When using conventional (R22) fl are tools to fl are R410A pipes, the dimension A should
be approximately 0.02 in. (0.5 mm) more than indicated in the table (for fl aring with R410A
fl are tools) to achieve the specifi ed fl aring. Use a thickness gauge to measure the dimen-
sion A. It is recommended that a R410A fl aring tool is used.

4.3.2. Bending pipes
•
The pipes are shaped by your hands or pipe bender. Be careful not to collapse them.
•
Do not bend the pipes in an angle more than 90°.
•
When pipes are repeatedly bend or stretched, the material will harden, making it diffi cult
to bend or stretch them any more. Do not bend or stretch the pipes more than 3 times.
To prevent breaking of the pipe, avoid sharp bends.
If the pipe is bent repeatedly at the same place, it will break.
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 in the right angle with the pipe, in order to
tighten the fl are nut correctly.
Tighten the fl are nuts with a torque wrench using the specifi ed tightening method.
Otherwise, the fl are nuts could break after a prolonged period, causing refrigerant to
leak and generate hazardous gas if the refrigerant comes into contact with a fl ame.

(Body side)
Be sure to apply the pipe against the port on the indoor unit and the outdoor unit
correctly. If the centering is improper, the fl are nut cannot be 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.

4.4. Installing heat insulation
0 (0)
-0.015 (-0.4)
Install the coupler heat insulation after completing the refrigerant leak check (for details,
refer to the Installation Manual for the outdoor unit).
There should be no gaps between the insulation and the product.
5. INSTALLING DRAIN PIPES
• Use general hard polyvinyl chloride pipe ø 3/4 in. [I.D.], ø 1-1/16 in. [O.D.] 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) [Φ 3/4 in. (19 mm) I.D.
Φ 1-1/16 in. (27 mm) O.D.] 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.
