9.0 DRYER'S DISPOSAL

The equipment's disposal must be carried out according to the National Norms. These dryers contain cooling media HFC type and
lubrication oils that cannot be dispersed into the atmosphere.
Before scrapping the dryer, it's necessary to recover all the gas contained using specific gas cylinders and send them for recycle.
This operation must be done by qualified Personnel, who has all the proper equipment (consult our Service Centre for additional
