Electrical connections
The electrical connections
should be made as
indicated in the diagram
which can also be found on
the inside of the circuit cover.
Attention! The cable bushings and
circuit board cover must be properly
assembled and secured in order to
guarantee IP 65 grade protection of the
electrical components.
Preliminary checks
Take the EASY-SMALL out of
the packaging and check the
following:
- check for damage,
- check the RATINGS corre-
spond with those required,
- that the cable bushings and
screws are in place,
- that EASY-SMALL’s inlets and
outlets are clean and free of
any packaging materials,
- that the check valve moves
smoothly.
Hydraulic connections
Orientation
EASY-SMALL can be installed
at any angle depending on the
flow direction as indicated in
the diagrams.
Position
EASY-SMALL can either be fit
ted directly to the pump outlet
or anywhere along the delivery
line. Never install taps between
the pump and EASY-SMALL.
Do not install a non-return
valve between EASY-SMALL
and the taps, meanwhile it is
possible, although not neces-
sary, to install a non-return
valve on the suction piping of
the pump.
Expansion tank (optional):
The expansion tank features
1” BSP M thread and must
be inflated in the absence
of system pressure, to about
90% of restart pressure (e.g.
if the restart pressure is 1.5
bar, the inflation pressure will
be 1.3 bar.
Installation
Attention
The pressure
applied by the water column
above EASY-SMALL must
not exceed that of the pump
start-up pressure (Pm).
Attention
The maximum
pressure produced
by the pump must be at least
1-1.5 bar (15 psi) higher than
the start-up pressure (Pm).
If the pressure produced by
the pump is too low, EASY-
SMALL will stop the pump
and indicate a ‘dry running’
error message.
First start-up
Priming the pump
For instructions on how to
prime (fill) the pump see the
pump manual.
Attention
EASY-SMALL is fitted with a
check valve: do not use the
EASY-SMALL’s outlet to fill the
pump for priming.
Switching the pump on
The red (Power) LED lights up;
EASY-SMALL instantly detects
that there is no
pressure within
the system and
starts the pump
(the green ‘Status’
LED lights up).
If, within 15
seconds of starting
up, EASY-SMALL
does
not detect the
correct priming of
the pump, it stops the pump
and indicates a ‘dry running’
error message.
Attention
When the pump is started for
the first time it may
have to be run for lon-
ger in order to complete
the priming procedure.
Press the START/STOP
button
to restart the
pump and
complete the
priming procedure.
NOTE 1 - DRY RUNNING = there is no flow and the pressure is
lower than that of the pump start-up pressure (Pm). It occurs when
there is no water. After 15 seconds EASY-SMALL stops the pump
and indicates an ERROR message. EASY-SMALL AUTOMATICAL-
LY tries to resume NORMAL SERVICE at intervals of increasing
time (15, 30, 60 minutes and successively once every hour). If
EASY-SMALL detects any pressure and/or flo , NORMAL SERVICE
is resumed, otherwise, the pump is stopped again until the next
attempt is made. A MANUAL attempt to resume NORMAL SERVICE
can be made at any time.
NOTE 2 - FREQUENT START-UP = the repeated stopping and
starting of the pump at intervals of less than 2 minutes from each
other. This occurs when the flow rate is less than 2 litres/min (0,5
gpm). This may cause damage to the pump. In the event of leaks
or extended use at excessively low flow rates (less than 2 litres
min (0,5 gpm)), the pump may be started/stopped as often as once
every few seconds, putting the pump at risk of damage.
In this case, after an interval of time that depends on frequency of
start/stop, EASY-SMALL stops the pump for the following 30 minu-
tes, in order to let it cool down, and indicates an ERROR message.
After 30 minutes, the pump is restarted AUTOMATICALLY.
The pump may be restarted MANUALLY any time.

