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. The use of a
diaphragm vessel on the delivery pipe is recommended.
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.
