DISABLE SURGERY CHILLER #1 AT 7TH FLOOR TO LIMIT POTENTIAL LOAD ON PANEL 'DPHL71EQ'

(4) EXISTING PUMPS CONNECTED TO EXISTING PANEL 'DPHL71EQ' ARE INTENDED TO BE RE-FED TO MOTOR CONTROL CENTER 'MCC-HL71EQ'. HOWEVER, MCC WILL NOT HAVE SUFFICIENT SPACE UNTIL DEMOLITION OF EXISTING LOADS FROM AC-17/18. (2) PUMPS CAN BE RELOCATED BY REMOVING EXISTING SPARE UNIT AND EXISTING PROVISION AND PROVIDING NEW BREAKERS AS INDICATED. REMAINING (2) PUMPS MAY BE MAINTAINED ON EXISTING PANEL UNTIL FREE SPACE IS CREATED IN MOTOR CONTROL CENTER THROUGH DEMOLITION OF EXISTING LOADS. ALTERNATIVELY, AVAILABLE SPACE IN 'DPHL72EQ' MAY BE UTILIZED SO LONG AS SPACE IS MAINTAINED TO INSTALL THE NEW BREAKER FOR 'DPHL73EQ'. PUMPS SHALL BE SHUT- DOWN AND MOVED ONE AT A TIME UNLESS OTHERWISE DIRECTED BY VA FACILITIES. COORDINATE

SHUTDOWNS OF PUMPS WITH FACILITIES.

PROVIDE NEW EQUIPMENT AND FEEDERS FOR CONNECTION OF AIR-HANDLING UNIT 19.

A.

B.

C.

D.

CONNECT ALL AHU 19 FANS (SUPPLY, RETURN, AND OUTSIDE AIR) TO NEW PANEL 'DPHL75EQ'.

CONNECT NEW 480:208/120V-3PH-4W TRANSFORMER WITH INTEGRAL PANELBOARD 'LL75EQ' TO NEW PANEL 'DPHL75EQ' AND CONNECT ALL 120V OR 208V LOADS ASSOCIATED WITH AHU 19 TO NEW CIRCUIT BREAKERS

WITHIN PANEL.

RECONNECT EXISTING CHILLERS #1 AND #2 TO EXISTING PANEL 'DPHL71EQ' AT NEW LOCATION AS INDICATED

ON PLANS

PROVIDE NEW EQUIPMENT AND FEEDERS FOR CONNECTION OF AIR-HANDLING UNIT 18.

A.

REMOVE EXISTING PANEL 'EPE72-CR' TO FACILITATE INSTALLATION OF NEW AHU 18.

A.

CONNECT ALL AHU 18 FANS (SUPPLY, RETURN, AND OUTSIDE AIR) TO NEW PANEL 'DPHL74EQ'.

CONNECT NEW 480:208/120V-3PH-4W TRANSFORMER WITH INTEGRAL PANELBOARD 'LL74EQ' TO NEW PANEL 'DPHL74EQ' AND CONNECT ALL 120V OR 208V LOADS ASSOCIATED WITH AHU 18 TO NEW CIRCUIT BREAKERS

WITHIN PANEL.

DEMOLISH (2) EXISTING 350A-3P CIRCUIT BREAKERS IN PANEL 'DPHL72EQ' THAT PREVIOUS FED SUPPLY FANS IN DEMOLISHED UNITS AC 17 AND AC 18. INSTALL NEW 600AF/600AT, 3P CIRCUIT BREAKER IN NEWLY

CREATED SPACE.

INSTALL NEW PANEL 'DPHL73EQ' AND CONNECT COMPLETE TO NEWLY INSTALLED 600A-3P CIRCUIT BREAKER

IN PANEL 'DPHL72EQ'.

CONNECT ALL AHU 17 FANS (SUPPLY, RETURN, AND OUTSIDE AIR) TO NEW PANEL 'DPHL73EQ'.

CONNECT NEW 480:208/120V-3PH-4W TRANSFORMER WITH INTEGRAL PANELBOARD 'LL73EQ' TO NEW PANEL 'DPHL73EQ' AND CONNECT ALL 120V OR 208V LOADS ASSOCIATED WITH AHU 18 TO NEW CIRCUIT BREAKERS

WITHIN PANEL.

PROVIDE (2) NEW 600AMP FRAMES IN EXISTING PANEL 'DPHL71EQ' (FOR AHU 19 AND AHU 18). PROVIDE (1)

WITH 600AMP TRIP UNIT AND (1) WITH 400A TRIP UNIT.

UPGRADE EXISTING TRIP UNIT IN EXISTING SPARE 800A CIRCUIT BREAKER IN SUBSTATION 'E2'. REFER TO

ONE-LINE FOR ADDITIONAL DETAILS.

NOTE: DURING ANY SHUTDOWN OF SUBSTATION 'E2' TO FACILITATE NEW WORK, 'ATS-45' AND 'ATS-46' SHALL BE TRANSFERRED TO GENERATOR POWER TO MAINTAIN OPERATION OF EQUIPMENT CONNECTED TO THESE

TRANSFER SWITCHES (SURGERY AIR-HANDLING UNITS AND OTHER SURGERY EQUIPMENT).

