PUMP PREPARATION
Optional hose kits, designed specifically for this pump, are available
from your Honda dealer. See page 20.

Suction Hose Connection

If using a commercially available hose, ensure it is the same size or
larger than the suction port diameter (3 inches). To prevent the hose
from collapsing, use a hose that is reinforced with a non-collapsible
wall or braided wire construction.
Keep the pump as close as possible to the pumping liquid. Avoid hose
bends and sharp turns. Pump performance is best when the pump is
not far above the liquid level and the hose is kept straight.
Self-priming time is also proportional to the suction hose length. Using
a longer suction hose will increase the self-priming time.
Tighten the hose connector to the suction hose with a hose clamp to
prevent air leakage and loss of suction. Verify that the connector
sealing washer is installed and in good condition. A loosely connected
suction hose will reduce pump performance and self-priming ability.
The strainer provided with the pump should be attached to the end of
the suction hose as shown.
Always install the strainer on the end of the suction hose before
pumping. The strainer will prevent debris from entering the pump that
can cause clogging, diaphragm and/or other pump damage.

Discharge Hose Connection

If using a commercially available hose, a short, large diameter hose
will provide lower fluid friction and improve pump output. A long or
small diameter hose will increase fluid friction and reduce pump
output. Never use a hose size smaller than the discharge port
diameter (3 inches).
NOTICE
If a discharge hose is used that has a smaller inside diameter than the
port size, the pump case may be damaged. To avoid pump damage,
always use the correct size hose.
Tighten the hose clamp to prevent the hose from disconnecting under
high pressure.

Pump Priming

Pump priming is not required if the vertical distance from water to the
pump (suction head) is less than 16 feet. The suction head can be
increased to 24 feet if the pump is primed.
To prime the pump, remove the air cushion chamber cap. Grasp the
suction hose next to the suction fitting and lift the hose about 1 foot off
the ground. Lifting the suction hose will help to ensure the water goes
into the pump housing and not out the suction hose.
Pour about 1 gallon of water into the pump case through the air
cushion chamber. Lay the hose back on the ground, and reinstall the
air cushion chamber cap.

FREQUENCY OF USE

If your equipment will be used on an infrequent or intermittent basis,
(more than 4 weeks before next use), please refer to the Fuel section
of the STORAGE chapter (page15) for additional information
regarding fuel deterioration.
