9.14 Inspection of the compressor stage
Fig. 29
Danger
Only perform checks and carry out work on the
screw compressor when the unit is out of
operation, depressurized, and secured from being
switched on again!
Caution when draining hot water: risk of scalding!
Allow the unit to cool down first.
Important
When removing the cover, water (1-2 litres) may
escape from the compressor. Please place an
appropriate vessel underneath it to collect the
water.
Perform an inspection as follows:
•
Shut down the machine.
•
Switch the screw compressor unit off and ensure
that it is depressurized, electrically isolate and
locked off.
•
Remove the retaining bolts from the side cover of
the compressor and take off the cover (1- Fig. 29).
•
Assess the condition of the compressor. The
inspection plan describes everything you need to
consider.
•
Attach the side cover with a new seal. Insert the
screws to a torque of 25 Nm.
•
Check the water level on the water level indicator
(-6- Fig. 16) and add water if necessary (see
Chapter 6.5 Water supply).
