CENTRIFUGAL FAN (FORCED DRAFT): 40 HP AT 480 VOLT 3 PHASE.

PONY MOTOR: 10 HP AT 480 VOLT 3 PHASE.

BASIN HEATER: 10KW, 480 VOLT 3 PHASE, PROTECTION TO -20°F.

PROVIDE STAINLESS STEEL WATER BASIN.

UNIT DIMENSIONS: LENGTH:17'-8". HEIGHT:11'-3". WIDTH:7'-10".

CT2 COOLING TOWER (COUNTER FLOW)

CAPACITY: 780 GPM AT 96.2°F EWT. 86°F LWT. 78°F WB.

CENTRIFUGAL FAN (FORCED DRAFT): 40 HP AT 480 VOLT 3 PHASE.

PONY MOTOR: 10 HP AT 480 VOLT 3 PHASE.

BASIN HEATER: 10KW, 480 VOLT 3 PHASE, PROTECTION TO -20°F.

PROVIDE STAINLESS STEEL WATER BASIN.

UNIT DIMENSIONS: LENGTH:17'-8". HEIGHT:11'-3". WIDTH:7'-10".

NEW WORK CODED NOTES:

1. PROVIDE NEW 8" EQUALIZER LINE BETWEEN CT1 AND CT2.

2. PROVIDE NEW SELF REGULATING HEAT TRACE (8 W/FT, 120V/1PH) ON

ALL CS PIPING AND ON CR PIPING.

3. INSULATE ALL CS AND CR PIPING BETWEEN COOLING TOWERS AND PIT

FLOOR. PROVIDE EMBOSSED ALUMINUM COVER.

4. PROVIDE VFD FOR 40 HP MOTOR. INSTALL IN BASEMENT BOILER ROOM.

COORDINATE VOLTAGE AND PHASE WITH NEW ELECTRICAL

DISCONNECTS AND SWITCHES.

5. NEW ISOLATION VALVE IN VERTICAL PORTION OF CR PIPE.

6. PROVIDE NEW HEAT TRACE CONTROLLERS IN THIS LOCATION.

CONNECT TO (2) EXISTING ELECTRICAL CIRCUITS. MAKE CONNECTION

TO BUILDING AUTOMATION SYSTEM TO PROVIDE ALARM IN THE EVENT

OF CABLE FAILURE.

7. PROVIDE NEW COOLING TOWER WATER LEVEL CONTROLLER IN THIS

LOCATION. MAKE CONNECTION TO NEW LEVEL INDICATOR IN TOWER

AND TO EXISTING MAKE UP WATER VALVE.

8. NEW ISOLATION VALVE IN HORIZONTAL PORTION OF CS PIPE.

DEMOLITION CODED NOTES:

1. REMOVE CS LINES AND CR LINES BACK TO POINT WHERE THEY

PENETRATE PIT FLOOR. LEAVE ENOUGH EXISTING PIPE EXPOSED FOR

CONNECTION TO REPLACEMENT PIPES.

2. REMOVE COOLING TOWER DRAIN AND OVERFLOW PIPES.

3. DISCONNECT MAKEUP WATER LINE FROM COOLING TOWER. EXISTING

MAKEUP VALVE ASSEMBLY TO REMAIN FOR REUSE. REMOVE WATER

LEVEL INDICATOR AND CONTROLS.

4. REMOVE ALL INSULATION FROM EXISTING CS AND CR PIPING

(APPROXIMATELY 120 LINEAR FEET). REMOVE HEAT TRACE.

5. REMOVE COOLING TOWERS.

6. REMOVE CR VALVE IN VERTICAL PORTION OF PIPE.

7. REMOVE TWO HEAT TRACE CONTACTORS AND ASSOCIATED CABLE.

8. REMOVE COOLING TOWER WATER LEVEL CONTROLLER.
