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.

Installation
The unit may not be installed in areas where there is a
danger of explosion and may not be used to pump
flammable liquids.
Figure 3: Only install in dry, frost-proof rooms in one of the permitted
fitting positions.
The use of 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. 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.

installed cable.
The PWM wire must be connected to the controller with
the right polarity mentioned. ( see figure 6 )
The pump requires a separate circuit breaker installed
