Section 2 Installation Instructions
Part Number 14514 2/08 2-7
ADJUSTING DEFROST DURATION
The defrost cycle is terminated by a temperature-
sensing switch located on the suction line, adjacent to
the evaporator coil.
The defrost duration is factory-set. Normally, no
adjustment is required. For a longer defrost time, press
down on the inner dial pointer and rotate the pointer until
the desired time lines up.
TEMPERATURE CONTROLS
The temperature controls are factory-set to maintain an
average temperature of 38
°F in refrigerators, and an
average temperature of 0
°F in freezers.
The temperature variance is 6-8 degrees. A freezer
should run between -2 to -3
°F and +3 to +4°F. A
refrigerator should run between +35 to +36°F and +41 to
+42
°F.
For a different cabinet temperature setting, turn the
temperature control knob or screw, located on the
evaporator coil/blower housing.
Important
The coil defrosts only until the temperature-sensing
switch terminates the cycle, regardless of the
defrost duration that is set.
Important
Setting the temperature control to the coldest setting
may cause the coil and/or air ducts to freeze and ice
up. This will eventually result in a warmer cabinet
temperature.
If ice accumulation occurs and the temperature is
lower than the guidelines, turn the control knob to a
warmer setting.
! Caution
Allow the cabinet to reach proper operating
temperature before filling it with product. Do not
place hot or steaming foods in the cabinet.
! Caution
Store products with high acid content (such as
lettuce, other fresh vegetables or fruits, salad
dressings, etc.) in closed containers. This will
prevent corrosion on the evaporator coil and other
metal parts in the air distribution system.
