Before hanging theceiling unit, test the strength of each attached suspensionbolt.(5) Screw in the suspension bolts, allowing them to protrude fromthe ceiling (Figs. 3-11 and 3-12).The distance of each exposed bolt must be of equal lengthwithin 1-31/32” (50 mm). (Fig. 3-13)Ceiling surfaceWithin1-31/32”(50 mm)UnitBracketFig. 3-13(6) Carry out the preparation for suspending the indoor unit.The suspension method varies depending on whether there isa suspended ceiling or not. (Figs. 3-14 and 3-15)(7) Suspend the indoor unit as follows:a) Install the bracket to the suspension bolt.Stick it onto the ceiling surface.

For the installation to be correct, leave a clearanceof about 1-31/32” (10 mm) between the ceiling panel and the ceilingsurface and fill the gap with an appropriate insulation or filler material.3-4. Duct for Fresh Air (Field supply)There is a outside air intake duct connection port (cut out hole) at theleft-rear of the indoor unit for drawing in fresh air. If it is necessaryto draw in fresh air, remove the cover by opening the hole andconnecting the duct to the indoor unit through the connection port.(Refer to Fig. 3-3)* It is impossible to commoditize with the subpart Solenoid Valve Relay Kit(part of Solenoid Valve Kit).3-5. Shaping the Tubing● The positions of the refrigerant tubing connections are shown in thefigure below. (The tubing can be routed in 3 directions.) (Fig. 3-18)* When routing the tubing out through the top or right sides, cut out thecover of the top panel and cut notches in the side panel (Refer to Fig. 3-3).Fig. 3-18Use a box cutter or similar toolto cut out the part of the coverindicated by the marked area(Fig. 3-19), to match the positionsof the tubes.Pass all refrigerant tubes through thishole.Fig. 3-193-6. Installing the Drain Pipe● Prepare hard PVC pipe for the drain and connect it to the indoorunit drain pipe with the supplied hose band to prevent water leaks.● Measure the thickness of the wall from the inside to the outside andcut PVC pipe at a slight angle to fit. Insert the PVC pipe in the wall.(Fig. 3-21)Cover
