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).

• 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.

covered by Warranty or Product Liability.
