TIPS FOR SAVING ENERGY

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

tricity.

• 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 condition-

er 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.

performance of your product

WARNING

It can result in serious injury or death when the directions are ignored

CAUTION

It can result in minor injury or product damage when the directions are ignored

WARNING

• Installation or repairs made by unqualiﬁed persons can result in hazards to you and others.

• Installation work must be performed in accordance with the National Electric Code by quali-

ﬁed and authorized personnel only.

• The information contained in the manual is intended for use by a qualiﬁed service technician

familiar with safety procedures and equipped with the proper tools and test instruments.

• Failure to carefully read and follow all instructions in this manual can result in equipment mal-

function, property damage, personal injury and/or death.

Installation

• Always perform grounding. Otherwise, it may cause electrical shock.

• Don’t use a damaged power cable. Otherwise, it may cause a ﬁre or electrical shock.

• For installation of the product, always contact the service center or a professional installation

agency. Otherwise, it may cause a ﬁre, electrical shock, explosion or injury.

• Securely attach the electrical part cover to the indoor unit and the service panel to the outdoor

unit. If the electrical part cover of the indoor unit and the service panel of the outdoor unit are

not attached securely, it could result in a ﬁre or electric shock due to dust, water, etc.

• Always install an earth leakage circuit breaker and a dedicated switching board. No installation

may cause a ﬁre and electrical shock.

• Do not keep or use ﬂammable gases or combustibles near the air conditioner. Otherwise, it

may cause a ﬁre or the failure of product.

Electrical Wiring

Perform the electrical wiring work according

to the electrical wiring connection.

- All wiring must comply with local require-

ments.

- Select a power source that is capable of sup-

plying the current required by the air condi-

tioner.

- Use a recognized ELCB(Electric Leakage

Circuit Breaker) between the power source

and the unit. A disconnection device to ade-

quately disconnect all supply lines must be

ﬁtted.

ENGLISH

Use round pressure terminals for connections to the power terminal block.

When none are available, follow the instructions below.

- Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power

wiring may cause abnormal heat.)

- When connecting wiring which is the same thickness, do as shown in the figure below.

- For wiring, use the designated power wire and connect firmly, then secure to prevent outside

pressure being exerted on the terminal block.

- Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small

head will strip the head and make proper tighterning impossible.

- Over-tightening the terminal screws may break them.

CONNECTING PIPES

ENGLISH

Preparation of Piping

Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following

procedure.

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

distance.

- Cut the cable 1.5 m longer than the pipe

length.

Burrs removal

- Completely remove all burrs from the cut

cross section of pipe/tube.

- 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 bar in the

dimension shown in the table below.

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.
