Product Description SR11L EPP Solar Work Station & Pump Stations1. Produuct Introduction1.1 OverviewSR11L EPP solar workstation is used in a split pressurized solar water heater system.It can be combined with the SR258 controller.It combines flow control, heat cycle, exhaust, pressure control, temperature display, system injection/discharge and many other functions into one.By connecting solar collectors and split pressurized water tanks, store solar energy in the water tank.It can monitor system temperature, pressure, flow, etc. at any time.The structure of the entire assembly is compact, easy to install and use, good insulation effect.1.1.2 Kits Parameter1Non-return valve:opening pressure 200mmH2O2Connector of flow outlet(to collector):3/4'IT3Safety valve:6bar4Filling connector5Connector of expansion evssel6Manometer:0-6bar7Sensor on return pipe (from tank to collector),NTC10K(optional)8Circuit pump:Wilo 15-6 or Groundfos 15-659Connector of drainage valve10Digital flow counter Return outlet connection(from collector):3/4 IT11Connector of flow inlet (from tank):3/4' IT12Connector of flow outlet(to tank):3/4'IT(no this connector on SR11L station)13Air separator14Manual air bleeder15Sensor on flow pipe (from collector to tank),NTC10K(optional)(no sensor on SR11L station)16Connection of flow inlet(from collector);3/4'IT1.2 Main functions1.2.1 Flushing and filling the solar systemFlushing 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.1.2.2 Flow checkThe 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.1.2.3 Manual / Automatic integrative air bleederAfter filling solar liquid and commissioning the system, air bleeder will release air automatically, but you can also release 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).1.3 Delivery scopeComponentsQuantitiesRemarksSolar pump station1pcSR11Lintegrated solar controller1pcSR258Wall mounting bracket1pc Mounting accessories1bag User manual1pc 2.
