DESCRIPTION
AUTOMATIC REGULATOR FOR PUMPS
Smart Press is an automatic electronic device, designed to
regulate pump operation, without using autoclave tanks.
Smart Press performs the following operations:
1) Controls pump operation, automatically and without
interruption, with constant pressure and delivery during
supply from one or more distribution points.
The pump starts when the pressure of the system is less than
the fixed pressure (std 1.5 bar). Il stops when
Smart Press
no longer detects an appreciable outlet flow (see point 2).
2)
Keeps the pump operating for a brief period
(approximately 5 seconds) after supply has stopped at the tap
closing.
3)
If there is no water at the suction point, it blocks the
pump,without using level probes or float switches. Or it
releases automatically when a pressure above the one
required to start the motor-driven pump is injected in the
delivery line.
One version of system is identified as Smart Press WG
(where WG is for Water Guardian).
In case of block due to lack of water, this system effects
some tries of automatic random, as equal as pressing the
pushbutton of manual reset, every 30 Min.
4)
It is supplied with a flow sensor, manufactured with a
geometry which reduces the loading losses even with very
high flows.
5)
Lights indicate the various operation phases:
green LED on : present power supply
yellow LED on : pump working
red LED on : blocked due to lack of water at supply point.

INSTALLATION
Warning!
During installation, as well as during any maintenance
operations, the electrical power supply must be disconnected
by removing the cord or using the switch. The electrical
connection must be made by a trained individual following
the safety regulations in force.
a)
Normally the Smart Press is mounted directly on the
delivery point of a surface pump: the device is connected with
a l" male, however it can be mounted at any point on the
delivery piping (even on a submerged pump) in a vertical or
horizontal position. Avoid applying check valves
to the
downstream , on recommend the application to the
upstream.
b)
The Smart Press delivery should be connected to the
water supply (1 ¼" female) on recommend to use a flexible
hose to prevent damage from tightening and /or vibration.
c) The standard model of Smart Press works correctly if
the highest point of use doesn't overcome 15 meters highs.
Change this value using the setting screw (dowel) on the front
side of the
Smart Press . Turn the screw clockwise to
increase the ignition value. Turn counterclockwise to reduce
the ignition value.
d)
Make sure that the pump primes perfectly by filling the
body of the pump and suction hose with water. If the pump is
going to be used with supply from a low level (well) always
install a foot valve.
e)
Perform electric connection observing the serigraphy on
the electronic card located in front of the clamps.
TROUBLESHOOTING
THE PUMP JAMS: (red LED on) reset the priming and
eliminate the cause of the failure to prime (suction leak,
malfunctioning foot valve, tank without water, etc.). Then
press the manual reset button being careful not to run the
pump with no water to prevent damaging the seal and
hydraulic part.
THE PUMP GOES ON AND OFF CONTINUOUSLY:
find the leak in the delivery system and eliminate it.
THE EQUIPMENT IS COMPLETELY OFF (NO LlGHT
ON) AND WILL NOT START AGAIN:
Check the power supply . If the board has been removed for
replacement or for easier wiring, check if the flux sensor
located in the rear part of the board, is properly located in its
housing in the main body, while carefully avoiding to crush
the feet which cause the board to stop completely.
