Excessive tampering with the control could lead to servicedifficulties. Should it ever become necessary to replacetemperature control, be sure it is ordered from your dealer orrecommended service agent.D. Good air flow in your unit is critical. Be careful to load productso that it neither presses against the back wall, nor comeswithin four inches of the evaporator housing. Refrigerated airoff the coil must circulate down the back wall.NOTE: If the unit is disconnected or shut off, wait five minutesbefore starting again.RECOMMENDATION - Before loading product we recommendyou run your unit empty for two to three days. This allows you tobe sure electrical wiring and installation are correct and no shippingdamage has occurred. Remember, our factory warranty does notcover product loss!LIGHT SWITCH LOCATION: Light switch location dependsupon the GDM model. Most GDM models will have the light switchlocated on the right side of the ceiling inside the unit. Most instancesthe switch is located next to the temperature control.

MECHANICAL TEMPERATURE CONTROLSCOIL SENSINGAn evaporator coil sensing temperature control ensures that the evaporator coil will remain clearof frost and ice by not allowing the compressor to restart until the coil temperature is above thefreezing temperature. This is considered an off cycle defrost.MECHANICAL TEMPERATURE CONTROL GENERAL SEQUENCE OF OPERATIONMECHANICAL CONTROL REFRIGERATOR GENERAL SEQUENCE OF OPERATION1. Cabinet is plugged in.a. Interior lights will illuminate on Glass Door Models only. If lights do not come on verify the light switch is in the “ON”position. Solid door cabinets may or may not have lights that may be controlled by the door switch.2. The compressor and evaporator fans will start if the temperature control is calling for cooling. (If the compressor does notstart, verify that the temperature control is not in the “OFF” or “0” position.)3. The temperature control may cycle the compressor and evaporator fan(s) on and off together.a. The temperature control is sensing the evaporator coil temperature.b. The temperature control should be set on the #4 or #5.c. The warmest setting is #1, the coldest is #9, and #0 is the off position.d. The thermometer is designed to read and display a cabinet temperature not a product temperature.The thermometer may reflect the refrigeration cycle swings of up and down temperatures.The most accurate temperature on a cabinet's operation is to verify the product temperature.4. There is not a defrost timer as the temperature control will initiate the off-cycle defrost during each refrigeration cycle.a. At this time, the compressor will and the evaporator fan(s) may turn off. Defrost heaters are not installed on refrigeratorsand therefore will not be energized.b. After the evaporator coil temperature has been reached, as determined by the temperature control, the compressor willrestart.5. There may be a timer located on the condensing unit base. This timer is not used for a defrost event. The timer will changethe rotation of the reversing condenser fan motor.12

WHEN TO MAKE AN ADJUSTMENT TO A MECHANICAL TEMPERATURE CONTROLWe advise to make a mechanical temperature control adjustment only for a high altitude location.HOW TO ADJUST A MECHANICAL TEMPERATURE CONTROLOPERATION INSTRUCTIONS:Scale Guide for MeasuringREQUIRED TOOLS: Jewelers Screw Driver (Small Screw Driver)50GE CONTROL INSTRUCTIONS:510RME RWA45The scale to the right may be used as a guide for measuringdegrees of rotation required for altitude correction. See Figure 1.The arrows indicate direction of screw rotation. Turn calibrationscrew clockwise to obtain warmer operating temperatures.NOTE: Each 1/4 turn of the calibration screw is equal toapproximately 2 degrees F. Do not make more than 3/4 turn.After making adjustment, measure temperature during threecycles before adjusting again.NOTE: Only adjust the screw(small flathead) on the face ofthe control (next to the cam).See Figure 3.Follow the Altitude CorrectionTable to the right.CO40LD E R351202530Altitude CorrectionAltitude ise Turns7/6011/6015/6019/6023/6027/6030/6034/6037/60 Torx Screw (T-7)2Front of Temperature ControlCalibrationScrewTo adjust the temperature controltake the control knob off to view thecut-in screw.

INSTRUCTIONS: DANFOSS TEMPERATURE CONTROL ADJUSTMENT FORHIGH ALTITUDE APPLICATIONSSTEP 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 theappropriate tool in each adjustment screw and turn 1/4 of a revolution clockwise (to the right). This procedure will adjust boththe cut-in and cut-out about 2 F warmer.STEP 6 - Make sure to reconnect the wires to the proper spade terminal when reinstalling.INSTALLATION INSTRUCTIONSTEMPERATURE CONTROL ALTITUDE ADJUSTMENT:Scale Guide for MeasuringREQUIRED TOOLS: Allen Wrench (5/64”) Torx Screw (T-7)36090The scale to the right may be used as a guide for measuring degrees of rotation required for altitudecorrection.
