TERMS:
Cut-out - Temperature sensed by the
controller that shuts the compressor
off.

STEP 1
Unplug the cooler.
STEP 2
Remove the screws that secure the
temperature control to the evapora-
tor fan housing in the ceiling of the
cabinet. See image to the right for
temperature control location.
STEP 3
Pull out gently from cabinet.
STEP 4
For high elevation installations, it
may be necessary to "warm-up" the
set points. To make the adjustment,
insert the appropriate tool in each
adjustment screw and turn 1/4 of a
revolution clockwise (to the right).
This procedure will adjust both
the cut-in and cut-out about 2°F
warmer.
STEP 5
Make sure to reconnect the pink
wire to the proper spade
terminal when reinstalling.
NOTE:
Mechanical temperature
controllers are affected when func-
tioning at high altitude. The cut-in
and cut-out temperatures will be
colder than when the controller
functions closer to sea level
