Installation

Read completely, then follow step by step.

1. Installation of Indoor, Outdoor unit

1) Select the best location

1. Indoor unit

■ Do not have any heat or steam near the unit.

■ Select a place where there are no obstacles in

front of the unit.

■ Make sure that condensation drainage can be

conveniently routed away.

■ Do not install near a doorway.

■ Ensure that the space around the left and right of

the unit is more than 5cm. The unit should be

installed as high on the wall as possible, allowing

a minimum of 5cm from ceiling.

■ Use a stud finder to locate studs to prevent

unnecessary damage to the wall.

2. Outdoor unit

■ 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.

■ 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.

■ 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 mini-

mum.

■ Select a place so that the warm air and noise

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.

2) Piping length and elevation

• Capacity is based on standard length and maximum

allowance length is on the basis of reliability.

• Oil trap should be installed every 5~7 meters.

3) How to fix installation plate

The wall you select should be strong and solid enough to prevent

vibration

1. Mount the installation plate on the wall with four

type A screws. If mounting the unit on a concrete

wall, use anchor bolts.

§ Mount the installation plate horizontally by align-

ing 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 con-

nections must be done safely.

4) Drill a hole in the wall

■ Drill the piping hole with a ø70mm hole core drill.

Drill the piping hole at either the right or the left

with the hole slightly slanted to the outdoor side.

1) Flaring work

Main cause for gas leakage is due to defect in flar-

ing work. Carry out correct flaring work in the follow-

ing procedure.

1. Cut the pipes and the cable.

■ Use the piping kit accessory or the pipes pur-

chased locally.

■ Measure the distance between the indoor and the

outdoor unit.

■ Cut the pipes a little longer than measured dis-

tance.

■ Cut the cable 1.5m longer than the pipe length.

2. Burrs removal

■ Completely remove all burrs from the cut cross

section of pipe/tube.

■ Put the end of the copper tube/pipe in a down-

ward direction as you remove burrs in order to

avoid dropping burrs into the tubing.

3. Putting nut on

■ Remove flare nuts attached to indoor and outdoor

unit, then put them on pipe/tube having complet-

ed burr removal.

(not possible to put them on after flaring work)

4. 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.

5. Check

■ Compare the flared work with figure below.

■ If flare is noted to be defective, cut off the flared

section and do flaring work again.

2. Flaring Work and Connection of Piping

- 26 -

2) Connection of piping-Indoor

■ Preparing the indoor unit's piping and drain hose

for installation through the wall.

■ Remove the plastic tubing retainer(see illustra-

tion below) and pull the tubing and drain hose

away from chassis.

■ Replace the plastic tubing holder in the original

position.

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

direction of rear left.

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 con-

nection later.

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 mov-

ing 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).

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 upper

side can cause drain pan to overflow inside the

unit.

5. Connecting the pipings to the indoor unit and

drain hose to drain pipe.

■ Align the center of the pipings and sufficiently

tighten the flare nut by hand.

NOTE:

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.

To remove the holder,

press the bottom of

chassis near the holder

upward and pull the tab

out of its hole.
