6. COORDINATE WORK WITH THE OTHER TRADES IN ORDER TO RESOLVE ANY CONFLICT THAT MIGHT ARISE DUE TO THE LOCATION OF EQUIPMENT OR THE

USE OF SPACE.

7. EQUIPMENT OF HIGHER ELECTRICAL CHARACTERISTICS MAY BE SUBSTITUTED PROVIDED SUCH PROPOSED EQUIPMENT IS APPROVED IN WRITING AND CONNECTING ELECTRICAL SERVICE, CIRCUIT BREAKERS AND CONDUIT SIZES ARE APPROPRIATELY MODIFIED AT NO COST TO THE OWNER.

8. RUN ALL HORIZONTAL PIPING AND DUCTWORK ABOVE CEILING UNLESS OTHERWISE NOTED.

9. MAKE DUCT PENETRATIONS OF ALL WALLS WITH SHEET METAL DUCTS. FLEXIBLE DUCT PENETRATIONS OF WALLS ARE NOT ACCEPTABLE.

10. REFER TO ARCHITECTURAL REFLECTED CEILING PLANS FOR EXACT LOCATION OF DIFFUSERS, REGISTERS, AND GRILLES. FINISH AND COLOR TO BE

SELECTED BY CONTRACTING OFFICER FROM MANUFACTURER'S STANDARD PALETTE.

11. DUCTWORK SIZES ARE INSIDE CLEAR DIMENSIONS.

12. ALL ELBOWS IN DUCTWORK SHALL BE RADIUS ELBOWS UNLESS OTHERWISE NOTED. WHERE SQUARE ELBOWS ARE SHOWN, INSTALL DOUBLE WALL TURNING VANES. RADIUS ELBOWS SHALL HAVE A MINIMUM CENTERLINE RADIUS OF CURVATURE OF 1.5 TIMES DUCT WIDTH OR DIAMETER

13. PROVIDE DYNAMIC FIRE DAMPER IN ACCORDANCE WITH THEIR UL LISTING AND THE REQUIREMENTS OF NFPA 90A.

14. DO NOT INSTALL EQUIPMENT, PIPING OR DUCTWORK OVER ANY ELECTRICAL EQUIPMENT OR ELECTRICAL SERVICE SPACE.

15. LAYOUT OF PIPING AND DUCTWORK IS DIAGRAMMATIC. RUN ALL EXPOSED PIPING AND DUCTWORK AS HIGH AS POSSIBLE UNLESS OTHERWISE NOTED.

ALLOW FOR RISES, DROPS AND OFFSETS AS REQUIRED.

16. EXTEND DRAIN LINES TO NEAREST DRAIN OR AS INDICATED. ALL CONDENSATE DRAIN PIPING MUST BE TRAPPED AND PITCHED DOWN IN DIRECTION OF

FLOW A MINIMUM OF 12.5%.

17. INSTALL MECHANICAL EQUIPMENT TO FACILITATE SERVICING, MAINTENANCE, AND REPAIR OR REPLACEMENT OF EQUIPMENT COMPONENTS. CONNECT EQUIPMENT FOR EASE OF DISCONNECTING, WITH A MINIMUM OF INTERFERENCE WITH OTHER INSTALLATIONS. PIPING MUST NOT INTERFERE WITH FILTER PULL. MAINTAIN EQUIPMENT MANUFACTURER'S RECOMMENDED MINIMUM SERVICE CLEARANCE.

18. MECHANICAL CONTRACTOR MUST PROVIDE AUTOMATIC CONTROL DEVICES, SUCH AS TEMPERATURE SENSORS, RELAYS, PRESSURE SWITCHES WHICH ARE ASSOCIATED WITH MECHANICAL EQUIPMENT AND ASSOCIATED CONTROL WIRING FROM STARTER TO THE CONTROL DEVICE. ELECTRICAL CONTRACTOR SHALL PROVIDE CONDUIT AND WIRING FROM POWER SOURCE TO DISCONNECT SWITCH, FROM DISCONNECT SWITCH TO STARTER, AND

FROM STARTER TO THE EQUIPMENT.

19. ALL CONTROL WIRING EXCEPT IN EQUIPMENT ROOMS MUST BE RUN CONCEALED. WIRING IN WALLS MUST BE IN CONDUIT. ALL WIRING MUST BE PLENUM RATED. CONTROL WIRING IN EXPOSED AREAS SHALL BE BUNDLED AND SECURED OR RUN IN CONDUIT. NO WIRING SHALL BE SURFACE MOUNTED IN FINISHED SPACES. ALL ELECTRICAL WORK MUST BE IN ACCORDANCE WITH NATIONAL ELECTRICAL CODE.

20. LOCATE THERMOSTATS 1220mm ABOVE FINISHED FLOOR OR AS NOTED ON THE PLANS.

21. ALL VALVES ARE FULL LINE SIZE EXCEPT CONTROL AND BALANCING VALVES. SIZE CONTROL VALVES TO OPERATE ACROSS THE FULL RANGE OF FLOW

AT THE COIL SERVED.

