Manual 2100-324Page 6INSTALLATIONLOCATIONGENERALThe unit must be located outside, or in a well ventilatedarea. It must not be in the space being heated or cooled. Asound absorbing material should be considered if the unitis to be installed in such a position or location that mightcause transmission of sound or vibration to the living areaor adjacent buildings.SLAB MOUNTINGIn areas where winter temperatures DO NOT go below32° F for periods over twelve hours, the unit may be slabmounted at grade level. When installing unit at gradelevel, install on a concrete slab at least four inches abovefinished grade level. Slab should have a slope toleranceaway from the building structure of at lease 1/4 inch perfoot, while being level from side to side. Place slab in alocation where runoff water from higher ground will notcollect around unit. See Figure 3.A minimum of 18 inches should be provided between thecoil inlet and any building surfaces. Provide at least fourfeet between coil outlet and any building wall, fences orother vertical structures. Provide a minimum of three feetclearance on the service access side of the unit. SeeFigure 4ROOF MOUNTINGWhen a unit is installed in areas where low ambienttemperatures or strong winter winds exist, it should beplaced for prevailing winter winds are not in direct linewith the outdoor coil. If this is not possible, a wind barriershould be constructed. Place barrier 24 inches from thecoil inlet side of the unit and in the direction of prevailingwinds. Size barrier at least the same height and width asthe unit. This may be necessary on ground levelinstallations, also. See Figure 5.WINTER INSTALLATION BELOW 32°FIn areas where winter conditions go below 32°F forextended periods, the unit must be elevated above themounting surface to prevent snowfall or ice accumulationfrom interfering with the operation of the unit. Aminimum of twelve inch elevation is recommended, whilegreater elevation may be required for areas of high snowaccumulation. Poured concrete, steel framework, brick,cement block, etc., can be utilized to construct a suitableraised mounting platform. See Figure 6.DUCT WORKRefer to Tables 4, 5 and 5A when designing duct work formaximum static pressure available with the specific modeland heater package being installed.TABLE 5ATYPICAL INSTALLATIONS1. ROOF MOUNTED – The unit is mounted on asturdy base on the roof of the building. Return air tothe unit is brought through a single return grille (grilleswith built-in filters are best since they enable easyaccess for filter changing). Return air ducts areattached to the lower section of the front panel.Supply air is brought from the unit to attic duct workor to a furred down hall. Supply air duct is attached tothe top of the front panel.CAUTION: All outdoor duct work must bethoroughly insulated and weatherproofed. Allattic duct work must be thoroughly insulated.Two inch thick insulation with suitable vaporbarrier is recommended for both outdoor andattic runs.In roof top installation, as in all installations, the airconditioner must be level from side to side. However,the unit should have a pitch along the length to assurecomplete external drainage of precipitation and ofdefrost condensate.2. CRAWL SPACE – Duct work installed in crawlspace must be well insulated and provided with avapor barrier. In addition, the crawl space must bethoroughly ventilated and provided with a good vaporbarrier as a ground cover. It is most desirable to installthe unit will be outdoors rather than inside the crawlspace, so that it will be readily accessible for service.PSEsehcnIH2O3A2411P12411HPteW/yrD1A8411P8401HPteW/yrD1A0601P0601HPteW/yrD01.2.3.4.5.5261/05615251/05510041/53410131/04310121/03210011/02110291/05910381/06810571/08710661/08610551/08510841/00510581/05810871/00810071/52715261/06610451/08515741/0051TABLE 5RATED CFM ANDEXTERNAL STATIC PRESSURE (ESP)WET COIL (COOLING)ledoMdetaRMFCdetaRPSEdednemmoceRegnaRwolFriA3A2411P 0041 02.
