OPERATION

WARNING: DO NOT RUN THE PUMP BEFORE PRIMING IT. THE SEAL AND
IMPELLER COULD BE PERMANENTLY DAMAGED.
PRIMING
NOTE: You will need enough water to fill the suction line(s) and casing. Priming
time (5-15 minutes) depends on distance from water source to pump.
USING AN IN-LINE CHECK VALVE:
1. Open discharge valve on service line and nearby tap to monitor water
flow.
2. Fully open control valve by rotating counter-clockwise.
3. Pour clean water through priming plug opening at top of casing until water
starts flowing out.
4. Install enclosed priming plug, hand tighten.

5. Start pump. If a tap is visible, you may see a short discharge of water
lasting 5-10 seconds.
6. Run the pump for two minutes and then shut it off. Remove priming plug.
7. You have completed the first priming cycle, consisting of steps 3 to 6.
Repeat this process from 2 to 6 times, depending on the length of your
200'
suction line (approximately one priming cycle for every 5 feet of suction
8
line). Stop when the pump begins to pump water continuously.
8. Once the pump begins pumping water continuously, firmly tighten the
14
priming plug with a wrench.

9. Adjust the control valve (clockwise), so that the flow and pressure are
stable. (See double pipe installation instructions.)

10. If the pump does not draw water within 8 tries, shut it off and check for

suction leaks.

USING A FOOT VALVE:
SINGLE PIPE INSTALLATION
1. Fill suction pipe with water prior to connecting piping to pump. You will
need approximately 1 liter of water for every 3 ft. of suction line. NOTE: If
you are unable to fill the suction line, please use the directions above for
an in-line check valve.
2. Open discharge valve on service line and nearby tap to monitor water flow.
3. Fully open control valve (counter-clockwise rotation).
4. Pour clean water through priming plug opening at top of casing until water
starts flowing out.
5. Install enclosed priming plug, hand tighten.
6. Start pump. If a tap is visible, you may see a short discharge of water
lasting 5-10 seconds.
7. If water is not being pumped continuously within two minutes, stop the
pump. Remove priming plug. Repeat steps 4 to 6. If this does not work,
stop the pump and check the suction line for leaks.
8. Once the pump begins pumping water continuously, firmly tighten the
priming plug with a wrench.
DOUBLE PIPE INSTALLATION (Deep well application): Priming and setting the
discharge control valve.
Follow the single pipe installation procedures. Close the control valve (clockwise
rotation). If the pump is properly primed, pressure will build up immediately.
Open the control valve slowly (approximately 1 to 2-1/2 turns) until the pump
delivers maximum capacity as observed from an open tap nearest the pump.
Observing the pressure gauge while the pump is pumping continue to adjust
the control valve so that the pressure gauge reads approximately 25 PSI and
flow and pressure is stable.
DRAINING: Drain the pump and tank if either will be subjected to freezing
temperatures:
1. Shut off the power to the pump at the main electrical panel.
2. Open a tap in the water system to release the pressure.
3. Remove the drain and priming plugs from the pump.
