GENERAL MECHANICAL NOTES

(APPLICABLE TO ALL MECHANICAL DRAWINGS)

1. ALL PIPING, DUCTWORK, EQUIPMENT, AND MATERIALS SHOWN "LIGHT" ( ) ARE EXISTING TO

REMAIN. DEMOLISH ALL PIPING, DUCTWORK, EQUIPMENT, AND MATERIALS SHOWN "HEAVY AND

DASHED" ( ) ON DEMOLITION DRAWINGS. PROVIDE ALL PIPING, DUCTWORK, EQUIPMENT,

AND MATERIALS SHOWN "HEAVY AND SOLID" ( ) ON NEW WORK DRAWINGS.

2. COORDINATE ALL MECHANICAL WORK WITH PLUMBING WORK, ELECTRICAL WORK, AND WORK OF

OTHER TRADES SHOWN ON OTHER DRAWINGS.

3. THE LOCATION OF EXISTING UTILITIES IS SHOWN IN AN APPROXIMATE WAY ONLY. DETERMINE THE EXACT LOCATION OF ALL EXISTING UTILITIES BEFORE COMMENCING WORK. REPAIR ALL DAMAGES

OCCASIONED BY FAILURE TO EXACTLY LOCATE AND PRESERVE ANY AND ALL UTILITIES.

4. RUN ALL DRAIN PIPING WITH 2 PERCENT MINIMUM GRADE UNLESS OTHERWISE NOTED.

5. INSTALL PIPING AND DUCTWORK SO THAT ALL VALVES AND DAMPERS ARE ACCESSIBLE.

6. UNLESS OTHERWISE NOTED, ROUTE ALL PIPING AND DUCTWORK OVERHEAD, TIGHT TO UNDERSIDE

OF LEVEL ABOVE, WITH SPACE FOR INSULATION IF REQUIRED.

7. CERTAIN ITEMS SUCH AS ACCESS DOORS, CLEANOUTS, RISE AND DROPS IN DUCTWORK AND

PIPING, ETC., ARE INDICATED ON THE DRAWINGS FOR CLARITY OR A SPECIFIC LOCATION

REQUIREMENT AND SHALL NOT BE INTERPRETED AS THE EXTENT OF THE REQUIREMENTS FOR

THESE ITEMS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR THESE ITEMS AS REQUIRED

ELSEWHERE IN THE CONTRACT DOCUMENTS.

8. WHERE THE INSTALLATION OF NEW SERVICES OR THE EXTENSION OF EXISTING SERVICES

REQUIRES CUTTING OF EXISTING FLOORS, WALLS, PARTITIONS, ETC., CHECK FOR THE PRESENCE

OF EXISTING MECHANICAL, PLUMBING AND ELECTRICAL SERVICES WITHIN OR IMMEDIATELY

BENEATH CONSTRUCTION. EXERCISE NECESSARY PRECAUTIONS TO PREVENT DAMAGE TO THE

SERVICES OR INJURY TO PERSONNEL DUE TO CONTACT WITH SAME. TEMPORARILY DISCONNECT

SERVICES DURING THE CUTTING OPERATION. SCHEDULE SERVICE OUTAGES IN ADVANCE WITH

THE COR.

9. EXCEPT AS OTHERWISE NOTED, LOCATE ALL ROOM THERMOSTATS 46 INCHES ABOVE FINISHED

FLOOR ON SAME HORIZONTAL CENTERLINE AS LIGHT SWITCH. WHERE LIGHT SWITCH AND

THERMOSTAT ARE ADJACENT TO EACH OTHER, LIGHT SWITCH SHALL BE CLOSEST TO THE DOOR.

COORDINATE WITH ELECTRICAL CONTRACTOR. NOTIFY THE ENGINEER OF ROOMS WHERE THE

ABOVE LOCATION CANNOT BE MAINTAINED OR WHERE THERE IS A QUESTION ON LOCATION.

10. RECOVER REFRIGERANTS FROM REFRIGERATION EQUIPMENT IN ACCORDANCE WITH AHRI AND EPA

STANDARDS. PLACE RECOVERED REFRIGERANT IN CONTAINERS LABELED IN ACCORDANCE WITH

ARI AND EPA STANDARDS AND TURNED OVER TO THE COR.

11. RECYCLE MERCURY SWITCH THERMOSTATS THAT ARE REMOVED. DELIVER RECYCLED

THERMOSTATS TO PARTICIPATING WHOLESALERS.

12. INFORMATION SHOWN ON THE MECHANICAL DRAWINGS PERTAINING TO EXISTING CONDITIONS HAS

BEEN OBTAINED FROM AVAILABLE BUILDING DRAWINGS OR GENERAL FIELD OBSERVATIONS AND

MAY NOT INDICATE ACTUAL EXISTING CONDITIONS IN DETAIL OR DIMENSION. EXISTING

CONDITIONS ARE SHOWN IN AN APPROXIMATE WAY ONLY. THE CONTRACTOR SHALL BE

RESPONSIBLE FOR DETERMINING THE ACTUAL EXISTING CONDITIONS PRIOR TO DEMOLITION OR

PERFORMANCE OF ANY WORK. SHOULD CONDITIONS BE DISCOVERED THAT PREVENT EXECUTION

OF THE WORK AS INDICATED, OR THERE IS A QUESTION REGARDING SCOPE OF WORK OR LIMITS

OF DISTURBANCE, THE CONTRACTOR SHALL IMMEDIATELY NOTIFY THE COR IN WRITING AND

AWAIT WRITTEN DIRECTION BEFORE PROCEEDING WITH THE WORK.

