TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:

• Do not cool excessively indoors. This may be harmful to 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.

• 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

Electrical Wiring

Perform the electrical wiring work according
to the electrical wiring connection.

- All wiring must comply with local require­ments.

- Select a power source that is capable of sup­plying the current required by the air condi­tioner.

- Use a recognized ELCB(Electric Leakage
Circuit Breaker) between the power source
and the unit. A disconnection device to ade­quately disconnect all supply lines must be
fitted.

Precautions when laying power wiring

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

Round pressure terminal

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.

Preparation of Piping

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

C

- Use the piping kit accessory or the pipes pur­chased 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.

- 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.

- 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)
