2. HANDLING

The unit is supplied suitably packaged to prevent
damage in transit. Before unpacking, check that the
packaging has not been damaged or deformed,
Lift and handle the product with care and with
the right tools.

3. INSTALLATION

These units are designed for indoor use.
3.1. Fitting the Kit
Fit the kit directly at the discharge of the pump, or in
line with the discharge pipes, using the connector
supplied, as shown in Figures 1 and 2. Ensure that
the connectors are watertight (e.g. by using Teflon
tape).
NOTE: The kit must remain in the vertical
position at all times, with the suction mouth
at the bottom and the discharge mouth at
the top. The pressure gauge will be fitted in
the normal reading position
The assembly should be protected from the risk of
flooding and installed in a sheltered place but well
ventilated place.
If the pump to which the Kit is fitted is directly con-
nected to the mains supply, it must be remembered
that the incoming pressure must be added to that
provided by the pump. Total pressure may never
exceed 10 bars.
It can be fitted to any installation that has sufficient
feed flow.
See installation diagrams.

3.2. Discharge pipe assembly

The discharge pipework diameter should be equal to
or larger than that of the pump discharge. It should
not rest against the pressure unit and should be
checked for water- tightness.
We recommend the use of a flexible anti-vibration
hose on the discharge, as direct connection to rigid
pipework could cause damage to the PRESSDRIVE
(Fig. 2).
No check valve needs to be installed.

3.3. Electrical connection

The electrical installation must have a multiple
isolator with minimum 3 mm contact openings,
The protection of the system will be based on
a differential switch (∆fn = 30 mA)
The power cable must correspond at least to the
type H07 RN-F (according to 60245 IEC 57) and
having terminals.
The connection and its dimensioning must be per-
formed by a qualified installer according to the needs
of the facility and following the regulations in force in
each country.
Nominal pump current should be no higher
than 12A and the maximum motor power (P1)
should never exceed 2.5 Kw.
Follow instructions given on fig.3 and 4 for correct
electrical connection.

3.4. Pre-start checks

Ensure the voltage and frequency of the sup-
ply corresponds to the values indicated on the
electrical data label.
Ensure that the pump shaft is rotating freely.
Fill the pump body with water through the self prim-
ing plug opening. If a foot valve has been installed,
also fill the suction pipe.
Check all joints and connections for leaks.
THIS PUMP MUST NEVER BE DRY RUN.

4. STARTING

4.1 Starting up the group

Leave a water spout open to purge the air from the
installation.
Connect the water supply cut-off. The group starts
running for 10". The LINE indicator blinks quickly.
When the time is up:
- If the group supplies water as normal, the motor
continues operating and the LINE indicator is con-
tinuously lit.
- If the pump has not been primed, after 10" an error
is caused due to lack of water. The FAULT indica-
tor blinks and the motor stops. To prime the pump
press the RESET key.
At the end of this operation close the spout and the
group will stop after 10". The LINE indicator blinks
slowly. It is in "standby" mode.

4.2 Lack of water fault and retries

If the PRESSDRIVE detects the pump is working
without water it stops the motor. The FAULT indica-
tor blinks. The PRESSDRIVE will attempt to start up
again after 1', 5', 15' and 1 hour (Fig. 7). If the retries
fail the PRESSDRIVE will enter permanent fault
mode. The FAULT indicator remains lit.
To interrupt the retry cycle or to restart from perma-
nent fault mode, press the RESET key.

4.3 Minimum flow

When the flow supplied by the group is less than 1
l/m, the LINE indicator blinks very quickly. After 10"
the normal motor stop occurs. The group changes to
"standby".

4.4 Adjusting the start-up pressure

The start-up pressure is adjusted using the screw
located on top of the Kit (Fig. 5).
Switch on a tap in the installation and read the pres-
sure shown on the pressure gauge at the moment of
starting.
Turn the adjusting screw in the desired direction. The
start-up pressure should normally be set 0.2 bar (3
psi) over the static pressure of the installation above
the kit.
