Caution
Pump Damage!
Do not run the pumps without water in the system. Damage to
the pump seal will result if the pump is run dry for more for more
than a few seconds.
3. Confirm all H/O/A Switches are in the "Off" position. Turn control power
(On / Off) switch to "On".
4. Turn disconnects only, to "ON" position (panel door must be closed).
5. Jog each pump by turning the respective H/O/A switch momentarily to
the "HAND" position.
System Start-up
1. Verify that the system piping in the building can be pressurized. Open a
valve at the highest point to release the air in the system.
2. Close each individual pump discharge valve. Partially open Multi-purpose
Valve.
3. Turn Pump 1 H/O/A switch to the "Hand" position.
4. Slowly open Pump 1 discharge valve.
5. Fill the entire building system and observe the high point valve until all
the air is released and then close the valve.
6. Turn Pump 1 H/O/A switch to the "OFF" position.
7. Repeat steps C - F for Pump 2.
8. Check to determine if system pressure remains stable. Failure to main-
tain stable pressure may indicate an improperly operating check valve,
system leakage or entrapped air.
9. Turn all H/O/A switches to the "AUTO" position. The system is now oper-
ating in the fully automatic mode. All control devices can be exercised
and adjusted to field conditions if necessary.
10. The system is now ready for unattended automatic operation. The isola-
tion valves must be left fully open. The small suction and discharge pres-
sure gauge ball valves must be adjusted to dampen out gauge
fluctuations (and prolong gauge life), but must not be turned fully off or
the differential pressure switch will not monitor pressure changes.
