INDOOR UNIT INSTALLATION

PREPARING INDOOR UNIT

INSTALLATION

You can use the accessory template to help you install the indoor
unit. The template helps you determine the appropriate locations for
suspension bolts and pipe openings (drain pipe and connection cord).

Fig. 6

1. LOCATION OF CEILING SUSPENSION BOLTS

Fig. 7

[For Half-Concealed Installation]

Suspension-bolt pitch should be as shown in Fig. 7.

Fig. 8

2. SELECT PIPING DIRECTION.

Select connection piping and drain piping directions (Fig.9).

Fig. 9

[For 4 Left rear piping, 5 Left piping]

Transfer the Drain cap and Drain cap seal.

Fig. 10

DRILLING THE HOLES AND ATTACHING THE SUS­PENSION BOLTS

Drill ø25mm holes at the suspension-bolt locations.
Install the bolts, then temporarily attach Special nuts A and B
and a normal M10 nut to each bolt. (The two special nuts are pro­vided with the unit. The M10 nut must be obtained locally.) Refer
to Fig. 11.

Fig. 11

[If using anchor bolts]

Drill holes for anchor bolts at the locations at which you will set
the suspension bolts. Note that anchor bolts are M10 bolts (to be
obtained locally).
Install the anchor bolts, then temporarily attach special nut "B"
(included) and a locally-procured M10 nut to each of the bolts.
(See Fig. 12.)

Fig. 12

4. INSTALLING THE INDOOR UNIT

Lift unit so that suspension bolts pass through the suspension fit­tings at the sides (four places), and slide the unit back. (See Fig.

14.)

Fig. 13

Fig. 14

Fasten the indoor unit into place by tightening-up the special “B”
bolts and the M10 nuts. Make sure that unit is secure and will not
shift back and forth.

[For Half-Concealed Installation]

When installing the indoor unit in a semi-concealed orientation, make
sure to reinforce the insulation of the unit on all sides. Drops of water
may fall from the unit if it is not thoroughly insulated.

Fig. 15

2. FLARE PROCESSING

Cut the connection pipe with pipe cutters so that the pipe is not
deformed.
Holding the pipe downward so that cuttings cannot enter the pipe,
remove the burrs.
Remove the flare nut from the indoor unit pipe and outdoor unit
and assemble as shown in (Table 4) and insert the flare nut onto
the pipe, and flare with a flaring tool.
Check if the flared part “L” (Fig. 19) is spread uniformly and that
there are no cracks.

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.)
Install the outdoor unit in a place where it will be free from being dir­ty or getting wet by rain as much as possible.
Install the unit when connection to the indoor unit is easy.
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. (Heat & Cool model (Reverse cycle) only)
Do not place animals and plants in the path of the warm air.
Take the air conditioner weight into account and select a place where
noise and vibration are small.
Select a place so that the warm air and noise from the air conditioner
do not disturb neighbors.

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.
21, 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.

GAS LEAKAGE INSPECTION

INSTALLING THE COUPLER HEAT

INSULATION

After checking for gas leaks, insulate by wrapping insulation around the
two parts (large and small) 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.
Secure both ends of the heat insulation material using nylon fasteners.

Fig. 29

When using an auxiliary pipe, make sure that the fastener
used is insulated in the same way.

DRAIN PIPING

Install the drain pipe with downward gradient (1/50 to 1/100) and so
there are no rises or traps in the pipe.
Use general hard polyvinyl chloride pipe (VP25) [outside diameter 38
mm].
During installation of the drain pipe, be careful to avoid applying
pressure to the drain port of the indoor unit.
When the pipe is long, install supporters (Fig. 30).
Do not perform air bleeding.
Always heat insulate (8mm or over thick) the indoor side of the drain
pipe.

Fig. 30

Install insulation for the drain pipe. (See Figs. 31 and 32.)
Cut the included insulation material to an appropriate size and
adhere it to the pipe.

HOW TO CONNECT WIRING TO THE TERMINALS

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

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.
Using a screwdriver, remove the terminal screw(s) on
the terminal board.
Using pliers, bend the solid wire to form a loop suitable
for the terminal screw.
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, 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 terminal board.
Using a round terminal fastener or pliers, securely
clamp a round terminal to each stripped wire end.
Position the round terminal wire, and replace and
tighten the terminal screw using a screwdriver.

AIR PURGE

1. AIR PURGE

Remove the cap, and connect the gauge manifold and the vacuum
pump to the charging valve by the service hoses.
Vacuum the indoor unit and the connecting pipes until the pres­sure in them lowers to below 1.5 mmHg.
Disconnect the service hoses and fit the cap to the charging valve
(Tightening torque : 70 to 90 kgf • cm).
Remove the blank caps, and fully open the spindles of the 2-way
and 3-way valves with a hexagon wrench (Torque : 2-way valve:
70 to 90 kgf • cm, 3-way valve: 100 to 120 kgf • cm).
Tighten the blank caps of the 2-way valve and 3-way valve to the
specified torque (200 to 250 kgf • cm).

2. ADDITIONAL CHARGE

Refrigerant suitable for a piping length of 5 m is charged in the outdoor
unit at the factory.
When the piping is longer than 5 m, additional charging is necessary.
For the additional amount, see the table below.

Between 5 m and 30 m, when using a connection pipe other than that in
the table, charge additional refrigerant with 1.8 oz (40 g) / 3.3 ft (1 m) (Re­verse cycle model), 0.6 oz (17 g) / 3.3 ft (1 m) (Cooling model) as the cri­teria.
