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.

The safety valve (SV) can be tested on a separate air line. If the valve does not open at the set pressure stamped on the valve, it needs to be replaced

An additional safety valve is fitted on tank mounted versions. The valve can be tested on a separate air line. If the valve does not open at the set pressure stamped on the valve, it needs to be replaced

WARNING! No adjustments are allowed. Never run the compressor without safety valve;

Warning: This procedure requires trained personnel with PPE!
