4.1 Mechanical installation

DANGER
Electric shock
Death or serious personal injury
- Before beginning the installation, switch off the
power supply and lock the main switch in position
0.
- Before working on the pump, switch off any
external voltage connected to the pump.
DANGER
Crushing
Death or serious personal injury
- During installation, always support the pump by
means of lifting chains or place it in horizontal
position to secure stability.
Fix the extra nameplate supplied with the pump at the installation
site.
Observe all safety regulations at the installation site, for instance
the use of blowers for fresh-air supply to the pit.
CAUTION
Crushing of hands
Minor or moderate personal injury
- Do not put your hands or any tool into the pump
inlet or outlet port after the pump has been
connected to the power supply, unless the main
switch has been locked in the 0-position.
- Make sure that the power supply cannot be
accidentally switched on.
Prior to installation, check the oil level in the oil chamber, see
section
9.3 Oil check and oil change.
We recommend that you always use Grundfos
accessories to ensure correct functioning.
If the installation has to be tested at a pressure
higher than 1.3 times maximum pump head, isolate
the pump from the installation before the test to avoid
damage to the pump.

4.1.1 Lifting the pump

S pumps weigh up to 17860 lb (8100 kg) without accessories.
It is therefore very important to use the right lifting equipment.
The pump weight is stated on the pump nameplate. See sections
and
7.6 Nameplates 11.3 Dimensions and
We recommend that you always use lifting equipment
that is rated for the load.
DANGER
Crushing hazard
Death or serious personal injury
- Always check the lifting bracket and chain for
corrosion or wear before lifting.
- Always lift the pump by the marked lifting points or
by means of a fork-lift truck.
DANGER
Crushing hazard
Death or serious personal injury
- Make sure the center of gravity is between the
fork-lift arms when lifting the pump.
The approximate center of gravity is marked with a
label attached to the transportation stand.
DANGER
Electric shock
Death or serious personal injury
- Never lift the pump by the power supply cables.
Lifting the pump by the power supply cables may result in electric
short circuit and risk of electric shock when the pump is
connected to the mains. The cables and cable entries may be
damaged, leading to loss of watertightness and consequent
severe damage to the motor.
If the pump is tilted more than 10 ° in any direction from its normal
position, the pump may lose its stability.
