Installation
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.
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
and indicates an ERROR message. EASY PRESS
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

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.

start-up pressure (Pm). If, for
5 m
example, EASY PRESS
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
the pump and indicate a 'dry
running' error message.

Cable bushing
(dripping), EASY PRESS
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
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
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.

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
will stop
