5) Freeze Timer
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.

6) Bin Control
MODELS WITH THERMOSTAT
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 operates con-
tinuously even if the Ice Storage Bin is filled with ice. Setting in the prohib-
ited range might cause severe damage to the icemaker resulting in failure.
No adjustment is required under normal use, as the Bin Control is factory-adjusted. Ad-
just it, if necessary, so that the icemaker stops automatically within 10 seconds after ice
contacts the Bin Control Thermostat Bulb.
