TEMPERATURE CONTROL INSTRUCTION
1. Plug in and the Display panel will be lighted and make a beep sound.
The compressor will begin to run.
2. The compressor is automatically cycled by the electronic controller (PCB).
3. The Defrost cycle is automatically controlled by the PCB.
4. Good Air Flow in refrigerator unit is critical. Be careful to load product so that it neither
presses against the back wall, nor reaches within four inches from the evaporator
compartment.
- By pushing the up/down button, you can set the inside temperature.
- If you want lower temperature, push the Down button to be lighted lower level numbers.
When the inside temperature is lower than -45ºC, the panel will display ‘ ’
and higher than + 18ºC, the panel will display ‘’.
