1. THIS PROJECT IS A RENOVATION OF AN EXISTING FACILITY. IT IS THE CONTRACTOR'S RESPONSIBILITY TO FIELD VERIFY ALL DIMENSIONS PRIOR TO FABRICATION OR PURCHASE OF EQUIPMENT, MATERIALS, AND ASSEMBLIES. ANY DEVIATIONS MUST BE BROUGHT TO THE CONTRACTING OFFICER'S ATTENTION FOR RESOLUTION BEFORE PROCEEDING WITH ANY

CONSTRUCTION, FABRICATION, OR EQUIPMENT PURCHASE.

2. INSTALLATION OF HVAC WORK MUST BE COORDINATED WITH OTHER TRADES BEFORE ANY INSTALLATION IS DONE. PIPING SHOWN ON PLANS IS SCHEMATIC. PROVIDE ALL TRANSITIONS, ELBOWS, REDUCERS, ETC. REQUIRED TO AVOID

CONFLICTS.

3. WRITTEN DIMENSIONS ON DRAWINGS MUST HAVE PRECEDENCE OVER SCALED DIMENSIONS. VERIFY DIMENSIONS ON SITE.

4. EQUIPMENT MUST BE INSTALLED IN ACCORDANCE WITH MANUFACTURER'S APPROVED CLEARANCE, USDA ARS 242.1, AND

INTERNATIONAL BUILDING CODE / INTERNATIONAL MECHANICAL CODE.

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

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

6. CONTRACTOR MUST COORDINATE WALL, FLOOR, AND ROOF PENETRATIONS.

7. CAULK WITH SILICONE ALL GAPS BETWEEN WALL, CEILING, AND FLOOR OPENINGS AND PIPING PENETRATIONS. PATCH LARGE GAPS BEFORE CAULKING IS APPLIED. PROVIDE FIRESTOPPING FOR ALL FIRE/SMOKE RATED WALLS, FLOORS, AND

CEILINGS.

8. EXACT LOCATIONS OF CONTROL DEVICES MUST BE COORDINATED WITH THE CONTROLS CONTRACTOR.

9. SPECIFICATIONS TAKE PRECEDENCE OVER DRAWINGS. HOWEVER, ITEMS SHOWN ON DRAWING 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.

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

11. ALL EQUIPMENT INSTALLED IN THIS PROJECT MUST COMPLY WITH THE "BUY AMERICAN ACT". BASIS OF DESIGN

SHOWN ON SCHEDULES IS TO ESTABLISH A STANDARD OF QUALITY, NOT TO LIMIT COMPETITION. EQUIVALENT EQUIPMENT FROM ANOTHER MANUFACTURER IS ACCEPTABLE. MANUFACTURER NAME AND MODEL NUMBERS ARE BASIS OF DESIGN AND ARE SHOWN FOR INFORMATION ONLY. REFER TO SPECIFICATIONS FOR COMPLETE

REQUIREMENTS.

12. CONTROLS CONTRACTOR MUST PROVIDE ALL LOW VOLTAGE DEVICES, CONDUCTORS, AND PATHWAYS IN ACCORDANCE WITH THE REQUIREMENTS OF 26 20 00. INSTALL CONTROL WIRING IN CONDUIT. SEE DIVISION 26 SPECIFICATIONS FOR

REQUIREMENTS.

HVAC GENERAL NOTES:

1. THE DEMOLITION PLANS AND EXISTING CONDITIONS SHOWN ARE APPROXIMATE AND ARE TO BE FIELD VERIFIED. ITEMS TO

BE REMOVED ARE DENOTED BY HATCHING.

2. DEMOLITION MUST INCLUDE, BUT IS NOT LIMITED TO, THE ITEMS IDENTIFIED. THE CONTRACTOR MUST COORDINATE ALL REQUIRED RENOVATION AND NEW CONSTRUCTION WITH THE EXISTING BUILDING TO IDENTIFY THE TOTAL EXTENT OF THE

DEMOLITION WORK REQUIRED.

3. THE CONTRACTOR IS RESPONSIBLE FOR THE DEMOLITION AND REMOVAL OF ALL EXISTING BUILDING COMPONENTS, MATERIALS, EQUIPMENT, AND APPURTENANCES AS REQUIRED TO BUILD, ERECT, INSTALL, OR ACCOMMODATE ALL NEW

CONSTRUCTION.

