Clean, free from solids and mineral oils, not viscous, chemically neutral, close to the properties of water (max. glycol contents 30%).

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.

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.

evoytred OK OK evoytred OK NO NO

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^ . 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.

EVGTRED EVGO PEALONG IPx5

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.

Diagram showing various smart lockers with warning symbols and labels, including 'EVOYTRAD' and 'DELLINO' variants.

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

Water at high temperature. High temperature.

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 high 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.

9. ELECTRICAL CONNECTIONS

The electrical connections must be made by expert, qualified personnel.

ATTENTION! ALWAYS RESPECT THE LOCAL SAFETY REGULATIONS.

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).

THE SYSTEM MUST BE CORRECTLY AND SAFELY EARTHED!

It is advised to install a correctly dimensioned differential switch to protect the system, type: class A with adjustable leakage current, selective.

The automatic differential switch must be marked with the following symbols:

– The circulator does not require any external motor protection.
- Ensure that the supply voltage and frequency are the same as the values indicated on the electrical data plate of the circulator.

9.1 Power supply connection

1 Prepare the wiring up to the terminal box. Slacken the two fixing screws. 2 Remove the cover Connect the cables to the terminal block cables.

Tabella 4: Wiring Evosta2, EVOSTA2d

10. START

All the starting operations must be performed with the cover of the EVOSTA2, EVOSTA2d control panel closed.

Start the system only when all the electrical and hydraulic connections have been completed.

Avoid running the circulator when there is no water in the system.

As well as being at a high temperature and pressure, the fluid in the system may also be in the form of steam. DANGER OF SCALDING!

It is dangerous to touch the circulator. DANGER OF SCALDING!

Once all the electrical and hydraulic connections have been made, fill the system with water and if necessary with glycol (for the maximum glycol percentage see par. 4) and feed the system.

Once the system has been started it is possible to modify the operating modes to adapt better to the plant requirements.

The regulating mode may be set through the EVOSTA2, EVOSTA2d control panel.

11.1.1 Regulation with Proportional Differential Pressure

EVOSTA 2d EVOSTA 2

In this regulating mode the differential pressure is reduced or increased as the demand for water decreases or increases.

The Hs set point may be set from the display.

Regulation indicated for:

• Heating and conditioning plants with high load losses
• Plants with secondary differential pressure regulator
  – Primary circuits with high load losses
  – Domestic water recirculating systems with thermostatic valves on the rising columns

11.1.2 Regulation with Constant Differential Pressure

EVOSTA2d EVOSTA2

In this regulating mode the differential pressure is kept constant, irrespective of the demand for water, The Hs set point may be set from the display.

Regulation indicated for:

• Heating and conditioning plants with low load losses
• Single-pipe systems with thermostatic valves
• Plants with natural circulation
  – Primary circuits with low load losses
  – Domestic water recirculating systems with thermostatic valves on the rising columns
