Installation

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 conve-

niently routed away.

4. Do not install near a doorway.

5. Ensure that the interval between a wall and the left

(or right) of the unit is more than 50cm. The unit

should be installed as high as possible on the wall,

allowing a minimum of 10cm from ceiling.

6. Use a stud finder to locate studs to prevent unneces-

sary 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 radia-

tion from the condenser is not restricted.

2. Ensure that the space around the back and sides is

more than 10cm. The front of the unit should have

more than 70cm of space.

3. Do not place animals and plants in the path of the

warm air.

4. Take the weight of the air conditioner into account

and select a place where noise and vibration are min-

imum.

5. Select a place where the warm air and noise from the

air conditioner do not disturb neighbors.

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

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 out-

door unit.

3. Cut the pipes a little longer than measured distance.

4. Cut the cable 1.5m 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 drop-

ping 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

1. Firmly hold copper pipe in a die in the dimension shown

in the table below.

2. Carry out flaring work with the flaring tool.

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 the plastic tubing holder in the original posi-

tion.(Optional)

1. Route the indoor tubing and the drain hose in the

direction of rear right.

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 connec-

tion 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.

CAUTION: 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 fur-

niture or floors.

*Foamed polyethylene or equivalent is recom-

mended.

4. Indoor unit installation

Hook the indoor unit onto the upper portion of the

installation plate.(Engage the two hooks of the rear

top of the indoor unit with the upper edge of the

installation plate.) Ensure that the hooks are properly

seated on the installation plate by moving it left and

right.

Press the lower left and right sides of the unit against

the installation plate until the hooks engage into their

slots(clicking sound).

Connecting the piping to the indoor unit and drain

hose to drain pipe.

1. Align the center of the pipes and sufficiently tighten

the flare nut by hand.

2. Tighten the flare nut with a wrench.

3. When extending the drain hose at the indoor unit,

install the drain pipe.

Wrap the insulation material around the connecting

portion.

1. Overlap the connection pipe insulation material and

the indoor unit pipe insulation material. Bind them

together with vinyl tape so that there may be no gap.

2. Wrap the area which accommodates the rear piping

housing section with vinyl tape.

3. Bundle the piping and drain hose together by wrap-

ping them with vinyl tape for enough to cover where

they fit into the rear piping housing section.
