GENERAL HVAC NOTES

1. LOCATE EXHAUST OUTLETS OF VENTILATION SYSTEMS,

COMBUSTION EQUIPMENT STACKS, MEDICAL-SURGICAL

VACUUM SYSTEMS, & PLUMBING VENTS AT LEAST 10 FEET

FROM OUTDOOR AIR INTAKES.

2. INSTALL ALL EQUIPMENT, MATERIALS, AND ACCESSORIES PER

MANUFACTURERS WRITTEN INSTRUCTIONS.

3. BOTTOM OF EQUIPMENT ON ROOF SHALL BE A MINIMUM OF 12"

ABOVE ROOF MEMBRANE. CONTRACTOR SHALL COORDINATE

ASSOCIATED ROOF CURB HEIGHT AS REQUIRED.

4. ALL EXISTING SYSTEMS (INCLUDING EXHAUST FANS; AIR

HANDLING UNITS; PUMPS) THAT SERVES AREAS BEING

RENOVATED SHALL BE REBALANCED AS REQUIRED.

5. NOTIFY OWNER OF ANY PIPING OR DUCTWORK DEMOLITION

THAT MAY AFFECT NORMAL OPERATION OF OTHER AREAS.

6. FIELD VERIFY LOCATIONS OF EXISTING PIPING THAT MAY

CONFLICT WITH NEW CONSTRUCTION AND RELOCATE AS

NEEDED.

7. LOCATIONS OF THE THERMOSTATS TO BE VERIFIED IN FIELD.

8. PROVIDE BALANCE DAMPERS FOR EACH DIFFUSER/GRILLE

AND BRANCH DUCT.

9. PROVIDE FLEXIBLE DUCT IN ACCESSIBLE CEILINGS. 6 FT MAX

LENGTH. KEEP BENDS TO A MINIMUM.

10. ALL REHEAT COIL HS&R RUNOUT PIPES SHALL BE 3/4" UNLESS

OTHERWISE NOTED.

11. PROVIDE ACCESS PANELS ON EACH SIDE OF REHEAT COILS.

12. PROVIDE 5 FT MIN BEFORE ANY DUCT TAKEOFF FOR

DUCTWORK DOWNSTREAM OF VAV BOXES.

13. PROVIDE 1 1/2 DUCT DIAMETERS MIN. DUCT LENGTH OF HIGH

PRESSURE BRANCH DUCTWORK ON THE UPSTREAM SIDE OF

VAV BOXES.

14. CONTRACTOR SHALL COORDINATE ALL WORK WITH OTHER

DISCIPLINES PRIOR TO CONSTRUCTION TO AVOID CONFLICTS.

15. PROVIDE MANUAL AIR VENTS WITH 3/4" HOSE CONNECTION AT

ALL HIGH POINTS.

16. OFFSET PIPING TO ACCOMMODATE LARGE DUCTWORK.

17. THE CONTRACTOR SHALL FIELD VERIFY THE SIZES, LOCATION,

ELEVATIONS, AND DETAILS OF ALL EXISTING CONDITIONS THAT

MAY AFFECT THE WORK.

18. THE CONTRACTOR SHALL BE RESPONSIBLE FOR MAINTAINING

THE INTEGRITY OF ALL EQUIPMENT AND MATERIALS IN A "NEW"

CONDITION DURING CONSTRUCTION.

19. ALL WORK SHALL BE PERFORMED BY LICENSED

CONTRACTORS AND SUBCONTRACTORS AS REQUIRED BY LAW.

20. ALL WORK SHALL CONFORM TO MICHIGAN MECHANICAL CODE,

LATEST APPLICABLE EDITION.

21. CONTRACTOR SHALL USE LOW PRESSURE LOSS DUCT

FITTINGS IN ACCORDANCE WITH SMACNA. (WYES, RADIUSED

OR VANED TEES, ETC.) DUCTWORK SHALL BE GALVANIZED

SHEET METAL, MIN. 26 GA.

22. ALL DUCT DIMENSIONS SHOWN ARE INSIDE CLEAR DIMENSION.

INCREASE DUCT SIZE FOR LINING.

23. LINE 10'-0" OF SUPPLY DUCTWORK AFTER EACH VAV BOX.

24. ALL EXTERNALLY ISOLATED HVAC EQUIPMENT SHALL HAVE

FLEXIBLE DUCT CONNECTORS.

25. ALL CONDENSATE DRAIN PIPING SET @ MIN. 1% SLOPE.

26. ALL CONDENSATE DRAIN PIPING TO TERMINATE TO DRAIN VIA

AIR GAP.

27. IF THERE IS CONFLICTING INFORMATION IN THE PLANS OR

SPECIFICATIONS THE MORE STRINGENT AND GREATER COST

ITEM SHALL BE USED.

28. DRAWINGS INDICATE REQUIRED SIZES AND POINTS OF

TERMINATION OF PIPES AND DUCTS AND SUGGESTED ROUTES.

IT IS NOT INTENTION OF DRAWINGS TO INDICATE ALL

NECESSARY OFFSETS. INSTALL WORK IN MANNER TO

CONFORM TO STRUCTURE, AVOID OBSTRUCTIONS, PRESERVE

HEADROOM AND KEEP OPENINGS AND PASSAGEWAYS CLEAR.

DO NOT SCALE FROM DRAWINGS.
