Start-up procedure
After pump installation, the system can be
started by using the following procedure:
• Fill water tank
• Open one tap
• Turn on pump
• Close tap once water begins flowing
• Open each additional tap until all air
has been purged from system
• Pump will shut off after taps are
closed and pressure builds to the set-
point of the pressure switch
Other electrical devices, eg switch, circuit
breaker, must be installed between the
pump and the positive (+) lead on the bat-
tery (on the red wire).

* 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.
Self-priming
Pump is self-priming up to m/6 ft. for
WPS 3.4 and .5 m/8. ft. for WPS 5.0.
Intake lines must be air-tight to ensure self-
priming.
dry running
Pump will not be damaged by shorter
period of dry running. It will, however, un-
necessary reduce your battery power.
caution
Do not use pump for any other liquids than
fresh-water and sea-water.
Temperature
Max liquid temperature: +50°C/+0°F
Max ambient temperature: +60°C/+40°F
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:
. Drain water storage tank.
. Open all taps.
3. Run pump until remaining water is
expelled.
4. Disconnect inlet and outlet tubes.
5. Refill tank with potable water.
6. Open all faucets and run until
bleach has been purged.
