5 Assembly / Installation
5.1 Installation
– The pump must be installed in a dry, well-venti-
lated and frost-free place.
– Before installing the pump, remove the two hal-
ves of the heat insulation shell.
– Installation should only take place once all wel-
ding and soldering work has been completed
and the pipe network has been rinsed. Dirt can
have an adverse effect on the functioning of the
pump.
– The pump must be installed in an easily acces-
sible place to facilitate inspection and replace-
ment.
– It is recommend that shut-off devices be instal-
led in front of and behind the pump. This will save
having to drain and refill the entire system if the
pump needs to be replaced.
Assemble the pump such that water cannot drip
onto the pump motor or terminal box.
– When assembling pumps with combination
flange PN6/10, always follow the guidelines be-
low (Fig. 3):
1. Do not assemble one combination flange to
another.

Risk of leaking!
– Securing elements such as
split washers are not relia-
ble.
– Faulty assembly can cause
the screw nut to become
hooked into the long slot.
This in turn can lead to in-
sufficient tightening of the
screws and impede the ope-
ration of the flange connec-
tion.
perty class of 4.6 for all flange connections.
When using screws made of any material ot-
her than 4.6 (e.g. 5.6 or greater), observe the
screw tightening torque given for 4.6 during
assembly.
Admissible screw tightening torques:
for M 12 f 40 Nm,
for M 16 f 95 Nm,
Risk of leaking!
Should screws of a property
class of greater than 4.6 be
tightened at a tightening torque
other than that indicated, the
greater tension could lead to
splitting of the edges of the
long slot. This in turn will re-
duce the tightness of the
screws causing the flange con-
nection to produce leaks.
