REFRIGERATION SERVICE

General Information:

Work on the refrigeration system should only be done when it is certain that the system needs repair.

￿Refrain from checking refrigeration

 

 

pressures without reason. Visual inspection

 

 

of the water system, observation of the ice

 

 

formation, amp draw, voltage, and other

 

 

techniques will lead to proper diagnosis.

 

 

Scotsman also recommends that, at the time of

 

 

initial start up, gauges not be used.

 

 

￿If gauges must be used, don’t always check the

 

 

high side pressure. If the condenser is clean and

 

seems to be operating correctly, it most likely is.

 

The low side pressure is more important on an

 

 

ice machine than the high side.
