You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may
follow the installation method mentioned below.
When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque
suddenly increases. From that position, further tighten the flare nut the angle shown below:
Precautions when brazing piping
Be sure to perform a nitrogen blow when brazing.
(Brazing without carrying out nitrogen replacement or releasing nitrogen into the piping will create large
quantities
of oxidized film on the inside of the pipes, adversely affecting valves and compressors in the
refrigerating
system and preventing normal operation.)
• See the Installation manual (available at Daikin dealers) for details on how to perform nitrogen replacement.
• When feeding nitrogen into the pipes while doing the brazing, the letdown valve should be set to 0.02M
Pa
(i.e. it should feel like a slight breeze if blown on your cheek).
CAUTION
Do not use anti-oxidants when brazing the pipe joints. (Residue can clog pipes and break equipment.)
7. EVACUATING
• Perform a refrigerant leak check using nitrogen gas (airtightness test) with the outdoor unit stop valves
close, to make sure there are no leaks.
For the airtightness test, raise the pressure to the design pressure in the high pressure section. (4.0 MPa)
• Do not forget to perform an air purge of the refrigerant system using a vacuum pump.
NOTE
• After doing an air-purge with a vacuum pump, the refrigerant pressure may not rise even if the stop valve
is opened. This is because the refrigerant piping path is closed off by the outdoor unit electronic expansion
valve, etc.
There are no problems if the unit is run.
