INSTALLATION / OPERATION INSTRUCTIONS

TEMPERATURE CONTROL ADJUSTMENT FOR HIGH ALTITUDE / DEFROST OPERATIONS

TEMPERATURE CONTROL:

(Temperature Control Adjustment For High Altitude

Only!)

Temperature control is located at the back of the unit next to the rear grill. A flat head screw driver will need to be used when adjusting the temperature of the unit. (See image 1).

TERMS:

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

Cut-in - Temperature sensed by the controller that turns the compressor on.

REQUIRED TOOLS:

•Phillips Head Screwdriver

•5/64" or 2 mm Allen Wrench

•T-7 Torx Wrench

STEP 1

Unplug the cooler.

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.

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.
