SELECTING THE MOUNTING POSITION

Decide the mounting position together with the customer as follows:

INDOOR UNIT

(1)

Install the indoor unit on a place having a sufficient strength so that
it withstand against the weight of the indoor unit.

(2)

The inlet and outlet parts should not be obstructed; the air should
be able to blow all over the room.

(3)

Leave the space required to service the air conditioner (Fig. 1).

Fig. 1

150 mm
or more

Install the unit where the drain pipe can be easily installed.

(4)

Providing as much space as possible between the indoor unit and

(5)

the ceiling will make work much easier.

OUTDOOR UNIT

Install the unit where it will not be tilted by more than 5°.

(1)

When installing the outdoor unit where it may

(2)

exposed to strong wind, fasten it securely.

Leave the space indicated for good air flow. (Fig. 2)

(1)

Fig. 2

(2)

If possible, do not install the unit where it will exposed to direct sun­light. (If necessary, install a blind that does not interfere with the air
flow.)

(3)

Do not install the unit near a source of heat, steam, of flammable
gas.

(4)

During heating operation, drain water flows from the outdoor unit.
Therefore, install the outdoor unit in a place where the drain water
flow will not be obstructed. (Reverse cycle model only)

(5)

Do not install the unit where a strong wind blows or where it is very
dusty.

(6)

Do not install the unit where people pass.

(7)

Install the outdoor unit in a place where it will be free from being dir­ty or getting wet by rain as much as possible.

(8)

Install the unit when connection to the indoor unit is easy.

OUTDOOR UNIT INSTALLATION

1. OUTDOOR UNIT PROCESSING

(1)

When the outdoor unit will be exposed to strong wind, fasten it with
bolts or wire at the four places indicated by the arrows. (Fig. 12)

(2)

Since the drain water flows out of the outdoor unit during heating
operation, install the drain pipe and connect it to an commercial
16 mm hose. (When heating when the outdoor temperature is 0°C
or less, construct so that the drain water drained from the outdoor
unit will not freeze in the drain pipe.) (Reverse cycle model only)

(3)

When installing the drain pipe, plug all the holes other than the
drain pipe mounting hole in the bottom of the outdoor unit with put­ty so there is no water leakage. (Fig. 12) (Reverse cycle model only)

*

difficult inside the outdoor
unit, use the accessory
auxiliary pipe assembly.

CONNECTING THE PIPING

1. FLARE PROCESSING

(1)

Cut the connection pipe with pipe cutters so that the pipe is not
deformed.

(2)

Holding the pipe downward so that cuttings cannot enter the pipe,
remove the burrs.

(3)

Remove the flare nut from the indoor unit pipe and outdoor unit
and assemble as shown in (Table 3) and insert the flare nut onto
the pipe, and flare with a flaring tool.

(4)

Check if the flared part “L” (Fig. 17) is spread uniformly and that
there are no cracks.

2. BENDING PIPES

The pipes are shaped by your hands. Be careful not to collapse them.

Fig. 18

Do not bend the pipes in an angle less than 90°.
When the pipes are bent and stretched repeatedly, the material will be
hardened, causing the pipes no longer be sent or stretched. Be sure to
limit number of bending and stretchings to three times.

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 in Fig.
19, 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.

Fig. 19

3. CONNECTION PIPES

Indoor unit side

Detach the caps and plugs from the pipes.

CAUTION

Be sure to apply the pipe against the port on the indoor
unit correctly. If the centering is improper, the flare nut
cannot be tightened smoothly. If the flare nut is forced to
turn, the threads will be damaged.

CAUTION

Be sure to connect the large pipe after connecting the
small pipe completely.

Outdoor unit side

(1)

Tighten the flare nut of the connection pipe at the outdoor unit
valve connector. The tightening method is the same as that as at
the indoor side.

(2)

Seal with the accessory putty so that water does not enter at the
top of the pipe insulation installed to the connection pipe (large
pipe and small pipe).

CHECKING THE PIPE CONNECTIONS FOR GAS LEAKING

For both the indoor and outdoor unit sides, check the joints for gas
leaking by the use of a gas leakage detector without fail when the
pipes are connected.

•

connecting pipes.

•

lation (large) to the pipe at the two places shown below.

INSTALLING DRAIN HOSE

NOTE : INSTALL THE DRAIN HOSE

Install the drain hose so that there is a trap. The position of the

••

installed drain hose should have a downward gradient of (1/50 to
1/100). Make sure that the drain hose is installed without rises.
Make the trap near to the indoor unit.

•

Use general hard polyvinyl chloride pipe (VP25) [outside diameter

•

38 mm] and connect it with adhesive (polyvinyl chloride) so that
there is no leakage.
When the hose is long, install supporters.

•

Do not perform air bleeding.

•

Always heat insulate the indoor side of the drain hose.

ELECTRICAL WIRING

HOW TO CONNECT WIRING TO THE TERMINALS

A. For solid core wiring (or F-cable)

(1)

Cut the wire and with a wire cutter or wire-cutting pliers,
then strip the insulation to about 15/16” (25 mm) of 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

Cut the wire and with a wire cutter or wire-cutting pliers,

(1)

then strip the insulation to about 3/8” (10 mm) of expose
the strand wiring.
Using a screwdriver, remove the terminal screw(s) on the

(2)

terminal board.
Using a round terminal fastener or pliers, securely clamp a

(3)

round terminal to each stripped wire end.
Position the round terminal wire, and replace and tighten

(4)

the terminal screw with a screwdriver.

CAUTION

(1)

Tighten the indoor unit connection cord (to the out­door unit) and power supply indoor and outdoor unit
terminal board connections firmly with the terminal
board screws. Faulty connection may cause a fire.

(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
(Fig. 29).

(4)

Ground both the indoor and outdoor units by attach­ing a ground wire.

(5)

Unit shall be grounded in compliance with the appli­cable local and national codes.

Always use a special branch circuit and install a special

(3)

receptacle to supply power to the air conditioner.

Use a special branch circuit breaker and receptacle

(4)

matched to the capacity of the air conditioner.
(Install in accordance with standard.)

The special branch circuit breaker is installed in the per-

(5)

manent wiring.

Always use a circuit that can trip all the
poles of the wiring and has an isolation distance of at
least 3mm between the contacts of each pole.

Perform wiring work in accordance with standards so

(6)

that the air conditioner can be operated safely and
positively.

Install a leakage special branch circuit breaker in

(7)

accordance with the related laws and regulations
and electric company standards.

CAUTION

When the voltage is low and the air conditioner is diffi­cult to start, contact the power company the voltage
raised.
