Pipe bending
1. Perform bending of the pipe using the bender which has a specified
bending radius.
2. Be sure to take full care to perform bending of the pipe successfully at
one time. Bending and unbending the pipe more than twice makes the
bending work increasingly difficult.
3. You may use the spring inserted into the gas pipe instead of the bender to
bend the pipe.
4. When you bend the pipe using the spring, hold the pipe with both hands
to prevent any distortion, and secure a minimum bending radius of more
than 100mm.
Tightening of connection parts
f Align the pipes to be connected and tighten the flare nuts first manually
f
and then with a torque wrench, applying the following torque.
Outer diameter (mm)
ø 6.35
ø 15.88
f You can avoid of gas leakage by applying refrigerant oil on the flare
f
connection part.
Drilling a hole in the wall
f Drill a hole of 60mm in diameter to the outside.
f
f The drilling should be done at a distance of less than 150mm from the
f
floor facing the indoor unit.
❋ ❋ If a hole on the wall is above 150mm from the floor, use a hole for drain
hose (ø35mm) for connecting drain hose.
