a separate circuit be led from the distribution panel to the pump unit. A
ground fault circuit interrupter (GFCI) protected circuit should be used
for all electrical devices operating near water. Install a proper fused
disconnect switch in the line and make certain the wiring is adequately
sized and well insulated. Undersized wire between the motor and
the power source will adversely limit the starting and load carrying
abilities of the motor. Minimum wire sizes for motor branch circuits are
recommended in Table 1. For added safety, ground the pump and motor
to the well casing (if metal) or the ground in the distribution panel.
Air Volume Control: If no perma-pressure tank is used in the pressure
system, an air volume control must be used to maintain an air cushion
in the pressure tank. Refer to the pressure tank owner's manual for
instructions.
Pressure Relief Valve: A high pressure safety relief valve is
recommended at some point in the water system. Ensure its location is
near the discharge of the pump, in an area with adequate drainage. Be
sure to direct the valve so that any water flow could not spray toward
any electrical devices.
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 to 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.
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 and tighten loosely with a wrench.
4.
Continue filling pump until water flows out of the priming hole.
5.
Install enclosed priming plug and hand-tighten.
6.
Start pump. If a tap is visible, you may see a short discharge of
water lasting 5 to 10 seconds.
7.
Run the pump for two 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. Repeat this process 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.
Once the pump begins pumping water continuously, 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 of the vent
plug hole. You will need approximately 1 liter of water for every 3
feet 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
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.
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.
4.
Remove the pressure tank drain plug (if so equipped). Allow ample
time for the system to drain before re-installing the plugs.

WARNING
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.
LUBRICATION: The pump requires no lubrication.
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.
REPLACING MECHANICAL SEAL (Figure 2):
CAUTION: 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 water system to release the pressure.
3) Remove the drain and fill plugs to allow the pump to drain.
4) Remove the six bolts (1) and remove casing (2).
5) Pry the diffuser (3) out of casing using two slotted screwdrivers for leverage.
6) Remove fan shroud (4) and insert a screwdriver into the slot in
shaft to prevent it from turning while unscrewing impeller nut (5) in
counterclockwise direction.
7) Remove impeller (6) off the shaft using two slotted screwdrivers for
leverage.
8) Slip rotating seal (7) off the shaft.
9) Remove motor tie bolts (8) and remove motor (9) from adapter (10)
by slightly tapping end of motor shaft with a mallet.
10) Remove the ceramic seal seat (11) from adapter (10).
Reassembly:
1) Clean all parts thoroughly before assembling.
2) Lightly lubricate (soapy water) the rubber cap on the ceramic seal
(11) and push it into the adapter (10) using thumbs only. Make sure
the smooth surface of the ceramic seat faces outward.
NOTE: If the pump will remain out of service for longer than one
week, the seal components must be installed dry (no lubrication).
3) Reassemble motor (9) to adapter (10) using motor tie bolts (8).
4) Lubricate the rotating seal (7) (soapy water) and slip it onto the shaft
with 'carbon' ring towards ceramic seat.
5) Replace the impeller (6) and the diffuser (3).
6) Replace the casing (2) making sure that o-ring is not damaged and
is in place.
7) Replace drain and fill plugs.
8) Reconnect power.
