Variable Speed Pump Installation and User’s Guide
Pump Reassembly
1. When installing the replacement shaft seal, use
silicone sealant on the metal portion before pressing
into the seal plate as shown. Note: Use extreme
care when applying sealant. Be sure no sealant
contacts the seal plate surface or the ceramic seal.
Allow sealant to cure overnight before reassembling.
2. Before installing the rotating portion of the seal into
the impeller, be sure the impeller is clean. Use a
light density soap and water to lubricate the inside
of the seal. Press the seal into the impeller with
your thumbs and wipe off the ceramic and carbon
faces with a clean cloth.
3. Remount the seal plate to the motor.
4. Grease the motor shaft thread and screw impeller
onto the motor shaft.
5. Screw in the impeller lock screw (counterclockwise
to tighten).
6. Remount the diffuser onto the seal plate. Be sure
the plastic pins and holding screw inserts are
aligned.
7. Grease the diffuser o-ring and seal plate gasket
prior to reassembly.
8. Assemble the motor subassembly to the pump
housing by using the two (2) through bolts for proper
alignment. Do not tighten the through bolts until all
six (6) bolts are in place and finger tightened.
Note: Ensure that the seal plate gasket is properly
seated inside of the pump assembly. The seal
gasket can be pinched between the seal plate
and the pump housing while tightening these six
screws, preventing a proper seal and producing a
slow leak when the pump is restarted.
9. Reinstall the drive onto the top of the motor.
10. Fill the IntelliFlo
®
Variable Speed Pump with water.
Drive Assembly Removal and Installation
To remove the drive and control panel from the motor
assembly:
1. Be sure all electrical breakers and switches are turned
off before removing the drive.
2. Disconnect the RS-485 communication cable
from the pump.
3. Open the keypad cover.
4. Remove the three Phillips head screws securing the
drive to the motor assembly as shown on the next
page.
5. Lift up the drive assembly and remove it from the
motor adapter located on top of the motor assembly.
Note: Be careful not to remove the gasket and orange
post caps located between the drive and motor. The
gasket is critical in keeping moisture out of the drive
and motor and should be replaced if damaged. Do
not reassemble with a damaged or missing gasket
or post-caps.
11. Reinstall the pump lid and plastic clamp. See
“Cleaning the Pump Strainer Basket” on page 20
for details
12. Reconnect the RS-485 communication cable to
the pump.
13. Prime the pump; refer to “Priming the Pump” on
page 4.
To avoid electrical hazard, do not remove the four
tamper proof screws from the motor assembly.
To avoid dangerous or fatal electrical shock
hazard, switch OFF power to motor before working
on pump or motor.
