values refer to the static balancing valve setted at 5.9 (pre-setting) and
at 1.5 for the DPCV
The general equation for calculating pressure drop, knowing flow rate value
is the following
Δp [bar] = (Q [m

Mounting
External casing dismounting-mounting
Before installation the external casing must be removed as indicated in the
image. The external casing is a unique piece placed on the carrying struc-
ture: it is fixed by 2 screws on superior part and 2 screws on inferior part. After
external casing removal and having placed it safely, it is possible to proceed
with the hydraulic unit installation.
Wall mounting
The unit has to be installed indoors in suitable ambient conditions (see tech-
nical specification on page 3).
The installer has to individuate the most suitable wall according to weight and
overall dimensions indicated on page 3.
For fixing unit it is necessary to use no. 4 Ø 8 mm anchors (not included), they
have to be suitable to the chosen wall for installation. The position has to be
compliant with hydraulic connections.
It is suggested to leave a free space of 10cm on left side for an easier access
to the strainer

CAUTION
Before installing the unit, the centralised and apartment systems must
be cleansed and flushed to avoid fouling of the unit with impurities or
debris from the pipe work installation procedures. The presence of
impurities in pipes can be the reason for unsatisfactory working and
can cause possible damages to unit components. Therefore it is very
important to carefully flush pipes before installing.
Connecting the unit to centralized distribution system with
interception manual valves (included) is strongly recommended.
Thanks to this the unit could be quickly and without particular user
unease de-touched from centralized plant in case of special mainte-
nance.
Take care not to damage or break the connection seals. Pipe connec-
tion torque must not exceed 50 Nm.
