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