Compressor
FUNCTION
The compressor is suction the vapors com-
ing from evaporator at low temperature and
pressure, compress them and transmit the gas
at high temperature and pressure towards con-
denser.
The refrigerant fluid in entering in condenser
in vapors condition, at high temperature and
pressure, where, by condensing, is transmitting
in the external environment the abstracted heat.
At condenser exit, the refrigerant fluid is in
liquid condition, at high pressure and tempera-
ture.
DISMOUNTING
Drain the refrigerant circuit to a charging
station.
Disconnect the battery.
Disconnect the supply wiring connector of
the compressor clutch.
Dismount the screw of attachment clamp
of the refrigerant pipes on compressor.
Cover the open piping with protectors.
Dismount the compressor-driving belt.
Dismount the four compressor attachment
screws.
Extract the compressor.
REMOUNTING
In case compressor is replaced, this one is
delivered filled with oil.
Position the compressor with the filling cap
upwards.
Mount the compressor attachment screws.
Tighten the compressor attachment screws
to the required moment of
2,1 daNm
.
Remount the two refrigerant pipes and
tighten the attachment clamp screw to the re-
quired moment of
1,2 daNm.
Mount the compressor-driving belt and ten-
sion it by acting upon the screw (
1
) according
to the method described in chapter
07 “ Ac-
cessories belts tensioning ”.
The tensioning values are :
150 - 155 Hz - compressor belt;
214 – 230 Hz – DA pump/compressor belt.
Connect the supply wire connector of the
compressor clutch.
Vacuum and fill the circuit with refrigerant
fluid
HFC 134a
, by means of the charging sta-
tion ( see chapter 62 “Draining – Filling unit
refrigerant circuit” ).
REMARK :
Before mounting check the condition
of the gaskets and lubricate them with
compressor oil PAG SP 10.
