SHAFT
When the pump has been assembled, check that the shaft rotates freely and without noise.
7. FROST PROTECTION
Pumps which are not in operation during frost periods are to be drained to avoid frost damage.
Remove the plug (3) at the bottom to empty the pump. Alternatively, it is possible to use anti-freeze
liquids in normal constructions.
8. DISMANTLING
Before dismantling the pump make sure that it has stopped. Empty the pump of liquid before it
is dismantled from the piping system. If the pump has been pumping dangerous liquids you are
to be aware of this and take the necessary safety measures.
If the pump has been pumping hot liquids, take great care that it is drained before it is
removed from the piping system.
9. START-UP
A centrifugal pump will not function until it has been filled with liquid between the foot valve and
somewhat above the impeller of the pump.
The liquid also serves as coolant for the shaft seal. In order to protect the shaft seal the
pump must not run dry.
