COMPRESSOR LUBRICATION 

 

8.7.1

 

GENERAL RECOMMENDATIONS 

 

CAUTION! 

Before  performing  any  operation  involving  draining  or  topping  up  compressor  oil, 
unplug the compressor and wait until the system has reached atmospheric pressure. 
 

Use adequate protection when handling lubricants. 

 
We  recommend  a  lubricant  compatible  with  the  ISO  VG  46  oil  (mineral-based  oil)  used  during 
testing. The pour point must be at least -8+10°C and the flash point higher than +200°C. 
 

Oilscrew plus 46 

 

For use of incompatible oils, follow the procedure described in chapter 8.8

 

 

Never mix different types of oil 
 

We recommend using oil with a VG32 (-10°C / 0°C) rating for cold climates and VG68 for tropical 
climates (+20°C / +50°C). 
 
Before  starting  up  compressors  without  oil,  feed 

approximately  0.1  lt 

of  lubricant  in  through  the 

regulator intake opening while keeping the suction valve shutter lowered and manually turning the 
screw rotors in the right direction. 

 
 

CAUTION! 
When lowering the suction valve shutter be careful not to damage the throttle valve O-
ring. 

 

 

 

Feed the mineral-based lubricant into the oil tank using the special top-up hole and fill until the 
right level is read on the window.  

 
 
 

 

Start  up  the  compressor,  initially  switching  it  on  and  off  sequentially  and  quickly  and  then 
starting it up.    

 

 

 

Once initially filled with oil, turn off the compressor, vent the pressure and, if necessary, top up 
the lubricant from the top-up hole until the right level is read on the window.
