1. Product Description

1.1 Overview

  • SR11H/SR21H EPP solar workstation is used in a split pressurized solar water heater system.

  • It can be used in combination with SR658/SR1568.

  • It combines versatility into one,such as flow control, heat cycle, exhaust, pressure control, temperature display, system injection / drain.

  • By connecting solar collectors and split pressurized water tanks,store solar energy in a water tank.It can monitor system temperature, pressure, flow and other conditions at any time. The whole set of components is compact in structure, easy to install and use, high temperature resistant and good heat preservation effect.

1.2 Main functions


1.2.1 Flushing and filling the solar system

Flushing and filling unit is already integrated in the solar pump station, but we still recommend installing flushing and filling ball valve at the lowest point of the solar circuit in order to drain off the scales.


1.2.2 Flow check

The flow counter is used for measurement and display of flow rate, in order to guarantee the flawless function of the measuring device the system must be flushed and free from foreign substances.


1.2.3 Manual / Automatic integrative air bleeder

After system is filled and commissioned, air vent will automatically release the air of system, but you can also release the air manually.


1.2.4  Electrical connection and operation instruction of controller (see manual of controller)

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)
