Harm to health

‐ Do not use antifreeze solution if
you use the pump for public or
potable-water supply.
After draining the pump during long shutdown
periods under freezing conditions, blow out all
liquid in passages and air pockets using
compressed air. You can prevent freezing of
pumped liquid by filling the pump with antifreeze
solution.
2. Rotate the shaft by hand monthly to coat the
bearings with lubricant and delay oxidation and
corrosion.
3. Where applicable, follow the motor manufacturer's
storage recommendations.
Do not tighten the vent screw or refit
the drain plug until the pump is to be
used again.
