Coolant
When working with refrigerant, wear protective glasses and gloves to avoid the risk of frostbite. Do not work with refrigerant near flames or very hot objects (for example, cigarettes), to eliminate the risk of inhaling toxic fumes.
Work in a ventilated area.
Handle used compressor lubricant with care as it may contain acids.
Depressurization of the circuit
To eliminate the risk of moisture getting into the system, close all pipes immediately; for the same reason, new parts should be at ambient temperature before unpacking.
The plugs of the connecting elements of the tubes/parts should be removed immediately before their installation.
The dehumidifier tank should not be left in the open air for more than 5 minutes (even when connected to the circuit) to avoid saturation with air and moisture.
If the circuit remains connected to open air, it is necessary to replace:
- dehydrator tank;
- compressor oil.
Air conditioning compressor
When working with the compressor, the following rules must be observed:
- do not lift the compressor by the fittings or by the pulley;
- do not place the compressor resting on the pulley;
- avoid hitting the pulley or fittings (fragile materials);
- do not allow compressor oil, refrigerant or other lubricants to come into contact with the compressor clutch.
Air conditioning compressors should be stored indoors at temperatures between 5°C and 50°C. The plastic plugs supplied with a new air conditioning compressor can be reused periodically.
Caution: When turning on the air conditioner compressor for the first time, do not exceed 1500 rpm for the first minute of operation to allow the oil to spread throughout the system.
Installation of tube connecting elements
Use only new gaskets. Lubricate gaskets with compressor oil.
Tighten the fittings to the recommended torques, using a counter wrench if necessary.
General precautions for the circuit
Warning: Do not operate the air conditioning system if the refrigerant has been drained from the circuit.
Do not remove the compressor refrigerant fill plug when the circuit is filled.
Checking electrical connections
Before connecting the connector, check:
- status of various contacts (deformation, oxidation, etc.);
- presence of a sealing gasket;
- the presence and quality of mechanical locking.

During electrical inspections:
- the battery must be charged;
- it is prohibited to use sources with voltage higher than 16 V;
- it is prohibited to use the indicator lamp;
- it is prohibited to create an electric arc.
Do not disconnect:
- battery with the engine running;
- ECU with ignition on.
