Operation
8100-EF(N)P & 8100-FAP Series Operation
Note
The cold pan is not intended to be used with ice.
There is a switch on the compressor housing front to turn
the 8100-EFP units on and off. The unit must be turned off
when not in use or overnight for defrosting and cleaning.
8100-EFP Series LiquiTec® Eutetic fluid cold pans are
adjusted at the factory to provide proper operation without
any further adjustments.
The temperature control is located on the condensing
housing.
Power Switch & Temperature Control
1. At initial start-up or anytime power is disconnected,
then reconnected to the unit, the control will go into
normal cooling mode.
2. The temperature control will cycle the compressor and
condenser fan motor to maintain proper temperature.

Error will go away if the
control cycles off the
compressor or if the
power is shut off. If error
is on a cold pan it could
be related to a high
ambient temperature or
not shutting the rail off
nightly.
All alarms sound for approximately 10 seconds and then
are silent for 50 seconds. It will do that for 15 cycles and
then remain silent. The alarm code will still be present on
the display until the fault clears.
