READ THIS MANUAL CAREFULLY BEFORE CARRYING OUT ANY OPERATIONS ON THE COMPRESSOR 
UNIT. 

 

THIS MACHINE MUST BE CONNECTED TO TWO DIFFERENT POWER SUPPLIES: THREE-PHASE OR SINGLE-
PHASE SUPPLY FOR THE COMPRESSOR AND SINGLE-PHASE SUPPLY FOR THE DRYER

 

 
 
 

 

THIS MACHINE IS DESIGNED FOR BOTH CONTINUOUS AND INTERMITTENT WORKING, 

HOWEVER TO AVOID CONDENSATION PROBLEMS IN THE OIL, THE MACHINE MUST OPERATE 

CONTINUOUSLY IN LOAD FOR AT LEAST 10% OF THE TIME, CHECK FOR SIGNS OF 

CONDENSATION IN THE OIL BY FOLLOWING THE INSTRUCTIONS GIVEN IN CHAPTER 15.2
