14. Remove the carbon face seal half from the motor
shaft. This is a spring loaded seal. Grasp the
portion of the seal closest to the impeller body and
pull the seal off using a twisting motion.
15. Using two flat head screwdrivers, insert the ends
into the two side openings between the backplate
and the motor flange adapter plate. Slowly and
evenly leverage the backplate forward. Take care
not to damage the ceramic side seal.
16. For motors with a NEMA 182-184 JM frame, use
a 9/16" socket wrench to loosen the four (4) hex
screws securing the motor flange adapter plate to
the motor. For NEMA 213-215 JM frames, use a
3/4" socket wrench. Carefully pull away the motor
flange adapter plate avoiding any impact to the
motor shaft and set aside. See Figure 14.

Pump Assembly

1. Attach the motor flange adapter plate to the motor
assembly using the four sets of hardware (hex
screws, split washers, and flat washers). The flange
adapter plate is marked "TOP" to show the correct
orientation. Ensure the motor drive shaft is not
impacted during this operation.
2. Verify the two (2) dowel pins are inserted to assist
with aligning the Backplate.
3. Align the backplate with the mating alignment pins
in the adapter plate and with the front faced arrow
pointing downward. Push the backplate onto the
alignment pins until the back surface is flush with
the adapter plate. Lightly tap on the backplate front
face with a soft hammer or mallet if necessary.
4. Install the ceramic seal side by lubricating the seal
and cup with distilled water and soap solution.
Press the seal evenly and firmly down into the
seal pocket by hand. Do not use O-ring lubricant
to install this seal. Do not use any tools to press
the seal into the pocket. Clean the surface of the
ceramic with a nonabrasive cloth. Before installing
the spring seal, ensure the surface of the ceramic is
free of cracks, chips, and debris. If any damage is
observed, replace immediately.
5. Install the spring seal side by lubricating with
distilled water and soap solution. Do not use
O-ring lubrication to install this seal. Do not use
any tools to install this seal. Ensure the carbon
side of the seal is facing the ceramic side and the
rubber side is facing the impeller. By hand, slowly
press the seal onto the drive shaft sleeve until the
two seal surfaces nearly touch. The seal should
be uncompressed and hanging over the end of the
motor's drive shaft sleeve slightly.
6. Install the shaft key into the motor drive shaft slot.
Align the impeller's keyway with the drive shaft
key. Press the impeller onto the drive shaft. Secure
the impeller with the hex socket screw, split washer,
and flat washer. Slowly turn clockwise to tighten
the screw until tight. The impeller will slowly press
the two seal faces together and compress the spring
seal into the proper position.

Installation & Operation Manual
7. Attach the diffuser by aligning the arrow on the
diffuser's front face with the arrow on the backplate.
The diffuser should press onto the two alignment
pins located in the backplate. Secure the diffuser
using the hex bolts, split washer, and flat washer.
Place the diffuser O-ring into the groove around the
inlet. Ensure the O-ring is not damaged or twisted
during installation. Silicon O-ring lubrication may
be placed on the O-ring to assist with assembly of
the pump housing.
8. Install the backplate O-ring. Ensure it is not twisted.
Silicon O-ring lubrication may be placed on the
O-ring to assist with assembly of the pump housing.
9. Slide the Pump Housing onto the Motor Assembly
and secure with the four (4) sets of hardware (hex
screws, split washers, flat washers, and nuts).
Ensure the split washers are placed under the hex
nut..
10. Tighten the bolts lightly in a crossing "X" pattern
using a 15/16" wrench to draw the backplate to the
body in an even manner. Once all the bolts are snug,
tighten in the same order to 20 ft-lbs of torque.
11. Secure the Strainer Pot Assembly onto the
assembled Pump Housing with motor using the
eight (8) hex screws, split washers and flat washers.
Tighten the bolts lightly in a crossing "X" pattern
using a 15/16" wrench starting with the inner
(middle) four (4) and then the outer (top and
bottom) four (4) to draw the backplate to the body
in an even manner. Once all the bolts are snug,
tighten in the same order to 20 ft-lbs of torque.
12. If the pump is located above the water level of the
pool, remove the lid and fill the basket with water
before starting the pump. See "Strainer Pot Service"
section for details.
NOTE
around lid O-ring seat prior to replacing lid.
If any valves have been previously closed, reposition
each valve to avoid closure to the pump's discharge
also known as "Dead Heading". Trapped air in the
system can cause the filter lid to be blown off. This
can result in death, serious personal injury, or property
damage. Be sure all air is out of the system before
operating.
13. Hand-tighten the lid to make an air tight seal. Do
not use any tools to tighten the lid.
14. Ensure all drain plugs are installed and hand tight.
IMPORTANT NOTE: Failure to remove the
lid's center plug before service will significantly
increase the difficulty of assembling or
disassembling the lid and may cause the lid's lifting
tabs to break.
