WIRING
The pump should be wired to an overload protected electrical distri bu tion panel (circuit breaker or fuse panel) with marine grade copper
stranded wire, sized to match the recommendation in the Electrical Specifications chart. The electrical circuit breaker (or fuse) must also be
sized to match the Electrical Specifications recommendation. Connect the motor's orange wire lead to positive and the black lead to negative.
Make all connections with mechanical locking type connectors such as crimp type butt connectors. Once the wiring is completed, the electri-
cal wires should be secured to a solid surface every 18" (46 cm) along the length of their run to prevent movement and abrasion.

* The length of run is the total length of both positive and negative conductors measured from the positive power source to the pump and back to negative.

SERVICE
If sludge should become lodged anywhere in the system, it
can cause excessive vacuum or pressure on the pump that may
damage the flexible impeller. If this occurs pump performance
will be reduced and it will become necessary to change the
pump's impeller.
Before performing any service work, ensure the system's security
valve is closed and the power to the pump is turned off and
labeled "Do Not Turn On" to guard against it being accidentally
turned back on while service work is being performed.
IMPELLER REPLACEMENT
To change the impeller, remove the pump end cover screws, end
cover and O-ring. Grasp the impeller's hub with a pair of pliers and
pull the old impeller from the impeller bore.

With a rotary motion (to flex the blades of the new impeller under
the cam silhouette in the pump body) push the new impeller into
the body until the flat of the impeller insert aligns with the flat of
the shaft. When the two flats align, push the impeller firmly into
the impeller bore until it bottoms in the bore. Place the end cover
O-ring seal in the O-ring groove in the body. (A small amount of
grease may be used to hold it in place.) Position the end cover
against the body and secure it with the end cover screws.
SEAL REPLACEMENT
Discharge
Under normal circumstances, the shaft seal should function prop-
counter
erly for several hundred hours of operation. If the seal should ever

develop a leak and needs to be replaced, begin the procedure
by following the above instructions for changing an impeller.
Once the impeller has been removed, remove the two screws that
secure the pump head to the motor and pull the pump body off
of the motor shaft. Using a piece of 1/2" (12.7mm) wood dowel
(or similar material) from the back (motor) side of the body push
against the seal to dislodge it from the seal bore.
When the seal is removed, ensure the seal bore is clean of all de-
bris. From the front (impeller) side of the pump housing, place the
new seal in the seal bore, ensuring the lip of the seal is pointing
toward the impeller bore and press the seal into the seal bore
until it is firmly seated in the bottom of it. Guide the motor shaft
through the lip seal and resecure the pump body to the motor end
bell. With this complete, the impeller, O-ring and end cover can be
re-installed per the above instructions for impeller replacement.
