6.8 Decompression valves

Fig. 27
ATTENTION The compressor is fitted with two decompression valves. One
valve each on the suction and discharge side. If excessive pres-
sures 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
conditions can occure, which may result in a permanent leak.
Always check system for refrigerant loss after activation of pres-
sure 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
