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.
The compressor inlet temperature sensor cannot be removed when the dryer is
filled with refrigerant.
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 the dryer is filled with refrigerant, it is forbidden to remove the refrigerant compressor
inlet sensor.
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 outlet collector (6).
