8.4 Maintenance operation on the refrigeration circuit
Maintenance and service on refrigerating systems must be carried out only by certified 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 environment.
This dryer comes ready to operate and filled with R134a or R407C type refrigerant fluid.
In case of refrigerant leak contact a certified refrigerating engineer. 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:
Refrigerant Chemical formula TLV GWP
R134a - HFC CH2FCF3 1000 ppm 1300
R407C - HFC
R32/125/134a (23/25/52)
