Contents

2INTRODUCTIONThese instructions describe installation, start-up, and serv-ice of 09DK020-044 air-cooled condensers (Fig. 1). SeeTable 1 for general unit physical data.INSTALLATIONStep 1 — Complete Pre-Installation Checks —Examine for damage incurred during shipment. File claimimmediately with transit company if damage is found. Verifythat the nameplate electrical requirements match the availablepower supply. Check the shipment for completeness.Step 2 — Locate and Rig Unit, Remove Ship-ping SkidLOCATION — If roof installation is specified, make certainthat roof structure can support the condenser weight. Refer toTable 1.Locate condenser where an adequate supply of inlet outdoorair is available. Do not locate where the possibility of air recir-culation exists, such as under a roof overhang.Locate condenser in an area free from airborne dirt or otherforeign material which could clog condenser coils.RIGGING — Preferred method is with spreader bars fromabove the unit. Use 2-in. (50 mm) OD pipe or hooks in liftingholes. Rig with 4 cables and spreader bars. All panels must bein place when rigging. See rigging label on unit for details con-cerning shipping weights, distance between lifting holes, cen-ter of gravity, and spreader bar dimensions. Also see Fig. 2.If overhead rigging is not possible, place unit on skid or padfor rolling or dragging. When rolling, use minimum of 3 roll-ers. When dragging, pull the pad. Do not apply force to theunit. When in final position, raise from above to lift unit offpad.PLACING UNIT — There must be 4 ft (1.22 m) for serviceand for unrestricted airflow on all sides of unit, and a minimumof 8 ft (2.44 m) clean air space above units. See Fig. 3, 4, and5. For multiple units, allow 8 ft (2.44 m) separation betweenunits for airflow and service.MOUNTING UNIT — When unit is in proper location, usemounting holes in base rails for securing unit to supportingstructure. Fasteners for mounting unit must be field supplied. Ifunit is to be mounted on vibration isolators, drill mountingholes in bottom of base rail at support points 1-4 (shown inFig. 3, 4, and 5) and locate isolators at those points.Table 1 — Physical Data — 50 and 60 HzFig. 1 — Model 09DK (Size 028 Shown)All panels must be in place when rigging. Do not forkliftunit if no skid is supplied. If unit has skid, use forklift truckfrom sides only.Fig. 2 — Rigging with Spreader Bars(Field Supplied)UNIT09DKMAX.
