Installation work for air outlet ductsCalculate the draft and external static pressure and select the length,shape and blowout.A Blowout duct2-spot, 3-spot and 4-spot with 200 type duct are the standardspecifications.Note (1) Shield the central blowout hole for 2-spot.(2) Shield the blowout hole around the center for 3-spot.Limit the difference in length between spots at less than 2:1.Reduce the length of duct as much as possible.Reduce the number of bends as much as possible. (Corner R shouldbe as larger as possible.)Use a band. etc. to connect the main unit and the blowout ductflange.Conduct the duct installation work before finishing the ceiling.Connection of suction, exhaust ductsa.Fresh air inletInlet can be selected from the side or rear faces depending on theworking conditions.Use the rear fresh air inlet when the simultaneous intake and exhaustis conducted. (Side inlet cannot be used.)b.Exhaust (Make sure to use also the suction.)Use the side exhaust port.Good exampleBad exampleBad exampleExhaust holeState seeing from top of unitSide fresh air inletRear fresh air inletFig.1 Fig.2Drainage TestConduct a drainage test after completion of the electrical work.During the trial, make sure that drain flows properly through thepiping and that no water leaks from connections.In case of a new building, conduct the test before it is furnishedwith the ceiling.Be sure to conduct this test even when the unit is installed in theheating season.Attached drain hose clampDrain pipingMain unitDrain situation can be checked with transparent socketRemove grommet.Make sure to installit back after test.Insert water supply hosefor 20 mm ~ 30 mm tosupply water.(Insert hose facingtoward bottom.)Pour water into a convex joint.ProceduresSupply about 1000 cc of water to the unit through the air outletusing a feed water pump.Check the drain while cooling operation.Before the electrical work has not been completed, connect a convexjoint in the drain pipe connection to provide a water inlet. Then, checkif water leaks from the piping system and that drain flows throughthe drain pipe normally.(1)(2)(3)(4)(a)(b)Ceiling surfaceHeatinsulation Suction panel(Silent panel)Air conditioner main unitSpecialblowout(Option)Blowout duct(Optional ormarketed item)Hole for checks p e c i a l i n l e t(option) (with airfilter)inlet duct(Optional ormarketed item)BACDrain PipeAir DuctInstallation Procedure23Installation Procedure
