Safety precautions
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.
Local legislation
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.
