ELECTRONIC PUMP CONTROLLER
EASY PRESS
®
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
USER’S MANUAL
rate required is zero or less
than the “shut-off ow rate”
(Qa).
EASY PRESS
®
’s electronics
protect the pump against
unsuitable operating conditions
such as dry running or repea-
ted start-ups due to leaks.

Operating conditions
A. Compatible/non compati-
ble uids
EASY PRESS
®
is suitable for use
with clean water and chemically
non-aggressive liquids. If the
uid contains impurities, a lter
should be tted upstream.
B. Environmental conditions
EASY PRESS
®
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.
EASY PRESS
®
can only be
used with single-phase pumps.

Safety regulations
Before installing or using EASY
PRESS
®
, read this manual
carefully and thoroughly.
The pump should be installed
and serviced by qualied per-
sonnel, responsible for making

connections in compliance with
the relevant regulations.
PEDROLLO
®
shall not be
held liable for any damage

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 pro-
perly assembled and secured
( see Electrical Connections ).
- Power supply network must
be tted with proper protec-
tion device (fuse or magneto-
thermal relay) upstream of
EASYPRESS
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 START/STOP.
