Circulator (Aqua Stove)

This text briefly describes the installation and commissioning instructions for the EVOSTA2 OEM circulators, highlighting some key steps to ensure their proper operation.
Here is a summary and operational explanation step by step (see manual):

Function of the circulator

The circulators of the EVOSTA2 OEM series feature integrated differential pressure control, which allows adjusting performance based on the actual needs of the system.

 

System preparation

Before installing the circulator, it is essential to thoroughly clean the system:

• Perform a flush with water only at 80°C to remove residues, oils, sludge, and impurities.
• Then, completely drain the system to eliminate any harmful substances that could compromise the circulator's durability or performance.

💡 This step is essential to avoid damage to the seals, rotor, or pump electronics.

Installation

After cleaning:

• Make all electrical and hydraulic connections according to the manufacturer's specifications.
• Fill the system with clean water, ensuring there are no air bubbles.
• Electrically power the system.

Pump degassing (see manual)

1. Always vent the pump before starting!
2. The pump must not run dry.

Start-up and adjustment

Once the circulator is started, it is possible to change the operating modes to optimize performance based on the type of system or leave the default settings.
