(Gas piping connection) While the main gas side pipe is ø25.4, since connecting the outdoor unit's 3-way valve requires a ø19.05
fl are, please be sure to use standard accessories joint piping B or A for connection (brazing), and connect as follows.
1. Since standard accessory joint piping B comes supplied for connecting the outdoor unit's 3-way valve, machine the upper
edge to ø19.05 flare specifi cations.
2. Refer to connection pipe process examples (1) - (4) to cut the joint piping A to the necessary length.
3. Braze the machined (cut) joint piping A to the bottom edge of joint piping B.
4. In order to protect wiring and parts in the unit, please carry out brazing outside the unit (since each type of joint piping is
differently oriented, carry out brazing according to the orientations shown in the connection pipe process diagrams.
5. Connect the brazed connection pipes to the outdoor unit's 3-way valve through the fl are connection.
When cutting the pipe, use a pipe cutter and be sure to carry out deburring.
Ensure that water, sand etc. do not enter the interior of the piping.
Using a fl are tool, carry out sound fl are process.
When installing multiple units, allow enough space in between the
