Technical specications
Operating conditions
A. Compatible/non compa-
tible uids
EASY-SMALL is suitable for use
with clean water and chemical-
ly non-aggressive liquids. If the
fluid contains impurities a filter
should be fitted upstream
B. Environmental conditions
EASY-SMALL 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-SMALL can only be used
with single-phase pumps.

Safety regulations
Before installing or using
EASY-SMALL, read this manual
carefully and thoroughly.
The pump should be installed
and serviced by qualified pe -
sonnel, responsible for making
the hydraulic and electrical
connections in compliance with
the relevant regulations.
PEDROLLO 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 unqua-
lified 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 fitted with proper protection
device (fuse or magneto-
thermal relay) upstream of
EASY-SMALL
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.
EASY-SMALL is put OUT OF
SERVICE.
EASY-SMALL is a device that
starts and stops the pump to
which it is fitted 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 flow rate
required is zero or less than the
“shut-off flow rate (Qa). EASY-
SMALL’s electronics protect
the pump against unsuitable
operating conditions such as
dry running or repeated start-
ups due to leaks.
EASY-SMALL features two
threaded 1” BSP female
outlets, positioned at 90° the
one to the other, to be able to
directly fit an expansion tank
to the device; this is useful in
case of any system drips, to
prevent the continual restart of
EASY-SMALL.
