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 tempera-
tures are above freezing.
Never start a frozen pump. Even if it is drai-
ned it might contain a small amount of frozen
water that locks the rotor.
