Attention:
- If a refrigerant leak occurs, ventilate the room before recharging the system.
- Additional information on safe handling of refrigerant and compressor oil can be obtained from the instructions for use.
- When replacing some components of the air conditioning system, it is necessary to add compressor oil (SP-10) to the system.
* (right-hand drive models): the amount of compressor oil in the installed compressor must match the amount of oil in the removed one (the new compressor contains approximately 50 ml of compressor oil).
Vacuuming the system
1. If the air conditioning system has been depressurized for any reason, it must be evacuated using a refrigerant filling station. If the system has been depressurized for several days, the condenser dryer must be replaced and evacuated.
2. Connect the refrigerant charging station (1) to the high pressure valve (2) and low pressure valve (3) as shown in the figure. Evacuate the system.
3. If the pressure in the low pressure valve does not reach 93.5 kPa within fifteen minutes, there is probably a leak in the system. Partially charge the system with refrigerant and check for leaks (see "Testing the system for leaks").
Charging the system with refrigerant
1. Connect the refrigerant charging station to the high pressure valve and low pressure valve.
2. Evacuate the system (see "Evacuating the 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 overcharge the refrigerant, as this may damage the compressor.
- The amount of refrigerant is 400 - 450 g.
5. Check for leaks (see "Checking the system for leaks").
6. Check the system performance.
Checking the tightness of the system
1. Check the system using a leak detector.
2. If leaks are detected, it is necessary to repair or replace parts at the leak sites (hoses or clamps).
3. After checking and eliminating leaks, the system must be evacuated.
