Preliminary checks
Take the EASY PRESS
®
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 PRESS
®
’s inlets
and outlets are clean and free
of any packaging materials,
- that the check valve moves
smoothly.
Hydraulic connections
Orientation
EASY PRESS
®
can be installed
at any angle depending on the
flow direction, as indicated in
the diagrams.
Position
EASY PRESS
®
can either be fit-
ted directly to the pump outlet
or anywhere along the delivery
line. Never install taps between
the pump and EASY PRESS
®
.
Do not install a non-return
valve between EASY PRESS
®
and the taps, meanwhile it is
possible, although not neces-
sary, to install a non-return
valve on the suction piping of
the pump.
Installation
Red =

Attention
The pressure applied
by the water column above
EASY PRESS
®
must not
exceed that of the pump
start-up pressure (Pm). If, for
example, EASY PRESS
®
is in-
stalled at a height 20 metres
below that of the highest tap
in the system, the pressure
detected by EASY PRESS
®
will be approximately 2 bar.
A model with Pm = 2.2 bar
should, therefore, be installed
in order to guarantee that the
pump is started when a tap is
turned on.
Attention
The maximum pressure
produced by the pump must
be at least 1-1.5 bar higher
than the start-up pressu-
re (Pm). If the pressure
produced by the pump is too
low, EASY PRESS
®
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 PRESS
®
is fitted with a
check valve: do not use the
EASY PRESS
®
’s outlet to fill the
pump for priming.
Switching the pump on
The red (Power) LED lights up;
EASY PRESS
®
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 PRESS
®
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 longer in order
to complete the priming
procedure.
Press the START/STOP
button
to restart the
pump and
complete the
priming procedure.

Cable bushing
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.
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.
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 PRESS
®
stops the pump
and indicates an ERROR message. EASY PRESS
®
AUTOMATICALLY
tries to resume NORMAL SERVICE at intervals of increasing time
(15, 30, 60 minutes and successively once every hour). If EASY
PRESS
®
detects any pressure and/or flow, 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 1- 2 litres/min.
This may cause damage to the pump. In event of small leaks
(dripping), EASY PRESS
®
’s water accumulator guarantees that the
pump starts/stops at time intervals of over 2 minutes (less than 30
starts/hour) and that FREQUENT START-UP errors do not occur. In
the event of a major leak or extended use at excessively low flow
rates (less than 1 - 2 litres/min), the pump may be started/stopped
as often as once every few seconds, putting the pump at risk of
damage. In this case, after about 30 minutes, EASY PRESS
®
stops
the pump for the following 30 minutes (in order to let it cool down)
and indicates an ERROR message. If the time interval between the
starts-stops is more than 10 seconds (and therefore poses less of
a risk to the pump), EASY PRESS
®
will allow the pump to be used
for more than 30 minutes. Once that enough time has passed to
allow the pump to cool down it is restarted AUTOMATICALLY. The
pump may be restarted MANUALLY any time.