Operation
EASY-SMALL is switched off.
Press briey or hold down
= nothing happens
Power is restored = EASY-SMALL
resumes NORMAL SERVICE and starts
the pump (if necessary).
No power supply
The system is pressurised. All taps are turned
off. There is no demand for water. EASY-SMALL
detects an assembly pressure higher than that of
the start-up pressure (Pm) and no flo .
Press briey = the pump is started
manually and runs for a few seconds
before stopping again.
Hold down = lthe pump is put OUT
OF SERVICE. For instructions on how
to reactivate the pump, see point 3.
A tap is turned on = as soon as the pressure
falls below the start-up pressure (Pm), the pump
is started.
NORMAL SERVICE: the pump is inactive.
The pump has been stopped manually. The pump
will remain inactive until a new
command is given.
Press briey
= nothing happens.
Hold down
= the pump resumes NORMAL SERVICE. See
points 2a - 2b.
OUT OF SERVICE
(See NOTE 1)
EASY-SMALL has detected that the pump is dry
running and has therefore stopped it TEMPORA-
RILY.
Press briey = the pump is started
and manually and resumes NORMAL
SERVICE. See points 2a - 2b.
Hold down
= the pump is put OUT OF SERVICE.
For instructions on how to reactivate the pump,
see point 3.
ERROR: stopped temporarily due to DRY RUNNING
The assembly requires water. One or more taps
are turned on. EASY-SMALL detects a flow; the
assembly pressure is normally higher than the
START-UP pressure, but it may also be lower.
Press briey or hold down
= the pump is stopped and put OUT
OF SERVICE.
For instructions on how to reactivate
the pump, see point 3.
The taps are turned off = Sif there
is no flow for a few seconds the pump is stopped.
NORMAL SERVICE: the pump is running
(see NOTE 2)
EASY-SMALL has detected that the pump
starting-up too often and has therefore stopped it
TEMPORARILY.
Press briey = the pump is started
and manually and resumes NORMAL
SERVICE. See points 2a - 2b.
Hold down = the pump will not
restart and goes OUT OF ORDER. the
pump is put OUT OF SERVICE. For instructions on
how to reactivate the pump, see point 3.
ERROR: temporary shut down due to FREQUENT
START UP
= Off = On = Flashing = Flashing

the pump (if necessary).
NO POWER SUPPLY
The system is pressurised. All taps are
turned off. There is no demand for water.
EASY-SMALL detects an assembly pressure
higher than that of the start-up pressure
(Pm) and no o.
Press briey = the pump is started
manually and runs for a few seconds
before stopping again.
Hold down = the pump is put OUT
OF SERVICE. For instructions on how
to reactivate the pump, see point 3.
A tap is turned on = as soon as the pres-
sure falls below the start-up pressure (Pm),
the pump is started.
NORMAL SERVICE: the pump is inactive
The pump has been stopped manually. The pump
will remain inactive until a new command is given.
Press briey = nothing happens.
Hold down = the pump resumes
NORMAL SERVICE.
See points 2a - 2b.
OUT OF SERVICE
(See NOTE 1)
EASY-SMALL has detected that the pump is dry
running and has therefore stopped it TEMPO-
RARILY.
Press briey = the pump is started
and manually and resumes NORMAL
SERVICE. See points 2a - 2b.
Hold down = the pump is put OUT
OF SERVICE. For instructions on how
to reactivate the pump, see point 3.
ERROR: stopped temporarily due to DRY RUNNING
The assembly requires water. One or more
taps are turned on. EASY-SMALL detects
a ow; the assembly pressure is normally
higher than the START-UP pressure, but it
may also be lower.
Press briey or hold down = the pump
is stopped and put OUT OF SERVICE. For
instructions on how to reactivate the
pump, see point 3.
The taps are turned off = If there
is no ow for a few seconds the pump
is stopped.
NORMAL SERVICE: the pump is runningt
(see NOTE 2)
EASY-SMALL has detected that the pump
starting-up too often and has therefore stopped
it TEMPORARILY
Press briey = the pump is started
and manually and resumes NORMAL
SERVICE. See points 2a - 2b.

Size (mm)
The system has just ceased to require water.
All taps are closed. The pump is still in
operation. The system is pressurized. EASY-
SMALL detects a system pressure higher than
the start-up pressure (Pm) and no ow
.
Press briey or hold down = the
pump is stopped and put in STAND-BY
To reset see point 3.
If the absence of ow lasts for a few
seconds the pump is stopped.
NORMAL SERVICE: pump during shutdown
