1. Product Description
Flushing and filling connector is already integrated in the solar station, and we still recommend installing a filling and drainage valve horizontally at the lowest point of the solar circuit for flushing system.
The flow counter is used for measurement and display of flow rate 1-20L/M, in order to guarantee the flawless function of the measuring device the system must be flushed and free from foreign substances.
The controller is already integrated in the station and ready to plug in, display and digital counter are already preinstalled at factory. For maintenance or service work, it needs to take out the controller from station. For further information on electrical connection of the controller, please see manual of controller (terminal layout).