13. REMOVE ALL EXISTING PIPING, DUCTWORK, EQUIPMENT, AND MATERIALS NOT REQUIRED FOR RE- USE OR RE-INSTALLATION (SHOWN OR OTHERWISE). ALL EXISTING MATERIALS AND EQUIPMENT

WHICH ARE REMOVED AND ARE DESIRED BY THE COR, OR ARE INDICATED TO REMAIN THE

PROPERTY OF GOVERNMENT SHALL BE DELIVERED BY THE CONTRACTOR WHERE DIRECTED BY

THE COR. ALL OTHER MATERIALS AND EQUIPMENT WHICH ARE REMOVED SHALL BECOME THE

PROPERTY OF THE CONTRACTOR AND SHALL BE REMOVED BY THE CONTRACTOR FROM THE

PREMISES.

14. DISCONNECT EXISTING PIPING NO LONGER REQUIRED TO REMAIN IN SERVICE (SHOWN OR

OTHERWISE) AND REMOVE PIPING BACK TO SERVICE MAINS UNLESS OTHERWISE INDICATED OR

NOTED ON PLANS. REMOVE EXISTING PIPE HANGERS, SUPPORTS, VALVES, ETC. CAP, PLUG, OR

SEAL EXISTING PIPING INDICATED OR REQUIRED TO REMAIN IN SERVICE OR IN PLACE. NO

EXISTING PIPING SHALL BE LEFT UNSEALED. VALVE ALL TERMINATED PRESSURE PIPE.

15. EXISTING MECHANICAL PIPING, DUCTWORK, EQUIPMENT, AND MATERIALS AFFECTED BY

DEMOLITION OR NEW WORK INSTALLATION AND REQUIRED TO REMAIN IN SERVICE SHALL BE RE- INSTALLED OR SUPPORTED AS REQUIRED IN ACCORDANCE WITH THE SPECIFICATIONS. ALL WORK

SHALL BE COMPLETED TO THE SATISFACTION OF THE COR AND AT NO ADDITIONAL CONTRACT

COST.

16. REMOVE ALL ACCESSORIES, CONTROLS, ENCLOSURES, SUPPORTS, HANGERS, PADS, ETC.

ASSOCIATED WITH ALL EQUIPMENT SHOWN TO BE REMOVED. REPAIR AND PAINT DAMAGED

SURFACES AND ALL SURFACES BEHIND ALL EQUIPMENT SHOWN TO BE DEMOLISHED TO MATCH

EXISTING ADJACENT SURFACES.

GENERAL:

1. COORDINATE CONTROLS WITH VRF SYSTEM MANUFACTURER.

2. BOTH SYSTEM THERMOSTATS SHALL OPERATE IN EITHER HEATING OR COOLING MODE.

OCCUPIED MODE (0700 TO 1800 ADJUSTABLE):

1. DURING OCCUPIED HOURS, SYSTEM IS STARTED AUTOMATICALLY BY PROGRAMMABLE

THERMOSTAT AND FAN OPERATES CONTINUOUSLY.

2. WALL MOUNTED PROGRAMMABLE THERMOSTAT, T-1 MAINTAINS SPACE TEMPERATURE AT

75 DEGREES F FOR THE COOLING CYCLE AND 72 DEGREES F FOR THE HEATING CYCLE

THROUGH MANUFACTURER'S SUPPLIED CONTROLS.

UNOCCUPIED MODE (1800 TO 0700 ADJUSTABLE):

1. DURING UNOCCUPIED HOURS, SYSTEM CYCLES ON WHEN SPACE TEMPERATURE AT T-1

FALLS BELOW 62 DEGREES F. WHEN SPACE TEMPERATURE AT T-1 RISES TO 65

DEGREES F, SYSTEM CYCLES OFF. WHEN SPACE TEMPERATURE AT T-1 RISES ABOVE 85

DEGREES F, SYSTEM CYCLES ON. WHEN SPACE TEMPERATURE AT T-1 FALLS TO 82

DEGREES F, SYSTEM CYCLES OFF.

HUMIDITY CONTROL:

1. IF SPACE RELATIVE HUMIDITY RISES ABOVE 60% AND SPACE TEMPERATURE AT T-1 IS

ABOVE 75 DEGREES F, SYSTEM COOLING IS ON. WHEN SPACE RELATIVE HUMIDITY FALLS

BELOW 60% OR SPACE TEMPERATURE AT T-1 FALLS BELOW 75 DEGREES F, HUMIDITY

CONTROL CYCLES OFF.
