THERMOSTAT
The thermostat is mounted in the machine compartment
at top or left side of front opening and the thermal ele-
ment is extended into the thermostat well. See Figure
10. The well is a cylindrical tube fastened to the exterior
of the inside tank, It is located near left front corner of
the machine compartment (left rear on single row).
NOTE: Caution must be exercised when replacing a
thermostat from thermal element tube so it does not
touch any of the refrigeration lines in the machinery
compartment. Because it senses the coldest tempera-
ture before attempting to change the range or the cut-
out point, make sure the thermostat thermal
element is properly inserted into the well to the red
mark. The correct distance from the end of the element
to the red mark on the element should be 22". Always
remember a poor contact will naturally affect the oper-
ating range and cabinet temperature. See table below.
The range and the cut-out point of differential can be
adjusted to settings other than those given in the table.
If a higher or lower range than is obtainable by the slot-
ted shaft is desired, change the adjustment screw
located between the two space connector behind the
control. Turn the adjustment screw clockwise to raise the
temperature, and counterclockwise to lower the range.

THERMOSTAT - Adjusting Screw
The differential adjusting screw is covered with a liquid
sealer which must be removed before any adjustment
can be made. Turn the differential screw clockwise to
lower the cut-in temperature and narrow the differential.
Turn the screw counterclockwise to raise the cut-in
temperature and widen the differential. Adjust the screw
only if has been proven that the thermostat differential is
too narrow — less than 9.5°F, or too wide, 14.5°F.
THERMOSTAT- Temp Adjustment
Thermostat dial is labeled #1 thru #7. #1 being warmest
and #7 being coldest. To lower cabinet temperature,
insert a dime or screwdriver in the slot provided and turn
clockwise.
