B. Pump Reassembly/Seal Replacement; see Section V, Technical
Data, Figure 4.
1. When installing the replacement shaft seal, use silicone
sealant on the metal portion, before pressing into the seal
plate.
2. Before installing the ceramic section of the seal into the
impeller, be sure the impeller is clean. Use a light density
soap and water to seal the seal. Press the seal into the
impeller with your thumbs and wipe off the ceramic and
carbon faces with a clean cloth.
3. Remount the seal plate to the motor.
4. Grease the motor shaft thread and screw impeller onto the
motor shaft.
5. Screw in the impeller lock screw (counter-clockwise to tighten).
6. Remount the diffuser onto the seal plate. Make sure the plastic pins and holding screw inserts are
aligned.
7. Grease the diffuser O-ring and seal plate gasket or O-ring prior to reassembly.
8. Grease the bolt threads, assemble the motor sub-assembly to the strainer pot-pump body by using the
two through bolts for proper alignment. Do not tighten the through bolts until all 6 bolts are in place and
finger tightened.
9. Fill the pump with water.
10. Reinstall the pump lid and plastic clamp; see SECTION II. START-UP.
11. Reprime the system.
C. The Shaft Seal.
1. The Shaft Seal consists primarily of two parts, a rotating member and a ceramic seal.
2. The pump requires little or no service other than reasonable care, however, a Shaft Seal may
occasionally become damaged and must be replaced.
CAUTION
The polished and lapped faces of the seal could be damaged if not handled with care.
CAUTION
In mild climate area, when temporary freezing conditions may occur, run your filtering equipment all night to prevent
freezing.
SECTION IV. RESTART INSTRUCTIONS.
A. If pump is installed below the water level of the pool, close return and suction lines prior to opening hair and
lint pot on pump. Make sure to re-open valves prior to operating.
CAUTION
DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this
occurs, the damaged seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If
the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the
pump to run dry, resulting in a damaged seal.
Note
Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.
