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.15 and 16) (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.
