8-15 Heat exchanger Replacement Instructions
The heat exchanger of this model uses aluminum pipes.
When replacing the heat exchanger, be sure to remove it at the copper pipe brazed part (A).
Do not perform the replacement work at the joint part (C) of the copper pipe and aluminum pipe or at the aluminum pipe part
(B).
Before performing the brazing work, consider measures to prevent the temperature of the joint part (C) from rising such as
covering the entire joint with a cloth that is sufficiently wet.
Before beginning the replacement work, also give sufficient consideration to preventing the flame contacting the aluminum
part during brazing because aluminum melts at a lower temperature than copper.
