WARNING - GB -
The manufacturer cannot be held responsible for any kind of damage to people and/or things ensuing from failure to install the necessary
electrical safety devices upstream of the device, or as a result of unprofessional installation.
The installation and servicing of this device must be performed by specially trained personnel with the ability to understand the entire
For all operations required to be carried out with the cover removed, the device must be disconnected from the power supply.
Even though there should not be any reason to remove the card, if you do so, remember that some of its parts remain live for a few minutes
after the unit has been disconnected from the mains.
The manufacturer cannot be held responsible for any kind of damage to people and/or things ensuring from the failure of any internal safety
devices to intervene, with the exception of compensation for the device itself if still under guarantee.
This equipment complies with the directive ROHS 2011/65/EC.
The symbol of the crossed out bin means that to safeguard the environment the equipment cannot be disposed of with other
household waste at the end of its lifecycle.
The equipment and packaging must be disposed of according to the local regulations.
READ THIS HANDBOOK CAREFULLY BEFORE INSTALLING OR STARTING THE DEVICE.

OVERALL SIZE - DIMENSIONS - IDENTIFICATION
DESCRIPTION
The present electronic device, employing inverter-based technology, which controls the pump stopping and starting functions.
Thanks to the particular type of technology used, it can modulate t to alter the speed (rpm)
according to the water delivery rate required from the system.
This way, the value of the pressure reaching the user appliances remains constant and the motor's absorption is always proportional to the
actual system requirements, resulting in notable energy savings over time.

EMC
The product has been tested according to the standards cited in the declaration of CE compliance in one of the typical conditions of use.
Experience has however demonstrated that critical variations to the levels of EMC disturbances may occur by changing the length of the
cables, their position, the type of motor used, etc. When conditions of disturbance towards other devices occur, contact the manufacturer to
evaluate additional solutions to reduce electro-magnetic disturbance.
INSTALLATION
HYDRAULIC CONNECTION:
The inverter must be installed on the pump delivery side, either upright or horizontally and respecting the flow direction shown by the arrow
on the cover. The pump outlet water flows through the device before being distributed to the various appliances connected.
The water that enters the inverter unit must not contain any impurities and/or other substances that could jam up the check valve fitted inside
it. To reduce this risk as much as possible, it is advisable to fit special filters on the intake side of the pump.
When it is not possible to guarantee the perfect cleanliness of the pumped fluid, it is advisable to deactivate operation of the integrated flow
switch.
Is required to install a small expansion tank (1-2 litres) after the inverter, to limit restarts caused by any small leakages which are common in
most systems.
The pre-charge value of the tank must be suitable for the pressure values set. This will also help to keep the operation constant in applications
where water requirements are greater (e.g. for washing machines, toilet flushing systems, etc.).
On no account must a check valve be fitted between the inverter and the motor pump or between the device itself and the user appliances, as
it could cause device malfunctions. When used with a submerged pump, the installation of a check valve before the inverter is allowed,
provided that it is positioned at least 3 metres from the inverter.
It is recommended that you do not install the equipment in shafts or watertight casing where heavy condensation can form.
CAUTION: when the pump stops, the conduits are still pressured so a cock must be opened to bleed the system before any work is
carried out.
ELECTRICAL CONNECTION:
WARNING:
- all wiring up must be carried out by specially trained personnel
- an incorrect motor pump connection could result in damage to the device or the pump motor.
- failure to comply with what is stated in this paragraph may cause serious damage to things and/or
serious injuries to people, and the manufacturer declines all responsibility.
