• Do not cool excessively indoors. This may be harmful for your health and may consume more

electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air

conditioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the

air flow or weaken the cooling / dehumidifying functions.

ENGLISH

Select the best Location

- There should not be any heat or steam near

the unit.

- Select a place where there are no obstacles

around the unit.

- Make sure that condensation drainage can

be conveniently routed away.

- Do not install near a doorway.

- Ensure that the gap between a wall and the

left (or right) of the unit is more than 4in. The

unit should be installed as high as possible

on the wall, allowing a minimum of 8in from

ceiling.

- Use a metal detector to locate studs to pre-

vent unnecessary damage to the wall.

* Recommended height 6.5ft from the floor.

* The feature can be changed according to the

type of model.

- 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 side

and other sides is more than 12in. The space

in front of the unit should be more than 28in.

- Do not place animals and plants in the path

of the warm air.

- Take the weight of the air conditioner into

account and select a place where noise and

vibration are minimum.

- Select a place where the warm air and noise

from the air conditioner do not disturb neigh-

bors.

Drill a Hole in the Wall

- Drill the piping hole with a ø65mm hole core

drill. Drill the piping hole at either the right or

the left with the hole slightly slanted to the

outdoor side.

Flaring Work

Main cause for gas leakage is due to defect of

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.

Fixing Installation Plate

The wall you select should be strong and solid

enough to prevent vibration.

1 Before installation, confirm the position of a

screw between chassis and Installation

plate.

2 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 Horizontal

meter .

3 Measure the wall and mark the centerline.

It is also important to use caution concern-

ing 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.

wires of the outdoor unit and the terminal No.

are the same as those of the indoor unit.)

CAUTION

- The circuit diagram is a subject to

change without notice.

- The earth wire should be longer than the

common wires.

- When installing, refer to the circuit dia-

gram on the chassis cover.

- Connect the wires firmly so that they

may not be pulled out easily.

CAUTION

According to the confirmation of the above

conditions, prepare the wiring as follows.

1 Never fail to have an individual power

circuit specifically for the air condi-

tioner. As for the method of wiring, be

guided by the circuit diagram posted

on the inside of control cover.

2 The screw which fasten the wiring in

the casing of electrical fittings are liable

to come loose from vibrations to which

the unit is subjected during the course

of transportation. Check them and

make sure that they are all tightly fas-

tened. (If they are loose, it could cause

burn-out of the wires.)

3 Specification of power source.

4 Confirm that electrical capacity is suffi-

cient.

5 See that the starting voltage is main-

tained at more than 90 percent of the

rated voltage marked on the name

plate.

6 Confirm that the cable thickness is as

specified in the power source specifi-

cation.

(Particularly note the relation between

cable length and thickness.

7 Always install an earth leakage circuit

breaker in a wet or moist area.

8 The following would be caused by volt-

age drop.

- Vibration of a magnetic switch, which

will damage the contact point, fuse

breaking, disturbance of the normal

function of the overload.

9 The means for disconnection from a

power supply shall be incorporated in

the fixed wiring and have an air gap

contact separation of at least 3mm in

each active(phase) conductors.

Leak testing

The air and moisture remaining in the refriger-

ant system have undesirable effects as indi-

cated below.

- Pressure in the system rises.

- Operating current rises.

- Cooling(or heating) efficiency drops.

- Moisture in the refrigerant circuit may freeze

and block capillary tubing.

- Water may lead to corrosion of parts in the

refrigeration system.

Therefore, after evacuating the system, take a

leak test for the piping and tubing between the

indoor and outdoor unit.
