7.7 Maintenance instructions
Important
The dryers contain refrigerant HFC.
When the automatic operation LED is lit, starting and stopping of the dryer are controlled
automatically.
If the dryer start/stop timer is active, the dryer may start automatically, even if it was
stopped manually.
Safety precautions
When handling refrigerant R404A or R410A (refer to dryer data plate), all applicable safety
precautions must be observed. The following points are stressed:
•
Contact of refrigerant with the skin will cause freezing. Special gloves must be worn and, if
there is 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; therefore, safety glasses must be worn.
• Refrigerants R404A and R410A are poisonous. Do not inhale refrigerant vapors. Check that
the working area is adequately ventilated.
When removing the side panels of the dryer, be aware that internal elements such as the pipes
can reach a temperature of 120 ˚C (248 ˚F). Therefore, wait until the dryer has cooled down
before removing the side panels.
Before starting any maintenance or repairs, switch off the voltage. Isolate the dryer from the air
net.
Local legislation
Local legislation may impose that:
• Work on the refrigerant circuit of the cooling dryer or on any equipment which influences its
function must be carried out by an authorized control body.
• The installation should be checked once a year by an authorized control body.
Warranty and product liability
Use only authorized genuine parts. Any damage or malfunction caused by the use of
unauthorized parts is not covered by Warranty or Product Liability.
