Leveling
The water level test must be done after installing the indoor unit to make the unit is horizontal,as shown below.
Installation of the Connection Pipe
Flare Processing
1. Cut the connection pipe with the pipe cutter and remove the burrs.
2. Hold the pipe downward to prevent cuttings from entering the pipe.
3. Remove the flare nuts at the stop valve of the outdoor unit and inside the accessory bag of the indoor unit, then
insert them into the connection pipe. After that, flare the connection pipe with a flaring tool.
4. Check if the flared line is spread evenly and there are no cracks.
Bending Pipes
1. Shape the pipes with your hands. Be careful not to collapse or crush them.
2. Do not bend the pipes at an angle greater than 90°.
3. When pipes are repeatedly bent or stretched, the material will become hardened, making them difficult to bend or
stretch further. Do not have more than three bends in a pipe.
4. Do not bend pipe while covered in insulation. The pipe could kink or collapse. Instead, cut the heat insulation on
the pipe with a utility knife, as shown, and bend when the pipe is exposed. After bending the pipe to the desired
shape, replace the insulation on the pipe, and secure it with tape.
