TIPS FOR SAVING ENERGY
• 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.

Installation
•
Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant levels may cause failure of product.
•
Install the drain hose to ensure that water is drained away properly. A bad connection may cause
water leakage.
•
Keep level even when installing the product. To avoid vibration or water leakage.
•
Do not install the product where the noise or hot air from the outdoor unit could damage the neighborhoods. It may cause a problem for your neighbors.
•
Use two or more people to lift and transport the product. Avoid personal injury.
•
Do not install the product where it will be exposed to sea wind (salt spray) directly. It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause
product malfunction or inefficient operation.
Operation
•
Do not expose the skin directly to cool air for long periods of time. (Don't sit in the draft.) This could
harm to your health.
•
Do not use the product for special purposes such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of property.
•
Do not block the inlet or outlet of air flow. It may cause product failure.
•
Use a soft cloth to clean. Do not use harsh detergents, solvents, etc. There is risk of fire, electric
shock, or damage to the plastic parts of the product.
•
Do not touch the metal parts of the product when removing the air filter. They are very sharp! There
is risk of personal injury.
•
Do not step on or put anyting on the product. (outdoor units) There is risk of personal injury and failure of product.
•
Always insert the filter securely. Clean the filter every two weeks or more often if necessary. A dirty
filter reduces the efficiency of the air conditioner and could cause product malfunction or damage.
•
Do not insert hands or other objects through the air inlet or outlet while the product is operated.
There are sharp and moving parts that could cause personal injury.
•
Do not drink the water drained from the product. It is not sanitary and could cause serious health issues.

Precautions when laying power wiring
ENGLISH
WIRING CONNECTION
11
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.

• The circuit diagram is not subject to change without notice.
• Be sure to connect wires according to the wiring diagram.
• Connect the wires firmly, so that They won’t be pulled out easily.
• Connect the wires according to color codes by referring the wiring diagram.
• The Power cord connected to the unit should be selected according to the specifications.
14
CONNECTING PIPES
Cut the pipes and the cable.
- Use the accessory piping kit 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(4.9 ft) 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 to downward direction as you remove burrs in order
to avoid to let chips drop in the tubing.
Putting nut on
- Remove flare nuts attached to indoor and
outdoor units, than 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 dedicated flaring
tool for R410A as shown below.
Firmly hold copper tube in a bar(or die) as indicated dimension in the table above.
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.

Forming the piping
Form the piping by wrapping the connecting
portion of the indoor unit with insulation material and secure it with two kinds of vinyl tape.
- If you want to connect an additional drain
hose, the end of the drain outlet should be
routed above the ground. Secure the drain
hose appropriately.
In cases where the outdoor unit is installed
below the indoor unit perform the following.
1 Tape the piping, drain hose and connecting
cable from down to up.
2 Secure the tapped piping along the exterior
wall using saddle or equivalent.
ENGLISH
* When tighten the pipe, hold the haxagonal
body.
