CAUTION: DO NOT run pump dry. Fill pump with water
before starting pump. Operating pump dry may cause damage to
pump and will void warranty.
A priming port plug is provided in the top of the casing to fill the
pump with water. Once filled and the priming plug replaced, the
pump will prime. The priming time depends upon the vertical and
horizontal distance between the pump and the water level.
1. Remove priming port plug from pump (Figure 7).
2. Open discharge valves and any hoses on discharge side of
pump.
3. Fill pump with water through the priming port on top of pump.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.
WARNING - RISK OF ELECTRICAL SHOCK
• Have an electrician provide electrical power to the motor.
• Motor must be grounded and terminal cover in place to reduce
electrical shock hazard.
• Keep motor operating area as dry as possible.
• A ground fault circuit interrupter (GCFI) protected circuit is
recommended for use with any electrical device operating near
water.
• Always disconnect power before servicing.
• Not investigated for use in swimming pool areas.
LUBRICATION:
a) The pump requires no lubrication.
b) For electric motor models, refer to instructions provided
by the motor manufacturer.
DISASSEMBLY (FIGURE 8):
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 four bolts (11) and remove casing (1).
5) Remove three screws to separate diffuser (3) from motor
adapter (2).
6) Remove cap (5) and insert a screwdriver to prevent the
shaft from turning while unscrewing the impeller (4). If
impeller cannot be turned by hand, insert a flat object into
the impeller vane. NOTE: Use strap wrench on impeller
eye to remove impeller.
7) Slip the rotating seal (13) off the impeller hub.
8) To replace seal seat (13A); remove bolts (10) to separate
the motor (9) from the motor adapter (2). Push seal seat
(13A) out of motor adapter (2) from motor side.
REASSEMBLY:
1) Clean all the parts thoroughly before assembling.
2) Lightly lubricate (soapy water) the rubber cap on the
ceramic seal (13A) and push it into the adapter using
thumbs only. Make sure the smooth surface of the ceramic
seat faces outwards.
NOTE: If the pump will remain out of service for longer
than one week, the seal components must be installed dry
(no lubrication).
3) Put the adapter back on the motor.
4) Lubricate the rotating seal (13)(soapy water) and slip it
onto the impeller hub with the 'carbon' ring towards the
ceramic seat. Apply thread locker to shaft threads prior to
Allow trapped air to escape for a few minutes, then add more
water until full.
4. Replace priming port plug and tighten with wrench, using
PTFE tape on pipe threads.
5. Start the pump. A properly primed pump should discharge
water without air at a consistent pressure. If the pump does
not produce water after five minutes, stop the pump, release
all pressure, remove priming port plug, add more water,
replace plug, and try again. Ensure that a foot valve is prop-
erly installed on the suction pipe (Figure 5).
MAINTENANCE
installing impeller.
5) Replace the impeller (4) and the diffuser (3).
6) Replace the casing (1) making sure that the gasket is not
damaged and is in place.
7) Reconnect the tubes to the casing and to the pressure
switch.
8) Reconnect the power.
9) Prime pump, start, check for leaks.