PROVIDE NEW MANUAL TRANSFER SWITCH 'MTS-47' AT LOCATION AS INDICATED ON PLANS AND ALL ASSOCIATED CONTROLS AND NEW FEEDERS FROM NEW 600AF/400AT IN PANEL 'DPHL71EQ' AND EXISTING 800AF IN SUBSTATION 'E2' DISTRIBUTION SECTION. CONNECT NEW MANUAL TRANSFER SWITCH COMPLETE.

PROVIDE NEW DISTRIBUTION PANELBOARD EQUIPMENT MOUNTED IN AHU 19 VESTIBULE AND CONNECT

COMPLETE TO NEW FEEDER FROM LOAD SIDE LUGS OF NEW 'MTS-47'.

NOTE: DUE TO THE INSTALLATION LOCATION OF NEW PANEL 'DPHL75EQ' IN THE VESTIBULE OF AHU-19, PANELBOARD CANNOT BE INSTALLED UNTIL AHU 19 IS RIGGED INTO PLACE.

PROVIDE NEW DISTRIBUTION PANELBOARD 'DPHL74EQ' LOCATED IN PENTHOUSE ADJACENT TO NEW AHU 18 AND CONNECT COMPLETE TO PREVIOUSLY INSTALLED 600AF/600AT CIRCUIT BREAKER IN PANEL 'DPHL71EQ'.

VA SHUTDOWNS

DISCONNECTING PANEL 'EPE72-CR' WILL SHUTDOWN (6) EXISTING EXHAUST FAN LOADS (PER PANELBOARD DIRECTORY). CONTRACTOR SHALL IDENTIFY AREAS OF THE FACILITY THAT WILL BE AFFECTED BY THIS

SHUTDOWN AND NOTIFY VA COR AT LEAST (14) DAYS PRIOR TO SCHEDULED SHUTDOWN.

TRANSFER SWITCH OPERATIONS NOTES

NOTE: CONTRACTOR SHALL PROVIDE CONTROLS SUBMITTAL ALONG WITH TRANSFER SWITCH AND METERING SUBMITTALS, INCLUDING WIRING DIAGRAM, INPUT/OUTPUT REGISTER LISTS, PCB DIAGRAMS, ETC. AS NECESSARY TO DETAIL THE PHYSICAL IMPLEMENTATION OF THE CONTROL SCHEME INDICATED BELOW.

SUBMITTALS WILL BE REJECTED UNLESS CONTROLS SUBMITTAL IS PROVIDED.

TYPICAL OPERATION

'MTS-49' PRIMARY SOURCE (SOURCE A) SHALL BE CONSIDERED NORMAL POWER FEEDER FROM SUBSTATION 'E2'

'MTS-49' SECONDARY SOURCE (SOURCE B) SHALL BE CONSIDERED EMERGENCY EQUIPMENT BRANCH POWER

FEEDER FROM DISTRIBUTION PANELBOARD 'DPHL71EQ'.

'AHU 19' SHALL OPERATE ON SOURCE A UNLESS MANUALLY TRANSFERRED TO SOURCE B.

TRANSFER TO SOURCE B

MONITOR THE TOTAL THREE-PHASE DEMAND AMPERAGE (15 MINUTE WINDOW) ON THE LOAD FEEDER FROM

'ATS-44'.

• PROVIDE AN OUTPUT SIGNAL TO 'MTS-49' TO INHIBIT MANUAL TRANSFER TO SOURCE B WHEN THE DEMAND

AMPERAGE EXCEEDS 450A.

• PROVIDE AN OUTUT SIGNAL TO 'MTS-49' TO AUTOMATICALLY SHED TRANSFER SWITCH TO SOURCE A WHEN

THE DEMAND AMPERAGE EXCEEDS 770A.

COORDINATE NECESSARY SIGNAL REQUIREMENTS AND PROGRAMMING BETWEEN METER AND TRANSFER

SWITCH MANUFACTURERS.

WHEN CRITERIA IS MET TO ALLOW FOR A MANUAL TRANSFER TO SOURCE B, 'MTS-49' SHALL DELAY (30) SECONDS IN CENTER-OFF POSITION TO ALLOW UNIT'S MOTORS TO SPIN DOWN BEFORE TRANSFERRING TO SOURCE B.

RE-TRANSFER TO SOURCE A

DURING MANUAL OR AUTOMATIC RE-TRANSFER TO SOURCE A, 'MTS-49' SHALL DELAY (30) SECONDS IN CENTER- OFF POSITION TO ALLOW UNIT'S MOTORS TO SPIN DOWN BEFORE TRANSFERRING TO SOURCE B.

OUTPUT CONNECTIONS

PROVIDE BACNET/IP CONNECTION FROM 'MTS-49' TO BUILDING AUTOMATION SYSTEM (BAS). PROGRAM SYSTEM TO DISPLAY TRANSFER SWITCH POSITION, BY-PASS STATUS, INHIBIT TRANSFER STATUS, AND LOAD SHED

STATUS.

PROVIDE BACNET/IP CONNECTION FROM ELECTRIC POWER METER ON LOAD SIDE OF 'ATS-44' TO BUILDING AUTOMATION SYSTEM (BAS).
