AIR VENT VALVE ACTIVATION
When starting the pump, or when emptying the tank, slightly open the small valve, in order to
let the air out and facilitate the priming.
As soon as the pump is operating close the small valve.
ELECTRONIC PRESSURE SENSOR WORKING DIRECTIONS
The electronic pressure sensor is controlled by a 8 MHz microprocessor, which constantly
controls pressure, current and voltage of the pump motor in order to guarantee the best
performances under all operational conditions. The variable speed control (rpm) of the
electric motor is proportional to the flow rate demand and has the advantage of reducing
noise level, current consumption and mechanical wear and tear compared to the previous
mechanical pressure switch.The pump can be connected both to a 12V and 24V power
source and will guarantee the same performances under the same absorbed load. The
electronic pressure sensor has a three-colour LED that gives information to the user
regarding the functional status of the pump.When the LED is green and blinking it means
that the pump is in “stand by” mode at the maximum preset pressure waiting for water
demand (i.e. opening of a tap).When the LED is green and steady, the pump is increasing
the flow in order to reach the pre-set pressure and meet the demand flow rate. When the
LED is yellow and steady, the pump has reached the pre-set pressure and is steadying the
flow rate to maintain a constant pressure on the pipe line. A short flickering of the red LED is
showing that the pump is gradually decreasing the flow in order to reduce the pressure to
the pre-set value. If the blue LED is off it means water lack: the pump will stop if water lack
persist and blue LED will blink; the user must switch the power off and start the pump again.
The pump is protected against short circuits and overloads. If an overload occurs, the
pump instantly stops and a yellow-green LED will blink. The electronic system will try to
reactivate the pump at 30” intervals. If the overload reach a dangerous level for the pump,
red LED will become steady. The user must then switch the power off and start the pump
again.

AMBIENT CONDITIONS
TEMPERATURE: min.-10°C 14°F-max.60°C 140°F RELATIVE HUMIDITY: max. 90 %
WARNING: the above indicated temperature ranges are applicable to all components
of the pump and these limits must be respected in order to avoid any possible damage
or malfunctioning.
OPERATING CYCLE
The pump has been designed for discontinuous use. Under conditions of high operating
pressures (eg. with closed or blocked outlet, excessive length of the delivery circuit and/or
excessive pressure due to accessories), it can be subjected to elevated stresses and
overheating and therefore should not be used for prolonged periods under such conditions.
TRANSPORTATION AND HANDLING
Due to limited weight and dimensions the pump does not require the use of any special
handling or lifting equipment. When handling manually, normal personal protective gear
should be worn (safety shoes with toe piece, etc.). The pump is carefully packed prior to
shipment. Upon receiving, the packaging should be inspected for damages and the pump
stored in a dry area.
INSTALLATION
It is recommended that the use of the pump be according to normative safety standards
and also as per the precautions listed below.
PRELIMINARY CHECKS
Check that there has been no damage to the pump during transportation or storage. Both
inlet and outlet ports should be carefully cleaned removing possible dust or residual
packaging material. Verify that the available electrical power supply corresponds to the
specification requirements.
POSITIONING
The pump can be mounted in any position. Fix it utilizing suitable screws corresponding to
the antivibration mounts supplied.

S.p.A.
To ensure the correct directional flow of the fluid as indicated by the arrow on the top plate, it is
necessary to connect the positive pole (+) of the battery supply to the red wire on the motor
end-cap and the negative pole (-) to the black wire. Electrical connections must be made
using adequate terminal blocks and connectors ensuring a tight fitment of the electrical
cables. Bad wiring can cause power losses and/or overheating of the cabling itself.
WARNING: it is the responsibility of the installation technician to ensure a correctly
designed circuit installation fitted according to regulations. Environmental risks must
be taken into account with the installation.
TUBING CONNECTIONS
Ø
Ø
Ø
Ø
Ø
Prior to making any tube/hose connections, check that the inlet ports have no end
caps;
Do not position the pump at a excessive height with respect to the minimum level of
the fluid to be transferred. Damage may occur if this height is exceeded as the pump
may not draw fluid. Make sure that the outlet tube is empty and without chokes;
Avoid choking the inlet or outlet tubes so that efficiency is optimized.
The use of an inlet filter is recommended especially with fluids containing impurities
(ASTM mesh 35). In this case frequent cleaning and maintenance of the filter is
advisable. The standard filter withstands a maximum positive pressure of 0.5 bar.
Utilize tubes and connection pieces that are resistant to the fluid types handled and
avoid any possible environmental dispersion.
ELECTRICAL CONNECTION
The electrical installation of the pump must include a protection fuse which is suitably rated
as indicated on the motor label.
WARRANTY EXPIRES IF NO FUSE IS UTILIZED
Always mount the anti vibration rubber fittings supplied with the pump kit. Their usage
ensures a consistent reduction in noise and vibration levels. Electrical cabling size should
depend on the distance between pump and battery power supply (see Tab.1 EN). The use of
undersized cabling can cause overheating of the electrical wiring and subsequent fire
hazard. There will also be a voltage drop at the motor terminals with a consequent reduction
in efficiency. The flow rate value indicated on the motor label is obtained with internal tube
diameter indicated on Tab.1 EN. Tubes with inferior diameters will cause an increase in
current with potential risk of motor overheating.

TROUBLESHOOTING
CHECK POINTS IF THE PUMP HAS STOPPED OR WILL NOT START
Ø
Ø
Ø
Ø
Ø
Check the effectiveness of the battery power supply (voltage activity);
Check if the fuse has blown;
Check for any foreign matter present in the pump body. To do this, disconnect the
power supply and unscrew the four fixing screws, remove the front cover plate and
inspect the chamber. Replace the cover plate in the same initial position after
inspection;
Avoid running the pump dry for more than a few minutes. Pumps found defective
that have run dry in the absence of fluid are not covered by warranty;
The average life span of the motor commutator brushes is approximately 1500
hours under normal operating conditions. Stoppages are possible due to brush
wear and tear after such a time period.
WHY THE PUMP WILL NOT PRIME ITSELF?
Ø
Ø
Ø
Ø
Ø
Ø
Ø
Ø
The pump is fitted at an excessive height above the fluid level;
The pump has run dry for too long a period;
Long periods of inactivity. In this case it is advisable to add liquid directly into the
chamber before start-up. It is also advisable to add, before running the pump, a drop
of lubricating oil inside the pump only;
Air leak at the suction pipe due to the following reasons, possible cuts in the pipe,
inadequate hose clamps, malfunctioning of the filter due to defective/worn seals or
filter clogged;
Air leak at the front plate cover due to the following reasons, loose fixing screws,
poor effectiveness of the seal;
Faulty electrical cable connections;
Presence of obstructions or restrictions in the suction or delivery pipes or the use of
special devices(eg. automatic spray pistol or aqua-stop);
Presence of liquid loops in the outlet tube.
GOOD PRACTICES ENSURING A WELL FUNCTIONING PUMP
If it is expected that the pump will not be used for a period of at least 30 days, especially in the
case of usage with water, it is advisable to run fresh water through it and to then loosen the
front plate screws. Upon re-use, run the pump briefly (a few seconds) and tighten the screws
again. Check under conditions of maximum operating pressure that the motor current value
is within the motor label specifications.

Ø
Ø
Ø
Check frequently and keep the inlet filter clean;
Check every month the chamber and keep clean from any foreign matter;
Check every month that electrical wiring is in good condition;
Every 1500 hours of pump operation substitute the motor brushes.
Replace the rubber impeller every season or every 500 hours (UP1-J-N-M)
