SolarBloC® maxi Basic return station
Low-Flow (= 0.25 l/minute per m² collector surface), up to 125 m² collector surface
High-Flow (= 0.5 l/minute per m² collector surface), up to 80 m² collector surface
Please note:
In order to guarantee a trouble-free function it is essential to carry out a hydraulic dimensioning/check.
All connections ¾" internal thread
Premounted on steel wall bracket,
can be easily mounted to the wall with snap-in mechanism
Full port ball valves
Check valve in the return, can be opened, 200 mm wc, especially for solar systems.In order to prevent unwanted circulation, it is mandatory to mount an additional check valve in the flow on site (see below the item).
Ball valve key-actuated,
easy handling, no risk of scalding
Compact design insulation with optimised function made of durable elastic EPP;
100 % insulated valves and fittings, excellent ventilation and cooling of the pump
Solar safety group
Solar pressure relief valve 6 bars, pressure gauge resistant to high temperature 0-6 bars with valve, fill and drain valve for flushing and filling, flat sealing connection for an expansion tank
Full metal solar thermometer, 0-160 °C
can be pulled off, with immersion sleeve, integrated in the ball valve
Fully assembled with flat gaskets
With solar circulation pump by Grundfos or Wilo
already installed
Pump can be isolated,
so that it can be replaced without draining
Flowmeter
Volumetric flow meter with adjustable flow limiter and function control device, for temperatures up to 120 °C, measuring range 3-22 l/min
Flush and fill unit integrated
two fill and drain valves (on the flowmeter and on the safety group) permit flushing and filling the system
Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. The following must be observed during installation and commissioning: - relevant local and national regulations - accident prevention regulations of the professional association - instructions and safety instructions mentioned in these instructions.
WARNING Danger of scalding due to the escape of hot fluids! With pressure relief valves, there is a risk of scalding due to the escape of vapour or hot fluid. Please ensure for each pressure relief valve that no personal injury or material damage may occur due to possibly escaping medium. - Install a discharge line. - Observe the instructions regarding the pressure relief valve. - The pressures for the expansion tank calculated by the plant designer and the operating pressure of the installation must be set.
CAUTION Personal injury and material damage due to overpressure! Closing both ball valves in the primary circuit will separate the safety group from the heat exchanger. A rise in temperature in the storage tank may result in high pressures, which may lead to personal injury and material damage! - Only close the ball valves for service and maintenance. CAUTION Risk of burns! Valves, fittings and pump may heat up to more than 100 °C during operation. The insulating shell must remain closed during operation.
NOTICE Material damage due to mineral oils! Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant properties get lost. We do not assume liability nor provide warranty for damage to property resulting from sealants damaged in this way. - It is imperative to avoid that the EPDM sealing elements of the unit get in contact with substances containing mineral oils. - Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
