Manual refers to a maximum pressure, not an operational pressure, ie:"
< 72.5 psi" This is fine for both open and closed loop systems as most
mains operate below this range, and the TNP on most solar pump stations is
set higher than this value.

Hi Carl,
We've installed Apricus systems for about 3 years. I expect that the 72.5
psi = 5 bars, is the recommended system TEST pressure, before charging. We
hold pressure on all our systems at 75 - 80 psi, before charging at 25 to 35
psi. We used to take the test pressure higher, before using pum

I am reviewing the commissioning instructions for the Apricus solar
DHW system. I note that the specified charging pressure for the
glycol loop is 72.5 psi per the manual. This seems high compared to
other systems I have experience with. Can anyone comment on
