GENERAL MECHANICAL NOTES

1. INSTALLATION OF HVAC WORK SHALL BE COORDINATED WITH OTHER TRADES BEFORE ANY INSTALLATION IS MADE. DUCTWORK SHOWN ON PLANS IS SCHEMATIC. DUCTWORK SHALL BE INSTALLED TIGHT TO STRUCTURE. ALL TRANSITIONS, ELBOWS, ETC.

REQUIRED TO AVOID CONFLICTS & MAXIMIZE CEILING HEIGHTS. EQUIPMENT, PIPING OR DUCTWORK INTERFERING WITH OTHER

TRADES SHALL BE RELOCATED AS REQUIRED AT NO ADDITIONAL COST TO THE OWNER.

2. COORDINATE MECHANICAL AND ELECTRICAL SUCH THAT MECHANICAL PIPING, DUCTWORK AND EQUIPMENT IS NOT LOCATED

OVER OR ABOVE ANY ELECTRICAL, COMMUNICATIONS, OR DATA EQUIPMENT.

3. WRITTEN DIMENSIONS ON DRAWINGS SHALL HAVE PRECEDENCE OVER SCALED DIMENSIONS.

4. EQUIPMENT SHALL BE INSTALLED IN ACCORDANCE WITH MANUFACTURER'S APPROVED CLEARANCE, UNIFIED FACILITIES

CRITERIA, AND INTERNATIONAL BUILDING CODE / INTERNATIONAL MECHANICAL CODE.

5. INSTALLATION OF EQUIPMENT SHALL PERMIT ACCESSIBILITY FOR SERVICE AND/OR REPLACEMENT WITHOUT NECESSITATING

REMOVAL OR MODIFICATION TO OTHER PIPING, WIRING, OR EQUIPMENT.

6. CEILING-MOUNTED EQUIPMENT SHALL BE INSTALLED IN SUCH A MANNER THAT LIGHTS, PIPING, DUCTWORK, ETC., DO NOT

BLOCK ACCESS TO EQUIPMENT AND RELATED ACCESSORIES.

7. COORDINATE WALL PENETRATIONS WITH THE GENERAL CONTRACTOR.

8. CAULK WITH SILICONE ALL GAPS BETWEEN WALL, CEILING AND FLOOR OPENINGS AND HVAC EQUIPMENT PENETRATIONS.

PATCH LARGE GAPS BEFORE CAULKING IS APPLIED.

9. DUCTWORK AIR DISTRIBUTION SYSTEMS SHALL BE INSTALLED IN ACCORDANCE WITH SMACNA STANDARDS AND THE PRESSURE

CLASSIFICATION OF EACH INDIVIDUAL DUCTWORK SYSTEM.

10. VOLUME DAMPERS SHALL BE PROVIDED AT EACH NEW MAIN BRANCH TAKE-OFF AND IN SUCH OTHER LOCATIONS WHERE

REQUIRED TO PROPERLY BALANCE THE SYSTEM.

11. INSTRUMENT TEST HOLES SHALL BE PROVIDED IN AIR DISTRIBUTION SYSTEMS WHEREVER VOLUME DAMPERS ARE INSTALLED.

12. SQUARE ELBOWS SHALL ONLY BE USED WHERE SPACE LIMITATIONS PREVENT USE OF 1.5 RADIUS ELBOW AND ONLY UPON APPROVAL OF CONTRACTING OFFICER. PROVIDE TURNING VANES IN ALL 45° AND 90° SQUARE ELBOWS. TURNING VANES SHALL BE SINGLE THICKNESS TYPE WITHOUT RAILING EDGE. TURNING VANES LONGER THAN 36 INCHES SHALL BE DOUBLE THICKNESS

TYPE.

13. DUCTWORK RUNOUTS TO AIR DISTRIBUTION DEVICES SHALL BE SAME DIAMETER AS AIR DISTRIBUTION DEVICE INLET

CONNECTION UNLESS OTHERWISE NOTED ON THE DRAWINGS.

14. FLEXIBLE DUCTWORK RUNOUTS FROM BRANCH DUCTS TO AIR DISTRIBUTION DEVICES SHALL NOT EXCEED 5 FEET IN LENGTH.

BENDS IN FLEXIBLE DUCTWORK SHALL NOT EXCEED A MAXIMUM OF 45 DEGREE CHANGE OF DIRECTION AND BE SUPPORTED SUCH THAT THE BEND RADIUS IS NOT RESTRICTIVE TO AIR FLOW THROUGH THE DUCT. FLEXIBLE DUCTWORK SHALL NOT BE

CRUSHED OR DISTORTED IN ITS FINAL CONFIGURATION.

