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 interrupter (GFI) 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 (Refer to Figure 2):
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 Äll 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).
For Larger size motors remove rear cover and hold the
shaft using a Åat wrench inserted from the side, through
the opening in the end housing. Impeller has right-hand
thread. If impeller cannot be turned by hand, insert a
Åat 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
MAINTENANCE
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 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.
Preventative Maintenance:
At the end of the season, drain remaining water from
casing from the drain plug at the bottom and Åush the
pump out with clean water. Replace plug and Äll the
pump end with an R.V. (Recreational Vehicle) Antifreeze.
Ensure that the pump end is completely drained and
Åushed prior to priming in the new season.
PRECAUTIONS:
Whenever pump is dismantled and then reassembled, always
check to see that the impeller rotates freely within the diffuser.