4. IN THE EVENT THE CONTRACTOR ENCOUNTERS MATERIAL REASONABLY BELIEVED TO BE ASBESTOS, LEAD-BASED PAINT, OR ANY OTHER HAZARDOUS MATERIAL WHICH HAS NOT BEEN RENDERED HARMLESS, THE CONTRACTOR MUST

IMMEDIATELY REPORT THE CONDITION TO THE CONTRACTING OFFICER IN WRITING.

5. THE CONTRACTOR IS RESPONSIBLE FOR THE ERECTION, MAINTENANCE, AND REMOVAL OF ALL CONSTRUCTION

ASSISTANCE DEVICES SUCH AS SCAFFOLDING AND BARRIERS.

6. THE BUILDING ENVELOPE MUST REMAIN WATERTIGHT THROUGHOUT THE CONSTRUCTION PROCESS.

7. IF IT BECOMES NECESSARY DURING DEMOLITION TO TEMPORARILY REMOVE ANY EXISTING WORK NOT SPECIFICALLY NOTED TO BE REMOVED OR RELOCATED (THEREBY IMPLYING THAT THEY ARE TO BE LEFT FOR FUTURE USE), THE CONTRACTOR MUST REINSTALL SAID WORK TO FULLY OPERABLE CONDITION IN THEIR ORIGINAL LOCATIONS

8. CONTRACTOR MUST DEMOLISH ALL EQUIPMENT, PIPING, INSULATION, SUPPORTS, CONTROLS THERMOSTATS, WIRING

AND ALL APPURTENANCES WITH THE HVAC SYSTEM TO BE DEMOLISHED.

CHILLER PLANT CONTROLS - SCHEMATIC1

SCALE: NONEM-701

CHILLER STOP CYCLE:

WHEN THE DDC SYSTEM INDEXES THE CHILLER TO STOP THE FOLLOWING SHALL OCCUR:

A. THE CHILLER CONTROL PANEL SHALL INDEX CHILLER TO STOP.

B. THE CHILLER CONTROL PANEL SHALL DISABLE THE CONDENSER WATER PUMP AFTER A TIME DELAY AND

SEND A SIGNAL TO THE DDC SYSTEM TO DISABLE THE CHILLED WATER PUMP.

C. THE DDC SYSTEM SHALL CLOSE THE CHILLER ISOLATION VALVE ON THE CONDENSER WATER SUPPLY

AND ON THE CHILLED WATER RETURN ASSOCIATED WITH THE CHILLER.

CHILLER STAGING:

THE SYSTEM IS VARIABLE PRIMARY: THE CHILLERS CONTROL IS PRIMARY/STANDBY WHERE EACH CHILLER IS SIZED AT 100% OF THE REQUIRED LOAD. SOFTWARE PRIMARY/STANDBY FUNCTION SHALL ALLOW EITHER OF THE CHILLERS TO ACT AS THE PRIMARY CHILLER BY OPENING/CLOSING THE ASSOCIATED ISOLATION VALVES FOR EACH CHILLER. THE STANDBY CHILLER SHALL REMAIN OFF UNTIL RECEIVING A COMMAND TO TO ACTIVATE FROM THE DDC. THE CHILLED WATER PUMP SHALL ADJUST TO MAINTAIN THE CHILLED WATER DIFFERENTIAL PRESSURE

(FLOW RATE, AS RECOMMENDED BY THE MANUFACTURER) FOR THE CHILLERS.

DESIGNATING PRIMARY, STANDBY AND 'OUT OF SERVICE' CHILLERS:

THE CHILLER PLANT GRAPHICAL SCREEN SHALL ALLOW THE OPERATOR TO DESIGNATE WHICH CHILLER IS PRIMARY, STANDBY, AND 'OUT OF SERVICE'. THE DDC SYSTEM SHALL CHANGE THE PRIMARY/ STANDBY STATUS OF THE CHILLERS ON A WEEKLY BASIS. THE DDC SYSTEM SHALL THEN AUTOMATICALLY START/STOP CHILLERS AS

REQUIRED TO MAINTAIN EQUAL CHILLER RUN TIME.

CHILLED WATER PUMP CONTROL:

ALL CHILLED WATER PUMPS ARE SIZED FOR 100% SYSTEM CAPACITY AS VARIABLE SPEED PRIMARY CONFIGURATION. THE DDC SYSTEM SHALL START THE CHILLED WATER PUMP ASSOCIATED WITH THE ACTUVE CHILLER VIA THE VFD WHENEVER THE CHILLER CONTROL PANEL IS ENABLED AND CHILLER CONTROL PANEL IS

CALLING FOR COOLING. THE STANDBY PUMP SHALL REMAIN OFF.

