The interior compartment of the remote controller contains several features to facilitate automatic operation, easy logically displayed for easy use.

•Simple One-touch Remote Controller

The remote controller has several features to facilitate automatic operation.

•24-Hour ON or OFF Timer

This timer can be set to automatically turn the unit on or off at any time within a 24 hour period.

•1-Hour OFF Timer

This timer can be set to automatically turn off the unit at any time after one hour.

•Night Setback

This function saves energy by controlling operation to provide a quieter operating sound than normal.

•Automatic and 3-step Fan Speed

Auto/High/Medium/Low

•Air Sweep Control

This function moves a flap up and down in the air outlet, directing air in a sweeping motion around the room and providing comfort in every corner.

•Auto. Flap Control

This automatically sets the flap to the optimum position during heating, cooling, and drying operation.

•Hot Start Heating System

Right from the start, the air is warm and comfortable. This system prevents any cold blasts at the beginning while the heat pump is warming up, or even defrosting.

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 heatgenerating 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

1.All wiring must conform to the local electrical codes. Consult your dealer or a qualified electrician for details.

2.Each unit must be properly grounded with a ground (or earth) wire or through the supply wiring.

3.Wiring must be done by a qualified electrician.

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 this Instruction Manual 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 this Instruction Manual.

•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.

•Do not swallow the battery.

•After removing the battery from remote controller, keep it away from the reach of children. The battery can cause death by suffocation if swallowed.

•When inserting the battery, make sure the polarities (+ and -) are correct.

				• 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.
				• Refrigerant gas leakage may cause fire.
				• For safety, be sure to turn the air conditioner off and also to
				disconnect the power before cleaning.
				• 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.
CAUTION
				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 1.5m away from the unit.
				• Do not let children play with the air conditioner.

				(1) This device may not cause harmful interference, and (2) this device must
				accept any interference received, including interference that may cause
				undesired operation.
				• This equipment has been tested and found to comply with the limits for
				a Class B digital device, pursuant to part 15 of the FCC Rules.
				These limits are designed to provide reasonable protection against harmful
				interference in a residential installation. This equipment generates, uses and
				can radiate radio frequency energy and, if not installed and used in
				accordance with the instructions, may cause harmful interference to radio
				communications. However, there is no guarantee that interference will not
				occur in a particular installation. If this equipment does cause harmful
				interference to radio or television reception, which can be determined by
				turning the equipment off and on, the user is encouraged to try to correct the
				interference by one or more of the following measures:
				• Reorient or relocate the receiving antenna.
				• Increase the separation between the equipment and receiver.
				• Connect the equipment into an outlet on a circuit different from that to which
				the receiver is connected.
