ELECTRONIC PUMP CONTROLLER
PRESFLO
®
is a device that
starts and stops the pump to
which it is fi tted, thus replacing
traditional pressure switch /
surge tank systems.
The pump is started when, as
a tap is turned on, the pressure
within the system drops below
the “start-up pressure” (Pm),
and is stopped when the fl ow
USER’S MANUAL
rate required is zero or less
than the “shut-off fl ow rate”
(Qa).
PRESFLO
®
’s electronics protect
the pump against unsuitable
operating conditions such as
dry running or repeated start-
ups due to leaks.
Technical specifi cations
Operating conditions
A. Compatible/non compat-
ible fl uids
PRESFLO
®
is suitable for use
with clean water and chemical-
ly non-aggressive liquids. If the
fl uid contains impurities, a fi lter
should be fi tted upstream.
B. Environmental conditions
PRESFLO
®
should not be used
where there is the risk of an
explosion. The temperature
of the location should range
between 0°C and 40°C, and
the humidity should not exceed
90%.
C. Power supply
Make sure that the variation
in the power supply is never
more or less than 10 % of the
RATING value.
Higher values may cause
damage to the electronic
components.
PRESFLO
®
can only be used
with single-phase pumps.

Safety regulations
Before installing or using
PRESFLO
®
, read this manual
carefully and thoroughly.
The pump should be installed
and serviced by qualifi ed per-
sonnel, responsible for making
the hydraulic and electrical
connections in compliance with
the relevant regulations.
PEDROLLO S.p.A. shall not
be held liable for any damage
relating to, or resulting from, an
improper use of the product,
or for any damage relating to,
or resulting from, servicing or
repairs carried out by unqual-
ifi ed personnel and/or with
non-OEM spare parts.
The warranty, which is valid
for 24 months from the date
of purchase, will no longer be
applicable should the product
suffer damage as a conse-
quence of the use of non-OEM
spare parts, tampering or
improper use.
When starting the installation,
check the following:
- the power supply is switched
off.
- the power lines can withstand
the maximum current.
- the cable bushings and circuit
board cover have been properly
assembled and secured ( see
Electrical Connections ).
- Power supply network must
be fi tted with proper protection
device (fuse or magne-
to-thermal relay) upstream of
PRESFLO
®
When servicing the product,
check the following:
- the system is not pressurised
(turn a tap on)
- the power supply is switched
off.
Emergency Stop
When in use, the pump can
be stopped in the event of an
emergency:
press STOP/RESTART.
PRESFLO
®
is put STAND-BY.
