After completing the installation, make sure that the unit operates properly during the start-up operation. Instruct the customer how to operate and maintain the unit. Inform customers that they should store this Installation Manual with the Operation Manual for future reference. Always use a licensed installer or contractor to install this product. Improper installation can result in water or refrigerant leakage, electrical shock, fire, or explosion. Meanings of DANGER, WARNING, CAUTION, and NOTE symbols: • • • • • • 16 DANGER .............. Indicates an imminently hazardous situation which, if not avoided, results in death or serious injury. WARNING ............ Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION ............. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices NOTE .................... Indicates situations that may result in equipment or propertydamage accidents only. Do not ground units to water pipes or telephone wires because incomplete grounding could cause a severe shock hazard resulting in severe injury or death. Do not ground ss to lightning rods because lightning strikes can cause a severe shock hazard resulting in severe injury or death. Do not install unit in an area where flammable materials are present due to risk of explosion resulting in serious injury or death. Do not ground units to gas pipes because a gas leak can result in an explosion causing serious injury or death. Refrigerant gas is heavier than air and displaces oxygen. A massive leak can lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death. If the refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan, heater, stove, or cooking device. Exposure to this gas could result in severe injury or death. After completing the installation work, check that the refrigerant gas does not leak. Refrigerant gas can produce toxic gas if it comes in contact with fire such as from a fan, heater, stove, or cooking device. Exposure to this gas can cause in severe injury or death. Children playing with plastic bags face the danger of death by suffocation. Tear apart and throw away plastic packaging so that children will not play with them. EDUS39-600-F7 • Safely dispose of the packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. WARNING • Ask your dealer or an authorized personnel to carry out installation work. Do not try to install the unit by yourself. Improper installation may result in water leakage, electric shocks, or fire. • Perform installation work in accordance with this installation manual. Improper installation may result in water leakage, electric shocks, or fire. • Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in water leakage, electric shocks, fire, or the unit falling. • Install the air conditioner on a foundation strong enough to withstand the weight of the unit. A foundation of insufficient strength may result in the equipment falling and causing injuries. • Carry out the specified installation work after taking account of strong winds, typhoons, or earthquakes. Improper installation work may result in the equipment falling and causing accidents. • Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by an authorized personnel according to local laws, regulations, and this installation manual. An insufficient power supply capacity or improper electrical construction may lead to electric shocks, or fire. • Make sure that all wiring is secured, the specified wires are used, and no external forces act on the terminal connections or wires. Improper connections or installation may result in fire. • When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that the electric parts box lid can be securely fastened. Improper positioning of the electric parts box lid may result in electric shocks, fire, or the terminals overheating. • Before touching electrical parts, turn off the unit. • Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock. • Be sure to install an earth leakage breaker. Failure to install a ground leakage breaker may result in electric shocks, or fire. • Do not install the air conditioner where the following conditions exist: (a) Mineral oil mist or an oil spray or vapor is produced, for example in a kitchen. Plastic parts may deteriorate and fall off or water may leak. (b) Corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered parts can cause refrigerant leaks. (c) Machinery is emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the equipment.(d) Where flammable gases may leak, where there are carbon fiber or ignitable dust suspensions in FXLQ-M / FXNQ-M EDUS39-600-F7 the air, or where volatile liquids such as thinner or gasoline are handled. Operating the unit in such conditions may result in fire. • Heat exchanger fins are sharp enough to cause cuts. To avoid injury wear gloves or cover the fins when you are working around them. • Refrigerant pipes may be very hot or very cold during or immediately after operation. Installation • • • CAUTION • While following the instructions in this installation manual, insulate piping in order to prevent condensation. Improper piping insulation may result in water leakage and property damage. • Be very careful about product transportation. Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous. • Safely dispose of the packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. Tear apart and throw away plastic packaging bags so that children do not play with them. If children play with a plastic bag which was not torn apart, they face the risk of suffocation. • Do not turn off the power immediately after stopping operation. Always wait at least five minutes before turning off the power. Otherwise, water leakage or other problems may occur. • Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke, or fire. Please instruct the customer to keep the area around the unit clean. NOTE • • • using an incorrect refrigerant prevents normal operation of the unit. The accessories needed for installation must be retained in your custody until the installation work is completed. Do not discard them! Decide upon a line of transport. Leave the unit inside its packaging while moving until reaching the installation site.

