• 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.
