6.3 MAINTENANCE OPERATION ON THE REFRIGERATING CIRCUIT
Maintenance and service on refrigerating
refrigerating engineers only, according to local rules.
All the refrigerant of the system must be recovered for its recycling, reclamation or destruction.
DO NOT DISPOSE THE REFRIGERANT FLUID IN THE ENVIROMENT.
This dryer comes ready to operate and filled with R134a or R404A type refrigerant fluid.
In case of refrigerant leak contact a certified refrigerating engineers. Room is to be aired before
any intervention.
If is required to re-fill the refrigerating circuit, contact a certified refrigerating engineers.
Refer to the dryer nameplate for refrigerant type and quantity.
Characteristics of refrigerants used:

We recommend to comply with the safety rules in force for the disposal of each type of material.
The chilling fluid contains droplets of lubrication oil released by the refrigerating compressor.
Do not dispose this fluid in the environment. Is has to be discharged from the dryer with a suitable
device and then delivered to a collection centre where it will be processed to make it reusable.
