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.
General
For all references see section Introduction.
The following remarks should be kept in mind:
• Keep the dryer clean.
• Brush or blow off the finned surface of condenser monthly.
• Inspect and clean the electronic condensate drain monthly.
