CAUTION
CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING
•
“Do not use fl ux when brazing refrigerant piping. Therefore, use the phosphor copper brazing fi lter metal
(BCuP) which does not require fl ux.”
(Flux has an extremely negative effect on refrigerant piping systems. For instance, if chlorine based fl ux
is used, it will cause pipe corrosion. If the fl ux contains fl uorine, it will damage the refrigerant oil.)
When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution
•
(NOTE 1) or while inserting nitrogen into the refrigerant piping (NOTE 2). Once this is done, connect the
indoor unit with a fl ared or a fl anged connection.
DANGER
Use of oxygen may cause an explosion resulting in serious injury or death. Only use nitrogen gas.
•
NOTE
Refer to the “Manual for Multi Installation for Buildings” for directions on how to carry out nitrogen
1.
substitution. (Inquire with your dealer.)
Nitrogen should be set to 2.9 psi with a pressure-reducing valve if brazing while inserting nitrogen into
2.
the piping.

After checking for gas leaks, be sure to insulate the pipe connections using the supplementary piping
•
insulation tubing and insulating tape (4). The insulating tape (4) should be wrapped from the L-shaped
bend all the way to the end inside the unit.
