NOTICE
1. To prevent distortion and breaking of the pipe, avoid sharp bends. Bend the pipe with a
radius of curvature of 6 in. (150 mm) or more.
2. If the pipe is bent repeatedly at the same place, it will break.
CAUTION
Be sure to connect the gas pipe after connecting the liquid pipe completely.
Connecting the Pipe at the Outdoor Units
Tighten the flare nut of the connection pipe at the outdoor unit valve connector. The tightening
method is the same as the method at the indoor unit.
Bending Pipes
1. The pipes should be shaped by your hands or a refrigerant pipe bending tool for tighter bends.
Be careful not to collapse them.
2. Do not bend the pipes in an angle more than 90°
3. When pipes are repeatedly bent or stretched, the material will be prone to damage, which may
lead to refrigerant leaks. Do not bend or stretch the pipes more than three times.
4. Do not bend the pipe while it is encased in the insulation. In this case, cut the insulation with a
sharp cutting tool as shown below, and bend it after exposing the pipe. After bending the pipe
as you want, be sure to put the insulation back on the pipe, and secure it with tape.
