Refrigerant Oil
The special refrigerant oil (for use with refrigerant circuits R134a only) is not commercially available .
Refrigerant R134a and refrigerant oil, refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS .
-- Discharging, evacuating and recharging refrigerant circuit, refer to HEATING, VENTILATION & AIR CONDITIONING (1 OF 2) or/and HEATING, VENTILATION & AIR CONDITIONING (2 OF 2) .
-- Operate the Air Conditioning (A/C) system after filling the refrigerant circuit, refer to A/C SYSTEM, STARTING OPERATION AFTER FILLING REFRIGERANT CIRCUIT (Refrigerant R134a, Servicing; A/C System, General Information). After charging the A/C system before activating the A/C system.
Malfunctions due to filling the A/C system with the wrong refrigerant oil.
- Only fill the refrigerant circuit with approved refrigerant oils . The correct refrigerant oil depends on the manufacturer and the type of A/C compressor installed, refer to HEATING, VENTILATION & AIR CONDITIONING (1 OF 2) or/and HEATING, VENTILATION & AIR CONDITIONING (2 OF 2) .
Malfunctions due to improper filling of the A/C system with refrigerant oil.
- Too much refrigerant oil in the refrigerant circuit increases the pressures and reduces the cooling output of the system.
- Too little refrigerant oil in the refrigerant circuit can lead to the A/C compressor failure due to lubrication problems.
Danger of corrosion in the refrigerant circuit.
- Refrigerant oil absorbs moisture. Do not use refrigerant oil from containers that have been left open for a lengthy period of time, refer to HEATING, VENTILATION & AIR CONDITIONING (1 OF 2) or/and HEATING, VENTILATION & AIR CONDITIONING (2 OF 2) .
Important information
Refrigerant oil attracts moisture. Close any opened containers immediately after use to prevent moisture from entering.
