1. THIS PROJECT IS DESIGNED BASED ON THE FOLLOWING CODES: INTERNATIONAL MECHANICAL CODE 2018, INTERNATIONAL ENERGY CONSERVATION CODE 2015, ASHRAE 62.1, ASHRAE 90.1-2016, ASHRAE 15, UFC 1-200-01, UFC

3-410-01, AND UFC 1-200-02.

2. ALL INFORMATION REQUIRED FOR DESIGN MAY NOT BE COVERED IN THE DRAWINGS. REFER TO DIVISION 23 TECHNICAL

SPECIFICATIONS AND OTHER RELATED SECTIONS FOR ADDITIONAL INFORMATION.

3. ALL DUCT SIZES SHOWN ON THE DRAWINGS ARE NET INSIDE CLEAR DIMENSIONS.

4. UTILIZE LONG RADIUS ELBOWS WHERE SPACE PERMITS UNLESS OTHERWISE NOTED. ALL RECTANGULAR ELBOWS SHALL

CONTAIN TURNING VANES.

5. COORDINATE WITH OTHER UTILITIES TO AVOID INTERFERENCES WHEN INSTALLING DUCTWORK, PIPING AND

EQUIPMENT.

6. FURNISH AND INSTALL ALL EQUIPMENT AS PER MANUFACTURER'S RECOMMENDATIONS AND INSTRUCTIONS. PROVIDE

MODIFICATIONS AND ACCESSORIES AS REQUIRED AND RECOMMENDED BY THE MANUFACTURER TO ASSURE PROPER

OPERATION OF THE EQUIPMENT.

7. VERIFY DIMENSIONS, LOCATIONS, ELEVATIONS AND CONFIGURATION OF ALL ITEMS ASSOCIATED WITH THE

INSTALLATION OF DUCTWORK AND EQUIPMENT.

8. EQUIPMENT, DUCTWORK AND PIPING SHALL NOT BE SUPPORTED OR SECURED TO OTHER EQUIPMENT, DUCTWORK, PIPING OR OTHER UTILITIES.

9. PAINT ALL EQUIPMENT VISIBLE THRU AIR DEVICES MATT BLACK.

10. PROVIDE MANUAL VOLUME DAMPERS IN ALL DUCTWORK AT ALL DUCT SPLITS, BRANCH RUNOUTS AND DUCT COLLARS

FOR REGISTERS. ALL MANUAL DAMPERS MAY NOT BE SHOWN ON DRAWINGS.

11. ALL DUCTWORK SHALL BE CONSTRUCTED, SEALED AND INSTALLED IN CONFORMANCE TO SMACNA DUCT

CONSTRUCTION STANDARDS.

12. TO RESOLVE FIELD PROBLEMS IN ROUTING DUCTWORK THE CONTRACTOR SHALL USE THE SAME CIRCULAR EQUIVALENT

DIAMETER TO TRANSFORM DUCT SIZE FROM THAT SPECIFIED ON THE DRAWINGS.

13. PROVIDE FIRE RESISTANT FLEXIBLE CONNECTION WHENEVER DUCTWORK IS CONNECTED TO MOTORIZED EQUIPMENT.

14. DUCT MATERIAL SHALL BE ZINC-COATED STEEL WITH METAL AND GALVANIZING THICKNESS AS PER SMACNA

CONSTRUCTION STANDARDS.

15. PROVIDE OSHA-REQUIRED CLEARANCES AROUND ALL HVAC EQUIPMENT AND COMPONENTS FOR PERSONNEL ACCESS

AND MAINTENANCE.

16. ALL PIPE HANGERS AND SUPPORTS SHALL COMPLY WITH MANUFACTURER'S STANDARDIZATION SOCIETY (MSS)

STANDARDS. VERTICAL PIPES MUST BE SUPPORTED AT EACH FLOOR WITH PIPE CLAMPS.

17. INSULATE BACKS AND PLENUMS OF SUPPLY AIR DEVICES WITH MINIMUM 1" MINERAL FIBER.

18. ALL AIR MOVING EQUIPMENT CONTAINING PARTICULATE FILTERS SHALL NOT BE OPERATED WITHOUT PARTICULATE

FILTERS IN PLACE.

19. ADD DIELECTRIC CONNECTIONS BETWEEN PIPES OF DIFFERENT METALS.

20. MAINTAIN A VERTICAL SLOPE OF 1/8" PER FOOT IN THE DIRECTION OF FLOW FOR ALL HORIZONTAL CONDENSATE

PIPING.

