2The outdoor unit contains system refrigerant charge for operationwith AHRI 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.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.INSTALLATIONCUT HAZARDFailure to follow this caution may result in personal injury.Sheet metal parts may have sharp edges or burrs. Use care andwear appropriate protective clothing and gloves whenhandling parts.CAUTION!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.This unit employs one louver spacer on each of the four sides toprevent louver movement during operation. The louver spacers aretrapped between the coil surface and louver at the approximatecenter of each side (See Fig. 2). This louver spacer should bepresent and, if dislodged during shipment, must be reinstalledbefore unit is placed into operation.A11380aFig. 2 -- Louver Spacer LocationInstall 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. 3to determine base pan size and knockout hole location.For hurricane tie downs, contact local distributor for details and PE(Professional Engineer) certification, if required by localauthorities.On rooftop applications, mount on level platform or frame. Placeunit above a load--bearing wall and isolate unit and tubing set fromstructure. Arrange supporting members to adequately support unitand minimize transmission of vibration to building. Consult localcodes governing rooftop applications.Roof mounted units exposed to winds may require wind baffles.Consult the Application Guideline and Service Manual --Residential Split System Air Conditioners and Heat Pumps forwind baffle construction.NOTE: Unit must be level to within 2_ (3/8 in./ft,9.5 mm/m.)per compressor manufacturer specifications.3/8--- in.

Allow 24 in. (609.6 mm)clearance to service end of unit and 48 in. (1219.2 mm) (aboveunit. For proper airflow, a 6--in. (152.4 mm) clearance on 1 side ofunit and 12--in. (304.8 mm) on all remaining sides must bemaintained. Maintain a distance of 24 in. (609.6 mm) betweenunits. Position so water, snow, or ice from roof or eaves cannot falldirectly on unit.On rooftop applications, locate unit at least 6 in. (152.4 mm) aboveroof surface.Operating AmbientThe minimum outdoor operating ambient in cooling mode is 55_F(12.78_C) without low ambient cooling enabled in the InfinityControl, and the maximum outdoor operating ambient in coolingmode is 125_F (51.67_C). At line voltage of 208v (or below, andoutdoor ambient of 120_F (48.9_C) (and above), the compressoroperates in low stage. Low ambient cooling operation is possibleat ambient as low as 0_F (--17.78_C) using UI Infinity controlledlow ambient on 17 and 21 SEER models and low ambientaccessory kits on 17 SEER models..24ANB7 / 24ANB1
