Installation Manual 9
Installation of Indoor, Outdoor Unit
Read completely, then follow step by step.
Indoor unit
1. Do not have any heat or steam near the unit.
2. Select a place where there are no obstacles
in front of the unit.
3. Make sure that condensation drainage can be
conveniently routed away.
4. Do not install near a doorway.
5. Ensure the spaces indicated by arrows from
the wall, ceiling, fence or other obstacles.
6. Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
Outdoor unit
1. If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
2. Ensure that the spaces indicated by arrows
around front, back and side of the unit.
3. Do not place animals and plants in the path
of the warm air.
4.Take the air conditioner weight into account
and select a place where noise and vibration
are minimum.
5.
Select a place so that the warm air and sound
from the air conditioner do not disturb
neighbors.
Rooftop Installations:
If the outdoor unit is installed on a roof
structure, be sure to level the unit. Ensure the
roof structure and anchoring method are
adequate for the unit location. Consult local
codes regarding rooftop mounting.

The wall you select should be strong and solid
enough to prevent vibration
1. Mount the installation plate on the wall with
type "A" screws. If mounting the unit on a
concrete wall, use anchor bolts.
•Mount the installation plate horizontally by
aligning the centerline using a level.
2. Measure the wall and mark the centerline. It
is also important to use caution concerning
the location of the installation plate-routing
of the wiring to power outlets is through the
walls typically. Drilling the hole through the
wall for piping connections must be done
safely.

Flaring Work and Connection of Piping
Flaring work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the
following procedure.
Cut the pipes and the cable.
1. Use the piping kit accessory or the pipes
purchased locally.
2. Measure the distance between the indoor and
the outdoor unit.
3. Cut the pipes a little longer than measured
distance.
4. Cut the cable 1.5m (5.0ft) longer than the pipe
length.
Burrs removal
1. Completely remove all burrs from the cut cross
section of pipe/tube.
2. Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.
Putting nut on
•Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube having
completed burr removal.
(not possible to put them on after flaring work)
Flaring work
•Carry out flaring work using flaring tool as shown
below.
•Firmly hold copper pipe in a die in the dimension
shown in the table above.

Check
1. Compare the flared work with the figure by.
2. If a flared section is defective, cut it off and
do flaring work again.
Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2. Remove the plastic tubing retainer(see the
illustration by) and pull the tubing and drain
hose away from chassis.
3. Replace only the plastic tubing holder 1, not
the holder 2 in the original position.
1. Route the indoor tubing and the drain hose in
the direction of rear right.
2.
Insert the connecting cable into the indoor unit
from the outdoor unit through the piping hole.
•Do not connect the cable to the indoor unit.
•Make a small loop with the cable for easy
connection later.
3.Tape the tubing, drain hose, and the
connecting cable. Be sure that the drain hose
is located at the lowest side of the bundle.
Locating at the uper side can cause drain pan
to overflow inside the unit.
If the drain hose is routed inside the room,
insulate the hose with an insulation material*
so that dripping from "sweating"(condensation)
will not damage furniture or floors.
*Foamed polyethylene or equivalent is
recommended.

Installation Manual 19
Connecting the Cable between Indoor Unit and Outdoor Unit
Connect the cable to the indoor unit by connecting the wires to the terminals on the control
board individually according to the outdoor unit connection. (Ensure that the color of the wires
of the outdoor unit and the terminal No. are the same as those of the indoor unit.)
The earth wire should be longer than the common wires.
The circuit diagram is not subject to change without notice.
When installing, refer to the electrical diagram behind the front panel of Indoor Unit.
The wiring for the outdoor unit can be found on the inside of the Outdoor Unit control cover.
Connect the cable to the Indoor unit.
WARNING:
• The circuit diagram is not subject to change without notice.
• Be sure to connect wires according to the wiring diagram.
• Connect the wires firmly, so that not to be pulled out easily.
• Connect the wires according to color codes by referring to the wiring diagram.
WARNING: Provide a circuit
breaker between power source
and the outdoor unit as shown
below.
WARNING! :The power wire to the outdoor unit must be of sufficient gauge
to meet the Minimum Circuit Ampacity (MCA) as indicated on the outdoor
unit rating plate and be of type required by NEC and local codes.
The connecting cable between the indoor and outdoor unit should be SJOW
type, minimum 18 gauge, and meet requirements of NEC and local codes.
