6. Startup

Before starting the pump, submerge the pump inlet
in the pumped liquid.
Open the isolating valve, if fitted, and check the level
switch setting.
The pump may be run briefly to check
Note
the direction of rotation without being
submerged in the pumped liquid.

7. Maintenance and service

Warning
Before starting any work on the
product, make sure that the power
supply has been switched off and that it
cannot be accidentally switched on.
Before carrying out maintenance and service, it must
be ensured that the pump has been thoroughly
flushed with clean water. Rinse the pump parts in
water after dismantling.
Check the pump and replace the oil once a year. If
the pump is used for pumping liquids containing
abrasive particles or it is operating continuously, the
pump must be checked at shorter intervals.
Warning
Out of consideration for the personal
safety and health, this work must be
carried out by specially trained
persons. Furthermore, all rules and
regulations covering safety, health and
environment must be observed.
Be careful during dismantling as you
will get access to sharp edges, etc.,
which may cause cuts. Wear protective
gloves.
A possible replacement of the cable or
the level switch must be carried out by
an authorised Grundfos service
workshop.

7.4 Contaminated pumps

If a pump has been used for a liquid
which is injurious to health or toxic, the
pump will be classified as
contaminated.
If you request Grundfos to service the pump, contact
Grundfos with details about the pumped liquid, etc.
before you return the pump 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
liquids which are injurious to health or toxic.
