(4) Attaching the delivery nozzle (outlet)
• Make a fixing hole of Ø21 or less for
attaching the nozzle. The hose attached at
the nozzle should be 1.8 m or less and
should reach without any strain, therefore
care should be taken in deciding on the best
position.
• Fix the nozzle (outlet) in place and attach on
the discharge side of the pump.
(5) Attaching the hose
• Attach the hose from the strainer to the pump
inlet.
• Attach the delivery nozzle hose to the pump
outlet.
• Make the hose as short as possible and
avoid sharp bends.
(6) Test operation
• Collect water in the bottom of the boat, and
check for any problems with the hose or
siring. After doing this, connect the battery.
• Turn on the pump switch, and check to see
that water is being taken in and discharged
properly. The pump will stop automatically
when there is no water left.
• If the inside of the pump is dry, or if the water
is not being drawn up initially after a period of
10 seconds, lift the strainer above the water
surface and stop the pump. Prime the pump
before starting it up again.
(7) Fixing the strainer
• After the test operation, fix the strainer into
place with screws.
(Be careful not to damage the bottom of the
boat with the screws.)
