2) and remove cover and O-Ring.
Disconnect wires from power cord
set (wires and connector are color
coded for reassembly). Turn pump

6. If replacing capacitor (single phase
only), remove wires from capacitor.
Remove capacitor.
Risk of electric
shock. Before
touching capacitor, discharge it by
shorting the terminals together with an
amber handled screwdriver.

3. Inspect seal plate O-Ring carefully;
replace if damaged. Place O-Ring in

passing seal over shaft shoulder and
snap ring groove shoulder. Seal faces
and ring must be clean and
undamaged or seal may leak, (See
