6 Maintenance instructions
Attention
Cooling dryers of QED type contain refrigerant HFC.
Safety precautions
When handling refrigerant, all applicable safety precautions must be observed. Please be aware of the
following points:
• Contact of refrigerant with the skin will cause freezing. Special gloves must be worn. In case of contact
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; safety glasses must hence be worn.
• Refrigerant is harmful. Do not inhale refrigerant vapours. Check that the working area is adequately
ventilated.
When removing the service panels of the dryer, be aware that internal elements such as the pipes can reach a
temperature of 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.
Mind the sharp edges of the fan blades in case the condenser fan needs to be replaced. The use of hand
protection is a requisite.
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
The following remarks should be kept in mind:
• Keep the dryer clean.
• The dryer is equipped with a new condenser technology, which provides the best efficiency on condition
that the condenser maintenance instructions are followed closely.
