Installation EDUS39-600-F1_a24 FXFQ-M3. SELECTING INSTALLATION SITEAttach an additional insulation pipe cover to the unit bodywhen it is believed that the relative humidity in the ceilingexceeds 80%. Use glass wool, polyethylene foam, or some-thing similar with a minimum 3/8 inch thickness as insulation.For this unit, you are able to select air flow direction.To enable the discharge of air in 2 or 3 directions, it is neces-sary to purchase the optional blocking pad kit.(1) Select an installation site where the following conditionsare fulfilled and that meets with your customer’s approval:• No possible dripping of water from the refrigerant pipe,drain pipe, or water pipe into the upper space of theindoor unit, including the back of the ceiling.• Optimum air distribution can be ensured.• Nothing blocks air passage.• Condensate can be properly drained.• False ceiling is not noticeably on an incline.• Sufficient clearance for maintenance and service canbe ensured.• Piping between indoor and outdoor units is possiblewithin the allowable limit. Refer to the installation man-ual of the outdoor unit.DANGER• Do not install unit in an area where flammable materials arepresent due to risk of explosion resulting in serious injury ordeath.WARNING• If supporting structural members are not strong enough totake the unit’s weight, the unit could fall out of place andcause serious injury.NOTE• Install the indoor and outdoor units, power supply wiringand connecting wires at least 3.5ft. away from televisions orradios in order to prevent image interference or noise.Depending on the radio waves, a distance of 3.5 ft. may notbe enough to eliminate the noise.(2) Ceiling heightThis indoor unit may be installed on ceilings up to 11.5 ft.(30, 36: 13.8 ft.) in height as shown in the following table:(3) Airflow directionThe below figures are approximations. Select airflowdirections best suited to the room and point of installation.For air discharge in 2 or 3 directions, it is necessary tomake field settings by remote controller and to close theair outlet(s). Refer to the section FIELD SETTING in theinstallation manual of the optional blocking pad kit.(4) Use suspension bolts for installation. Ensure theceiling is strong enough to support the weight of theunit If any risk, reinforce the ceiling before installingthe unit.(5) Refer to the installation pattern for instructions and tocheck for points requiring reinforcing.)(length: in.)Number of discharge outlets usedFXFQ12M~24M4-way airdischarge3-way airdischarge2-way airdischargeCeilingheight Standard 8.9 9.9 11.5Number of discharge outlets usedFXFQ30M·36M4-way airdischarge3-way airdischarge2-way airdischargeCeilingheight Standard 10.5 11.8 13.8Model HFXFQ12 · 18 · 24MVJU 9 7/16 or moreFXFQ30 · 36MVJU 11 3/4 or more[Air flow direction]Air discharge in4 directionsAir discharge in3 directionsAir discharge in2 directionsHH*59or more*59or more*59or more*59or moreAirdischargeAirdischarge39 3/8 or moreAirinletAir inletAir dischargeAirdischarge[Space required for installation]NOTE) Leave 7 7/8 or more space where markedwith the *, on sides where the air outlet is closed.
