STARTUP

A.  The compressor is ready to operate. Plug in the cooler. 
B.  Temperature controls are factory-set to give refrigerators 

an approximate temperature of 35°F (1.7°C) and freezers 
an approximate temperature of -10°F (-23.3°C). Allow unit 
to function several hours, completely cooling cabinet before 
changing the control setting. 

 

Temperature Control Location and Settings.

 

•  Electronic control with display: 

- In or behind bottom louvered grill

 

See website for adjustments, sequence of operation, and 
more information.

C.  Excessive tampering with the control could lead to service 

difficulties. Should it ever become necessary to replace 
temperature control, be sure it is ordered from your TRUE 
dealer or recommended service agent. 

D.  Good air flow in your TRUE unit is critical. Be careful to 

load product so that it neither presses against the back wall, 
nor comes within four inches of the evaporator housing. 
Refrigerated air off the coil must circulate down the back wall.

NOTE:

 If the unit is disconnected or shut off, wait five minutes 

before starting again.

RECOMMENDATION

 - Before loading product we recommend 

you run your TRUE unit empty for two to three days. This allows 
you to be sure electrical wiring and installation are correct and no 
shipping damage has occurred. Remember, our factory warranty 
does not cover product loss!

LIGHT SWITCH LOCATION: 

Light switch location depends 

upon the GDM model. Most GDM models will have the light switch 
located on the right side of the ceiling inside the unit.
