These units must be installed in accordance with the currentedition of the following national and local safety codes:In U.S.A.:1. National Electrical Code ANSI/NFPA No. 70.2. Local electric utility requirements.In Canada:1. Canadian Electrical Code C22.12. Canadian Installation Codes CAN/CGA-B149.1 and .2.Refer to Table 1 for Unit Application Data.If components are to be added to a unit to meet local codes, theyare to be installed at the dealer’s and / or the customer’s expense.Size of unit for proposed installation should be based on heatloss / heat gain calculation made according to the methods ofAir Conditioning Contractors of America (ACCA).LOCATIONUse the following guidelines to select a suitable location forthese units.1. Unit is designed for outdoor installation only.2. Outdoor coil must have an unlimited supply of air.3. For ground level installation, a level pad or slab should beused. The thickness and size of the pad or slab used shouldmeet local codes and unit weight. Do not tie the slab to thebuilding foundation.4. Roof structures must be able to support the weight of the unitand its options and / or accessories. Unit must be installed ona solid level roof curb or appropriate angle iron frame.CAUTION: If a unit is to be installed on a roof curb or special frameother than a YORK roof curb, gasketing must be applied toall surfaces that come in contact with the unit underside.5. Maintain level tolerance to 1/2" maximum across the entirelength or width of the unit.6. Elevate the unit sufficiently to prevent any blockage of theair entrances by snow in areas where there will be snowaccumulation. Check the local weather bureau for the ex-pected snow accumulation in your area.OUTDOOR COIL CONDENSATE DRAINAGE PRECAUTIONCondensate will drain from the outdoor coil during the heatingand defrost cycles. Normally this condensate may be allowedto drain directly onto the ground/roof. A gravel bed isrecommended to prevent mud splashing.WARNING: The unit should not be installed in an area where mudor ice could cause personal injury. Remember thatcondensate will drip from the outdoor coil during heatand defrost cycles and that this condensate will freezewhen the temperature of the outdoor air is below 32°F.RIGGING AND HANDLINGExercise care when moving the unit. Do not remove anypackaging until the unit is near the place of installation. Rig theunit by attaching chain or cable slings to the lifting holesprovided in the base rails. Spreaders, whose length exceedsthe largest dimension across the unit, MUST be used acrossthe top of the unit.BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHTIS DISTRIBUTED EQUALLY ON THE CABLES SO THAT ITWILL LIFT EVENLY.Units may also be moved or lifted with a forklift. Slottedopenings in the base rails are provided for this purpose.LENGTH OF FORKS MUST BE A MINIMUM OF 42".Remove the nesting brackets from the four corners on top ofthe unit. All screws that are removed when taking thesebrackets off must be replaced on the unit.Refer to Table 3 for unit weights and to Figure 1 for approximatecenter of gravity.CLEARANCESAll units require certain clearances for proper operation andservice. Refer to Figure 6 for the clearances required forcombustible construction, servicing, and proper unit operation.WARNING: Do not permit overhanging structures or shrubs toobstruct outdoor air discharge outlet.DUCTWORKDuctwork should be designed and sized according to themethods in Manual Q of the Air Conditioning Contractors ofAmerica (ACCA).A closed return duct system shall be used. This shall notpreclude use of economizers or outdoor fresh air intake. Thesupply and return air duct connections at the unit should bemade with flexible joints to minimize the transmission of noise.The supply and return air duct systems should be designed forthe CFM and static requirements of the job. They should NOTbe sized to match the dimensions of the duct connections onthe unit.CAUTION: When fastening ductwork to the side duct flangeson the unit, insert the screws through the ductflanges only. DO NOT insert the screws through theINSTALLATIONVoltage VariationMin. / Max.*208/230V 187 / 253460V 414 / 506575V 518 / 630CoolingWet Bulb Temperature (°F) of Airon Indoor Coil, Min. / Max. 57 / 72Dry Bulb Temperature (°F) of Airon Outdoor Coil, Min. / Max. 45 / 120Heating Minimum Dry Bulb Temperature(°F) of Air on Outdoor Coil -10*Rated in accordance with ARI Standard 110, utilization range "A".TABLE 1 - UNIT APPLICATION DATA821⁄4“403⁄4“447⁄8“ 193⁄4“APPROXINATECENTER OFGRAVITYFRONTFIG. 1 - CENTER OF GRAVITY511.06-N5YUnitary Products Group 3
