Instruction and Maintenance Manual

8.3 PRECAUTIONS DURING STORAGE

1. The pump body may fracture if the water inside freezes; insulate the pump or remove
all the water from the inside.
2. If you have any spare pumps, you must perform test runs on them on a regular basis
and keep them ready for use at all times.
3. When a pump remains off for a long period of time, you must take great care to
prevent any oxidation on the surface of the bearing, shaft, coupling, etc. The gasket
may also become mouldy. To avoid this, remove the gasket, dry it and grease it and
then put it back in its position.
