Installation
Preliminary checks
Take the EASYPRESS 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 EASYPRESS 's inlets and
®
outlets are clean and free of
any packaging materials,
- that the check valve moves
smoothly.
Hydraulic connections
Orientation
EASYPRESS can be installed
®
at any angle depending on the
flow direction, as indicated in
the diagrams.
Position
EASYPRESS can either be fit-
®
ted directly to the pump outlet
or anywhere along the delivery
line. Never install taps between
the pump and EASYPRESS
Do not install a non-return
valve between EASYPRESS
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 EASYPRESS
and indicates an ERROR message. EASYPRESS
tries to resume NORMAL SERVICE at intervals of increasing time
(15, 30, 60 minutes and successively once every hour/optional 24
hours). If EASYPRESS 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 may cause damage to the pump. In the event of leaks
or extended use at excessively low flow rates [less than 2 litres

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

example, EASYPRESS
stalled at a height 20 metres
below that of the highest tap
in the system, the pressure
detected by EASYPRESS
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, EASYPRESS
the pump and indicate a 'dry
running' error message.

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, EASYPRESS

After 30 minutes, the pump is restarted AUTOMATICALLY.
The pump may be restarted MANUALLY any time.
NOTE 3 - BLOCKAGE DUE TO PROLONGED IDLENESS = If the
pump remains idle for extended periods, it may result in jamming
of the mechanical seal or impellers. To avoid this problem,
EASYPRESS performs a restart, lasting 7 seconds every 24 hours.
