switched ON (if OFF); multiple ice cube icons appear
in the LCD (See Figure
the freezer evaporator fan is switched to 100% run for twenty-four (24) hours, switching off only when the door is
opened.
After twenty-four (24) hours, the freezer set-point reverts to the last manually input set-point, the freezer evaporator
fan resumes its normal operation (cycling with the compressor); and two of the three ice cube icons disappear from
the LCD, indicating normal ice production has resumed.
NOTES:
• When the maximize ice production feature is active, power to the icemaker system is NOT interrupted after ice
harvest, so the icemaker will initiate a harvest as soon as the thermostat reaches 10°F (-12°C).
• Switching the unit OFF, then back ON with the POWER key, or pressing the MAX ICE key during the twenty-four
(24) hour production period will switch the maximize ice production feature OFF.
• When in Sabbath Mode, the icemaker system is disabled. Sabbath Mode will be explained later.
