Check the refrigerant charge in the system:
-
After the air conditioning system has been operating for approx. 5 min. with the electromagnetic clutch activated and the engine
running at a rapid idle, the refrigerant should flow through the sight glass without forming any bubbles.
During the cold season:
-
To prevent the shaft seal of the compressor from drying out and leaking, operate the air conditioning system for approx. 15 min.
twice a month at ambient temperatures above 46°F (8°C).
The refrigerant receiver as well as all components of the air conditioning system should be visually inspected during the maintenance
activities. Special attention should be directed to any signs of corrosion and mechanical damage.
All components that are not in perfect condition must be replaced for safety reasons.
CAUTION
The pressure vessels directive requires the operator to have the refrigerant receiver checked by an authorized service
professional at regular intervals.
Note
To ensure trouble free operation of the air conditioner, the refrigeration oil and filter drier must be replaced 6 months after the initial
operation of the vehicle or if there is a change in color of oil.
a) Yellow
– Normal oil
b) Black
– Carbonized oil
c) Brown
– Copper Corrosion, due to moisture in system
d) Metallic Gray
– Suspended metallic particles
The filter drier should be replaced every year at the beginning of the season or every time system is exposed to contamination.
These activities must be performed by an authorized service company which should also perform a functional check of the air
conditioner as well as a leak test of the system.
Warranty claims can only be accepted if the claimant can prove that the maintenance and safety instructions have been strictly
observed.
