IV. a - PRESTART CHECKS:
The compressor must float freely before connecting
to electrical power. The compressor motor is
provided with rubber vibration isolator mounts (no
springs). No bolts need to be loosened. Check all
exposed refrigeration lines to make sure they are not
dented or kinked. Check for tubing shifts due to
shipping that would cause operating noise, wear, or
leaks. Check that condenser fan rotates freely.
The refrigeration system should be checked for
proper operation before product is stored in the
cabinet.
IV. b - TEMPERATURE CONTROL:
The temperature is set at the factory but local
conditions may necessitate slight adjustment.
The temperature control shown in figure 11 is located
on the right side of the evaporator housing. To
adjust, turn the adjustment screw with a screwdriver
a small amount at a time; turning clockwise lowers
the temperature. An "OFF" position is fully
counterclockwise and interrupts power to the
compressor and condenser fan only, not the entire
refrigerator.
IV. c - DEFROST CONTROL:
Frozen food storage cabinets are equipped with a
defrost timer (figure 12) that provides a 20-minute
defrost cycle every 6 hours (four defrost cycles per
day).
This control can be adjusted to set when the next
defrost cycle will start. To adjust the defrost time
control, use a coin on the outside slot in the rim of
the timer and turn clockwise until the compressor
turns off. Continue turning coin clockwise until the
