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.

Security measures must be taken to see that persons
do not inadvertently come into contact with the hot
surface areas of the pump.
Install a stop slide valve before and after the pump.
This will save the whole system having to be drained and refilled
in the event of any possible replacement of the pump.
4.6 Minimum pressure
At 75° the minimum pressure at the pump intake, when the pump
is running, is to ensure lubrication of the sleeve bearings:
LX 321, LX 322, LX 323 (single pumps)
LXD 321, LXD 322, LXD 323 (twin pumps)
HX 301, HX 302 (single pumps)
HXD 301, HXD 302 (twin pumps)
The values apply up to 500 m (1640 ft) above sea level.
Additional pressure for greater heights:
0.01 bar per 100 m (328 ft) additional altitude.
