1. Do not work with refrigerant in an enclosed space or near an open flame.
2. Always wear safety glasses.
3. Be careful not to get refrigerant in your eyes or on your skin.
On defeat:
- A) Do not rub the burned area.
- b) Rinse the burnt area with plenty of cold water and lubricate the skin with petroleum jelly.
- V) Do not try to treat yourself, contact a medical facility immediately.
4. Do not heat or incinerate refrigerant cylinders.
5. Do not drop cylinders or subject them to shock.
6. Do not run the compressor without enough refrigerant. Lack of refrigerant leads to insufficient lubrication of the compressor, which can lead to compressor failure.
7. Do not open the high pressure valve on the gauge block while the compressor is running. If the high pressure valve is open, the direction of refrigerant flow will change, resulting in compressor failure.
8. Do not open the high pressure valve on the gauge block while the engine is running. When the valve is open, high pressure is generated which can cause cylinders to explode and cause serious injury.
9. Do not overcharge the system. Excess coolant leads to insufficient cooling, excessive fuel consumption, engine overheating, etc.
10. Use only HFC-134a refrigerant (R-134a).
11. Use only FD46XG compressor oil.
Attention: mixing oils intended for different air conditioning systems leads to compressor failure.
12. Use O-rings and glands designed for the type of refrigerant used only.
13. Be careful when tightening connections.
Apply some compressor oil to the rubber fitting seals to facilitate tightening and prevent refrigerant leaks.
14. Plug open hose ends and fittings immediately to prevent moisture and dust from entering.
15. If there is a refrigerant leak, ventilate the area before topping up the system.