21. INSTALL ALL PIPING PARALLEL TO BUILDING LINES UNLESS STATED OTHERWISE IN DRAWINGS.

22. ALL ABOVE CEILING EQUIPMENT, DUCTWORK AND PIPING AND ASSOCIATED DEVICES (VALVES, DAMPERS, ETC.) SHALL

BE SUPPORTED FROM DECK AND SHALL BE ACCESSIBLE BY A 5' TALL PERSON STANDING ON A LADDER.

23. PROVIDE MERV 8 FILTERS DURING CONSTRUCTION. REPLACE WITH NEW FILTERS AT SUBSTANTIAL COMPLETION. NEW

FILTERS SHALL BE AS PER SCHEDULE.

24. ALL PIPING PENETRATIONS THROUGH FIRE RATED WALLS SHALL BE SEALED WITH FIRE CAULKING ON BOTH SIDES OF THE

PIPE.

25. ALL EMERGENCY SHUTDOWN BUTTONS THROUGHOUT THE BUILD SHALL BE PROVIDED WITH A CLEAR, NON-LOCKABLE, PLASTIC COVER. INSTALL AT 48" AFF. CONTRACTOR TO FIELD VERIFY TO AVOID CONFLICTS WITH EXISTING AND

PROPOSED FURNITURE, FIXTURES, AND EQUIPMENT.

26. REFER TO TECHNICAL SPECIFICATION 23 07 00 FOR INSULATION TYPE AND THICKNESS FOR MECHANICAL SYSTEMS.

27. ROUTE INSULATED PIPING TIGHT AGAINST CEILING STRUCTURE AND WRAP PIPING BELOW BEAMS. CONCEAL PIPING

ABOVE SUSPENDED CEILINGS TO EXTENT POSSIBLE. DO NOT ROUTE PIPING ABOVE ELECTRICAL OR

TELECOMMUNICATION ROOMS UNLESS IT IS SLEEVED. COORDINATE PIPING LAYOUT WITH OTHER TRADES SUCH AS

DUCTWORK. LIGHTING, ELECTRICAL, FIRE PROTECTION AND BUILDING CONTROLS. PROVIDE SHOP DRAWINGS TO

CLEARLY SHOW PIPING ROUTING AND COORDINATION WITH OTHER ELEMENTS. IN CASE OF CONFLICT, COORDINATE

REROUTING OF UTILITIES WITH ENGINEER AND ARCHITECT.

28. PROVIDE LINE SIZE MANUAL ISOLATION VALVES AT ALL MAJOR PIPING TAKE OFFS. REFER TO PIPING SCHEMATIC FOR

VALVE LOCATION AND SIZES. INSTALL ISOLATION VALVES IN ACCESSIBLE LOCATIONS. PROVIDE ADEQUATELY SIZED

ACCESS DOORS WHERE REQUIRED.

29. PROVIDE DRAIN AND VENT CONNECTIONS AT LOWEST AND HIGHEST POINTS OF CHILLED WATER PIPING SEGMENTS.

30. FOR AIR HANDLING UNITS OVER 2000 CFM, PROVIDE SMOKE DETECTORS IN THE SUPPLY AIR DUCT UPSTREAM OF ANY

BRANCH CONNECTIONS AND IN THE RETURN AIR DUCT UPSTREAM OF FILTERS AND OUTSIDE AIR CONNECTION. DUCT

SMOKE DETECTORS SHALL SHUT DOWN UNIT UPON ACTIVATION AND SIGNAL ALARM TO FIRE ALARM PANEL.

CONTRACTOR TO COORDINATE WITH OWNER’S REPRESENTATIVE FOR FIRE ALARM SYSTEM INFORMATION. FOR

DUCTLESS SYSTEMS SUPPLYING OVER 2000 CFM, THE UNIT SHALL SHUT DOWN UPON ACTIVATION OF THE ROOM

SMOKE DETECTOR. SMOKE DETECTORS SHALL BE FURNISHED AND WIRED BY THE FIRE ALARM CONTRACTOR. THE

MECHANICAL CONTRACTOR SHALL BE RESPONSIBLE FOR MOUNTING THE SMOKE DETECTOR IN DUCTWORK IN

ACCORDANCE WITH THE MANUFACTURE’S PRINTED INSTRUCTIONS. COMPLY WITH NFPA 72.
