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.
s 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: The pump requires no lubrication.
Draining
Should the pump be subject to freezing temperatures, it will be necessary
to drain the pump completely. To drain, remove the drain plug located at
the bottom of the front face of the pump casing and the priming plug and
make sure that the drain hole is not restricted. After all the water has been
drained, operating the pump for a few seconds will ensure that the impeller
is devoid of water (make sure that the suction line is also devoid of water).
Pump Storage
Drain liquid from pump to prevent freezing. It is recommended that a good
rust inhibitor be put in the liquid end to prevent excessive corrosion. Be sure
motor is kept dry and covered. When restoring the use of the pump, replace
all plugs and make sure all connections are tightly sealed. After a complete
check is made, make the initial prime according to the OPERATION section.
Disassembly
(See figure 8 from the REPLACEMENT PARTS section.)
1. Shut o 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 (8, 10) to allow the pump to drain.
4. Remove the four bolts (9), the casing (11), the gasket (12) and O-ring (6).
5. Remove the screws on the diuser (7) to separate the diuser
(13) from the motor adapter (3). Remove the cap (16) and insert a
screwdriver to prevent the shaft from turning while unscrewing the
impeller (5). If impeller cannot be turned by hand, insert a flat object
into the impeller vane.
NOTE: Use a strap wrench on the impeller eye to
remove the impeller.
6. Slip the rotating seal (4) o the impeller hub.
7. To replace the seal seat (4A) remove four bolts to remove the case
adapter (3) to separate from the motor (2). Push the seal seat (4A)
out of the case adapter from the motor side.
Reassembly
1. Clean all the parts thoroughly before assembling.
2. Lightly lubricate (with soapy water) the rubber cap on the ceramic
seal (4) and push it into the adapter (3) using your 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 with the four bolts
removed previously.
4. Lubricate the rotating seal (4) (with 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 installing impeller.
5. Replace the impeller (5) and the diuser (13).
6. Replace the casing (11) making sure that the gasket (12) and O-ring (6)
are 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 the pump and check for leaks.
