If the ceiling opening is larger, add extra ceilingmaterial.▪ Make sure the unit and its hanger brackets (suspension) arecentered within the ceiling opening.(mm)cdABAB533350575cd533575baA 585~660 mm: In case of installation with BYFQ60B585~595 mm: In case of installation with BYFQ60CB 700 mm: In case of installation with BYFQ60B620 mm: In case of installation with BYFQ60Ca Drain pipingb Refrigerant pipingc Hanger bracket pitch (suspension)d UnitThenIf A B CACBBYFQ60B≥585 mm 5 mm 57.5 mm≤660 mm 42.5 mm 20 mmBYFQ60C≥585 mm 5 mm 17.5 mm≤595 mm 10 mm 12.5 mmA Ceiling openingB Distance between the unit and the ceiling openingC Overlap between the decoration panel and the suspendedceiling▪ Level. Make sure the unit is level at all 4 corners using a level or awater-filled vinyl tube.cbbaa Levelb Vinyl tubec Water levelNOTICEDo NOT install the unit tilted. Possible consequence: Ifthe unit is tilted against the direction of the condensate flow(the drain piping side is raised), the float switch mightmalfunction and cause water to drip.6.2.3 Guidelines when installing the drainpipingMake sure condensation water can be evacuated properly. Thisinvolves:▪ General guidelines▪ Connecting the drain piping to the indoor unit▪ Checking for water leaksGeneral guidelines▪ Pipe length. Keep drain piping as short as possible.▪ Pipe size. Keep the pipe size equal to or greater than that of theconnecting pipe (vinyl pipe of 25 mm nominal diameter and32 mm outer diameter).▪ Slope. Make sure the drain piping slopes down (at least 1/100) toprevent air from being trapped in the piping. Use hanging bars asshown.1~1.5 m aa Hanging barO AllowedX Not allowed▪ Condensation. Take measures against condensation. Insulatethe complete drain piping in the building.▪ Rising piping. If necessary to make the slope possible, you caninstall rising piping.▪ Drain hose inclination: 0~75 mm to avoid stress on the pipingand to avoid air bubbles.▪ Rising piping: ≤300 mm from the unit, ≤630~675 mm(depending on the decoration panel used) perpendicular to theunit.AB≤3000~751000~1500(mm)bab ca dd
