4.4 Installation position

As supplied
Cable screw connector left
The arrow on the pump
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 alternately.
The arrow on the pump
housing indicates
the direction of flow.
The shaft must always be
horizontal, never vertical.

4.5 Return valve

If a return valve has been
fitted, the pump must be
set up (see 5.4.2) so that the
minimum delivery pressure
of the pump can exceed
the closing pressure of
the valve at any time.
