thermostatic valves, you must ensure that this minimum
water volume is able to circulate.

in the pipes.
Close the drain and bleeder valves and add water until
the pressure in the hydraulic circuit reaches 1 bar.
Check that the hydraulic circuit has been bled correctly.
Check there are no leaks.
After the "Commissioning", page 46 stage, and once the
machine has started, bleed the hydraulic unit again.
" Precise lling pressure is determined by the
water pressure in the installation.
