How to charge Heating system to 1.2 Bar
Make sure that you find the filling loop, pressure gauge and the filling loop isolation valves or lets call it filling valves with usual butterfly knobs in Black colour. Okey now.. make sure you understand the dial gauge calibaration.. may be marked psi or Bar or maybe borth. Using the Red indicator ( set pressure indicator) set the pressure to 1.2 bar. Now open each filling valves ( normally open when they are parallel to the pipe) and listen to the sound of the water filling..and keep your eyes on the dial and the hand on the filling valve. When it reaches 1.2 bar as we have set by red indicator close the filling valve. then close the other filling valve. Cool.. Job done.
