a) priming
NoTE: You will need enough water to fill the suction line and
casing. Priming time depends on distance from water source to
pump (5-15 min.).
Using an inline check valve:
1. Open discharge valve on service line and nearby tap to monitor
water flow.
2. Pour clean water through priming plug opening at top of casing
until water starts flowing out the vent plug hole.
3. Install enclosed vent plug, tighten loosely with a wrench.
4. Continue filling pump until water flows out of the priming hole.
5. Install enclosed priming plug, hand tighten.
6. Start pump. If a tap is visible you may see a short discharge of
water, which will last 5-10 seconds.
7. Run the pump for 2 minutes, and then shut it off. Remove the vent
plug and priming plug.
8. You have completed the first priming cycle, consisting of steps
2 to 7. This process will have to be repeated from 2 to 6 times,
depending on the length of your suction line. (Approximately one
priming cycle for every 5 feet of suction line.) Stop when the pump
begins to pump water continuously.
9. Firmly tighten the vent plug and priming plug with a wrench.
10. If the pump does not draw water within 8 tries, shut it off and check
for suction leaks.
Using a foot valve:
1. Open discharge valve on service line and nearby tap to monitor
water flow.
2. Pour clean water through priming plug opening at top of casing
until the suction line is full and water starts flowing out the vent
plug hole. You will need approximately 1liter of water for every 3
ft. of suction line.
3. Follow steps 3 through 6 above. If within 2 minutes water is not
being pumped continuously, stop the pump. Remove vent plug
Fig. 3
and priming plug. Repeat steps 2 through 6 above. If this does
not work, stop the pump and check the suction line for leaks.
4. Once the pump begins pumping water continuously, firmly tighten
the vent plug and priming plug with a wrench.
b) draining: Should the unit be subject to freezing, it will be necessary
to drain the pump and tank. To do this, shut off the power to the
pump at the main electrical service panel. Open a tap in the water
system to release the pressure. Remove the drain and fill plugs
from the pump casing. Remove the pressure tank drain plug (if
so equipped). Allow ample time for the system to drain before
reinstalling the plugs.
mAINTENANcE
WARNING - RISK oF ElEcTRIcAl ShocK
Before servicing motor-operated equipment, shut off the power
at the main electrical panel and disconnect the power supply
from motor and accessories. Use safe working practices during
servicing of equipment.
a) lubrication: The pump requires none. Refer to motor
manufacturer's instructions for motor lubrication.
b) cleanout plug: For applications where clogging is a problem, a
1/4" NPT plug has been provided for access to clean the nozzle/
venturi. This plug is located directly below the suction opening
in the front of the casing. ImpoRTANT! Before removing the
cleanout plug, shut off the power to the pump at the main
electrical panel. Open a tap in the water system to release
the pressure.
c) Replacing mechanical Seal (Fig. 3):
Only duly qualified persons should perform maintenance on
electrical and/or mechanical devices.
disassembly:
1) Shut off the power to the pump at the main service panel
and disconnect the power supply from motor.
2) Open a tap in the water system to release the pressure.
3) Remove the drain and fill plugs to allow the pump to drain.
4) Disconnect the tube leading to the pressure switch.
5) Remove the four bolts (1) and remove casing (2).
6) Pry the diffuser (4) out of the casing using two slotted
screwdrivers for leverage.
