USER'S MANUAL
ELECTRONIC PUMP CONTROLLER
PRESFLO is a device that
®
starts and stops the pump to
which it is 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 ow

Operating conditions
A. Compatible/non compat-
ible uids
PRESFLO is suitable for use
®
with clean water and chemical-
ly non-aggressive liquids. If the
uid contains impurities, a lter
should be 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
rate required is zero or less
than the "shut-off ow rate"
(Qa). The running pressure
(Pm) is mechanically adjustable
via knob.
PRESFLO 's electronics protect
®
the pump against unsuitable
operating conditions such as
dry running or repeated start-
ups due to leaks.
Before installing,
the product, check that
the RATINGS correspond
with those required.
