UNLESS SPECIFICALLY NOTED OR SHOWN

OTHERWISE.

E.T.R.

MECHANICAL GENERAL PROJECT NOTES:

FOR GENERAL DUCT CONSTRUCTION SEE DETAILS ON MECHANICAL DETAILS SHEET.

ALL WORK SHALL BE IN ACCORDANCE WITH THE BEST QUALITY STANDARDS OF THE

TRADE, AND SHALL CONFORM WITH ALL FEDERAL, STATE, AND LOCAL CODES AND

STANDARDS.

CONSTRUCTION DOCUMENTS SHALL BE FOLLOWED AS CLOSELY AS POSSIBLE,

HOWEVER, SYSTEMS HAVE BEEN SHOWN DIAGRAMMATICALLY AND IN SOME CASES,

ENLARGED FOR CLARITY. ANY OFFSETS, ADDITIONAL FITTINGS, AND/OR

APPURTENANCES REQUIRED TO PROVIDE A COMPLETE AND COORDINATED SYSTEM

SHALL BE BORNE BY THE CONTRACTOR.

REFER TO ARCHITECTURAL REFLECTED CEILING PLANS FOR EXACT LOCATION OF

CEILING MOUNTED MATERIALS INCLUDING ALL DIFFUSERS, GRILLES, AND REGISTERS.

THE H.C. SHALL COORDINATE DUCTWORK INSTALLATIONS WITH OTHER TRADES.

LIGHTING AND DUCTWORK DESIGNS INDICATED ON CONTRACT DRAWINGS WERE

COORDINATED, HOWEVER CONFLICTS WITH DUCTWORK AND LIGHTS MAY ARISE DUE TO

GRID INSTALLATION. H.C. SHALL BE RESPONSIBLE FOR ALL DUCTWORK MODIFICATIONS

AND OFFSETS REQUIRED TO AVOID FIELD CONDITIONS.

BALANCE DAMPERS SHALL BE LOCATED AT BRANCH CONNECTION TO THE MAIN.

FLEXIBLE DUCTWORK IS LIMITED TO A MAXIMUM LENGTH OF 3 FEET, WITH NO DIPS,

SAGS, OR TIGHT ELBOWS; AND ON SUPPLY DUCTWORK ONLY. FLEXIBLE DUCTWORK

SHALL BE AN INSULATED, SEMI-RIGID AND LIGHT WEIGHT AIR DUCT, MANUFACTURED

BY USING DEAD SOFT ALUMINUM STRIP WHICH IS SPIRALLY WOUND AND

MECHANICALLY JOINED TOGETHER FORMING AN AIR TIGHT-LEAKPROOF TRIPLE LOCK

SEAM. DUCT TO BE SELF-SUPPORTING AND CORROSIVE RESISTANT UL-181 CLASS I

PRODUCT, WITH A POLYETHYLENE VAPOR BARRIER. FLEXIBLE DUCTWORK TO BE LIKE

MASTERFIT UPC-018 (ACOUSTICAL) OR AN APPROVED EQUAL.

PROVIDE NECK PLENUMS ON RETURN AND EXHAUST GRILLES AS REQUIRED. SEE

DETAILS.

PROVIDE TURNING VANES IN ALL SQUARE ELBOWS. SEE DETAILS.

ALL EQUIPMENT INCLUDING BUT NOT LIMITED TO DUCTWORK, PIPING, UNIT HEATERS,

ETC. SHALL BE HUNG FROM THE TOP CHORD OF THE STRUCTURAL STEEL.

EACH MAIN DUCT PASSING THROUGH FLOOR SPACES SHALL BE FIRE DAMPERED.

ALL EXTERIOR PENETRATIONS SHALL BE WEATHER AND WATER TIGHT.

CONTRACTORS ARE TO REVIEW EXISTING STRUCTURAL AND PLANS, WITH ACTUAL

LAYOUT OF BEAMS, JOISTS, ETC. TO AVOID CONFLICT BETWEEN DUCT. ADJUST DUCT

ROUTING TO ACCEPT STRUCTURAL CONDITIONS.

ALL EXHAUST DISCHARGES AND GAS FLUES WHERE INDICATED SHALL BE LOCATED A

MINIMUM OF 25'-0" AWAY FROM OUTSIDE AND COMBUSTION AIR INTAKES UNLESS LOCAL

AND STATE CODES MANDATE ADDITIONAL DISTANCE.

CONTRACTOR SHALL VERIFY ELECTRICAL CHARACTERISTICS OF ALL MECHANICAL

EQUIPMENT WITH THE ELECTRICAL CONTRACTOR PRIOR TO STARTING WORK.

