6) Bin Control
MODELS WITH THERMOSTAT
CAUTION
When the ambient temperature is below 45°F, the Bin Control Thermostat
operates to stop the icemaker even if the Ice Storage Bin is empty.
When the Thermostat is set in the prohibited range, the icemaker oper-
ates continuously even if the Ice Storage Bin is filled with ice. Setting in
the prohibited range might cause severe damage to the icemaker result-
ing in failure.
No adjustment is required under normal use, as the Bin Control is factory-adjusted.
Adjust it, if necessary, so that the icemaker stops automatically within 10 seconds after
ice contacts the Bin Control Thermostat Bulb.

5) Freeze Timer
CAUTION
Adjust to proper specification, or the unit may not operate correctly.
Two new dip switches numbered 9 and 10 have been added to the improved “E”
board to better prevent possible freeze ups. These settings come factory set to the
default setting of 60 min. (OFF, OFF). Check the adjustment chart published in the
Tech Specs for proper settings. If the old board does not have these two dip
switches, (only 8 instead of 10), leave setting as OFF, OFF.
