Atlas Copco Rotary Screw Air Compressor GA22VSD

NOTE! If Atlas Copco Roto-Inject Fluid is used, change oil and oil filter

WARNING! The operator must apply all relevant Safety precautions

Always drain the compressor oil at all drain points

Used oil left in the compressor can contaminate the oil system and can shorten the lifetime of the new oil

Never mix lubricants of different brands or types as they may not be compatible and the oil mix will have inferior properties

A label, indicating the type of oil filled ex-factory, is stuck on the air receiver/oil tank

Run the compressor until warm, close the air outlet valve and let the compressor run for 3 minutes at minimum speed

Stop the compressor, press the emergency stop button, open manual drain valve(s) (Dm, Dm1) and wait until the compressor has depressurized

Unscrew oil filler plug (FC) only one turn to permit any pressure in the system to escape

Check coolers, clean if necessary

Safety precautions: Refrigeration dryers of ID type contain refrigerant HFC. When handling refrigerant, all applicable safety precautions must be observed.

Contact of refrigerant with the skin will cause freezing. Special gloves must be worn. If contacted with the skin, the skin should be rinsed with water. On no account may clothing be removed.

Fluid refrigerant will also cause freezing of the eyes; always wear safety glasses.

Refrigerant is harmful. Do not inhale refrigerant vapours. Check that the working area is adequately ventilated.

Be aware that certain components such as the refrigerant compressor and the discharge pipe can become quite hot (up to 110 °C - 230 °F). Therefore, wait until the dryer has cooled down before removing the panels.

Before starting any maintenance or repair work, switch off the voltage and close the air inlet and outlet valves.

Local legislation may stipulate that work on the refrigerant circuit of the cooling dryer or on any equipment which influences its function must be undertaken by an authorised control body.

The installation should be checked once a year by an authorised control body.
