Maintenance and repair works at refrigeration systems must only be carried out by certified refrigerating
engineers only in accordance with the local provisions.
The total amount of refrigerant in the system must be collected for recycling purposes, resource recovery
or disposal.
The refrigerant must not be discharged into the environment.
When delivered, the dryer is ready to operate and filled with a refrigerant of the R134a or R407C type.
Should you detect a refrigerant leak, please contact a certified refrigerating engineer. Prior to any
intervention, the room needs to be ventilated.
When the refrigeration cycle needs to be refilled, please also contact a certified refrigerating engineer.
