recommended that 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.
Pressure Gauge: A pressure gauge is not supplied with the pump. It
should be installed into the 1/8" NPT hole on the front of the casing on
the same side of the pressure switch.
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:
Open discharge valve on service line and nearby tap to monitor
water flow.
1.
Pour clean water through priming plug opening at top of casing
until water starts flowing out the vent plug hole.
2.
Install enclosed vent plug and tighten loosely with a wrench.
3.
Continue filling pump until water flows out of the priming hole.
4.
Install enclosed priming plug and hand-tighten.
5.
Start pump. If a tap is visible, you may see a short discharge of
water lasting 5 to 10 seconds.
6.
Run the pump for two minutes and then shut it off. Remove the vent
plug and priming plug.
7.
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.
8.
Once the pump begins pumping water continuously, firmly tighten
the vent plug and priming plug with a wrench.
9.
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
WARNING
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.
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.
REPLACING MECHANICAL SEAL (Figure 3):
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 the water system to release the pressure.
3.
Remove the drain and fill plugs to allow the pump to drain.
4.
Remove the bolts (1) and remove casing (2).
5.
Remove fan shroud fasteners from the motor and remove the fan
shroud (3). CAUTION: Care must be taken not to damage the motor
fan or shroud.
6.
Remove the impeller (4) by firmly holding on to the motor fan (5)
and turn the impeller in a clockwise direction.
7.
Slip rotating seal (9) off the shaft.
8.
Remove motor tie bolts and remove motor (6) from adapter (7)
by slightly tapping end of motor shaft with a mallet.
9.
Remove the adapter plate and the O-ring.
Reassembly:
1.
Clean all parts thoroughly before assembling.
CAUTION: Do not use petroleum-based cleaners or lubricants.
CAUTION: Care must be taken not to contaminate the ceramic
seal face.
2.
Lightly lubricate (soapy water) the rubber cap on the ceramic seal
(8) and push it into the adapter (7) using thumbs only. Make sure the
smooth surface of the ceramic seat faces outward.
CAUTION: Do not use petroleum-based cleaners or lubricants.
CAUTION: Care must be taken not to contaminate the ceramic
seal face.
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 the motor (6) to the adapter. Align the tabs of the
adapter plate with the slot at the bottom of the motor housing.
4.
Lubricate the rubber components of the rotating seal (9) (soapy
water) and slip it on to the shaft with the 'carbon' ring towards the
ceramic seat. CAUTION: Care must be taken not to contaminate the
carbon seal face.
5.
Replace the impeller (4) and the shroud with fasteners. Lubricate
and replace the O-ring.
