2. A MANUAL LOCKING DEVICE HAS BEEN INSTALLED FOR THE MINIMUM OPEN POSITION OF 3HVR-AOD70.
WHILE A SINGLE FILTER UNIT IS OPERA TING.
3. 17000 CFM IS AN APPROXIMATION. THE ACTUAL FLOW RATE WILL BE THE RESULT OF THE DAMPER MINIMUM OPEN POSITION TO OBTAIN THE REQUIRED NEGATIVE PRESSURE,

4. 3HVR*FNIOA AND 3HVR*FNIOB ARE AXIAL FLOW FAN ASSEMBLIES EACH CONSISTING OF TWO AXIAL FLOW FANS INSTALLED IN SERIES 11,e. 3HVR*FN10Al AND 3HVR*FN10A2, 3HVR*FN10Bl AND 3HVR*FN!OB2 I WITH EACH FAN DRIVEN BY ITS OWN MOTOR.

MANUAL STARTS ARE INITIATED BY THE OPERATOR AS PLANT CONDITIONS REQUIRE THEM AFTER THE EQUIPMENT MANUAL START BLOCK SIGNAL IS REMOVED AT 40 SEC. DURING LOP CONDITIONS.
3. WHEN THE DIESEL GENERATOR BREAKER CLOSES CO SEC! ALL SAFETY RELATED MOTOR CONTROL CENTERS ON THE EMERGENCY BUS WILL BE ENERGIZED. ALL SWITCH-GEAR LOADS ARE STARTED IN ACCORDANCE WITH SEQUENCE CHART.

4. THE MANUAL STARTS ARE ADM IN IS TRA TIVEL Y CONTROLLED AND SOME REQUIRE BLOCKING SIGNAL RESETS IN ADDITION TO THE AUTOMATIC EQUIPMENT MANUAL START BLOCK SIGNAL REMOVED.

5. WHENEVER A SIS OR CDA OCCURS WITHOUT A LOP ALL REQUIRED EQUIPMENT IS ENERGIZED WITHOUT SEQUENCING DELAYS EXCEPT CONTAINMENT RECIRCULATION PUMP CCDA ONLYl

12. IF PUMP lA FAILS TO START, lC WILL START.5 SECOND LATER.

13. ADDITIONAL INTERLOCKS AND PERMISSIVES, ASSOCIATED WITH THE CONTROL BUILDING CHILLER, WILL IMPACT THEIR ACTUAL START TIME.
CONSIDERING THE SETPOINT AND TOLERANCES OF THE CHILLER PROGRAM TIMER AND CHILLED WATER PUMP TIMERS, THE ACTUAL START TIME OF THE CHILLER UNIT WILL BE BETWEEN 111 SECONDS AND 171 SECONDS AFTER DIESEL GENERATOR CIRCUIT BREAKER CLOSURE.
