3.1 Mechanical installation
When mounted on a base stand or brackets, the
pump must be installed outside the pit. An inlet line
must be connected to the pump.
A dimensional sketch for each individual installation
type can be found at the end of this booklet.
3.1.1 Lifting the pump
All lifting equipment must be rated for the purpose
and checked for damage before any attempts to lift
the pump. The lifting equipment rating must under no
circumstances be exceeded. The pump weight is
stated on the pump nameplate.
Carelessness during lifting or transportation may
cause injury to persons or damage to the pump.
For horizontal, dry-installed pumps, a special lifting
bracket can be ordered to ease the lifting of the
pump. See the service instruction on
www.grundfos.com.
Prior to installation, make sure that the pit
bottom is even.
WARNING
Electric shock
Death or serious personal injury
- It must be possible to switch off the
power supply and lock the main switch
in position 0 with a padlock to ensure
that the power supply cannot be
accidentally switched on.
- Any external voltage connection to the
pump must be switched off before
working on the pump.
The pump must not run dry. Dry running
can cause ignition hazard.
Install an independent secondary level
switch to ensure that the pump is stopped
in case the primary stop level switch is not
working.
Inspect the oil level and condition every
3000 operating hours or at least once a
year.
When the pump is new or after
replacement of the shaft seal, check the oil
level and water content after one week of
operation.
Use the lifting bracket only for lifting the
pump.
Do not use it to hold the pump when it is in
operation.
We recommend that you always use
Grundfos accessories to avoid
malfunctions due to incorrect installation.
WARNING
Crushing hazard
Death or serious personal injury
- Check that the screws of the lifting
bracket are tightened before attempting
to lift the pump. Tighten, if necessary.
- Always lift the pump by its lifting bracket
or by means of a fork-lift truck if the
pump is fixed on a pallet.
- Never lift the pump by the power cable
or the hose or the pipe.
WARNING
Electric shock
Death or serious personal injury
- Never lift the pump by the power cable.
