•
For long periods of storage the pump must be protected against moisture and
heat.
•
Make sure the cooling jacket is empty before storing the pump.
•
After a long period of storage, inspect the pump before putting it into operation.
Make sure that the impeller can rotate freely. Pay special attention to the
condition of the shaft seals and the cable entry.
4.2 Storage in the pit-system not in use
If an installed pump is not in operation for an extended period of time, the insulation
resistance should be measured and the pump runs for 30 mins each month.
If the pump cannot be run due to lack of water in the sump it should be inspected and
turned over by hand each month & prior to being put back into service. If the
insulation resistance drops below 10 Mega-Ohm, contact your local Grundfos office.
The power source must be shut off and isolated at the control panel when the pump is
not in service
If the pump is disconnected from the control panel when not in service, the cable end
should be tightly sealed.
5. INSTALLATION
5.1 Points for attention during installation
•
Check that the dimensions of the sump are correct and large enough so that the
pump can be installed and removed for servicing.
•
Thoroughly clean and remove all rubbish from the sump and general
installation area to prevent clogging the impeller causing possible motor failure.
•
Check the accessories and controls are complete.
•
Carry the pump only as described in Clause 3.
•
The extra nameplate supplied with the pump should be fixed at the installation
site.
•
All safety regulations must be observed at the installation site, for instance the
use of blowers for fresh air supply.
•
Prior to installation, check the oil level in the oil chamber.
•
The start and stop levels are specified during the design stage. Always check
that the start/stop levels function and possibly alter them when commissioning
the pump in order to ensure good operation .
•
To ensure adequate pull-out strength we recommend to use anchor bolt.
