2INSTALLATION RECOMMENDATIONSNOTE: In some cases noise in the living area has been traced togas pulsations from improper installation of equipment.1. Locate unit away from windows, patios, decks, etc. whereunit operation sound may disturb customer.2. Ensure that vapor and liquid tube diameters are appropriatefor unit capacity.3. Run refrigerant tubes as directly as possible by avoiding un-necessary turns and bends.4. Leave some slack between structure and unit to absorb vi-bration.5. When passing refrigerant tubes through the wall, seal open-ing with RTV or other pliable silicon--based caulk. (See Fig.1.)6. Avoid direct tubing contact with water pipes, duct work,floor joists, wall studs, floors, and walls.7. Do not suspend refrigerant tubing from joists and studs witha rigid wire or strap which comes in direct contact withtubing (See Fig. 1.)8. Ensure that tubing insulation is pliable and completely sur-rounds vapor tube.9. When necessary, use hanger straps which are 1 in. wide andconform to shape of tubing insulation. (See Fig. 1.)10. Isolate hanger straps from insulation by using metal sleevesbent to conform to shape of insulation.When outdoor unit is connected to factory--approved indoor unit,outdoor unit contains system refrigerant charge for operation withARI rated indoor unit when connected by 15 ft (4.57 m) offield--supplied or factory accessory tubing. For proper unitoperation, check refrigerant charge using charging informationlocated on control box cover and/or in the Check Charge section ofthis instruction.IMPORTANT: Maximum liquid--line size is 3/8--in. OD for allresidential applications including long line applications.IMPORTANT: Always install the factory--supplied liquid--linefilter drier. If replacing the filter drier, refer to Product Data Digestfor appropriate part number. Obtain replacement filter driers fromyour distributor or branch.INSTALLATIONINSULATIONVAPOR TUBELIQUID TUBEOUTDOOR WALL INDOOR WALLLIQUID TUBEVAPOR TUBEINSULATIONCAULKAvoid contact between tubing and structureNOTE:THROUGH THE WALLHANGER STRAP(AROUND VAPORTUBE ONLY)JOIST1” (25.4 mm) MIN.SUSPENSIONA94026Fig. 1 -- Connecting Tube InstallationSpecifications for this unit in residential new construction marketrequire the outdoor unit, indoor unit, refrigerant tubing sets,metering device, and filter drier listed in presale literature. Therecan be no deviation. Consult the Application Guideline andService Manual – Air Conditioners and Heat Pumps Using PuronRefrigerant to obtain required unit changes for specific applicationsand for R--22 retrofit.Check Equipment and Job SiteUnpack UnitMove to final location. Remove carton taking care not to damageunit.Inspect EquipmentFile claim with shipping company prior to installation if shipmentis damaged or incomplete. Locate unit rating plate on unit cornerpanel. It contains information needed to properly install unit.Check rating plate to be sure unit matches job specifications.Install on a Solid, Level Mounting PadIf conditions or local codes require the unit be attached to pad, tiedown bolts should be used and fastened through knockoutsprovided in unit base pan. Refer to unit mounting pattern in Fig. 2to determine base pan size and knockout hole location.For hurricane tie downs, contact distributor for details and PECertified (Professional Engineer), if required.On rooftop applications, mount on level platform or frame. Placeunit above a load--bearing wall and isolate unit and tubing setConsult local codes governing rooftop applications.Roof mounted units exposed to winds above 5 mph may requirewind baffles. Consult the Application Guideline and ServiceManual -- Residential Split System Air Conditioners and HeatPumps Using Puron Refrigerant for wind baffle construction.UNIT BASE PANDIMENSIONSin.

(9.53mm/m) per compressor manufacturer specifications.Clearance RequirementsWhen installing, allow sufficient space for airflow clearance,wiring, refrigerant piping, and service. Allow 24 in. (610 mm)clearance to service end of unit and 48 in. (1219.2 mm) above unit.For proper airflow, a 6 in. (152.4 mm) clearance on 1 side of unitand 12 in. (304.8 mm) on all remaining sides must be maintained.Maintain a distance of 24 in. (609.6 mm) between units. Positionso water, snow, or ice from roof or eaves cannot fall directly onunit.24ANA
