Replacement Instructions

• Refer to Figure 2 and the associated parts list to identify the parts included in each replacement kit.

• Using a No. 1 Phillips screwdriver, remove the two (2) screws attaching the diffuser to the backplate. Carefully remove the diffuser from the backplate. See Figure 3.

• Remove any debris from the inlet and outlet of the impeller.

• Remove the motor shaft cover on the back of the motor by twisting the hex-head screw with an adjustable wrench. The motor shaft will be exposed.

• Hold the exposed motor shaft with a ½" wrench while removing the impeller center screw. Use a No. 2 Phillips screwdriver. Turn the left-handthreaded screw clockwise to loosen it.

• While holding the motor shaft with a ½" wrench, thread the new impeller onto the motor shaft. Hand-tighten the impeller until it is secure.

• Using a No. 2 Phillips screwdriver, tighten the impeller’s center screw into the center of the impeller. Turn the left-hand-threaded screw counter-clockwise to tighten it. Do not overtighten.

• Replace the motor shaft cover by inserting the cover tabs into the slots and rotating the cover 90º clockwise.

• Install the new diffuser over the impeller. Make sure you insert the alignment pins into the correct holes. The molded-in arrow must align with the molded-in arrow on the backplate. See Figure 3.

• Install the two (2) Phillips-head screws. Tighten the screws to draw the diffuser against the backplate.

• To avoid a leak, make sure the diffuser o-rings, o-ring grooves, and o-ring seal area are clean and free of debris. If grease is used to retain the o-rings, it must be silicone based. Do not use petroleum-based grease, because it will destroy the o-rings.

• If you are not installing another replacement kit, skip to Section 6, Pump Assembly.
