The condenser must be cleaned at regular intervals
to remove dust, insects and other particle. Make
cleaning easier by moving the condenser sideways.
Check for leakages in condensator, in expander or
in hoses and connectors.. Check also the
cleanliness of the exit pipes of the condensation
water.
WARNING: Avoid contact with the
refrigerant. If refrigerant enters the
eyes a doctor should be contacted
without delay. Welding work should
not be carried out near to the air
conditioning system as poisonous gas may be
released. The maximum temperature permitted in
the vicinity of the refrigerant pipes is 80˚C.
If the air conditioning is not running properly, have
an authorized workshop check the system.
On the upper part of the receiver (1) of the air
conditioning system there is a sight glass A and
moisture eliminator/indicator (B).
Sight glass A (run the engine at 1500 rpm, air
conditioner at max. cooling for a few minutes):
No bubbles appear at all. EXCESSIVE
REFRIGE-RANT. The high---pressure side
(2) will be abnor-mally hot. Contact an
authorized workshop.
The fluid inside is almost transparent. A few
bubbles may appear as the engine speeds
up and down. SUFFICIENT
REFRIGERANT. The high-pressure side
(2) will be hot and the low-pressure side (3)
cold.
A few bubbles appear intermittently, at
intervals of 1 to 2 seconds. INSUFFICIENT
REFRIGERANT.
The high-pressure side (2) will be warm,
and the low-pressure side (3) fairly cold.
Contact an authorized workshop.
Bubbles flow continuously, and when the
refrigerant is almost exhausted a ”mist” like
flow will be seen, with no bubbles visible.
VERY LITTLE REFRIGERANT. There will
be almost no difference in temperature
between the high-pressure side (2) and the
low-pressure side (3) near the compressor.
Contact an authorized workshop.
NOTE: Refrigerant must be colourless. If it is brown
or yellow, it must be changed. Contact an
authorized workshop.
The colour of the moisture eliminator/indicator (B)
has to be blue or green depending on the
manufacturer. If it is pink replace the receiver.
Contact an authorized workshop.
