Start-up procedure

• 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
setpoint of the pressure switch
Self-priming
Pump is self-priming up to 2 m/6 ft. for
WPS 2.4. 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/+120°F
Max ambient temperature:
+60°C/+140°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:
1. Drain water storage tank.
2. Open all taps.
3. Run pump until remaining water is
expelled.
4. Disconnect inlet and outlet tubes.
5. Run pump briefly to confirm that
water has been expelled.
6. Taps shall remain open and pump
fittings shall remain disconnected until
temperatures are above freezing
Never start a frozen pump. Even if it is
drained it might contain a small amount of
frozen water that locks the rotor.
