Bleeding and filling system with coolant
Its easiest to fill ducting starting from the lowest point of installation. If you start filling from the header tank there will
be airlocks. Filling from the lowest point takes most of the air out from the system, so this makes bleeding much
easier. If there is air in the ducting heater does not work correctly.
Premix enough coolant according to manufacturers instructions ( Standard recommendation is 30% antifreeze, 70%
water in Finland)
1) Install T-branch to the lowest point of coolant ducting
