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.

WARNING! Always 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.

If the compressor is equipped with an Energy Recovery unit, also drain the oil in the heat exchanger.

Run the compressor until warm. Stop the compressor. Close the air outlet valve and switch off the voltage.

Depressurize the compressor by opening the manual drain valve(s). Wait a few minutes and depressurize the air receiver/oil tank by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape.

Open the filler plug (FC) and drain the oil by opening the valve at the bottom of the oil tank (OT).

Also remove the drain plug near the element outlet. Close the drain valve and fit the plugs after draining.

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
