INSTALLATION LOCATION
•We recommend that this air conditioner be installed properly by qualified installation technicians in accordance with the Installation Instructions provided with the unit.
•Before installation, check that the voltage of the electric supply in your home or office is the same as the voltage shown on the nameplate.
•Do not install this air conditioner where there are fumes or flammable gases, or in an extremely humid space such as a greenhouse.
•Do not install the air conditioner where excessively high heat-generating objects are placed.
Avoid: To protect the air conditioner from heavy corrosion, avoid installing the outdoor unit where salty sea water can splash directly onto it or in sulphurous air near a spa.
ELECTRICAL REQUIREMENTS
•All wiring must conform to the local electrical codes. Consult your dealer or a qualified electrician for details.
•It is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD) to prevent electric shock or fire.
•Each unit must be properly grounded with a ground (or earth) wire or through the supply wiring.
•Wiring must be done by a qualified electrician.
To warm up the system, the power mains must be turned on at least five (5) hours before operation. Leave the power mains ON unless you will not be using this appliance for an extended period.
NOTE Pull off the power plug from a receptacle, or switch off the breaker, or switch off the power disconnecting mean to isolate the air conditioner from the main power supply when not in use for a long time.
SAFETY INSTRUCTIONS
•Read these Operating Instructions carefully before using this air conditioner. If you still have any difficulties or problems, consult your dealer for help.
•This air conditioner is designed to give you comfortable room conditions. Use this only for its intended purpose as described in these Operating Instructions.
•Confirm to authorized dealer or specialist on usage of specified refrigerant type. Using of refrigerant other than the specified type may cause product damage, burst and injury etc.
•Never touch the unit with wet hands.
•Never use or store gasoline or other flammable vapor or liquid near the air conditioner — it is very dangerous.
•Do not use this appliance in a potentially explosive atmosphere.
•This air conditioner has no ventilator for intaking fresh air from outdoors. You must open doors or windows frequently when you use gas or oil heating appliances in the same room, which consume a lot of oxygen from the air. Otherwise there is a risk of suffocation in an extreme case.
•To prevent possible hazards from insulation failure, the unit must be grounded.
•Do not clean inside the indoor and outdoor units by users. Engage authorized dealer or specialist for cleaning.
•In case of malfunction of this appliance, do not repair by yourself. Contact to the sales dealer or service dealer for a repair.
•Check for a leaking refrigerant! Refrigerant gas may produce a toxic gas if it comes in contact with fire.

•For safety, be sure to turn the air conditioner off and also to disconnect the
power before cleaning or servicing.
• Pull off the power plug from a receptacle, or switch off the breaker, or switch off the power disconnecting mean to isolate the air conditioner from the main power supply in case of emergency.
• Do not turn the air conditioner on and off from the power mains switch. Use the ON/ OFF operation button.
• Do not stick anything into the air outlet of the outdoor unit. This is dangerous because the fan is rotating at high speed.
• Do not touch the air inlet or the sharp aluminum fins of the outdoor unit. You may get injured.
•Keep the fire alarm and the air outlet at least 5 feet (1.5 m) away from the unit.
•Do not let children play with the air conditioner.
•Do not cool or heat the room too much if babies or invalids are present.
• Do not sit or step on the unit. You may fall down accidentally.
• Do not stick any object into the FAN CASE. You may be injured and
the unit may be damaged.
The compressor may occasionally stop during thunderstorms.
This is not a mechanical failure. The unit automatically recovers after a few minutes.
