4. Installation and assembly

4.1 Flushing out the heating system (with pump removed)

In order to avoid undesirable interruptions in operation and
non-starting of the pump after long periods of standstill, it is
recommended for a newly-installed or converted heating system
that the system be drained, flushed through well and then refilled
again after heating up for the first time. The system must comply
with the latest state of technology. (Positioning of expansion
vessel or initial safety feed.)

4.2 Antifreeze (where necessary)

Important: Rinse the piping especially thoroughly before filling
with the antifreeze mixture. Follow the instructions of the supplier
of the antifreeze concerning mixing, filling, and the selection of
materials in the line and device network (observe the corrosion
protection!) The water / glycol mixture may contain up to 50%
glycol. Correct the flow data for the pumps accordingly if there
is more than 10% glycol.

4.3 Installation

Only install after all of the welding and soldering has been done
on the system. Prevent water from dripping on the pump motor,
especially the electronics. Install the pump housing in the system
without current.

Cable screw connector left
Direction of flow
housing indicates
the direction of flow.
The terminal box must not
face upwards, since water
could then easily penetrate.
The terminal box can be
turned through 90° before
installing the pump. For
this purpose the 4 housing
screws can be released and
the motor head turned to
the permitted terminal box
position. Do not displace or
damage the seal between
motor and pump housing.
After inserting the screws
tighten crosswise alter-
nately. The arrow on the
pump housing indicates the
direction of flow. The shaft
must always be horizontal,
never vertical.
