Method and cautions on brazing the pipe
The use of Nitrogen gas
1. Use Nitrogen gas when brazing the pipes as shown in the picture.
2. If you don’t use Nitrogen gas when brazing the pipes, oxide may form
inside the pipe. It can cause the damage of the compressor and valves.
3. Adjust the flow rate of the nitrogen gas with a pressure regulator to
maintain 0.05m
3
/h(1.77 ft
3
/h) or less.
Direction of the pipe when brazing
• Performing the brazing of the pipe should be headed downwards or
horizontally.
Keeping refrigerant pipe clean and dry
X
To prevent foreign materials or water from entering the pipe, it is important to keep the refrigerant pipe clean, dry and sealed
during installation.
Brazing the pipe
X
Make sure that there is no moisture inside the pipe.
X
Make sure that there are no foreign materials and impurities in the pipe.
X
Make sure that there is no leak.
X
Make sure to follow the instruction when brazing the pipe.

Method and cautions on refrigerant pipe insulation
Make sure to check for gas leakage before completing the installation (hose and pipe insulation) and insulate hoses and pipes
when there is no sign of leakage.
1. To avoid condensation problems, place T13.0(1/2") or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
2. Wind insulating tape around the pipes and drain hose avoiding to compress
the insulation too much.
3. Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.
4. The pipes and electrical cables connecting the indoor unit with the outdoor
unit must be fixed to the wall with suitable ducts.
No gap
NBR(T13.0(1/2") or thicker)
• Always make the seam of pipes face upwards.
• All refrigerant connection must be accessible, in order to permit
either unit maintenance or removing it completely.
• Must fit tightly against
body without any gap.
