Operation Instructions – Glass Frosters
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 bot-
tom of the evaporator. The defrost cycle lasts for
approximately 20.
During normal operation it is recommended that
the doors are not left open to prevent excessive
frost buildup on the coil.
Temperature Control
An adjustable temperature control is located inside
the froster on the evaporator fan panel assembly.
Approximate temperature operating range: minus
15° F. minimum and plus 10° F. maximum. Make
adjustments as shown to attain the desired
temperature.
■ 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 counterclock-
wise to the “O” position until a click is
noted.
The condenser fan motor turns off and on with
the compressor. The evaporator fan motor runs
continuously, except during the 20 minute
period of the four-hour defrost.
