13. R4073 R4074 A Caution Be careful about four way valve pipes and so on which were heated up by a gas brazing machine so as not to get burnt on your hands Cautions at the restoration 1 Restore the piping by non oxidation brazing Braze it quickly unless nitrogen gas can be used 2 Itis required to prevent the carbonization of the oil inside the four way valve and the deterioration of the gaskets affected by heat For the sake of this wrap the four way valve with wet cloth and make up water so that the cloth will not be dried and avoid excessive heating It keeps below 120 C Be careful so as not to break pipes by pressing the pipes excessively by pliers when withdrawing the piping 212 Removal Procedure SiENBE04 401A Outdoor Unit RK X H C ARK X H C R Y N C Step Procedure Points R4075 R4076 In case that the removal seems to be hard 1 Remove the piping connection part brazing part which is easy to remove and restore 2 Cut the pipes on the main unit by a miniature copper tube cutter in order to make it easy to remove NOTE Don t use a metal saw for cutting pipes by all means because the chips come into the circuit Cautions at the restoration Wrap the motor valve with wet cloth and make up water so that the cloth will not be dried and avoid excessive heating