15. ROUND DUCTWORK CONNECTIONS BETWEEN MAIN DUCT AND TERMINAL UNITS SHALL BE RIGID DUCT OF THE SAME DIAMETER

AS TERMINAL UNIT INLET CONNECTION UNLESS OTHERWISE NOTED ON THE DRAWINGS.

16. PROVIDE SHEET METAL TRANSITIONS AT AIR HANDLING UNITS, HEAT PUMP UNITS, FANS, AND OTHER SIMILAR HVAC EQUIPMENT.

TRANSITION TO FULL SIZE OF CONNECTION ON UNIT. FLEXIBLE DUCT CONNECTORS SHALL BE USED ON FINAL CONNECTION TO

AIR HANDLING EQUIPMENT.

17. DIMENSIONS SHOWN FOR DIFFUSERS AND GRILLES ARE NECK DIMENSIONS.

18. EXACT LOCATION OF CEILING DIFFUSERS, GRILLES AND REGISTERS SHALL BE DETERMINED BY ARCHITECTURAL REFLECTED

CEILING PLAN.

19. PROVIDE ACCESS PANELS TO ACCESS DAMPERS, EQUIPMENT, AND VALVES LOCATED ABOVE HARD CEILINGS OR IN WALLS.

ACTUAL LOCATIONS SHALL BE FIELD DETERMINED.

21. SUPPLY AND RETURN DUCTWORK SHALL BE INSULATED TO MEET OR EXCEED ASHRAE 90.1.

22. MANUFACTURER NAME AND MODEL NUMBERS ARE BASIS OF DESIGN AND ARE SHOWN FOR INFORMATION ONLY. REFER TO

SPECIFICATIONS FOR COMPLETE REQUIREMENTS.

23. SPECIFICATIONS TAKE PRECEDENCE OVER DRAWINGS. HOWEVER, ITEMS SHOWN ON DRAWINGS BUT NOT IN THE SPECIFICATIONS ARE REQUIRED WITHIN THE PROJECT SCOPE. IN ADDITION, SPECIFIC ITEMS SHOWN ON THE DRAWINGS TAKE

PRECEDENCE OVER SPECIFICATIONS IN CASES WHERE THE SPECIFICATION HAS OPTIONS.

24. ALL EQUIPMENT SHALL BE INSTALLED IN ACCORDANCE WITH MANUFACTURER'S APPROVED PUBLISHED LITERATURE.

25. DUCT SIZES SHOWN ARE INSIDE CLEAR DIMENSIONS.

26. NOT ALL MECHANICAL ABBREVIATIONS SHOWN WILL BE USED FOR THIS PROJECT.

SEQUENCE OF OPERATION:

1. VAV-1 SHALL MAINTAIN CONSTANT AIR FLOW AS SCHEDULED.

THE ROOM TEMPERATURE SENSOR SHALL MODULATE THE

REHEAT CONTROL VALVE AS NEEDED TO MAINTAIN ROOM

TEMPERATURE SETPOINT.

2. BCU-1 SHALL OPERATE DURING OCCUPIED HOURS AS

DETERMINED BY THE EXISTING BUILDING MANAGEMENT SYSTEM.

A SUPPLY DUCT TEMPERATURE SENSOR SHALL MODULATE THE

CHILLED WATER CONTROL VALVE AS NEEDED TO MAINTAIN 55

DEG. F (ADJ) DISCHARGE AIR TEMPERATURE. A ROOM

TEMPERATURE SENSOR SHALL CONTROL THE FAN VFD AND

ADJUST AIR FLOW AS NEEDED TO MAINTAIN ROOM TEMPERATURE

SETPOINT. UPON FAN REACHING MINIMUM AIR FLOW THE

DISCHARGE AIR TEMPERATURE SHALL RISE 1 DEG. F AT A TIME TO

A MAXIMUM OF 60 DEG. F (ADJ) TO ACHIEVE ROOM TEMPERATURE

SETPOINT. A FLOAT SWITCH IN THE AUX DRAIN SHALL STOP THE

FAN AND ALARM THROUGH THE BUILDING MANAGEMENT SYSTEM

UPON ACTIVATION.
