Coordinate and provide all duct transitions required for final equipment connections to furnished equipment. Field verify and coordinate all duct dimensions before fabrication. The locations of all items shpwn on the drawings or called for in the specificatians that are not definitely fixed by dimensions are approximate only. The exact locations necessary ta secure the best conditions and results must be determined by the project site conditions and shall have the approval ot the Engineer before being installed. Do not scale drawings. All miscellaneous steel required to ensure proper installation and/or as shown in detai[s for piping, duchvork, and equipment shal[ be furnished and installed by the Mechanical Contractor. Provide access pane[s for installation in wa[Is and ceilings, where required, to service dampers, valves, smoke detectors, and other concealed mechanical equipment. Access panels shall be fumed over to General Contractor for installation. All equipment, piping, duchvork, etc., shall be supported as detailed, specified, andlor required to provide a vibration free installetion. All duchvork, piping, and equipment supported from structural steel shal! be coordinated with the General Contractor. A!! attachments to steel bar joists, trusses, or joist girders shall be at the upper member. Provide beam clamps meeting MSS standards. Welding ta structura! members shal! not be permitted. The use oi c-clamps sha!! not be permitted. Mechanical equipment, ductwork, and piping shall not be supported irom metal deck. Locations and sizes of all floor, wall, and roof openings shal! be croordinated with al! pther trades. Ai! air conditioning condensate drain lines from each air handling unit or roottop unit shall be piped Sul! size oi the unit drain outlat, with "P" trap, and piped to the nearest drain or rooi deck. See details shawn on the drawings or the contract spedficatiorts for depth oi air conditioning condensatetraps. Refer to typical details Sor iiuctwork, piping, and equipment installation. All valves, coils, dampers, etc. Shall be installed allowing easy access to them. Areas adjacent to the access panels shall be clear oi obstruciion. Fumish and instal! all equipment and material required to complete the installation as shown on the drawings. Equipment sizes and service space requirements may vary between different Martufacturers. Consult approved Manufacturer drawings as submitted and coordinate with these drawings. All air handling units shall operake without moisture carryover. Locate all mechanical equipment (fan coil units, unit heakers, unit ventilators, etc.} for unobstructed access ko unit access panels, controls, and valving. Refer to mechanical details for addi6onal equipment requirements. HVAC/SHEETMETAL: Certain items such as rises and drops in ductwork, access doors, volume dampers, etc., are indicated on the contr�.ct document drawings for clarity for a specific location requirement and shall not be interpreted as the extent of the requirements for these items. All ductwork dimensions, as shown on the drawings, are internal clear dimensions. Keep all ductwork, duct system and equipment openings covered with adhesive duc4 protective wrap like VentureTape 9592, until system start-up. This is to prevent intrusion of construction dirt and debris into the duct system, and HVAC equipment Provide flexible connections in all duchvork systems lsupply, return, and exhaust) connected to air handling units, fans, and other equipment which require vibration isolation. Flexible connections shall be provided at the point of connection to the equipment unless otherwise noted. Unless otherwise noted, all duchvork is overhead, tight to the underside of ths structure, with space for insulation and below any required piping. Runs of flexible duct shall not exceed 5'-0".

Instail horizontal refrigerant hot gas discharge piping with %" per 10 feet downward slope away from the compressor. Install horizontal refrigerant suction lines with Ya" per 10 feet downward slope to the compressor, with no long traps or dead ends which may cause oil to separate from the suctipn gas and return to the compressor in damaging slugs. Insulate all interior linesets with 2' thick, flexible elastomeric insulation. Ins�late exterior finesets with 1" thick flex{ble elastomeric insulation with external .020" aluminum protective jacket. APPEAF�ANCE: All equipment should be installed with great regard to a neat ftnished product Whenever possible, wiring should be routed in such a way as to minimize visibiliqy. . Piping should be tight to structure whenever possible, and orthogonal. Eliminate the need for condensate pumps if possible.
