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, FLOOR AND ROOF 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. 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.

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

CONNECTION UNLESS OTHERWISE NOTED ON THE DRAWINGS.

12. 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.

13. 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.

14. 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.

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

CEILING PLAN.

16. BLANK OFF AND INSULATE INACTIVE PORTIONS OF LOUVERS. ENTIRE LOUVERS NOT UTILIZED SHALL BE BLANKED OFF AND INSULATED BY THE LOUVER MANUFACTURER. REFER TO ARCHITECTURAL DRAWINGS FOR LOUVER LOCATIONS AND HVAC

DRAWINGS FOR HVAC EQUIPMENT CONNECTIONS.

17. LOUVER PLENUMS SHALL BE PITCHED DOWN TOWARD THE BOTTOM OF THE LOUVER. WHERE THIS IS NOT POSSIBLE, PROVIDE 3/4" DRAIN PIPING WITH P-TRAP FROM BOTTOM OF LOUVER TO NO MORE THAN 6" ABOVE NEAREST SANITARY DRAIN. DRAIN LINE SHALL SLOPE DOWN TOWARDS DISCHARGE LOCATION AT A MINIMUM OF 1/8" PER LINEAR FOOT.

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

ACTUAL LOCATIONS SHALL BE FIELD DETERMINED.

19. EXACT LOCATIONS OF THERMOSTATS, CO2 SENSORS, AND EMCS SENSORS SHALL BE COORDINATED WITH FINAL LOCATIONS OF WALL-MOUNTED ARCHITECTURAL AND ELECTRICAL EQUIPMENT. MOUNT THERMOSTATS AND CO2 SENSORS MINIMUM 48" AFF.

20. AIR HANDLING UNITS SERVING OCCUPIED AREAS SHALL HAVE MINIMUM MERV 13 FILTERS. UNITS NOT SERVING OCCUPIED ZONES SHALL HAVE MINIMUM MERV 8 FILTER. FILTERS SHALL BE INDUSTRY STANDARD SIZE.

AIR HANDLERS AHU/CU-1 & AHU/CU-2

1. THE UNITS SHALL OPERATE AS SCHEDULED BY THE BUILDING MANAGEMENT SYSTEM (BMS)

a. DURING OCCUPIED THE SYSTEMS SHALL OPERATE WITH LOCAL CONTROLS AS NOTED HERE IN AFTER.

b. DURING UNOCCUPIED HOURS, A SPACE TEMPERATURE SENSOR SHALL SIGNAL TO THE BMS TO OPERATE THE SYSTEMS AS NEEDED TO

MAINTAIN 60 DEGREES F (ADJ.) IN THE WINTER AND 80 DEGREES F (ADJ.) IN THE SUMMER.

2. A SPACE THERMOSTAT SHALL CYCLE THE UNIT IN HEATING OR COOLING AS NEEDED TO MAINTAIN SET POINT TEMPERATURE. THE SENSOR

FOR THE THERMOSTAT SHALL BE IN THE ASSOCIATED AIR HANDLER RETURN DUCTWORK AS NOTED ON THE DRAWINGS.

a. THE THERMOSTAT SHALL OPERATE THE EMERGENCY STRIP HEAT AS NEEDED TO MAINTAIN SPACE SET POINT TEMPERATURE UPON

FAILURE OF THE COMPRESSOR TO MAINTAIN SET POINT TEMPERATURE OR DEHUMIDIFICATION OPERATION.

3. MOTORIZED DAMPERS IN THE OUTSIDE AIR DUCTWORK SHALL OPEN DURING OCCUPIED HOURS AND REMAIN CLOSED DURING SET UP OR SET

BACK TEMPERATURE OPERATION AND UNOCCUPIED CONDITIONS.

4. A SMOKE DETECTOR IN THE RETURN AIR DUCTWORK SHALL STOP THE UNIT, CLOSE THE OUTSIDE AIR DAMPER, AND ALARM THE BUILDING

FIRE ALARM AND BMS SYSTEMS UPON ACTIVATION.

5. A SPACE HUMIDISTAT SHALL ENERGIZE THE COOLING FUNCTION FOR UNITS AS NEEDED TO MAINTAIN SPACE HUMIDITY LEVELS AT 60% RH

(ADJ.). THE EMERGENCY STRIP HEAT SHALL CYCLE BY THE ROOM THERMOSTAT AS NEEDED TO MAINTAIN SPACE TEMPERATURE.

6. AHU-2 WILL BE INSTALLED IN AN AUXILIARY DRAIN PAN WITH A FLOAT SWITCH TO DEENERGIZE THE UNIT UPON ACTIVATION.

EXHAUST FANS EF-1 & EF-2

1. THE EXHAUST FAN EF-1 SHALL OPERATE WHEN AHU-1 &/OR AHU-2 ARE OPERATING AND THE AHU’S OUTSIDE AIR DAMPERS ARE OPEN. THE

FAN SHALL BE DEENERGIZED DURING UNOCCUPIED CONDITIONS.

2. THE EXHAUST FAN EF-2 SHALL OPERATE WHEN AHU-1 IS OPERATING, AND THE OUTSIDE AIR DAMPER IS OPEN. THE FAN SHALL BE

DEENERGIZED DURING UNOCCUPIED CONDITIONS.

UNIT HEATERS EUH-1 & EUH-2

1. THE UNITS SHALL CYCLE AS NEEDED, BY A SPACE THERMOSTAT, TO MAINTAIN SET POINT OF 45 DEGREES F (ADJ.) IN THE ATTIC.

DUCTLESS SPLIT SYSTEM AC-1

1. THE UNIT SHALL CYCLE AS NEEDED TO MAINTAIN ROOM THERMOSTAT SET POINT OF 72 DEGREES F (ADJ.). THE UNIT SHALL OPERATE

CONTINUOUSLY. A SPACE TEMPERATURE SENSOR IN THE ROOM SHALL ALARM THE BMS UPON SPACE TEMPERATURES ABOVE 75 DEGREES F

(ADJ.).

DEHUMIDIFER DH-1

1. THE UNIT SHALL OPERATE AS NEEDED WITH UNIT CONTROLS TO MAINTAIN ROOM AT 50% RH (ADJ.). A HUMIDITY SENSOR SHALL ALARM THE

BMS UPON SPACE HUMIDITY ABOVE 65% RH (ADJ.).
