6 Maintenance
6.1 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 R410A, 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.
• Refrigerant R410a is 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 and depressurize by opening valve (5) on inlet collector (6).
