Installation Manual
START UP:
Before operating the pump for the first time, check the following:
1. Is motor correctly wired for voltage in use? Warranty is void if motor is damaged due to improper electrical hook-up.
2. If a magnetic starter is used, see that the heater element is sized for the Service Factor load of the motor otherwise
nuisance tripouts may occur.
3. IMPORTANT: Couplers must be properly aligned and coupler inserts must be fully engaged in the hubs (no teeth show-
ing). Check alignment and spacing before and after initial start-up. Check the set screws on each coupler hub to ensure
that they are tightened securely.
4. Before starting motor, ascertain that pump is filled with water to lubricate the seal. Do not operate pump dry for motor
checkout.
LUBRICATION:
Pump is equipped with permanently lubricated ball bearings. Lubricate motor per instruction label attached to motor.
SEAL REPLACEMENT:
Seals used in these pumps are Type 21 design (see Photo A). Some models manufac-
tured between 2004 and 2008 used the Type 2100 design (photo B). These designs are
interchangeable.
To replace the water seal, the following steps must be observed:
1. Disconnect electrical connections. Relieve system pressure and drain water from body.
2. Remove motor assembly from bracket and bracket from pump body.
3. Place bracket in vertical position, impeller up and loosen screw at center of impeller
two turns (
7
⁄
16
Hex Head). This screw has a left-hand thread. Tap impeller at its out-
side diameter with handle of hammer to free tapered fit between shaft and impeller
and completely remove screw, washer and impeller (see Figure 2 on reverse side of
this Instruction Sheet).
4. Remove the complete rotating element, which includes the retainer, rubber bellows, carbon and spring (it may be nec-
essary to pry these components loose using a screwdriver). Remove the stationary seat from the recess in the end of
the bracket (again it may be necessary to pry it loose with a screwdriver, see Figure 3 on reverse side).
5. Thoroughly clean shaft sleeve and seat cavity.
