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.
PERFORM INSPECTIONS MONTHLY
1. Ensure pump is still securely bolted to the foundation.
2. To avoid any fire hazards, ensure that there is adequate clearance from
any combustible materials, shelving or cabinets. Ensure there are no
leaves or debris near the pump.
3. Ensure that the motor is securely wired into a proper GFCI-protected
circuit. Test the GFCI periodically by pressing the test switch when the
pump is operating. This should shut off the pump. If the GFCI does
not shut the pump off, have an electrician replace the GFCI as soon as
possible. Remember to reset the GFCI by pressing the reset switch.
4. Look for any signs of leaks in pipes. Replace or repair, if necessary.
5. Clean the exterior of the pump, if needed, with a solution of
vinegar and water.
DRAINING
Should the unit be subject to freezing, it will be necessary to drain the
pump and tank. To do this, shut off the power to the pump at the main
electrical panel. Open a tap in the water system to release the pressure.
Remove the drain and priming plugs from the pump casing. Remove the
pressure tank drain plug (if so equipped). Allow ample time for the system
to drain before reinstalling the plugs.
LUBRICATION
The pump requires none.
REPLACING MECHANICAL SEAL
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.
2. Open a tap in the water system to release the pressure.
3. Remove the drain (12) and prime plugs to allow the pump to drain.
4. Disconnect the tube leading to the pressure switch.
5. Remove the 4 bolts (1) and remove casing (2).
6. Pry the diffuser (4) out of the casing using two slotted
screwdrivers for leverage.
7. If the impeller cannot be turned by hand, insert a flat object into the
impeller vane (5).
8. Slip the rotating seal (7) off the shaft and remove the seal plate (8).
9. Remove the ceramic seal seat (9) from the seal plate.
(See Fig. 11)
Reassembly:
1. Clean all the parts thoroughly before assembling.
2. Lightly lubricate (soapy water) the rubber cap on the ceramic seal (9)
and push it into the seal plate 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 seal plate back on the motor.
4. Lubricate the rotating seal (7) (soapy water) and slip it onto the shaft
with the 'carbon' ring towards the ceramic seat.
5. Replace the impeller (6) and the diffuser (4).
6. Replace the casing (2), making sure 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 the pump, start, and check for leaks.
