Dryer Cartridge

• See notes, refer to => [ Refrigerant Circuit System Overview ] Refrigerant Circuit System Overview.

• Refrigerant must be extracted before hand using ROB 134APF.

• The previously used service stations can still be used. Refer to workshop equipment catalog.

• To prevent the entry of dampness all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.

- Extract refrigerant using ROB 134APF , only then open the refrigerant circuit.

Removing
