5 DESCRIPTION OF THE CIRCULATOR
The circulator is of wet rotor type with an integrated electronic frequency converter (INVERTER).
The circulator combines an advanced hydraulic system, a high efficiency motor, intuitive control electronics and operating
software that allow it to adapt perfectly to the various operating conditions and the actual system requirements. The
motor including the electronic regulation module is fitted on the pump casing with four screws. Depending on the set
operating mode, the differential pressure is based on different criteria.
In all regulation modes, the circulator adapts to the different system loads.
5.1 SAFETY STATE OF THE CIRCULATOR
The circulator is in the safety state when it is isolated from the energy supply source, the residual energies have been
dissipated and no conditions that could compromise the general safety state are found.
Proceed as follows to set the circulator in the safety state:
1) Stop the circulator by turning the main electrical switch (installed by the Client) to Pos. “0” or by disconnecting the
plug from the electrical socket
2) Close the system valves downstream and upstream of the circulator
3) Wait for the circulator to cool
5.2 INTENDED USE
Application Civil and/or industrial heating systems
Place of use
The circulator must be placed indoors, in a sufficiently lit and ventilated place that is
protected from bad weather, which conforms to the laws in force in the country of use in
terms of safety
Intended use
Circulation of water/liquid of the hot water heating, air conditioning and solar thermal
renewable energy systems for residential and commercial buildings, such as:
• Residential buildings and condominiums
• Public buildings
• Hotels and restaurants/professional kitchens
• Schools and gyms/sports facilities
• Offices, craft and industrial buildings
Pumped liquids
Clean, non-aggressive and non-explosive liquids, which do not contain solid particles,
fibres or mineral oils. In the heating systems: water according to VDI 2035, Mixtures of
water and glycol with percentages that are not higher than 30%
TAB. 6 (Intended use)
WARNING
THE APPLIANCE CAN BE USED BY CHILDREN UNDER 8 YEARS OF AGE AND BY PEOPLE WITH REDUCED PHYSICAL, SENSORY
OR MENTAL ABILITIES, OR WITHOUT EXPERIENCE OR THE NECESSARY KNOWLEDGE, PROVIDED THAT THEYARE SUPERVISED
OR AFTER THEY HAVE BEEN GIVEN INSTRUCTIONS RELATING TO THE SAFE USE OF THE APPLIANCE AND THEY HAVE
UNDERSTOOD THE RISKS INVOLVED. CHILDREN MUST NOT PLAY WITH THE APPLIANCE.

GUARDS AND DEVICES.
4) IT IS FORBIDDEN TO NEUTRALISE, TAMPER WITH, MANIPULATE OR BYPASS THE GUARDS AND PROTECTIVE DEVICES
INSTALLED IN THE CIRCULATOR.
5) IT IS FORBIDDEN TO USE THE CIRCULATOR FOR PUMPING LIQUIDS OTHER THAN THOSE THAT ARE SUITABLE FOR PUMPING
(SEE PAR. 5.8).
6) IT IS FORBIDDEN TO USE THE CIRCULATOR IN DRY MODE.
7) IT IS FORBIDDEN TO HANDLE THE CIRCULATOR BY GRASPING THE HEAT SINK AS THIS CAN DAMAGE THE ELECTRONIC
BOARD.
WARNING
1) IT IS FORBIDDEN TO MAKE ANY MODIFICATION TO THE CIRCULATOR, WHICH INVALIDATES THE WARRANTY.
2) IT IS FORBIDDEN TO INSTALL EQUIPMENT, ACCESSORIES AND/OR NON-ORIGINAL SPARE PARTS ON THE CIRCULATOR.
