1. THE LEAD LF PUMP SHALL ENERGIZE WHEN LINE PRESSURE DROPS BELOW 40 PSI. IF LINE FLOW IS LESS THAN 85 GPM, THE PUMP SHALL BE OPERATED AT THE MINIMUM FLOW SET POINT UNTIL LINE PRESSURE REACHES 60 PSI AND DE-ENERGIZED. IF FLOW IS GREATER THAN 85 GPM, THE PUMP SHALL BE OPERATED TO MAINTAIN A LINE PRESSURE OF 50 PSI. THE MINIMUM FLOW SET POINT SHALL BE 85 GPM. THE MINIMUM FLOW SET POINT CAN BE LOWERED IF NECESSARY TO KEEP PUMP STARTS BELOW 6 STARTS PER HOUR AT OPERATORS DISCRETION, BUT SHALL NOT BE SET BELOW THE MINIMUM PUMP SPEED (APPROXIMATELY 60 GPM @ 40 PSI) 2. IF FLOW IS GREATER THAT 85 GPM AND THE LEAD LF PUMP CANNOT MAINTAIN 50 PSI, THE LAG LF PUMP SHALL BE ENERGIZED AND BOTH PUMPS SHALL BE OPERATED TO MAINTAIN 50 PSI. IF LINE FLOW DROPS BELOW 120 GPM. THE LEAD LF PUMP SHALL BE DE-ENERGIZED AND BECOME THE LAG LF PUMP. THE PUMPS SHALL BE ALTERNATED AFTER EACH PUMP CYCLE. 3. IF THE LEAD AND LAG LF PUMPS ARE MAXIMUM SPEED AND CANNOT MAINTAIN A LINE PRESSURE OF 50 PSI, BOTH LF PUMPS SHALL BE DE-ENGERGIZED AND THE LEAD HF PUMP SHALL BE ENERGIZED. IF SYSTEM PRESSURE CONTINUES TO DROP, THE HF LAG PUMP SHALL BE ENERGIZED. IF LINE PRESSURE CONTINUES TO DROP, THE EMERGENCY LINE PUMP SHALL BE ENERGIZED. THE HF PUMP(S) SHALL BE OPERATED UNTIL LINE PRESSURE REACHES 55 PSI AND DE-ENERGIZED. THIS HF PUMPS SHALL OPERATE IN ATRI-FLEX CONFIGURATION AFTER EACH PUMP CYCLE,, THE LEAD HF PUMP SHALL BECOME THE EMERGENCY LAG PUMP. THE EMERGENCY LAG PUMP SHALL BECOME THE LAG PUMP, AND THE LINE PUMP SHALL BECOME THE LEAD PUMP. 4. THE WELL PUMPS SHALL BE OPERATED ON STORAGE TANK LEVELS AND SHALL BE OPERATED IN A LEAD/LAG DUPLEX CONFIGURATION TO MAINTAIN A MAXIMUM TANK LEVEL AS DETERMINED BY THE OPERATOR. THIS MINIMUM DISTANCE BETWEEN THE STORAGE TANK LEAD/LAG FLOAT SET POINTS SHALL BE 2 FEET, CONSULT THE OPERATOR ON DESIRED FLOAT SET POINTS. 5. THE AUTO-DIALER SYSTEM SHALL BE SET TO NOTIFY PLANT PERSONNEL OF ANY ABNORMAL OR EMERGENCY OPERATING CONDITION. COORDINATE WITH THE OPERATOR FOR DESIRED NOTIFICATION PARAMETERS. 6. SEE ELECTRICAL SHEETS FOR ADDITIONAL PLC/AUTO-DIALER INFORMATION. 7. SEE NOTE 10 ON SHEET E-2 FOR ADDITIONAL EMERGENCY POWER PARAMETERS.
