Thermostatic expansion valve
Its function is to reduce the refrigerant fluid
pressure at the evaporator entrance, to a default
value. In this way, the fluid passing through the
evaporator may be suction by the compressor
in a complete gaseous condition.
DISMOUNTING
Drain the refrigerant circuit by means of the
charging station .
Dismou nt :
- attachment nut ( A) of the connection
pipes;
-two attachment screws ( B) of the
expansion valve ( C) on evaporator.
REMOU NT I NG
When remounting, replace the pipes sealing
gaskets. The require d tightening moment for B
screws is of 0,8 daNm.
The required tightening moment for A pipes
