4.3.3. Pipe connection
When the fl are nut is tightened properly by your hand, hold the body side coupling with a
separate spanner, then tighten with a torque wrench.
Hold the torque wrench at its grip, keeping it at a right angle with the pipe, in order to
tighten the fl are nut correctly.

Indoor unit pipe
(Body side)
Be sure to install the pipe against the port on the indoor unit and the outdoor unit
correctly. If the centering is improper, the fl are nut cannot tightened smoothly. If the
fl are nut is forced to turn, the threads will be damaged.
Do not remove the flare nut from the indoor unit pipe until immediately before
connecting the connection pipe.
Do not use mineral oil on fl ared part. Prevent mineral oil from getting into the system
as this would reduce the lifetime of the units.

5. INSTALLING DRAIN PIPES
• Use general hard polyvinyl chloride pipe (VP25) and connect it with adhesive (polyvinyl
chloride) so that there is no leakage.
• The position of the installed drain pipe should have a downward gradient of 1/100 or
more.
• To prevent the pipe from freezing, use a heat insulation material as needed.

• For safety drain port
• This product has drain ports in 2 locations. Follow the procedure in the fi gure to connect
drain hose and drain pipes to each of them.
Install the drain hose to the main and safety drain port
Working procedure
(1) Install the attached drain hose to the main and safety drain port of the body. Install
the hose band from the top of the hose within the graphic display area. Secure fi rmly
with the hose band.
(2) Use vinyl adhesive agent to glue the drain piping (PVC pipe VP25) which is prepared
on site or piping socket. (Apply color adhesive agent evenly until the gauge line and
seal)
(3) Check the drainage.
(4) Install the heat insulation.
(5) Use the attached heat insulation to insulate the drain port and band parts of the body.