NOTE • Setting the unit at an angle opposite to the drain piping might cause leaks. 6. FXNQ Lift legs. Installation screw Lower case of remote controller Lid of control panel REFRIGERANT PIPING WORK For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit. Execute heat insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, a water leakage can result. When using a heat pump, the temperature of the gas piping can reach up to approximately 250°F, so use sufficiently resistant insulation. In cases where the temperature and humidity of the refrigerant piping sections might exceed 86°F or RH80%, reinforce the refrigerant insulation by 13/16” or thicker. Condensate may form on the surface of the insulating material. Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not possible if the types of refrigerant are not the same. NOTE NOTE • Use the installation mount for installation. Check whether the wall is strong enough to bear the weight of the unit or not. If there is a risk, reinforce the wall before installing the unit. • The unit requires a minimum 2.5 inch clearance on the underside for air intake. Ensure the unit is level when installed so that drainage flows smoothly. If tilted or on an incline, water can leak. • Operating sound may be louder if installed on a more solid wall. FXLQ-M / FXNQ-M • Use a pipe cutter and flare suitable for the type of refrigerant. • To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape. • Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such as air, etc. • If any refrigerant gas leaks while working on the unit, immediately ventilate the room. When connecting refrigerant piping: • Ensure that theoutdoor unit is charged with refrigerant. • Use copper alloy seamless pipes. • To prevent flare nut cracking and gas leaks, be sure to use both a spanner and torque wrench together, as shown in the drawing, when connecting or disconnecting pipes to / from the unit. • Refer to Table 2 for the dimensions of flare. 20 Installation EDUS39-600-F7 • When connecting the flare nut, coat the flare section (both inside and outside) with ester oil or ether oil, rotate three or four times first, then screw in. • Refer to the Table 2 for tightening torque. • After inspecting pipe joints for gas leakage, be sure to insulate with the accessory joint insulation for fitting (3) (4) while referring to the figure below. Fasten both ends with clamps (6). Wrap only the gas line side with the sealing pad (5). Bend the pad over the insulation for fitting (union) from above. Ester oil or ether oil. DANGER • Use of oxygen may cause an explosion resulting in serious injury or death. Only use nitrogen gas. • Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. Exposure to this gas could cause severe injury or death. • Before brazing local refrigerant piping, nitrogen gas shall be blown through the piping to expel air from the piping. If brazing is done without nitrogen gas blowing, a large amount of oxide film develops inside the piping, and could cause system malfunction. • When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution or while inserting nitrogen into the refrigerant piping. Once this is done, connect the indoor unit with a flared or a flanged connection. • Nitrogen should be set to 2.9 psi with a pressure-reducing valve if brazing while inserting nitrogen into the piping. Torque wrench Spanner Piping union Flare nut Insulation for fitting (accessory) (4) (For liquid pipe) Insulation for fitting (accessory) (3) (For gas pipe) • CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filter metal (BCuP) which does not require flux. Flux has an extremely negative effect on refrigerant piping systems. For instance, if chlorine based flux is used, it will cause pipe corrosion. If the flux contains fluorine, it will damage the refrigerant oil. Refrigerant piping Part to be brazed Taping hands valve Pressurereducing valve Nitrogen Liquid pipe Nitrogen Clamp (6) (accessory) NOTE Gas pipe Fig. 1 Use Table 3 as a reference if a torque wrench is not available. Once work is complete, make sure there is no gas leaking. As the flare nut is tightened with the wrench, the torque suddenly increases. From that position, tighten the nut to the angle shown on Table 3 . • Make absolutely sure to execute heat insulation works on the pipe-connecting section after checking gas leakage by thoroughly studying the following figure and using the attached heat insulating materials for fitting (3) and (4). (Fasten both ends with the clamps (6) (accessory).) (Refer to Fig. 1) CAUTION Use the flare nuts attached with the unit. Not recommended but if no torque wrench is available, refer to table 2 for tightening torque: Table 2 Pipe size Tightening torque (ft-lbf) Flare dimensions A (in.) φ 1/4” 10.5 – 12.7 0.343 – 0.358 φ 3/8” 24.1 – 29.4 0.504 – 0.520 φ 1/2” 36.5 – 44.5 0.638 – 0.654 φ 5/8” 45.6 – 55.6 0.760 – 0.776 Flare shape (in.)
