CAUTION
Do not bundle the remote controller cord, or wire
the remote controller cord in parallel, with the
indoor unit connection wire (to the outdoor unit)
and the power supply cord. It may cause errone-
ous operation.
3. CONNECTION PIPES
Indoor unit
(1) Detach the caps and plugs from the pipes.
CAUTION
1
To prevent breaking of the pipe, avoid sharp
bends.
Bend the pipe with a radius of curvature of 150
mm or over.
2
If the pipe is bent repeatedly at the same place,
it will break.
CAUTION
1
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.
2
While welding the pipes, be sure to blow dry
nitrogen gas through them.

CONNECTING THE
PIPE
When bending the pipe, do not
bend it as is. The pipe will be
collapsed. In this case, cut the
heat insulating pipe with a sharp
cutter as shown on the right, and
bend it after exposing the pipe.
After bending the pipe as you
want, be sure to put the heat
insulating pipe back on the pipe,
and secure it with tape.

2. BENDING PIPES
The pipes are shaped by your hands. Be careful not to collapse
them.
Extend the pipe
by unwinding it
Do not bend the pipes in an angle more than 90°.
When pipes are repeatedly bent or stretched , the material will
harden, making it dif
fi
cult to bend or stretch them any more. Do
not bend or stretch the pipes more than three times.
(1) Remove the control box cover and install each connection
wire.

After checking for gas leaks, insulate by wrapping insulation
around the two parts (gas and liquid) of the indoor unit coupling,
using the coupler heat insulation.
After installing the coupler heat insulation, wrap both ends with
vinyl tape so that there is no gap.

The air

ow is set according to the DIP switch settings in the
following tables.
1. FLARING
(1) Cut the connection pipe to the necessary length with a pipe
cutter.
(2) Hold the pipe downward so that cuttings will not enter the pipe
and remove the burrs.
(3) Insert the
fl
are nut (always use the
fl
are nut attached to the
indoor and outdoor units respectively) onto the pipe and
perform the
fl
are processing with a
fl
are tool.
Use the special R410A
fl
are tool, or the conventional
fl
are
tool.
Check if [L] is flared uniformly
and is not cracked or scratched

CAUTION
1
Be sure to apply the pipe against the port on the
indoor 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.
2
Do not remove the
fl
are nut from the indoor unit
pipe until immediately before connecting the
connection pipe.
(2) Centering the pipe against port on the indoor unit, turn the
fl
are nut with your hand.
To prevent gas leakage, coat the flare
surface with alkylbenzene oil (HAB).
Do not use mineral oil.
When the
fl
are nut is tightened properly by your hand, use a torque
wrench to
fi
nally tighten it.

HOW TO CONNECT WIRING TO THE
TERMINALS
A. For solid core wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers,
then strip the insulation to about 25 mm (15/16”) to expose
the solid wire.
(2) Using a screwdriver, remove the terminal screw(s) on the
terminal board.
(3) Using pliers, bend the solid wire to form a loop suitable for
the terminal screw.
(4) Shape the loop wire properly, place it on the terminal
board and tighten securely with the terminal screw using
a screwdriver.
B. For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers,
then strip the insulation to about 10 mm (3/8”) to expose
the strand wiring.
(2) Using a screwdriver, remove the terminal screw(s) on the
terminal board.
(3) Using a round terminal fastener or pliers, securely clamp
a round terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten
the terminal screw using a screwdriver.
WARNING
1
Before starting work, check that power is not
being supplied to the indoor unit and outdoor
unit.
2
Match the terminal board numbers and con-
nection cord colors with those of the outdoor
unit.
Erroneous wiring may cause burning of the
electric parts.
3
Connect the connection cords firmly to the
terminal board. Imperfect installation may
cause a
fi
re.
4
Always fasten the outside covering of the
connection cord with the cord clamp. (If the
insulator is chafed, electric leakage may occur.)
5
Always connect the ground wire.
6
Install the remote controller wires so as not to
be direct touched with your hand.
(3) Install control box cover.
Adjust the position of the screws for control box cover according
to the installation.

CAUTION
1
Tighten the indoor unit connection cord (to the

re.
2
If the indoor unit connection cord (to the outdoor
unit) and power supply are wired incorrectly, the
air conditioner may be damaged.
3
Wire the indoor unit connection cord (to the
outdoor unit) by matching the numbers of
the outdoor and indoor units terminal board
numbers as shown in terminal label.
4
Ground both the indoor and outdoor units by
attaching a ground wire.