22. PROVIDE PRESSURE/TEMPERATURE (P/T) PLUGS, WITH CAPS UP AND DOWNSTREAM OF ALL EQUIPMENT, AT THE SUPPLY AND RETURN TAPS OF ALL PIPING BRANCHES AND WHERE INDICATED. PROVIDE EXTENDED PLUGS AND LABELS WHERE PIPING IS INSULATED. PROVIDE REMOVABLE INSULATION

PLUG.

VAV AIR-HANDLING UNIT (AHU-1H) WITH SPLIT

DEHUMIDIFICATION UNIT (SDU) SEQUENCE OF OPERATION

NO

THE AIR-HANDLING UNIT AND COORDINATED CONTROLS OPERATE CONTINUOUSLY. THE OUTSIDE AND RETURN AIR DAMPERS OPEN AND PROVEN, AND THE EXHAUST AIR DAMPER OPEN AND PROVEN BEFORE THE AHU AND INTERLOCKED EXHAUST FAN ARE ENABLED. THE VARIABLE SPEED DRIVE MUST MODULATE THE SUPPLY FAN SPEED TO MAINTAIN DUCT STATIC PRESSURE IN THE DUCT AT A POINT 2/3 FROM FAN OUTLET TO END OF THE DUCT. DUCT STATIC PRESSURE MUST BE RESET BASED ON THE ZONE REQUIRING THE MOST PRESSURE (I.E., THE SET POINT IS RESET TO A LOWER VALUE UNTIL ONE ZONE DAMPER IS AT 90% OPEN. UPON ANY ZONE DAMPER MOVING TO 100% OPEN, STATIC PRESSURE MUST BE RESET TO A HIGHER VALUE). UPON FAILURE OF ZONE TERMINAL CONTROL LOOP, FAN SPEED MUST BE MODULATED BASED UPON THE DUCT STATIC PRESSURE. OUTSIDE AIRFLOW WILL BE MONITORED BY AN AIRFLOW MEASURING STATION: OUTSIDE AIR DAMPER WILL MODULATE TO MAINTAIN THE SCHEDULED VENTILATION AIRFLOW WHILE THE UNIT SUPPLY AIRFLOW IS VARIABLE.

COOLING (RETURN AIR):

WITH THE RETURN AIR DAMPER OPEN, THE UNIT CHILLED WATER CONTROL VALVE MUST BE MODULATED TO MAINTAIN UNIT DISCHARGE AIR TEMPERATURE SET POINT (12.8°C). ON A RISE IN UNIT DISCHARGE AIR TEMPERATURE THE VALVE MUST MODULATE OPEN: ON A FALL IN TEMPERATURE THE REVERSE MUST OCCUR.

COOLING (OUTSIDE AIR):

WITH THE OUTSIDE AIR DAMPER OPEN, THE SPLIT DEHUMIDIFICATION CHILLED WATER CONTROL VALVE MUST BE MODULATED TO MAINTAIN COOLING COIL DISCHARGE AIR TEMPERATURE SET POINT (11.1°C) FOR DEHUMIDIFICATION. ON A RISE IN COIL DISCHARGE AIR TEMPERATURE THE VALVE MUST MODULATE OPEN:

ON A FALL IN TEMPERATURE THE REVERSE MUST OCCUR.

SAFETIES AND ALARMS:

UPON SENSING PRESSURE ABOVE ITS SET POINT (ADJUSTABLE), THE HIGH LIMIT PRESSURE SENSOR MUST SHUT DOWN THE SYSTEM AND INITIATE AN ALARM ON THE DDC SYSTEM: THE ALARM MUST REQUIRE MANUAL RESET EITHER AT THE UNIT OR THE CENTRAL BUILDING CONTROLS. ONCE CLEARED THE STATIC PRESSURE MUST RETURN TO NORMAL CONTROL. UPON SENSING PRODUCTS OF COMBUSTION BY THE SUPPLY AIR DUCT SMOKE DETECTOR, THE ASSOCIATED SUPPLY FAN AND EXHAUST FAN EF-1 MUST BE DE-ENERGIZED, ALL DAMPERS MUST BE PLACED IN THEIR CLOSED POSITIONS, AND A SIGNAL MUST BE SENT TO THE FIRE ALARM PANEL. DIFFERENTIAL PRESSURE SENSORS (ADJUSTABLE) MUST MONITOR THE PRESSURE ACROSS THE UNIT FILTERS (BOTH RETURN AND OUTSIDE AIR). UPON SENSING PRESSURE AT ITS “DIRTY” SET POINT (62 Pa) A TROUBLE SIGNAL MUST BE INITIATED FOR DIRTY FILTER STATUS. THE SYSTEM MUST MONITOR ALL VFD SAFETIES. THE SYSTEM MUST MONITOR RETURN AIR, SUPPLY AIR, AND OUTSIDE AIR TEMPERATURES. THE SYSTEM MUST MONITOR THE RETURN AIR AND OUTSIDE AIR RELATIVE HUMIDITY. THE SYSTEM MUST MONITOR THE OUTDOOR AIR AND EXHAUST FANS MOTOR STATUS.
