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. Disconnect suction hose from water
supply (sea water supply) or if water
supply is taken from a tank, drain water
storage tank.
2. Open all spray nozzles/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. Spray nozzles/taps shall remain open
and pump fittings shall remain discon-
nected 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.
