7. Installation and connections
All installation and electrical connection work
must be carried out solely by authorised and
qualified personnel, in accordance with applica-
ble regulations!
WARNING! Physical injuries!
The applicable regulations for the prevention of
accidents must be complied with.
7.1 Upon receipt of the product
• Unpack the pump and recycle or dispose of the
packaging in an environmentally responsible
manner.
• Handling (Fig. 4).
7.2 Installation
Two standard types (Fig. 1 and 3)
Pump in suction mode
Pump in inlet mode connected to replenishment
reservoir (item 9) or municipal water mains (item 10).
• The pump must be installed in a dry, well-venti-
lated location free of frost.
CAUTION! Risk of damage to the pump!
The presence of foreign matter or impurities in
the pump housing may affect the
functioning of the product.
• We recommend carrying out all soldering and
brazing work before installing the pump.
• Rinse the circuit completely before installing and
commissioning the pump.
• Remove the blanking caps on the pump housing
before installation.
• The pump must be installed in a place easy to
reach, protected against frost and as close as
possible to the drawing point.
• To ensure access to the motor fan, allow a min-
imum distance of at least 0.3 m from the wall
behind the unit.
• Install the pump on a smooth and horizontal sur-
face.
• Secure the pump through 2 oblong holes on the
pedestal bearing (for Ø M8 fasteners) Fig. 7.
• Bear in mind that the altitude of the installation
site and the water temperature may reduce the
suction capacity of the pump.
WARNING!
The pump must be installed in such a way that
no one can touch the hot surfaces of the product
when it is in operation.
NOTE: As the pump may have been tested in the
factory, there may be some residual water in the
product. We recommend rinsing the pump.
7.3 Hydraulic connections
General connection instructions
• Screw the 2 connections manually (item 11) and
gasket (item 12) (depending on model) Fig. 9.
• Use flexible, braid-reinforced hose piping or rigid
piping.
• The pump must not bear the weight of the pipes
Fig. 5.
• Seal the piping well using appropriate products.
• Install a system of protection against low water
level to prevent dry running of the pump.
• Limit the length of the piping and avoid all fea-
