Anleitung Zusammenfassung
File claim with transportation agency. Do not drop unit. Keep unit upright. Units are designed to be hoisted only. However, units with optional shipping skids may be moved with a fork truck. Use spreader bars over unit to prevent sling or cable damage to unit. Level unit by using unit frame as reference. Leveling tolerance is ±1/16 in. per linear ft in any direction. See Fig. 1 for additional information. Unit weight is shown in Table 1. Roof Curb — Assemble and install accessory roof curb in accordance with instructions shipped with accessory. (In areas of prolonged sub-freezing temperatures or heavy snowfall, the use of an 18-in. high roof curb is recommended. This permits proper drainage during defrost.) Refer to Fig. 2. Install insulation, cant strips, roofing and flashing as required. Ductwork can be installed to roof curb COMPRESSOR END DiMENSiONS (ft-m.î ïiNfT 1 A i 8 SCEÛ024 I Ô-W2 ■ 6-1 50HGC23 j 9-Ö } 8-0 5050034 | n-5 10-3 MOTES; t, A!i unit paneis must be in ptece when ng8»r»s 2.

Unit leveling tolerance is ±1/16 in. per linear ft in any direction. This is necessary to permit unit drain to function properly. Cut hole(s) in roof to accommodate return and supply ducts only. Refer to accessory installation instructions. Roof Mount — Check building codes for weight distribution requirements. Alternate Unit Support Methods — Where the preferred curb or slab mount cannot be used, support unit with sleepers along unit perimeter using unit curb-support areas. However, if sleepers cannot be used, support long sides of unit (dimension “A,” Fig. 3) by three 4-in. by 4-in. pads, equally spaced. Units may sag if supported by corners only. Positioning — Position unit so that drifting snow does not build up on outdoor coil. Provide clearances around and above the unit for airflow, safety, and service access (Fig. 3). Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air. Although unit is weatherproof, guard against water from higher runoff and overhangs. Field-Fabricated Ductwork — Secure all ducts to building structure. Use flexible duct connectors between unit and ducts as required. Insulate and weatherproof all external ductwork, joints and all roof openings with flashing and mastic in accordance with applicable codes. Ducts passing thru unconditioned spaces must be insulated and covered with a vapor barrier. Unit Duct Connections — Ductwork openings are shown in Fig. 3. Economizer Hood Installation, Fig. 4 — The economizer mechanism and allelectrical connections are factory installed and adjusted. The hood assembly, outdoor air inlet screens and required hardware are shipped separately and must be field installed. NOTE: There is a linkage rod and 3 fasteners (speed nuts) shipped with the economizer hood assembly. This rod is not required on 50EQ units. Install economizer hood(s) as follows: 1. Loosen unit top panel sheet metal screws above outdoor air inlet opening. 2. Assemble hood top panel, side panels and support channel. © Carrier Corporation 1979 Form 50EQ-4SI Table 1 — Physical Data UNIT MODEL 50EQ024 50EQ028 50EQ034 OPERATING WEIGHT (lb) Base Unit Base Unit with Economizer 3300 3450 3900 4075 4550 4750 COMPRESSOR No. .Model Oil (3GS or B1) pts (per Compr) Servie 2 06D824 10 eable, Reciprocating Her 2. 06D328 10 metic 2 06D537 ________10 _ __ 29.1 ...29.1 REFRIGERANT CHARGE Sys 1 *...Sys 2 (lb) R-22 20.0...21.3 R-22 23.5. .24.0 OUTDOOR AIR FANS No. ...Hp Frame (NEMA) Rpm (1-Phase) 2 . 1 56T 1050 ______ 7-V2 1-1/8 1-3/8 154T 213T 6 5 6 0 5 3 5 6 106 8 1073 991 1159 1225 1-3/16 2 3V750 2 3V670 1300 Direct Drive, Propeller 2.1 j 31 56T 56T 1050 I 1050 INDOOR AIR FANS * Std Motor 0pt Shaft Diam (in.) — RPM 1750 Std Motor Frame Size Qpt Motor Pulley Pitch Diam (in.)t q^' Fan Pulley Pitch Diam (in.)
