2DOMESTIC UNITS — Standard 38AP unit packaging con-sists of coil protection only. Skids are not provided. If overheadrigging is not available at the jobsite, place the unit on a skid orpad before dragging or rolling. When rolling, use a minimumof 3 rollers. When dragging, pull the pad or skid. Do not applyforce to the unit. When in final position, raise from above to liftunit off the pad or skid.EXPORT UNITS — All export units are mounted on skidswith vertical coil protection. Leave the unit on the skid until itis in final position. While on the skid, the unit can be rolled orskidded. Apply force to the skid, not to the unit. Use a mini-mum of 3 rollers when rolling. When in final position, raisefrom above to remove the skid.PLACING UNITS — When considering location of the unit,be sure to consult National Electrical Code (NEC, U.S.A.) andlocal code requirements. Allow sufficient space for airflow,wiring, piping, and service. The placement area must be leveland strong enough to support the operating weight of the unit.(See Table 5.) When unit is in proper location, use of mountingholes in base rails is recommended for securing unit tosupporting structure. For mounting unit on vibration isolators,4 x 24 in. perimeter support ASTM “C” channels between unitand the isolators are recommended with a minimum of 4 chan-nels per unit. Fasteners for mounting unit are field supplied.See Fig. 4.Refer to Fig. 5-8 for airflow clearances. Recommendedminimum clearances are 6 ft (1829 mm) for unrestricted air-flow and service on sides of unit, 4 ft (1219 mm) on ends, andunrestricted clear air space above the unit. Provide ample spaceto connect liquid and suction lines to indoor unit. For multipleunits, allow 10 ft (3048 mm) separation between airflowsurfaces. If walls surround the unit, wall height should not ex-ceed the top of the unit fan discharge. Installation in a pit is notrecommended.Refer to Fig. 9 for outdoor fan and compressor layout.Refer to Fig. 10 and 11 for unit piping installation. SeeTable 6 for refrigerant specialties part numbers.IMPORTANT: Be sure to mount unit level to ensureproper oil return to compressors.38AP D 025 6 4 A 1 0 0 5 038AP – Split System Condensing Unit Packaging/Security Options0 – Std Packaging8 – Std Packaging, Bottom SkidJ – Bottom Skid, Top Crate, BagControls/Communications Options2 – Scrolling Marquee3 – EMM, Scrolling Marquee5 – No DisplayAmbient/Capacity Control/Interrupt Options0 – Std Ambient, Std Compressor,Std Interrupt2 – Std Ambient, Digital Compressor,Std Interrupt3 – Std Ambient, Std Compressor,High Interrupt5 – Std Ambient, Digital Compressor,High Interrupt6 – Low Ambient, Std Compressor,Std Interrupt8 – Low Ambient, Digital Compressor,Std Interrupt9 – Low Ambient, Std Compressor,High InterruptC – Low Ambient, Digital Compressor,High InterruptLine Length Options1 – Standard Line Length2 – Long Line Length Check ValvesElectrical Options0 – Single Point Power, Terminal Block1 – Single Point Power,Non-Fused DisconnectRefrigeration Circuit Options*D – Dual Refrigeration CircuitS – Single Refrigeration CircuitRevision LevelA – Current Revision LevelylppuSrewoP1 – 575-3-602 – 380-3-605 – 280/230-3-606 – 460-3-609 – 380/415-3-50Condenser Coil/Low Sound Options4 – MCHX, No Sound Treatment5 – E-coat, MCHX, No Sound TreatmentC – MCHX, Low Sound Fan(s)D – E-coat MCHX, Low Sound Fan(s)H – MCHX, Low Sound Fan(s), Compressor BlanketsJ – E-coat MCHX, Low Sound Fan(s), Compressor BlanketsNominal Capacity – Tons (kW)025 – 25 (88) 050 – 50 (176) 090 – 90 (317)027 – 27 (95) 060 – 60 (211) 100 – 100 (352)030 – 30 (106) 070 – 70 (246)040 – 40 (141) 080 – 80 (281)LEGEND*38APS units available in sizes 025-050 only.EMM — Energy Management ModuleMCHX — Microchannel Heat Exchangera38-7100.epsFig. 1 — Model Number Nomenclature
