Automatic vent
If the liquid temperature falls below the ambient
temperature or if the pump is installed outside,
condensation may form in the motor during inactivity.
In this case, make sure that the drain hole in the
motor flange is open and points downwards. See the
figure below.

If twin-head pumps are used for pumping liquids with
a temperature below 0 °C (32 °F), condensed water
may freeze and cause the coupling to get stuck. The
problem can be remedied by installing heating
elements. For pumps with motors smaller than 11 kW,
the pump must be installed with the motor shaft in
horizontal position.
4.2
Mechanical installation
The pump must be installed according to
national water regulations and standards.
4.2.1 Lifting the product
DANGER
Overhead load
Death or serious personal injury
‐ The lifting eyes fitted to large pump
motors can be used for lifting the pump
head (motor, motor stool and impeller).
Do not use the lifting eyes for lifting the
entire pump and motor assembly.
‐ TPD: Do not use the centrally
positioned thread of the pump housing
for lifting purposes as the thread is
placed below the centre of gravity of
the pump.
Pumps without lifting eyes must be lifted by means of
nylon straps.
