When the unit is connected to the electrical network, the green LED “Power On” lights up and the yellow LED “Pump On”
indicates that the pump is in operation. The pump continues to operate for up to 5 seconds enabling the system to fill the
pipes and to reach the required pressure. If this is insufficient, the red LED “Failure” lights up. In this event, keep the “Restart”
button pressed and wait with a tap open until the red LED “Failure” light is off. Once the button is released and the tap is
closed, the unit stops the pump is at it’s maximum pressure.
STARTING
FUNCTIONING
If the column of water between the pump and
the highest tap exceeds 15m, the unit cannot be
installed directly on the pump. The
PRESSCONTROL has to be raised until the
column of water between the unit and the
highest tap does not exceed 15m
It is advisable to connect the
unit outlet to the system by
means of a flexible hose
Safety valve preventing
water emission in case of
diaphragm breaks
DO NOT TOUCH!
It is imperative to
install the unit with
the arrows in the
upward position
The unit can be installed
directly on the pump or
between the pump and the
first tap
The unit is equipped with a
non-return valve to prevent the
pipeline from losing pressure
No taps can be installed between
the pump and the unit
The unit is pre-set by the
manufacturer at the restarting
pressure of 1.5bar (22psi). The
pressure produced by the pump
must be 0.8bar (12psi) higher than
the preset pressure
INSTRUCTIONS FOR CORRECT UNIT INSTALLATION
When starting operation is achieved, the unit is programmed to perform all the pump control operations automatically. When
particular operational breakdowns occur, such as water failure, obstruction of the suction pipe etc, the unit recognises the
breakdown and the red LED “Failure” lights up. At the same time a stop signal is sent to the pump to prevent damages caused
by it’s working in the absence of water. Rectification of the failures that have caused the blockage, allows the system to be
restarted manually by pressing the “Restart” button.
