Temperature Control - Perlick FR48 SS Installation & Operation Manual

Defrost System
This system consists of a six-hour, as well as
a four hour defrost cycle. The six hour defrost
cycle is manually activated and automatically
terminated, while the four hour cycle is completely
automatic.
The Six Hour Solid-State Defrost Timer
This timer shuts off the power to the condensing
unit, door frame heater, evaporator heater, and the
automatic four hour defrost timer, while it supplies
power to the evaporator fan.
To activate the six hour defrost system, depress
the defrost switch located on the front grill of the
cabinet. An amber light will illuminate and the
defrost cycle will begin. When the defrost cycle
ends, the light goes off and the cabinet resumes
normal operation. To manually cancel the defrost
cycle, momentarily turn off the electricity to the
machine.
The Four Hour Defrost Timer
This timer ensures that frost will not buildup on
the evaporator coil. Every four hours it shuts
down the condensing unit and evaporator fan and
supplies power to the defrost element clamped to
the bottom of the evaporator. The defrost cycle
lasts for approximately 20 minutes.
During normal operation it is recommended that
the doors are not left open to prevent excessive
frost buildup on the coil.
Perlick is committed to continuous improvement. Therefore, we reserve the right to change specifications without prior notice.

Temperature Control

An adjustable temperature control is located inside
the Bottle Cooler on the evaporator fan panel
assembly. It is factory set at approximately 38˚F
for standard refrigeration and approximately 30˚F
for low temperature models. Make adjustments as
detailed below to attain the desired temperature.
NOTE: A temperature setting that is too low will
not allow enough condensing unit "off" time to
maintain a frost-free coil.
■ Colder Temperatures: Turn the adjusting
screw clockwise (to the right)
■ Warmer Temperatures: Turn the adjusting
screw counterclockwise (to the left).
■ Temperature Control "OFF": Turn the
adjusting screw completely counterclockwise
to the "O" position until a "click" is noted.
The condenser fan motor turns off and on with
compressor. The evaporator fan motor runs
continuously, except during the 20 minute period
of the four-hour defrost.
