Pump Reassembly/Seal Replacement
1. Install the
spring end
of the mechanical seal onto the
impeller shaft. Be sure
black/carbon
face is facing
outward.
2. Remount the seal plate to the motor using the four
(4) lock washers and four (4) nuts.
3. With the white ceramic face facing outward, press the
seal into the seal plate with your thumbs and wipe
off the ceramic with a clean cloth. Do not lubricate
seal faces.
4. Hand tighten impeller onto the motor shaft.
5. Screw in the impeller reverse lock screw (counter-
clockwise to tighten).
6. Install the rear plastic cover on the back of the
motor.
7. Remount the diffuser onto the seal plate. Make
sure the plastic pins and holding screw inserts are
aligned (see “TOP” indicator).
8. Assemble the motor subassembly to the housing.
Do not tighten the nuts and washers until all
four (4) motor bolts are in place. Using a torque
wrench, install and tighten the four nuts to a torque
value of 100 in-lbs (maximum). Do not overtighten
the nuts.
9. Reinstall the drive onto the top of the motor.
10. Fill the IntelliFloXF
®
Variable Speed Pump with
water.
11. Reinstall the pump lid and locking ring; see
“Cleaning the Pump Strainer Basket” on page 20.
12. Prime the system. See page 4 for priming
instructions.
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 control panel cover.
4. Remove the three Phillips head screws securing the
drive to the motor assembly as shown.
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 between
the drive and motor; it is critical in keeping moisture
out of the drive and motor. Replace the gasket if
damaged. Do not reassemble with a damaged or
missing gasket.
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.
