Installation Guideline
Safety Precautions
Installation and maintenance should be performed by qualifi ed persons who are familiar with local code and regulation, and experienced with this type of appliance. All fi eld wiring must be installed in accordance with the national wiring regulation. Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring work according to the wiring diagram. The unit must be GROUNDED to prevent possible hazard due to insulation failure. All electrical wiring must not touch the refrigerant piping or any moving parts of the fan motors. Confi rm that the unit has been switched OFF before installing or servicing the unit. Disconnect from the main power supply before servicing the air conditioner unit. DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks which may result in fi re hazards. Keep the indoor and outdoor units, power cable and transmission wiring, at least 1m from TVs and radios, to prevent distorted pictures and static. {Depending on the type and source of the electrical waves, static may be heard even when more than 1m away}.
Please take note of the following important points when installing.
Do not install the unit where leakage of fl ammable gas may occur.
If gas leaks and accumulates around the unit, it may cause fi re ignition.
Ensure that drainage piping is connected properly.
If the drainage piping is not connected properly, it may cause water leakage which will dampen the furniture.
Do not overcharge the unit.
This unit is factory pre-charged. Overcharge will cause over-current or damage to the compressor.
Ensure that the unit’s panel is closed after service or installation.
Unsecured panels will cause the unit to operate noisily.
Sharp edges and coil surfaces are potential locations which may cause injury hazards. Avoid from being in contact with these places. Before turning off the power supply, set the remote controller’s ON/OFF switch to the “OFF” position to prevent the nuisance tripping of the unit. If this is
not done, the unit’s fans will start turning automatically when power resumes, posing a hazard to service personnel or the user.
Do not operate any heating apparatus too close to the air conditioner unit. This may cause the plastic panel to
melt or deform as a result of the excessive heat.
Ensure the color of wires of the outdoor unit and the terminal markings are same to the indoors respectively. IMPORTANT : DO NOT INSTALL OR USE THE AIR CONDITIONER UNIT IN A LAUNDRY ROOM. Do not use joined and twisted wires for incoming power supply.
NOTICE
Disposal requirements
Your air conditioning product is marked with this symbol. This means that electrical and electronic products shall not be mixed with unsorted household waste. Do not try to dismantle the system yourself: the dismantling of the air conditioning system, treatment of the refrigerant, of oil and of other parts must be done by a qualifi ed installer in accordance with relevant local and national legislation. Air conditioners must be treated at a specialized treatment facility for re-use, recycling and recovery. By ensuring this product is disposed of correctly, you will help to prevent potential negative consequences for the environment and human health. Please contact the installer or local authority for more information. Batteries must be removed from the remote controller and disposed of separately in accordance with relevant local and national legislation.

4) Refrigerant Piping
When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant fl ow increases, thus lowering the cooling capacity, and as the result the compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below:
