5 DESCRIPTION OF THE CIRCULATOR
The circulator has a wet rotor 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 needs of the plant.
The motor including the electronic adjustment module is mounted on the pump body by four screws. Depending on the
set operating mode, the differential pressure follows different criteria.
In all regulation modes, the circulator adapts to the different loads of the system.
5.1 SAFETY STATE OF THE CIRCULATOR
The circulator is in “safety state” when it is isolated from the power supply sources, the residual energy has been
dissipated and no conditions that could compromise the general state of safety are detected.
To place the circulator in “safety state” proceed as follows:
1)Stopthecirculator bringingthemainelectricswitch(bytheCustomer)intoPos. “0” orbydisconnectingtheplugfrom
the electrical socket.
2)Close the valves of the plant downstream and upstream of the circulator.
3)Wait for the circulator to cool down.
5.2 INTENDED USE
Field of use Civil and/or industrial heating systems
Place of use The circulator must be placed inside, in a sufficiently illuminated and ventilated place protected from the weather, suitable for the laws in force in the country of use regarding
safety
Intended use
Water/liquid circulation of water heating systems by hot water, air conditioning and
renewable solar thermal energy systems for residential and commercial buildings such as,
for example:
• 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, not containing solid particles, fibers or mineral oils. In heating systems: water according to VDI 2035, water and glycol mixtures
with percentages not exceeding 30%
