2. Returning the product for service
If you request Grundfos to service the product, contact Grundfos
with details about the pumped liquid before returning the product.
Otherwise Grundfos can refuse to accept the pump for service.
Costs of returning the product are to be 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
product has been used for liquids which are injurious to health or
toxic.
2.1 Servicing pumps with explosion-proof motors
Service work on Ex pumps must be carried out by Grundfos or a
workshop authorised by Grundfos. Violation of this requirement
will invalidate the Ex classification of the pump.
Overhauled and repaired explosion-proof pumps are provided
with a repair plate giving this information:
• repair symbol R
• name of registered trade mark of the repairing workshop
• workshop reference number relating to the repair
• date of overhaul or repair.
In case of subsequent repairs, the existing repair plate should be
replaced by a new, updated repair plated and earlier markings
must be covered.
The repairing workshop must keep records of performed
overhauls and repairs together with records of all previous
overhauls, repairs and possible modifications. Copies of the
repairing workshop’s detailed records should be filed by the
owner or operator together with the original type certificate of the
explosion-proof motor in question.
3. Safety
For safety reasons, all work in pits must be supervised by a
person outside the pump pit.
Pits for submersible wastewater pumps contain wastewater with
toxic and/or disease-causing substances. Therefore, all persons
involved must wear appropriate personal protective equipment
and clothing and all work on and near the pump must be carried
out under strict observance of the hygiene regulations in force.
WARNING
Installation fault
Death or serious personal injury
- Pump installation in pits must be carried out by
specially trained persons.
- Work in or near wastewater pits must be carried
out according to local regulations.
CAUTION
Electric shock
Minor or moderate personal injury
- It must be possible to lock the mains switch in
position 0.
- Type and requirements as specified in EN 60204-
1, 5.3.2.
We recommend that you make all maintenance and
service work when the pump is placed outside the
pit.
Before attempting to lift the pump, make sure that the
lifting bracket is tightened. Tighten if necessary.
