• 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.
