Unit InstallationTable 1 - Total unit weight and corner weights 7069727190899190Installations, Limitations andRecommendationsThe general location of the air handleris normally selected by the architect,contractor and/or buyer. For properinstallation, the following items mustbe considered.a. Available power supply must agreewith electrical data on componentnameplate.b. Air handler shipped wired for 380volt applications.c. If external accessories are installedon the unit, additional clearancemust be provided.d. All duct work should be properlyinsulated to prevent condensationand heat loss.e. Refrigerant gas piping must beinsulated.Caution: Properly insulate allrefrigerant gas piping to preventpossible water damage due tocondensation and to preventcapacity loss and possiblecompressor damage.It is recommended that the outlinedrawings (Pages 12-14) be studiedand dimensions properly noted andchecked against selected installationsite. By noting in advance whichknockouts are to be used, properclearance allowances can be made forinstallation and possible future service.Important: If adding externalaccessories to the unit,additional clearances must beconsidered for the overall spaceneeded.TWE-IOM01-EN0213Corner WeightsWhen installing these units “freestanding” with discharge grills andisolaters, a top support with isolatershould be added to prevent tipping.Support and isolater can be attachedto a wall or other appropriate structure.Caution : Use spreader bars toprevent straps from damagingthe unit. Install the bars betweenlifting straps, both underneaththe unit and above the unit. Thiswill prevent the straps fromcrushing the unit cabinet ordamaging the unit finish.Installation ConsiderationFor proper installation and operation,check each of the following beforemounting the units.a. Space Requirement andClearanceAllow adequate space for the unit andfree air or service clearance. SeeFigure 1a.For installation of accessoriesavailable for this air handler, followthe instructions packed with eachaccessory.900 mm.Lifting RecommendationsBefore preparing the unit for lifting, thecenter of gravity should be determinedfor lifting safety. Because ofplacement of internal components, theunit weight may be unevenlydistributed. Approximate total unitweight and corner weights are given inTable 1.WARNING: On sitelifting equipment must becapable of lifting the weight ofthe unit with an adequate safetyfactor. The use of under-capacitylifting devices may result inpersonal injury or death andcause damage to the unit.The crated unit can be moved using aforklift of suitable capacity. For liftingthe unit into an elevated mountingposition, run lifting straps or slingsunder the unit and attach securely tothe lifting device. Use spreader barsto protect the unit casing from damage. Test lift the unit to determineproper balance and stability.850 mm.850 mm.Figure 1aSpace requirement for TWE modelVertical TypeFor servicing and routine maintenance,provide access to the unit throughremovable panels in the ceiling seeFigure 1b.850 mm.850 mm.850 mm.Figure 1bSpace requirement for TWE modelHorizontal Type5
Unit Installationb. Location, Mounting andPositioningBefore installing any unit make sureproper preparation has been made ateach unit locating for piping andelectrical connections.W#4Caution: Before hanging the uniton suspension rods, reinforcethe cabinet around theknockouts, using a large washerinside the cabinet. Washershould be between the skin ofthe air handler and the nut onthe suspension rod.W#3Align holes (knockouts) in the cabinetwith structural supports and securesuspensions rods to the structure, thento the air handler cabinet. If knockoutlocations do not permit proper alignmentwith existing structure, it may benecessary to field fabricate crossmembers on existing structural beams.W#2W#1Note: When other than bottomreturn is to be used, side panelremoved for return ductinstallation, must be securedover the bottom opening.LevelingFigure 2aW#3W#2W#4W#1Figure 2bHorizontal SuspensionIf the air handler will be suspended, usea suspension mounting kit to isolate theunit from the structure. This is usuallyaccomplished through the use of springor rubber isolators, which are offered asan accessory. Mounting rods must befield supplied. Isolator selection isdependent upon total unit weight,including accessories. Approximate unitweights are provided in Table 1.6This air handler has a double slopeddrain pan. In order to assure properdrainage along the length of drain pan, itis important to have the unit properlyleveled. Be sure the air handler is levelor slightly sloped in the direction of thecondensate connection.Refrigerant Piping PreparationThe air handler is designed so thatrefrigerant piping can enter from eitherthe left or right hand side. The airhandler is shipped with the intent, thatthe refrigerant, lines will enter from theright hand side. To convert to left handentry, unbraze the elbow on the suctionline and rotate 180 degrees and rebraze.(See Figures 3 and 4).Caution: Protect adjacentsurfaces from heat damage,when brazing in and around theair handler.These air handlers are shippedwith a holding charge in the coil.Cut the process tube or puncturethe cap to bleed off the nitrogenprior to any brazing. Temporarilycap off tubes if the refrigerantline connections are to be madelater. You will find a cloth bagthat contains two (2) brassclamps (straps) and cork"impregnated insulation materialapproximately 9" long by 4"wide, for attaching and insulating the expansion valve bulb tothe suction line. On dual circuitsair handlers there will be two (2)cloth bags with like parts.Auxiliary Drain PanRefrigerant PipingA field fabricated auxiliary drain panshould be installed under the unit for allhorizontal applications, and when airhandlers are installed above ceilings orin other locations where condensateoverflow may cause damage. This drainpan will eliminate any excesscondensation that may be due toextreme humidity or an obstructed drainin the primary drain pan. Drain linesfrom this pan must be installed, butshould not be connected to the primarydrain line from the unit, isolate theauxiliary drain pan from both the airhandler and the structure.Installation, brazing, leak testing, andevacuation of refrigerant lines arecovered in the installation instructionspackaged with the outdoor unit. Readthe instructions before beginninginstallation of refrigerant lines.On air handlers that will have refrigerantlines entering the cabinet from the rightside, remove the split rubber grommetfrom the knockout in the end of the airhandler. Uncoil the cap tube with thebulb attached at the expansion valveand place the grommet on the cap tube.With the grommet around the tube, pushthe bulb through the hold and positionthe grommet back into it’s originalposition. One bulb and cap tube onsingle circuit units and 2 bulb (s)approximately 45 degrees off vertical, 10to 12 inches outside of the air handler.(See Figure 3 and 4.)Installation PreparationsThe final position must be dictated byrequired service access to unit, weightdistribution over structural supports, andby the locations of electrical, refrigerantand condensate drainage connections.TWE-IOM01-EN0213
Unit InstallationOn air handlers that will haverefrigerant lines entering the cabinetfrom the left side, the bulb(s) should beattached to the suction tube(s) insidethe cabinet, in the same manner asabove, approximately 10" from the leftend of the unit.After attaching to the suction line(s),either inside or outside of the cabinet,wrap the cork impregnated insulationaround the bulb(s) and suction tube(s).Refrigerant piping should then rtant : Ensure that therefrigerant lines passing throughthe cabinet are not resting onsharp sheet metal edges.DRAIN PANVERTICALDRAIN CONNECTIONSFigure 53/4" GALVANIZEDPIPE & FITTINGSNIPPLERepositioning Drain PanMaterials1Tea4" MIN.NIPPLE2"DIA3/4"DIALEFT SIDE HOOK UP(OPTIONAL)RIGHT SIDE HOOKUP (STANDARD)2-3/4"MIN.1Plug3Street Ell15-1/2" NippleFigure 6aThese air handlers come with onedrain pan that can be installed in anyone of four positions; this allows forvertical or horizontal application andleft or right condensate lineconnection.
