2 Safety
The manufacturer shall not bear any liability
for damages caused as a result of non-
observance of this documentation.
2.1 Correct and proper use
•Only use this pump for the purposes of
conveying the agreed pumping media.
•Comply with operating limits.
•The water may not contain any abra-
sive or long-fibered components that
may damage the pump materials.
Consult the manufacturer if using other
media.
•Ensure that the pump is only commis-
sioned with pumping medium and is
not operated without it.
•Open the suction-side fitting, and do
not use it to control the flow rate.
•Never operate the pump when the ar-
mature on the delivery side is closed.
•To avoid damaging the motor, observe
the permitted number of times per
hour that the motor can be switched
on (→Manufacturer information).
•Any other use must be agreed with the
manufacturer.
•The temperature of the pumping me-
dium must not exceed 40 °C.
Avoiding obvious misuse (examples)
•Observe the operating limits of the
pump for temperature, pressure, flow
rate and speed.
The main areas of use are:
•Water supply to single-family and mul-
tiple-family homes
•Water supply to businesses and agri-
culture
•Sprinkling and irrigation of gardens
and other usable areas
The pump is self-priming after being filled
once with water.
Do not operate the pump without water. Dry
running can lead to damage to the pump.
Ensure that the foot valve is in the water at all
times.
WARNING
Any use that goes beyond the purposes
described above shall be considered im-
proper use. OSNA shall bear no liability for
any resulting damages. The owner bears
full risk for improper use.

6.2 Installation
6.2.1 Installing the pump
Prior to installation, remove the packaging (if
present) and check the pump for any transport
damage. Ensure that the installation area is
dry and free of frost.
CAUTION
Do not operate the pump in areas where
there is a risk of explosion. Ensure that the
pump is installed and connected in line
with the local regulations.
We recommend installing the pump on a
noise-insulating base, in order to prevent
transmission noises to parts of the building.
