2.3 Particular warnings
Always switch off the mains power supply before working on the electrical or
mechanical part of the system. Wait for the warning lights on the control panel to go
out before opening the appliance. The capacitor of the direct current intermediate
circuit remains charged with dangerously high voltage even after the mains power has
been turned off.
Only firmly cabled mains connections are admissible. The appliance must be earthed
(IEC 536 class 1, NEC and other applicable standards).
Mains terminals and motor terminals may still have dangerous voltage when the motor
is stopped.
If the power cable is damaged, it must be replaced by the technical assistance service
or by qualified personnel, so as to avoid any risk.

5. APPLICATIONS
EVOSTA2, EVOSTA2d series circulators allow integrated adjustment of the differential pressure which
enables the circulator performance to be adapted to the actual requirements of the system. This determines
considerable energy saving, a greater possibility of control of the system, and reduced noise.
EVOSTA2, EVOSTA2d circulators are designed for the circulation of:
–water in heating and conditioning systems.
–water in industrial water circuits.
–domestic water only for the versions with stainless steel pump body.
EVOSTA2, EVOSTA2d circulators are self-protected against:
–Overloads
–Lack of phase
–Excess temperature
–Over-voltage and under-voltage

7. MANAGEMENT
7.1 Storage
All the circulators must be stored in a dry covered place, with possibly constant air humidity, free from vibrations
and dust. They are supplied in their original pack in which they must remain until the time of installation. If this
is not the case, accurately close the suction and delivery mouth.
7.2 Transport
Avoid subjecting the products to needless impacts and collisions. To lift and transport the circulator use lifting
devices with the aid of the pallet supplied with it (if contemplated).
7.3 Weight
The adhesive plate on the packaging indicates the total weight of the circulator.
8. INSTALLATION
Always switch off the mains power supply before working on the electrical or
mechanical part of the system. Wait for the warning lights on the control panel to go
out before opening the appliance. The capacitor of the direct current intermediate
circuit remains charged with dangerously high voltage even after the mains power has
been turned off.
Only firmly cabled mains connections are admissible. The appliance must be earthed
(
IEC 536 class 1, NEC and other applicable standards
)
.
Ensure that the voltage and frequency on the data plate of the EVOSTA2, EVOSTA2d
circulator are the same as those of the power mains.
8.1 Mechanical installation
Figure 2: Mounting EVOSTA2, EVOSTA2d
The arrows on the pump housing indicate the flow direction through the pump. See fig. 1, pos. A.
1. Fit the two gaskets when you mount the pump in the pipe. See fig. 1, pos. B.
2. Install the pump with a horizontal motor shaft. See fig. 1, pos. C.
3. Tighten the fittings.

8.2 User Interface Position
Always install the EVOSTA2, EVOSTA2d circulator with the motor shaft in a horizontal
position.
Install the electronic control device in a vertical position.
Figure 3: Assembly position
The circulator may be installed in heating and conditioning systems on either the delivery pipe or the return
pipe; the arrow marked on the pump body indicates the direction of flow.
Install the circulator as far as possible above the minimum boiler level and as far as possible from bends,
elbows and junction boxes.
To facilitate control and maintenance operations, install an interception valve both on the suction pipe and
on the delivery pipe.
Before installing the circulator, accurately flush the system with only water at 80°C. Then drain the system
completely to eliminate any harmful substance that may have got into circulation.
Avoid mixing additives derived from hydrocarbons and aromatic products with the circulating water. It is
recommended that the addition of antifreeze, where necessary, should not exceed 30%.
In the event of heat insulation use the special kit (if provided) and ensure that the condensate draining
holes in the motor casing are not closed or partly blocked.
In the case of maintenance, always use a set of new gaskets.
Never insulate the electronic control device.

8.2.1 Positioning of the user interface in heating and domestic hot water systems
It is possible to position the user interface with the cable facing to the left, to the right, or downwards.
Figure 4: Positions of the user interface
8.2.2 Positioning of the user interface in conditioning and cold water systems
The user interface can be positioned only with the cable facing downwards.
Figure 5: Positions of the user interface
8.3 Rotation of the user interface
If the circulator is installed on pipes in a horizontal position, it will be necessary to rotate the interface with the
respective electronic device through 90 degrees in order to maintain the grade of IP protection and to allow
the user a more convenient interaction with the graphic interface.

ENGLISH

Before rotating the circulator, ensure that it has been completely drained.
To rotate the EVOSTA2, EVOSTA2d circulator, proceed as follows:
1. Remove the 4 fixing screws of the circulator head.
2. Rotate the motor casing with the electronic control device through 90 degrees clockwise or
counterclockwise, as necessary.
3. Reassemble and tighten the 4 screws that fix the circulator head.
The electronic control device must always remain in vertical position!

ATTENTION
System under pressure
- Before dismantling the pump, empty the system or close the interception valves on
both sides of the pump. The pumped liquid may be at a very high temperature and
hi

h pressure.
8.4 Non-return valve
If the system is equipped with a non-return valve, ensure that the minimum pressure of the circulator is always
higher than the valve closing pressure.
