CAUTION
Discharging refrigerant gas near open flame is
extremely dangerous and may result in the
emission of toxic gas (phosgene).
Tighten the
RED
(B)
charge pipe union and the
BLUE (A)
intake pipe union.
Recover the refrigerant gas and then perform the
system vacuum cycle
.
The specified vacuum values must be attained
during the system vacuum cycle.
This operation is very important to ensure system
efficiency.
Check that the vacuum does not increase by
33
mbar (25 mmHg)
in
5 minut
es. If these values
are not attained, there is a leak in the system.
Check for leaks with an electronic leak detector.
CAUTION
Do not use open flames to search for refrigerant
leaks, as this may generate toxic gas (phosgene).
In the event of removal of any system components,
repeat the system vacuum cycle
and check
for
leaks.
Charging the air conditioning system
After
discharging the system
, attach the special tool to the system discharge/recharge unions and recharge
the system.
If some of the compressor oil has remained trapped in the machine after the discharging procedure, top up
the system with the same quantity of the specified oil.
When replacing a component, the new component must be topped up with the same amount of oil removed.
Carry out the
system charging
cycle.
Approximately
670 ± 30 g
of refrigerant is needed to completely charge the system.
FROM Ass.ly No. 90177
, the quantity of refrigerant needed for a full charge is
630 ± 30 g
.
While charging the system, if pressure equilibrium is reached before charging is complete, proceed as follows:
- start the engine and run at
2000 rpm
;
- switch on the A.C. system, set to max. cold and select max. fan speed;
- close the doors.
When the charging procedure is complete, let the system run for about
10 minutes
.
After 10 minutes of operation at
MAX
cooling level, the following conditions must be met:
- ambient temperature:
20 - 22°C
;
- relative low pressure:
2.0 bar
;
- relative high pressure:
13.5 bar
;
- output air temperature (average measured at the vents):
8 - 13 °C
.
