INSTALLATION INSTRUCTIONS
TEMPERATURE CONTROL ALTITUDE ADJUSTMENT:
REQUIRED TOOLS:
• Allen Wrench (5/64”)
• Torx Screw (T-7)
The scale to the right may be used as a guide for measuring degrees of rotation required for altitude
correction. The arrows indicate direction of screw rotation. See Figure 1.
IMPORTANT: Upright models ordered with “High Altitude” temperature controls are
pre-calibrated and do not require adjustment.

INSTRUCTIONS: DANFOSS TEMPERATURE CONTROL ADJUSTMENT FOR
HIGH ALTITUDE APPLICATIONS
STEP 1 - Unplug cooler.
STEP 2 - Remove the screws that secure the temperature control to the inset box.
STEP 3 - To make these adjustments it may be necessary to remove the temperature control from the housing.
NOTE: You may have to remove the wires attached to the control. Take note as to which wire is on which spade terminal.
STEP 4 - 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.
STEP 5 - 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 6 - Make sure to reconnect the wires to the proper spade terminal when reinstalling.
INSTRUCTIONS: CUTLER HAMMER TEMPERATURE CONTROL ALTITUDE ADJUSTMENT
STEP 1 - Unplug cooler.
STEP 2 - Turn the temperature control to the “9” position.
STEP 3 - Remove the screws that secure the mounting plate to the evaporator top. See Figure 2.
STEP 4 - Pull control down gently from housing.
STEP 5 - Turn screws counterclockwise (CCW).
STEP 6 - Reassemble to cooler housing and return the temperature control to the “5” position.
