❈ When the pipe length is in excess of the standard pipe length of 5m, add the refrigerant (R22) of
70g for each additional 1m.
3. Install the high pressure pipe to the heat exchanger liquid pipe, and the low pressure pipe to the
heat exchanger gas pipe respectively using the flare nut, taking care not to cause any leakage of refrigerant.
4. Be sure to insulate the pipe with appropriate insulation material.
5. Insert the drain hose into the drain pipe, and connect them by tying them to the cable tie to prevent
any water leakage.
6. After completion of the installation, check the connecting area for any gas leakage.

❏ 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
◆ Align the center of the connection piping, and tighten the flare nut
by turning it with hand. Then tighten it again using the spanner in
the direction as shown in the figure.

200mm from the floor facing the indoor unit.
◆ Extend the drain hose to the drain hose connected to
the drain pan, and fix it with the tape or a cable-tie to
prevent separation. Then make a covering of it so
that water cannot flow outwardly.
CAUTION
1. As the draining is of natural drain type, make the drain hose direct
downward.
2. If there is any foreign substance in the drain plate, it may clog the
drain pipe. Therefore, be sure to remove the foreign substance
inside after installation.
3. After completion of installation, be sure to pour water into the drain
pan, and then check the draining condition.
(There is no problem in draining when the draining is completed
