Checks can be performed in two ways. Either by leak detection at 0.75-1.0 bar over 15 min.,
• Check the glycol mix in the expansion tank. The level must be approx. 1 cm above the MIN. line
(Fig. 23) when the system is cold. Make sure the system is properly vented before running it.
• Check that the circulation pump rpm are correctly set; see section 7. Installing pumps
in the expansion tank sloshes around and it sounds as if pump rpm are set too high, reduce circula-
tion pump rpm.
