Operation
Pump Set Up
1. Disconnect the pump from the tow vehicle by
turning the tongue jack handle clockwise to raise
the tongue from the hitch.
2. Block the wheels to prevent the unit from rolling.
3. Disconnect all safety chains, surge brake cables,
and the trailer wiring harness.
4. Lower the rear leveling jacks from the travel
position. Turn the jack handles clockwise until the
leveling feet are in firm contact with the ground.
Adjust the jacks until the pump is as level as
possible.
5. Attach fittings to both the intake and outlet
openings of the pump, verifying they match the
fittings on the hoses. Verify that a gasket/seal is in
place between the pump volute and the flange on
the attached fitting.
6. Tighten all hardware completely to maintain an
airtight seal. Threaded fittings require the use of
pipe thread sealant.
7. Attach a rigid hose/pipe to the intake (suction) side
of the pump.
NOTE: For best performance, the suction hose/piping
should be at least as large as the pump flange, never
smaller.
NOTE: The pump should be at the highest point of the
hose/piping.
NOTE: All suction piping and fittings should be checked
for any foreign material (rocks, bolts, wire, etc.) and also
any sharp burrs that could disrupt the flow.
Figure 3-48. Pump Seals
NOTE: Verify the O-ring seal is present in the fitting on
the pump before attaching the fitting. Lubricate the O-ring
seal with grease to maintain an airtight seal.
NOTE: The suction and discharge pipe/hose material
must be compatible with the liquid being pumped. Hoses
used on a suction line must be of the reinforced type to
prevent collapse under suction lift.
NOTE: If a manual shutoff valve is installed in the
discharge line, it must be open during operation.
8. Attach a rigid intake screen or strainer to the end of
the suction hose before placing it in the liquid. This
will prevent large items or excessive trash from
entering the pump housing.
NOTE: The intake screen must have enough openings
to equal 28 sq. in. (181 sq. cm) or more (6 in. pump). The
