TEMPERATURE CONTROL ADJUSTMENT FOR
HIGH ALTITUDE ONLY!
TERMS:
• Cut-out - Temperature sensed by
the controller that shuts the com-
pressor off.
• Cut-in - Temperature sensed by
the controller that turns the com-
pressor on.
TOOLS REQUIRED:
• Phillips head screwdriver
•
5
/
64
" or 2 mm Allen Key
• T-7 Torx Key
STEP 1
Unplug or disconnect power to the
cabinet.
STEP 2
Remove the screws that secure the
temperature control to the inset box
lower left side of the cabinet (when
facing the front of the cabinet).
STEP 3
Pull out gently from cabinet.
NOTE
Mechanical temperature control-
lers are affected when functioning
at high altitude. The Cut-in and
cut-out temperatures will be colder
than when the controller functions
closer to sea level.
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.
