Atlas Copco Oil-Injected Rotary Screw Compressor GA 15

Refrigeration dryers of ID type contain refrigerant HFC

When handling refrigerant, all applicable safety precautions must be observed. Please be specifically aware of the following points

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;

CAUTION! Never use a high pressure water jet to clean the compressor

Stop the compressor, close the air outlet valve and switch off the voltage

Cover all parts under the coolers

Remove any dirt from the coolers with a fibre brush. Never use a wire brush or metal objects

Next, clean with an air jet in the reverse direction to normal flow. Use low pressure air. If necessary, the pressure may be increased up to 6 bar(e) (87 psig)

If it is necessary to wash the coolers with a cleaning agent, consult Atlas Copco;

WARNING! The operator must apply all relevant Safety precautions

Run the compressor until warm. Stop the compressor, close the air outlet valve and switch off the voltage. Wait a few minutes and depressurise by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape

Wait 5 minutes and remove the oil separator (OS). Clean the seat on the manifold. Oil the gasket of the new separator and screw it into place. Tighten firmly by hand
