INSPECTION
Inspect all parts of the pump for wear or damage, and order replacements
as necessary. Check the shaft seal (12) carefully. Look for cracks in the
ceramic seat. Check the seal faces for wear and nicks. Flex the rubber parts
and check them for holes and cracks. Replace the complete seal if any part
is damaged, or if the seal leaks. Do not use old parts.
SHAFT SEAL REPLACEMENT
Take great care while handling the shaft seal (12) to avoid damage to
its carbon and ceramic sealing faces.
DO NOT USE OIL OR GREASE ON
THE SEAL PARTS,
because either may damage the thermoplastic
material of the pump through overheating
Plugged basket in skimmer or hair in lint strainer; Dirty filter; Impeller plugged.
‘’LOW PUMP PRESSURE’’
Check setting of dial valve; Pump running at reduced speed (see above);
Discharge valve or inlet fitting opened too much; Leakage of air into suction
system.
‘’HIGH PUMP PRESSURE’’
Discharge valve or inlet fittings closed too much; Return lines too small;
Dirty filter.
‘’NOISY PUMP AND MOTOR’’
Plugged basket in skimmer or hair in lint strainer; Defective motor
bearings; Valve in suction line partly closed; Suction line partly plugged;
Vacuum cleaner hose plugged or too small; Piping causing strain on pump
case; Impeller rubbing on pump case.
‘’LEAKAGE OF WATER AT SHAFT’’
Shaft seal requires replacement.
‘’AIR BUBBLES AT INLET FITTINGS’’
Leakage of air into suction line at connections; Cover of hair and lint strainer
not airtight; Restriction in suction line; Low water level in pool.
or chemical reaction. Make sure that the pump parts are clean, but be
careful not to scratch the surfaces that come into contact with the seal. . The
ceramic and it’s rubber housing must be installed moistened with water by
pressing them firmly by hand into the motor bracket (13). Make sure the flat
surface of the ceramic faces the pump body. Reassemble the pump
retracing the steps illustrated on page 5. Reinstall the pump and run it for 5
minutes to ensure that no water leaks from the pump case (which would
indicate improper seal installation). If any water is observed leaking from the
pump case, repeat seal installation procedure.
