3. Connect the tank to the heating system and slowly fill it with water until the pressure in the system equals the gas pressure in the expansion tank.

4. Turn on the circulation pump and continue filling the system with water until the initial operating pressure is established at the expansion tank connection point. At this point, the tank will receive the reserve operating volume of water.

1. Fill out the form provided in the section Expansion tank calculation, and as a result of the calculation, you will receive all the necessary parameters for setting up the tank according to the specified conditions.

Series LF007 Lead Free* Double Check Valve Assembly Backflow Preventers are designed to prevent the reverse flow of liquids in a plumbing system due to backpressure or backsiphonage where there is a non-health hazard. Their compact design makes them easy to install in tight spaces. And the single cover, top-entry design allows convenient access for maintenance. The seats and seat discs are replaceable, and no special tools are required for servicing.

2. Expansion tanks are supplied filled with gas. Before connecting the tank to the heating system, set the initial gas pressure in the tank according to the value specified in the calculation results. This may require either lowering the pressure by releasing gas through the valve or using a compressor to pump it through the same valve.

5. After connecting the heat source and switching to the mode with the maximum temperature, each kilogram of heat carrier will increase in volume by the value of the specific volume increase specified in the calculation results, and the expansion tank will receive the heat carrier in a volume equal to the useful capacity of the tank. At this time, the pressure in the tank will rise to the maximum operating pressure specified in its calculation.
