4.3 Position for assembling
The delivery position
is position A
The terminal box must not
point downwards (M, N, O, P),
as otherwise water may
penetrate easily.
Before installing the pump,
the terminal box can be
turned by 90° in each case.
To do this, undo the casing’s
4 screws and turn the motor
head to the required terminal
box position.
Do not shift or damage the
seal between the motor and
pump casing. After inserting
the screws, tighten them up
diagonally.
4.4 Installation
Installation only after
completion of all welding
and soldering work.
Be sure to avoid any water
dripping onto the pump
motor and especially
the terminal box.
The shaft must always
be
horizontal,
never vertical.
Install the pump casing
stressfree in the system.
4.5 Direction of flow
The arrow on the pump
casing indicates the direction
of flow.
4.6 Return valve
If a return valve has been
installed, the pump has to be
set up (see point 6.4)
so that the pump’s minimum
delivery pressure can exceed
the valve’s closing pressure
at any time.
Security measures must be taken to see that persons
do not inadvertently come into contact with the hot
surface areas of the pump.
