AND 

SERVICE 

 
Before any service verify that the power has been removed from the 
system 
 

6.1 ABSORBER 

REMOVAL 

The service interval of the absorber of the M600 is 20,000 hours (27.4 
months).

   

 

The M600 absorber has been placed at the front of the unit, behind a 
removable cover, to facilitate replacement.  Absorber replacement 
should take about 15 minutes.  This is ideal for rack and rail mounted 
compressor units. 

 
6.2 HELIUM 

PRESSURE 

ADJUSTMENTS 

The helium charge can be increased or decreased by using the ¼” self-
sealing connector on the front of the unit, this connection is marked 
by a white washer. 
 
Never charge the compressor above a static pressure of 250psi 
(17.2bar)
