Page 14: Checking The Water Volume And Expansion Vessel Pre-Pressure
Checking the water volume and expansion vessel Using the table and instructions below, determine if the total water volume in the installation is below the maximum allowed pre-pressure water volume. The unit is equipped with an expansion vessel of 12 litre which has a default pre-pressure of 1 bar. -
Page 15: Setting The Pre-Pressure Of The Expansion Vessel
Result: Precautions when connecting field piping and regarding Since 380 l is higher than 180 l or 270 l, the pre-pressure must insulation be decreased (see table above). The required pre-pressure is: The complete water circuit, inclusive all piping, must be insulated to Pg=(H/10+0.3) bar=(0/10+0.3) bar=0.3 bar prevent reduction of the heating capacity. -
