Delivery condition 1 (from the factory):
Cylinder cover prepared for capacity regulator.

Fig. 24

Before  commissioning,  the  blind  flange  with 
screws must be removed and replaced by the 
new  set  capacity  regulator  with  O-ring  joints 
and screws. Observe position and construction 
of the capacity regulator.

Attention! Compressor is under pressure!
Depressurize the compressor first.
