Attention:
- If there is a refrigerant leak, ventilate the room before topping up the system.
- Additional information on safe handling of refrigerant and compressor oil can be obtained from their instructions for use.
- When replacing some components of the air conditioning system, it is necessary to add compressor oil to the system (SP-10).
* (right hand drive models): the amount of compressor oil in the installed compressor must match the amount of oil in the removed (the new compressor is filled with approximately 50 ml of compressor oil).
Vacuum system
1. If the air conditioning system has been depressurized for any reason, it is necessary to evacuate it using a refrigerant filling station. If the system has been depressurized for several days, the condenser dryer should be replaced and a vacuum should be carried out.
2. Connect the refrigerant filling station (1) to high pressure valve (2) and low pressure valve (3), as it shown on the picture. Vacuum the system.
3. If the pressure in the low pressure valve does not reach 93.5 kPa within fifteen minutes, then there is probably a leak in the system. Partially charge the system with refrigerant and check for leaks (see "System leak test").
Charging the system with refrigerant
1. Connect the refrigerant station to the high pressure valve and the low pressure valve.
2. Vacuum the system (see "Vacuum system").
3. Add the same amount of compressor oil that was removed from the system.
4. Charge the system with the appropriate amount of R-134a refrigerant. Do not allow excess refrigerant when charging, because. the compressor may be damaged.
- The amount of refrigerant - 400 - 450 g.
5. Check for leaks (see "System leak test").
6. Check system performance.
System leak test
1. Check the system using a leak detector.
2. If leaks are found, it is necessary to repair or replace parts at the leaks (hoses or clamps).
3. After checking and repairing leaks, the system must be evacuated.
