Use caulking, putty, or a similar material to fill any gaps
at the refrigerant tube port ( ) in order to prevent
rainwater, dust or foreign substances from entering the
unit.
* Perform this work even if the tubing is routed out in a
downward direction.
Tighten each cap as specified below.
Service port cap
(width 15 mm)
7 – 12 N · m (70 – 120 kgf · cm)
Valve cap
(width 22 mm)
20 – 25 N · m (200 – 250 kgf · cm)
Flare nut
(valve dia. ø9.52)
34 – 42 N · m (340 – 420 kgf · cm)
Precautions for brazing
Be sure to replace the air inside the tube with nitrogen
to prevent oxide film from forming during the brazing
process.
Be sure to use a damp cloth or other means to cool the
valve unit during brazing.
1.
2. Use a pressure-reducing valve on the nitrogen tank.
3. Do not use agents intended to prevent the formation of
oxide film. They will adversely affect the refrigeration
oil, and may cause equipment failure.
4. The balance tube is not used if only 1 outdoor unit is
installed.
Use the unit in the same conditions as when it was
shipped from the factory.
