GENERAL NOTES :

1. THESE DRAWINGS ARE SCHEMATIC, AND ARE

NOT REPRESENTATIVE OF ALL POTENTIAL

CONDITIONS. CONTRACTOR IS RESPONSIBLE

FOR COORDINATION WITH ALL OTHER

DISCIPLINES TO ENSURE PROPER

INSTALLATION OF ALL SYSTEMS AND

EQUIPMENT.

HVAC CONTROLS NOTES:

1. EXISTING BUILDING AUTOMATION SYSTEM SHALL BE REUSED.

GRAPHICS SHALL BE UPDATED TO INCLUDE ANY ADDITIONAL

CONTROL POINTS INDICATED ON THE CONTRACT DOCUMENTS.

2. EXISTING BUILDING AUTOMATION SYSTEM (BAS) IS

MANUFACTURED BY CIRCON AND INSTALLED IN 2017.

3. THE EXISTING SEQUENCE OF OPERATION FOR THE EXISTING

WSHP UNIT SHALL REMAIN UNCHANGED.

4. SEQUENCE OF OPERATION:

A. THE HVAC SYSTEM IS CONTROLLED ON AN OCCUPIED AND

UNOCCUPIED MODE OF OPERATION. CONTRACTING OFFICER

SHALL CONFIRM HOURS OF OPERATION AND IF REQUIRED, IT

SHALL BE RE-PROGRAMMED.

B. CIRCULATING PUMPS P-1A AND P-1B SHALL BE OPERATED AS

LEAD/LAG AND ON A TIME SCHEDULED AS INDICATED BY THE

CONTRACTING OFFICER AND PROGRAMMED BY THE

CONTRACTOR.

C. DURING THE UNOCCUPIED MODE, THE SYSTEM SHALL BE

OFF. THE UNOCCUPIED MODE SHALL BE OVERRIDDEN IF 1.

THE OUTDOOR AIR TEMPERATURE FALLS BELOW 36°F

(ADJUSTABLE), THE LEAD PUMP SHALL START TO CIRCULATE

CONDENSER WATER THRU THE LOOP AND COOLING TOWER

(CCC-1). 2. ANY WSHP UNIT CALLS FOR COOLING OR

HEATING.

D. DURING THE OCCUPIED MODE, THE LEAD PUMP SHALL BE

STARTED, THE COOLING TOWER (CCC-1) FAN, AND SPRAY

PUMP SHALL BE ENABLED.

E. THE CONDENSER RETURN WATER TEMPERATURE (CWRT)

SHALL BE MAINTAINED AT 90°F (ADJUSTABLE). ON A RISE IN

CWRT ABOVE 90°F (ADJUSTABLE), CCC-1 FAN SPEED SHALL

MODULATE FROM LOW TO HIGH. ON A FURTHER RISE IN

CWRT, THE SPRAY PUMP SHALL BE ACTIVATED.

F. ON A FALL IN CWRT BELOW 90°F (ADJUSTABLE), CCC-1 AND

SPRAY PUMP SHALL REMAIN OFF. ON A FURTHER FALL IN

CWRT, THE BY-PASS VALVE SHALL MODULATE OPEN TO

MAINTAIN 90°F (ADJUSTABLE) CWRT.

G. SUMP PUMP HEATERS SHALL BE ENERGIZED IF THE SUMP

PUMP WATER TEMPERATURE FALLS BELOW 38°F

(ADJUSTABLE)

H. THE EXISTING BAS SHALL CONTINUOUSLY MONITOR THE

FOLLOWING:

1. PUMP P-1A AND 1B STATUS.

2. CONDENSER WATER SUPPLY AND RETURN

3. COLLING TOWER FAN STATUS

4. COOLING TOWER FAN SPEED.

5. SPRAY PUMP STATUS

6. SUMP PUMP WATER TEMPERATURE

7. SUMP PUMP HEATER STATUS.

8. OUTDOOR AIR TEMPERATURE AND HUMIDITY

COORDINATION FOR EQUIPMENT SHUTDOWN :

1. CONTRACTOR SHALL SUBMIT A

CONSTRUCTION SCHEDULE INDICATING

EQUIPMENT DELIVERIES, TIME SCHEDULE FOR

DEMOLITION, TIME SCHEDULE FOR

INSTALLATION OF NEW EQUIPMENT, AND

SCHEDULE FOR EQUIPMENT START-UP.

CONSTRUCTION SCHEDULE SHALL BE

APPROVED BY THE CONTRACTING OFFICER

PRIOR TO PROCEEDING WITH WORK.

2. EQUIPMENT INDICATED TO BE REMOVED SHALL

BE REMOVED FROM THE JOBSITE AND

DISPOSED OF PER STATE AND FEDERAL

REGULATIONS.
