Installation
Pump installation
Run the cables so that they do not have any
sharp bends and are not pinched.
Connect the discharge connection and motor
cable. See “Electrical connections”.
Lower the pump into the sump.
Place the pump on a base which will prevent it
from sinking into a soft sump bottom. Alternati­
vely, the pump can be suspended by its lifting
handle just above the sump bottom.
NOTE!
Where required by local au
-
thorities an acceptable motor-
circuit switch or other discon-
necting device shall be provid-
ed at the time of installation.
NOTE!
At certain installations and
operation points on the pump
curve the noise level 70 dB,
noise level speciied for the
actual pump, can be exceeded.
Transportation and storage
The pump may be transported and stored in a
vertical or horizontal position. Make sure that it
cannot roll or fall over.
WARNING!
Always lift the pump by its
carrying handle or lifting eyes,
never by the motor cable or
the hose.
WARNING!
Before starting to work on the
pump or moving the pump,
make sure that the pump is
isolated from the power sup-
ply and cannot be energized.
This applies to the control cir-
cuit as well.
The pump is frostproof as long as it is operating
or is immersed in the liquid. If the pump is taken
up when the temperature is below freezing, the
impeller may freeze. The pump shall be operated
for a short period after being taken up in order
to expel all remaining water.
A frozen impeller can be thawed by allowing the
pump to stand immersed in the liquid for a short
period before it is started. Never use a naked
lame to thaw the pump.
For longer periods of storage, the pump must be
protected against moisture and heat. The impel­
ler should be rotated by hand occasionally (for
example every other month) to prevent the seals
from sticking together. If the pump is stored for
more than 6 months, this rotation is mandatory.
After a long period of storage, the pump should
be inspected before it is put into operation. Pay
special attention to the seals and the cable entry.
Follow the instructions under the heading “Be­
fore starting”
WARNING!
Make sure that the pump can-
not roll or fall over and injure
people or damage property
