Frost Top Serving Counter Operation
Frost top counters are designed to maintain an even layer
of frost to pleasantly display product. Once turned on, the
compressor will run continuously. There is no temperature
control. The ON/OFF switch is the only means available to
cycle the unit.
Since it takes time for the frost to accumulate initially, the
unit should be turned on approximately one hour before it
is required. Product should not be placed on the frost top
prior to turning the unit on, because it may freeze to the
surface of the unit.
The unit must be turned off when not in use or overnight
for defrosting and cleaning.
Refrigerated Cold Pan with LiquiTec Serving
Counter Operation
Note
The cold pan is not intended to be used with ice.
There is a switch on the compressor housing front to turn
counters on and off. Turn it off when not in use or overnight
for defrosting and cleaning.
The are adjusted at the factory to provide proper operation
without any further adjustments.

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.
Temperature Alarm
The alarm will sound and flash HI or LO 90 minutes after the
unit has reached its alarm temperature point or after any
power interruption if the temperature is above or below the
alarm set points.
