5. Characteristic Curve (see figure 2a + 2b)
6. Installation Advice
The installation of a stop valve upstream and downstream of the pump is
recommended so the pump can be replaced at a later time without the
need to completely drain the system.
7. Installation
Figure 3: Only install in dry, frost-proof rooms in one of the permitted
fitting positions.
Figure 4: The use of type WD-B thermal insulation shells, available from
the manufacturer, is recommended when a thermal insulation
of the pump is required. When using other materials, leave the
motor housing uninsulated, otherwise the electronics may
overheat and the pump may automatically switch off.
Screw connections for installing the pump in the system are not included
in the scope of delivery, but they may be ordered as accessories from the
manufacturer.
Use new gaskets (included in the scope of delivery) when installing the
pump.
The customer must take appropriate isolation measures and provide
appropriate acoustic insulation to reduce possible noise transfer.
7.1 Electrical connection (see figure 7)
ATTENTION
The unit may not be installed in areas where there is a
danger of explosion and may not be used to pump
flammable liquids.
The unit may only be connected by an authorized
electrician. The pump is equipped with a factory installed
cable.
In case of changing the connection, it must be made as
shown in figure 7. The pump requires a separate circuit
breaker installed on the phase with a rated value of 10A.
The socket must be positioned in such way that no water
can drip onto it even in the event of damage to the piping.
