  • Page 6: Product Description

    Figure 1: Pumped liquids, warnings and operating conditions The circulators in the EVOSTA2 and EVOSTA3 series represent a complete range of circulators. These installation and operating instructions describe EVOSTA2 and EVOSTA3 models. The type of model is indicated on the pack and on the identification plate.

  • Page 7: Applications

    ENGLISH 5. APPLICATIONS EVOSTA2, EVOSTA3 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.

MANAGEMENT Storage All the circulators must be stored in a dry covered place, with possibly constant air humidity, free from vibrations and dust.

  • Page 9: Mechanical Installation

    2. Install the pump with a horizontal motor shaft. See fig. 1, pos. C. 3. Tighten the fittings. User Interface Position Always install the EVOSTA2, EVOSTA3 circulator with the motor shaft in a horizontal position. Install the electronic control device in a vertical position.

  • Page 10: Figure 4: Positions Of The User Interface

    ENGLISH − 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.

  • Page 11: Rotation Of The User Interface

    Before rotating the circulator, ensure that it has been completely drained. To rotate the EVOSTA2, EVOSTA3 circulator, proceed as follows: 1. Remove the 4 fixing screws of the circulator head.

  • Page 12: Non-Return Valve

    ENGLISH 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.

    ENGLISH EVOSTA3 Phase Fit nut and connector on the Unscrew the cable gland nut cable. Strip the wires as and extract the terminal board Rotate the terminal board indicated in the figure. Action from the connector, releasing it through 180°. Connect the wires to the from the side clips.

  • Page 15: Start

    Illustration Table 5: Mounting the Evosta2 connector START All the starting operations must be performed with the cover of the EVOSTA2, EVOSTA3 control panel closed. Start the system only when all the electrical and hydraulic connections have been completed.

  • Page 16: Degassing The Pump

    ENGLISH 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. 3) 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 (see par.12).

  • Page 17: Functions

    ENGLISH FUNCTIONS 11.1 Regulating Modes EVOSTA2, EVOSTA3 circulators allow the following regulating modes depending on plant requirements: − Proportional differential pressure regulation depending on the flow present in the plant. − Constant differential pressure regulation. − Regulation with constant curve.