THE DDC SYSTEM SHALL MODULATE OUTPUT TO THE PUMP VFD AS REQUIRED TO MAINTAIN DIFFERENTIAL

PRESSURE (DP) SETPOINT AT THE LOCATION OF THE DP TRANSMITTER.

THE DDC SYSTEM SHALL ALTERNATE THE PRIMARY/STANDBY PUMPS ON A WEEKLY BASIS WITH THEIR

ASSOCIATED CHILLER.

MINIMUM CHILLED WATER FLOW CONTROL:

DDC SYSTEM SHALL MODULATE THE CHILLED WATER PUMP SPEED CONTROL AS REQUIRED TO MAINTAIN MINIMUM FLOW THROUGH CHILLER. THE MINIMUM FLOW SHALL VERIFIED WITH THE EQUIPMENT MANUFACTURER.

ADEQUATE FLOW THROUGH EACH CHILLER SHALL BE DETERMINED BY THE CHILLER FLOW SENSOR.

CHILLER SAFETIES:

CONTRACTOR SHALL COORDINATE ALL SAFETY AND INTERLOCK REQUIREMENTS WITH CHILLER MANUFACTURER.

THE CONTROLS CONTRACTOR SHALL PROVIDE THE INSTALLATION AND WIRING OF CHILLED WATER FLOW SWITCHES AND OTHER COMPONENTS PROVIDED WITH CHILLER AS REQUIRED FOR PROPER OPERATION.

COOLING TOWER CONTROL:

WHEN THE WATER LEVEL IS AT THE “OPERATING LEVEL”, THE MAKE-UP WATER CONTROL VALVE SHALL BE CLOSED. AS THE WATER LEVEL DROPS TO “LOW LEVEL”, THE LEVEL SENSOR SHALL SEND A SIGNAL TO THE DDC

SYSTEM TO OPEN THE MAKE-UP WATER CONTROL VALVE.

TOWER START-UP:

UPON INITIAL SYSTEM START-UP THE TOWER BY-PASS VALVE AND INDIVIDUAL TOWER ISOLATION VALVES SHALL BE UTILIZED AND SEQUENCED TO WARM UP CONDENSER WATER SYSTEM FOR PROPER CHILLER OPERATION.

WHEN THE CONDENSER WATER SUPPLY TEMPERATURE IS ABOVE 55°F (ADJ.) (REFER TO CONDENSER WATER

TEMPERATURE RESET) THE DDC SYSTEM SHALL CALL FOR COOLING TOWER OPERATION.

COOLING TOWER FAN OPERATION:

ONCE CONDENSER WATER FLOW IS PROVEN, THE DDC SYSTEM SHALL START THE COOLING TOWER FAN VIA THE VFD. THE DDC SYSTEM SHALL STOP THE COOLING TOWER FAN WHEN THE VFD IS OPERATING AT MINIMUM SPEED AND CONDENSER WATER SUPPLY TEMPERATURE IS 5°F BELOW SETPOINT FOR 10 MINUTES (ADJ) OR IF

CONDENSER WATER FLOW IS NOT PROVEN.

THE PURPOSE OF THE COOLING TOWER FAN SPEED CONTROL IS TO MAINTAIN THE OPTIMAL CONDENSER WATER SUPPLY TEMPERATURE SETPOINT. THE DDC SYSTEM SHALL CONTROL THE COOLING TOWER FAN VFD USING A

4-20MA OUTPUT.

CONDENSER WATER PUMP:

THE CONDENSER WATER PUMP SHALL RUN ANYTIME THE COOLING TOWER IS CALLED TO RUN AND SHALL HAVE A USER DEFINABLE DELAY (ADJ.) ON STOP. THE CONDENSER WATER PUMP SHALL BE VARIABLE AND VARY FLOW AS

DEMAND CHANGES.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

A. CONDENSER WATER PUMP FAILURE: COMMANDED ON, BUT THE STATUS IS OFF.

B. CONDENSER WATER PUMP RUNNING IN HAND: COMMANDED OFF, BUT THE STATUS IS ON.

C. CONDENSER WATER PUMP RUNTIME EXCEEDED: STATUS RUNTIME EXCEEDS A USER DEFINABLE LIMIT
