INSTALLATION MANUAL

This manual provides the procedures of installation to ensure a safe and good standard of operation for the air conditioner unit. Special adjustment may be necessary to suit local requirement.

Before using your air conditioner, please read this instruction manual carefully and keep it for future reference.

This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for commercial use by lay persons.

This appliance is not intended for use by persons, including children, with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

SAFETY PRECAUTIONS

WARNING

•Installation and maintenance should be performed by qualified persons who are familiar with local code and regulation, and experienced with this type of appliance.

•All field 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.

•Confirm 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 fire 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}.

CAUTION

Please take note ofthe following important points when installing.

• Ensure that the drainage piping is connected properly.

If the drainage piping is not connected properly, it may cause water leakage which will dampen the furniture.

•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 install the units at or near doorway.

•Do not operate any heating apparatus too close to the air conditioner unit or use in room where mineral oil, oil vapour or oil steam exist, this may cause plastic part to melt or deform as a result of excessive heat or chemical reaction.

•When the unit is used in kitchen, keep flour away from going into suction of the unit.

•This unit is not suitable for factory used where cutting oil mist or iron powder exist or voltage fluctuates greatly.

•Do not install the units at area like hot spring or oil refinery plant where sulphide gas exists.

•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.

•Don’t use joined and twisted wires for incoming power supply.

•The equipment is not intended for use in a potentially explosive atmosphere.

NOTICE

Disposal requirement [For European Union (EU) only]

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 other parts must be done by a qualified 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 correct disposal, 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.

INSTALLATION OF THE INDOOR UNIT

1. Preliminary Site Survey

Be sure to read this manual before installing the air-conditioner indoor unit.

•Voltage supply fluctuation must not exceed +10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause high supply fluctuation.

•Ensure that the location is convenient for wiring, piping and drainage.

•Do not exert pressure on the resin parts when opening the unit or when moving it after opening.

•Do not move the unit from packaging while moving, until it reaches the installation site. Use safe material or protection plates when unpacking it or lifting it to avoid damage or scratches to the unit.

•All wires must be firmly connected.

•Make sure all the wire not touching the refrigerant piping, compressor or any moving parts of the fan motor.

•The connecting wire between the indoor unit and the outdoor unit must be clamped on the wire clamps.

•The power supply cord must be equivalent to H07RN-F which is the minimum requirement.

•When attaching the terminal box lid, make sure do not pinch any wires.

•After all the wiring connections are done, fill in any gaps/holes with insulation (procured locally) to prevent small animals and insects entering the unit from outside.

•Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching to the indication on terminal block. (Refer to the wiring diagram attached on the unit).

Round crimp-style terminal

Step to connect the installation wire:

•Used the correct screwdriver for tightening the terminal screws. If the block is too small, the mad of the screw might be damaged and the screw will not be properly tightened. If tightening too hard, screw might be damaged.

•Do not connect wire at different gauge to the same proper supply terminal.

•Use specified electric wire. Connect the wire securely to the terminal. Lock the wire down without applying excessive force to the terminal.

•Keep wiring in mat order and not to obstruct other equipment such as popping open the terminal box lid.
