Fig. 26

ATTENTION The compressor is fitted with two decompression valves. One valve

each on the suction and discharge side. If excessive pressures are
reached, the valves open and prevent further pressure increase.
Thereby CO

is blown off to the ambient!

In the event that a pressure relief valve activates repeatedly, check
valve and replace if necessary as during blow-off extreme con-
ditions can occur, which may result in a permanent leak. Always
check system for refrigerant loss after activation of pressure relief
valve!
The decompression valves do not replace any pressure switches
and the additional safety valves in the system. Pressure switches
must always be installed in the system and designed or adjusted in
accordance with EN 378-2 or appropriate safety standards.
Failure to observe can result in risk of injury from CO
