TEMPERATURE CONTROL ADJUSTMENT FOR HIGH ALTITUDE ONLY!

TERMS: __________ STEP 4 ___________

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 evaporator fan housing in the ceiling of the cabinet. See image to the right for temperature control location.

__________ STEP 3 ___________

Pull out gently from cabinet.

NOTE:

Mechanical temperature controllers 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

For high elevation installa- tions, 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.
