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.

Check if the working area is adequately ventilated.

Check if the dryer has cooled down before removing the panels.

Check that condensate is discharged during loaded operation

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
