Lubrication

Lubrication

The lubricating oil is contained in the high pressure chamber (A).

When the compressor is operating the high pressure in the chamber pushes the oil through the calibrated hole (B) into the inner moving components.

The oil mixed with gas (C) is sent out through the reed valves (D) in the high pressure chamber.

A separator device (E) installed in the gas outlet union separates it from the oil (G) which falls by gravity into the bottom of the chamber (A) while the gas flows out of the union (F).

This device makes it possible to minimise the quantity of oil admitted into the system piping thereby increasing the thermal yield.

The compressor is also fitted with two safety valves (H) which relieve any overpressure in the compression chamber (I).

• A. High pressure chamber
• B. Calibrated hole
• C. Gas
• D. Reed valves
• E. Separator device
• F. Union
• G. Falling oil
• H. Safety valves
• I. Compression chamber

INSTRUCTIONS FOR REMOVING/REFITTING

During servicing operations, when the components of the air conditioner system are disconnected, plug the unions suitably to prevent damp and dirt from getting into the system.

When refitting the pipe unions always replace the O-Rings on them.
Lubricate the threads of the pipe unions with the specified antifreeze oil and tighten the unions to the specified torque.
In the event of any losses of oil from the system during servicing operations, restore the amount of oil in the system calculating the losses.
