GENERAL ITEMS

GENERAL NOTES ON THIS DRAWING ARE APPLICABLE TO EACH HVAC DRAWING OF

THIS SET. SEE EACH DRAWING FOR SPECIFIC NOTES APPLICABLE TO THAT DRAWING.

COORDINATE LOCATION AND INSTALLATION OF EQUIPMENT WITH OTHER TRADES.

DO NOT SCALE DRAWINGS. SEE ARCHITECTURAL DRAWINGS FOR EXACT LOCATIONS

OF DOORS, WINDOWS, ETC.

THERMOSTATS AND/OR TEMPERATURE SENSORS SHALL BE LOCATED IN THE ROOMS

INDICATED. INSTALL AT APPROX. 46" ABOVE FINISH FLOOR TO MATCH THE HEIGHT OF

WALL SWITCHES OR OTHER WALL MOUNTED DEVICES.

DUCTWORK, VENTS, ETC., EXTENDING THROUGH EXTERIOR WALLS AND ROOF SHALL

BE FLASHED AND COUNTER FLASHED IN A WEATHERPROOF MANNER.

FOR LOCATION OF MOTOR STARTERS, SEE ELECTRICAL DRAWINGS.

SHEET METAL

DUCTWORK SHALL BE CONSTRUCTED TO THE SMACNA STATIC PRESSURE

CLASSIFICATION OF 2 IN. WG AND SEAL CLASS "A".

MAINTENANCE

PROVIDE ACCESS TO ANY INSPECTION OR MAINTAINABLE DEVICE, EQUIPMENT, ETC. -

ACCESS OR ACCESS DOOR SHALL BE OF ADEQUATE SIZE TO WORK ON DEVICE.

EXAMINE MANUFACTURER'S LITERATURE TO DETERMINE RECOMMENDED

CLEARANCES. THESE CLEARANCES, IN ADDITION TO MINIMUM CLEARANCES

REQUIRED BY THE NATIONAL ELECTRICAL CODE, SHALL BE ESTABLISHED AND

MAINTAINED. THIS APPLIES TO NEW AND EXISTING EQUIPMENT IMPACTED BY THIS

PROJECT AS WELL. THE CONTRACTOR SHALL BE RESPONSIBLE FOR COORDINATING

THESE REQUIREMENTS WITH ALL OTHER TRADES.

INTERDISCIPLINARY COORDINATION

IF THIS CONTRACTOR SHOULD ELECT TO PROPOSE ANY EQUIPMENT THAT HAS

DIFFERENT PHYSICAL OR ELECTRICAL CHARACTERISTICS, ETC. WHEN COMPARED TO

THE BASIS OF DESIGN EQUIPMENT, THIS CONTRACTOR IS RESPONSIBLE FOR

COORDINATING THESE CHANGES WITH THE OTHER TRADES PRIOR TO ORDERING OF

EQUIPMENT. IF THERE SHOULD BE ANY ADDITIONAL WORK INCURRED BY THE OTHER

TRADES AS A RESULT OF THIS CONTRACTOR'S EQUIPMENT SELECTION, ALL COSTS

ASSOCIATED WITH THE ADDITIONAL WORK SHALL BE BORNE BY THIS CONTRACTOR.

PUSHBUTTON WITH PLASTIC LIFT COVER APPROXIMATELY 48” AFF. PROVIDE SIGNAGE INDICATING “EMERGENCY HVAC SYSTEM/VENTILATION SHUTDOWN”. PER THE REQUIREMENTS OF UFC 4-010-01, SECTION B-4.3, EACH FACILITY SHALL BE OUTFITTED WITH AN EMERGENCY AIR DISTRIBUTION SYSTEM

SHUTOFF SWITCH WHICH SHALL IMMEDIATELY SHUTDOWN ALL AIR DISTRIBUTION SYSTEM

COMPONENTS (I.E. EXHAUST FANS) INCLUDING CLOSING OF ALL ISOLATION DAMPERS. THE SWITCH SHALL BE ACTIVATED IF BUILDING OCCUPANTS SUSPECT AIRBORNE CONTAMINANTS MAY BE PRESENT IN THE VICINITY OF THE FACILITY. LOCATE THE SHUTOFF SWITCH SUCH THAT IT IS EASILY ACCESSIBLE BY BUILDING OCCUPANTS BY LOCATING IT NEXT TO THE MANUAL FIRE ALARM PULL STATION. THE MOTORIZED DAMPERS ON THE EXHAUST FANS AND INTAKE LOUVERS SHALL BE LOW LEAKAGE TYPE.

PROVIDE FIRE ALARM ADDRESSABLE RELAYS AT THE STARTER CIRCUIT FOR EACH MOTOR POWERED

COMPONENT OF THE HVAC SYSTEM (EXHAUST FANS AND MOTORIZED DAMPERS) AND CONNECT TO

STARTER (SHUTDOWN) CIRCUITS, TAKING CARE NOT TO EXCEED RELAY RATINGS. PROVIDE MONITOR

MODULES AT EACH MOMENTARY CONTACT PUSHBUTTON STATION TO MONITOR THE STATE OF THE

CONTACTS. PROGRAM THE FIRE ALARM SYSTEM, UPON A CHANGE OF STATE OF THE PUSHBUTTON, TO INSTANTLY DEACTIVATE AND SHUTDOWN ALL OF THE MOTOR OPERATED FUNCTIONS OF THE HVAC

SYSTEM. SHUTDOWN OF THE UNITS SHALL REMAIN UNTIL THE FIRE ALARM SYSTEM IS RESET.
