CAUTION:

After leak is repaired, dispose of old oil properly, and refill with new oil.

Pressure builds up extremely fast, increase pressure by "TAPPING" air

nozzle. Too much pressure can damage seal. DO NOT exceed 10 psi.

Oil Replacement - Set unit upright and refill with new cooling oil as per

table below. Fill to just above motor, but below capacitor as an air

space must remain in the top of the housing to compensate for oil

expansion. Apply pipe thread compound to threads of pope plug then

assemble to housing.

DO NOT overfill oil. Overfilling of housing with oil can create excessive

and dangerous hydraulic pressure which can destroy the pump and

create a hazard.

Overfilling oil voids warranty.

Impeller and Volute:

1. Disconnect Power

2. Remove cap screws, volute and gasket

3. Clean and examine impeller, for cracks or breakage and replace if required. To

remove impeller, place a flat screwdriver in the slot of the end of the shaft to hold

the shaft stationary while unscrewing.

4. Check v-ring and remove if damaged.

Power Cord and Motor:

5. Remove pipe plug and drain oil from housing.

6. Remove gland nut, washer and nylon housing from motor housing. Pull cord through

and disconnect the wires from the terminals on power cord.

7. Remove screws and washer and lift motor housing and stator from seal plate.

8. Remove o-ring, replace if damaged.

9. Check motor capacitor with an Ohm meter by first grounding the capacitor by placing

a screwdriver across both terminals and then removing screwdriver. Connect Ohm

meter (set on high scale) to terminals. If needle move to infinity then drifts back, the

capacitor is good. If needle does not move or moves to infinity and does not drift back,

replace capacitor.

10. Inspect motor winding for shorts and check resistance values. Check rotor for wear.

If rotor or the stator windings are defective, the complete motor must be replaced.
