■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

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 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

Installation of Indoor, Outdoor Unit

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 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.
