A5LCY-II-2010 Application Information Installation Guideline Safety Precautions WARNING CAUTION 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 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}. Please take note of the following important points when installing. Do not install the unit where leakage of flammable 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 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 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. 12

Application Information A5LCY-II-2010 Piping Works Do not use contaminated or damaged copper tubing. Do not remove plastic, rubber plugs and brass nuts from the valves, fi ttings, tubings and coils until you are ready to connect suction or liquid line into valves or fi ttings. If any brazing work is required, ensure that the nitrogen gas is passed through coil and joints while the brazing work is being done. This will eliminate soot formation on the inside walls of the copper tubings.

Remove the caps from the valve and the service port. Connect the center of the charging gauge to the vacuum pump. Connect the charging gauge to the service port of the 3-way valve. Start the vacuum pump. Evacuate for approximately 30 minutes. The evacuation time varies with different vacuum pump capacity. Confi rm that the charging gauge needle has moved towards -760mmHg.

On the outdoor unit, open the suction valve (3 way) and liquid valve (2 way) (in anti-clockwise direction) with 4mm key for hexagon sacked screw. 28
Application Information A5LCY-II-2010 Charge Operation This operation must be done by using a gas cylinder and a precise weighing machine. The additional charge is topped-up into the outdoor unit using the suction valve via the service port. Remove the service port cap. Connect the low pressure side of the charging gauge to the suction service port center of the cylinder tank and close the high pressure side of the gauge. Purge the air from the service hose. Start the air conditioner unit. Open the gas cylinder and low pressure charging valve. When the required refrigerant quantity is pumped into the unit, close the low pressure side and the gas cylinder valve. Disconnect the service hose from service port. Put back the service port cap. Indoor Unit Liquid side Outdoor Unit Discharge valve Open Gas side Check valve Low Hi Close Suction valve Open Special Precautions when Dealing with R410A Unit R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential. Never use refrigerant other than R410A in an air conditioner which designed to operate with R410A. POE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22 compressor.during installation or servicing, extra precaution must be taken not to expose the R410A system too long to moist air. Residual POE oil in the piping and components can absorb moisture from the air. To prevent mischarging, the diameter of the service port on the fl are valve is different from that of R22. Use tools and materials exclusively for refrigerant R410A. Tools exclusively for R410A are manifold valve, charging hose, pressure gauge, gas leak detector, fl are tools, torque wrench, vacuum pump and refrigerant cylinder. As an R410A air conditioner incurs higher pressure than R22 units, it is essential to choose the copper pipes correctly. Never use copper pipes thinner than 0.8mm even though they are available in the market. If the refrigerant gas leakage occurs during installation / servicing, be sure to ventilate fully. If the refrigerant gas comes into contact with fi re, a poisonous gas may occur. When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigerant cycle. 29
