* The wire length is the total distance from the
battery to the pump and back to the battery.
It is recommended to use a relay with a light
wire from main cable to switch to shorten the
main leaders.

Start-up procedure
After pump installation, the system can be
started by using the following procedure:
• Make sure suction hose is connected
Red
to the water supply.
• Open the spray nozzle and start
the pump.
• Close the spray nozzle when water
begins flowing and all air has been
purged from the system.
• If additional spray nozzles or taps are
in use after the pump, open each
additional nozzle/tap until all air has
been purged from the system.
• Pump will cut off after taps are
closed and pressure builds to the
setpoint of the pressure switch
Self-priming
Pump is self-priming up to .5 m/8. ft. for
WD 3.4 and 3 m/9.8 ft. for WD 5.0. Intake
lines must be air-tight to ensure self-pri-
ming.
dry running
Pump will not be damaged by shorter
0.6
period of dry running. It will, however, un-
3.9
necessary reduce your battery power.
caution
Do not use pump for any other liquids than
fresh-water and sea-water.

Winterizing
If water is not drained from the system
during freezing temperatures, damage is
likely to be sustained in the plumbing and
in the pump. To prevent damage follow
the instructions beneath:
. Disconnect suction hose from water
supply (sea water supply) or if
water supply is taken from a tank,
drain water storage tank.
