3003 W CASINO RD BLDG 40-53 2020-10-22

• Boein 40-31 Phase 1 Jul 12,2012 drain pan shall include downspo direct condensate to the primary drain p he outlet shall be located at the � lowest point of the pan and shall be sufficient diameter to preclude drain pan overflow under any normally expected operating condition. Water Coils(UW, UU, UA,W, 5W, 5A,WD,5D, D1, D2, P,or TT) The coils shall have aluminum fins and seamless copper tubes. Copper fins may be applied to coils with 5/8-inch tubes. Fins shall have collars drawn,belled, and firmly bonded to tubes by mechanical expansion of the tubes.The coil casing may be galvanized or stainless steel. Refer to the Product Data section of the submittal for the coil casing material. The coils shall be proof-tested to 300 psig and leak-tested under water to 200 psig. Coil performance data and coils containing water or ethylene glycol shall be certified in accordance with AHRI Standard 410. Propylene glycol and calcium chloride, or mixtures thereof, are outside the scope of AHRI Standard 410 and, therefore, do not require AHRI 410 rating or certification. Headers are constructed of round copper pipe or cast iron. Tubes are 5/8"[16mm]OD 0.020"[0.508 mm]thick copper. ACCESS/INSPECTION/TURNING SECTION A section shall be provided to allow additional access/inspection of unit components and space for field-installed components as needed. An access door shall be provided for easy access. All access sections shall be complete with a double-wall, removable door downstream for inspection,cleaning,and maintenance. Interior and exterior door panels shall be of the same construction as the interior and exterior wall panels, respectively. All doors downstream of cooling coils.shall be provided with a thermal break construction of door panel and door frame. BELT-DRIVE PLENUM FAN SECTION The fan type shall be provided as required for stable operation and optimum energy efficiency. The fan shall be a single-width, single-inlet, multiblade-type, belt-driven plenum fan. The fan blades shall be backward-inclined airfoiL Plenum fans shall be equipped with self-aligning,antifriction, pillow-block bearings with an L-50 life of 200,000 hours as calculated per ANSI/AFBMA Standard 9. For any bearing requiring relubrication, the grease line shall be extended to the fan support bracket on the drive side. The fan shall be statically and dynamically balanced at the factory as a complete fan assembly(fan wheel, motor, drive, and belts).The fan shaft shall not exceed 75 percent of its first critical speed at any cataloged speed. Fan wheels shall be keyed to the fan shaft to prevent slipping. The fan shafts shall be solid steel. The fan section shall be provided with an access door on the drive side of the fan. Fans that are selected with inverter balancing shall first be dynamically balanced at design RPM.The fans then will be checked in the factory from 25%to 100% of design RPM to insure they are operating within vibration tolerance specifications,and that there are no resonant frequency issues throughout this operating range. Inverter balancing that requires lockout frequencies inputted into a variable frequency drive to in order to bypass resonant frequencies shall not be acceptable. If supplied in this manner by the unit manufacturer, the contractor will be responsible for rebalancing in the field after unit installation. Fans selected with inverter balancing shall have a maintenance free, circumferential conductive micro fiber shaft grounding ring installed on the fan motor to discharge shaft currents to ground. Motor Frame The motor shall be mounted integral to the isolated fan assembly and furnished by the unit manufacturer. The motor is mounted inside the unit casing on an adjustable base to permit adjustment of drive belt tension(not applicable for direct drive plenum fans). The motor shall meet or exceed all NEMA Standards Publication MG 1 requirements and comply with NEMA Premium efficiency levels when applicable except for fractional horsepower motors which are not covered by the NEMA classification. The motor shall be T-frame, squirrel cage with size,type, and electrical charaeteristics as � shown on the equipment schedule. Refer to the Product Data section for selected fan motors within each unit. Two-Inch Spring Isolators The fan and motor assembly(on sizes 10 to 120)shall be internally isolated from the unit casing with 2-inch (50.8 mm) deflection spring isolators,furnished and installed by the unit manufacturer.The isolation system shall be designed to resist loads produced by external forces, such as earthquakes, and conform to the current IBC seismic requirements. Fans sections with plenum fans shall be provided with an expanded-metal guard screen for the access door, mounted on the door opening,to deter unauthorized entry and incidental contact with rotating components. Refer to the Product Data section for fans with access door guards. FLD=Furnished by Trane U.S.Inc.dba Trane/ Equipment Submittal Page 8 of 26 Mstalled by Others
