CAUTION
Risk of injury.
The compressor must be depressurised through connections A
and B before commencing any work and prior to connecting to the
refrigerant system.
ATTENTION Property damage possible.
The compressor as delivered is equipped with Schrader valves on
the high and low pressure connections. These are used exclusively
for changing with inert gas in the factory, and under no circum
-
stances may they be connected to the refrigeration circuit (the
Schrader valves are approved for overpressure up to 28 bar only)!
INFO
Optionally to the flange shut-off valves, cutting ring screw joints
(Fig.17 and 18) (HP/LP) are also available.

Pipes and system components must be clean and dry inside and free of scale, swarf and layers of
rust and phosphate. Only use hermetically sealed parts.
Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being
cracked and broken by severe vibrations.
Ensure a proper oil return.
Keep pressure losses to an absolute minimum.