WHERE WALL TYPE LOUVERS ARE INDICATED, MECHANICAL CONTRACTOR SHALL SEAL

WATER-TIGHT ALL AROUND LOUVER WITH SILICON CAULKING. CONTRACTOR SHALL

COORDINATE PAINTING REQUIREMENTS FOR LOUVERS WITH GENERAL CONTRACTOR

PRIOR TO SUBMITTING BID.

RIGID STRAIGHT TERMINAL UNIT INLET LENGTH SHALL BE A

MINIMUM OF 3 TIMES THE DIAMETER OF INLET

A FLEXIBLE AIR DUCT CONNECTOR IS NOT MANDATORY FOR INLET TO

THIS BOX, BUT ALLOWED TO ACCOMMODATE MINOR OFFSETS. MAXIMUM

LENGTH 3'-0" [900mm].

A BRANCH DUCT SERVING AN INDIVIDUAL BOX MAY BE THE SAME SIZE

AS THE BOX INLET, PROVIDED THE EQUIVALENT LENGTH OF THE

BRANCH DUCT, AS SHOWN, DOES NOT EXCEED 10 FEET (3 METERS).

FOR LONGER LENGTHS, INCREASE THE DUCT SIZE AND PROVIDE A

DUCT TRANSITION TO MAINTAIN THE DUCT STATIC PRESSURE DROP AT

OR BELOW 0.2"/100' [1.64Pa/m].

FLEXIBLE AIR DUCT CONNECTORS, WHEN USED FROM TERMINAL UNIT

SUPPLY AIR DUCT TO DIFFUSER, SHALL NOT EXCEED 5'-0"

[1500mm]. USE RIGID ELBOWS FOR CHANGE OF DIRECTION GREATER

THAN 45°.

COMPONENT ARRANGEMENT MAY VARY BY MANUFACTURER. PROVIDE

INSULATION W/VAPOR BARRIER FOR CONNECTING DUCT SECTIONS.

USE OF THE FLEXIBLE AIR DUCT CONNECTORS ARE NOT PERMITTED

FOR THE DEDICATED AHU SERVING THE SURGICAL SUITE.

A VERTICAL DAMPER IS SHOWN. HORIZONTAL DAMPER INSTALLATION, IS SIMILAR.

FOLLOW DAMPER MANUFACTURER'S INSTRUCTIONS, INCLUDING FASTENER OPTIONS AND

GAGES FOR SLEEVE AND PERIMETER ANGLES. FIRE DAMPERS MUST BE INSTALLED IN

THE PARTITION OR FLOOR AND NOT OUTSIDE THE PENETRATION.

GALVANIZED SLEEVE: GAGE NOT LESS THAN CONNECTING DUCT. FASTEN SLEEVE TO

DAMPER FRAME AND TO PERIMETER ANGLES.

PERIMETER ANGLES: GALVANIZED STEEL, NOT LESS THAN 1-1/2"x1-1/2" [40x40mm], 14 GAGE, TO PROVIDE 1" [25mm] MINIMUM OVERLAP OF OPENING ON ALL 4 SIDES.

BREAKAWAY DUCT CONNECTION: CONTRACTOR'S OPTION OF TYPES SHOWN IN SMACNA.

ACCESS PANELS: SIZE AND LOCATION TO PERMIT SERVICING THE FUSIBLE LINK OR

LINKS.

PROVIDE 1/4" TO 1/2" [6 TO 15mm] CLEARANCE ON HEIGHT AND WIDTH.

FILL OPEN SPACE WITH ROCK WOOL FIRESTOP FIBER.

ALL DUCT WORK RISERS WHICH ARE RUN EXPOSED, SUCH AS THRU ATTIC FLOORS

AND MECHANICAL ROOM FLOORS, SHALL BE PROVIDED WITH 3" [75mm] HIGH

CONCRETE CURB AROUND OPENING FOR DUCT.

ALL VANE ELBOWS SHALL BE CONSTRUCTED AND INSTALLED AS DETAILED BY

SMACNA.

WHEN W1 DOES NOT EQUAL W2, VANE SHALL BE SINGLE THICKNESS VANE TYPE

REGARDLESS OF W DIMENSION.

ALL SINGLE THICKNESS VANES SHALL HAVE A 2" [50mm] RADIUS, 1 1/2" [40mm] MAXIMUM SPACE BETWEEN VANES AND A 3/4" [20mm] TRAILING EDGE.

WHEN W EQUALS W2 AND W1 IS GREATER THAN 20" [500mm] VANES SHALL BE

DOUBLE VANE TYPE.
