Transportation And Storage; Installation - Grundfos SEN series Montage- Und Betriebsanleitung

3. Transportation and storage

The pump is supplied from the factory in proper packing in which
it should remain until it is to be installed.
Make sure that the pump cannot roll or fall over.
All lifting equipment must be rated for the purpose and checked
for damages before any attempts are made to lift the pump.
The lifting equipment rating must under no circumstances be
exceeded. The pump weight is stated on the pump nameplate.
Always lift the pump by its lifting bracket or by means
of a fork-lift truck, never by means of the motor cable
or the hose/pipe.
Note: Do not remove the protection from the free end of the sup-
ply cable until the electrical connections are to be made. The free
cable end must never be exposed to moisture or water, whether it
is protected or not. Non-compliance may involve the risk of dam-
age to the motor.
For long periods of storage, the pump must be protected against
moisture and heat.
Storage temperature: –30°C to +60°C.
After a long period of storage, the pump should be inspected
before it is put 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. Installation

The loose nameplate supplied with the pump should be fixed at
the installation site.
All safety regulations must be observed at the installation site,
e.g. the use of blowers for fresh-air supply to the pit.
Do not put your hands or any tool into the pump
suction or discharge port after the pump has been
connected to the electricity supply, unless the pump
has been switched off by removing the fuses or
switching off the mains switch. It must be ensured
that the electricity supply cannot be accidentally
switched on.
Prior to installation, check the oil level in the oil chamber, see
section 8.1 Oil check and oil change.
The SEN pumps are designed for various installation types.
Figures 3 to 6 show the possible installation types.

out and lowered into the pit by means of the guide rails.
