There should be a pressure gauge - you want to take it to about 1 bar
(14 psi) while the system is cold. If you need to bleed the radiator, do
that and then check the pressure again. You may need several bites at
the cherry if you are working alone and the rad has lots of air in it.
(if you have a helper - just have them bleed the rad, while you top up
the pressure each every so often).
