Introduction

Reuse of existing piping

Before replacement

After replacement

* It is possible to keep R-22 indoor units from K-series and later version It is not possible to combine old R-22 and new R-410A indoor units in one

system due to incompatibility of communication.

* For reuse of existing refrigerant piping ,it is possible to use piping or branched piping capable of handing 3.3 Pa or more .Heat insulation is

necessary for liquid piping and gas piping.

Replace
