4. Use extreme care when handling the mechanical seal. The mating seal surfaces are polished and are easily

damaged.

5. The mechanical seal can be changed without disconnecting piping by removing 4 bolts (see item 14 on page 9) and

pulling the motor with pump seal plate and impeller assembly away from front pump housing body.

6. Remove impeller and rotating portion of seal by holding motor shaft and rotating the impeller counter-clockwise

when facing the shaft extension on the motor.

7. The rotating portion of the seal can now be removed from the impeller. Clean the impeller hub and lubricate with

soapy water. Wipe off shining carbon sealing surface of new mechanical seal with a clean tissue to remove oily
fingerprints or other foreign materials. The new rotating seal can be pressed back onto the impeller.

8. To remove the stationary ceramic seal seat, first loosen the four motor bolts which run through the entire length

of the motor into the seal plate. Remove the seal plate from the motor. Press the ceramic seat and rubber gasket
out of the seal plate.

9. Clean the seal plate seal area and lubricate with soapy water. Press the new ceramic seal and gasket into the seal

plate, being sure it is fully seated. Wipe off the ceramic sealing surface with a clean tissue to remove oily fingerprints
or foreign substances.

10. Place the seal plate on the motor and carefully align the four motor through bolts. Secure the seal plate onto the

motor being careful not to overtighten the bolts. Gradually bring bolts up to final tightness by moving across in a criss-
cross pattern.

11. Check the position of the mechanical seal set in the seal plate and ensure the motor shaft is in the center of the seal

set.

12. Screw the impeller with new rotating seal onto the motor shaft. Rotate the motor shaft to make sure the impeller

is not touching the seal plate.

13. Clean the seal plate “O” Ring and check to make sure it is in position. Replace the motor and seal plate on the front

pump housing body and bolt into position with 4 bolts. Gradually bring bolts up to final tightness by moving across
in a criss-cross pattern.

14. Refer to initial start-up procedures to restart the pump.

SECTION V. WINTERIZING PROCEDURE

NOTICE

Allowing the water to freeze in pump will damage the pump and cause potential water damage/flooding and potential property
damage.

1. Drain all water from pump housing and piping when freezing temperatures are expected. A drain plug is provided

to drain the pump. If the pump has a strainer pot both the strainer drain plug and the housing drain plug should be
removed. If pump has no strainer pot then only remove the housing plug.

2. If the pump can be removed and placed in an inside dry location this should be done.

3. For an outdoor unprotected location it is best to protect the equipment in a weatherproof enclosure.

4. Do not wrap the motor with plastic because condensation could form inside the motor.

5. In installation where the pump cannot be drained a 40% propylene glycol 60% water solution will protect

to -50° F.

NOTICE

Do not use anti-freeze solutions except propylene glycol, as other anti-freeze is highly toxic and will damage the pump.
