Operation Instructions – 
Single Door Freezer
Defrost System - Hot Gas Defrost
This system consists of a six-hour, as well as a
four-hour defrost cycle which includes a 20 minute
evaporator defrost. 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, the evaporator fan, and 
the automatic four hour defrost timer.
To activate the six hour defrost system, 
depress the defrost switch located on the 
front grille 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 unit.
The Four Hour Defrost Timer:
This timer ensures that frost will not buildup on 
the evaporator coil. Every four hours the hot gas
by-pass valve is opened and hot gas is 
circulated through the evaporator coil. The 
defrost is terminated when the coil is clear of 
frost. 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.
Temperature Control
An adjustable temperature control is located inside
the freezer 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 and the evaporator fan motor
turns off and on with the compressor.
