6.2 Start-up after a long time of inactivity
The end cover incorporates a plug which can be re-
moved by means of a suitable tool. It is then possible
to free the pump rotor if it has seized up as a result
of inactivity. If the pump has been drained, it must be
filled with liquid before start-up, see fig. 9.
7. Service
Note: If a pump has been used for a liquid which is
injurious to health or toxic, the pump will be classi-
fied as contaminated.
If Grundfos is requested to service the pump, Grund-
fos must be contacted with details about the pumped
liquid, etc. before the pump is returned for service.
Otherwise Grundfos can refuse to accept the pump
for service.
Possible costs of returning the pump are paid by the
customer.
However, any application for service (no matter to
whom it may be made) must include details about
the pumped liquid if the pump has been used for liq-
uids which are injurious to health or toxic.
