All lifting equipment must be rated for the purpose and checked
for damage before any attempt to lift the pump. The lifting
equipment rating must under no circumstances be exceeded.
The pump weight is stated on the pump nameplate.

Note
The weights are net weights including the
accessories mounted from factory.
Warning
Always lift the pump by the marked lifting points
or by means of a fork-lift truck.
To make the use of a fork-lift truck when moving
a pump safer, the approximate centre of gravity is
marked with a label attached to the
transportation stand. Make sure the centre of
gravity is between the fork-lift arms when lifting
the pump.
Never lift the pump by the power supply cables.
It may result in electric short-circuit and risk of
electric shock when the pump is connected to the
mains. The cables and cable entry may be
damaged, leading to loss of watertightness and
consequent severe damage to the motor.

Warning
If during transportation, assembly or dismantling
the pump is tilted more than 10 ° in any direction
from its normal position (EN 809, 5.2.1.4), the
pump may lose its stability. Secure the pump by
means of chains or place it in horizontal position.
Warning
Make sure that the lifting brackets are tightened
before attempting to lift the pump. Tighten if
necessary. Carelessness during lifting or
transportation may cause injury to personnel or
damage to the pump.

5.3 Storage
For long periods of storage the pump must be protected against
moisture and heat.
Storage temperature: -20-55 °C. Maximum 70 °C for short
periods not exceeding 24 hours (EN 60204-1, 4.5).
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, O-rings
and the cable entry.
6. Installation
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 to the pit.
Prior to installation, check the oil level in the oil chamber, see
section 10.1 Oil check and oil change.
6.1 Installation types
S pumps, ranges 72, 74 and 78 are designed for various
installation types.
Figures 13 to 20 show the possible installation types.
Installation types C and S
Submerged installation on auto-coupling.
Fig. 13 Permanent installation in pit
The pump can easily be pulled out and lowered into the pit by
means of the guide rails. The stop level is lower for type C than
for type S. See fig. 13.
Fig. 14 Upper guide rail bracket
Fig. 15 Intermediate guide rail bracket; required if guide rails
are more than 6 m long
Correct pedestal height for installation on auto-coupling is
important in order to obtain the best efficiency for the pump.
Fig. 16 Auto-coupling base installation on pedestal
Caution
Do not remove the protection hose from the free
end of the supply or sensor cables until the
electrical connection is to be made.
Whether insulated or not, the free cable end must
never be exposed to moisture or water.
Non-compliance with this may cause damage to
the motor.
Caution
If the pump is being stored for more than two
months, the impeller must be turned by hand at
least every two months to prevent the lower
mechanical seal faces from seizing up. If not, the
shaft seal may be damaged when the pump is
started. If the impeller cannot be turned by hand,
contact an authorized service workshop.
Caution
Make sure the cooling jacket is empty before
storing the pump.
Warning
During installation always support the pump by
means of lifting chains or place it in horizontal
position to secure stability.
Warning
Before beginning the installation, switch off the
power supply and lock the main power switch in
position 0.
Any external voltage connected to the pump
must be switched off before working on the
pump.
Warning
Do not put your hands or any tool into the pump
suction or discharge port after the pump has
been connected to the power supply, unless the
main power switch has been locked in the 0-
position.
Make sure that the power supply cannot be
accidentally switched on.
Warning
We recommend that you always use Grundfos
accessories to avoid malfunctions due to
incorrect installation.
