Start temperature at system filling 10°C.

CAUTION

– For systems with water content exceeding the max-

imum system content (as indicated in the table) an

additional expansion vessel must be prearranged.

– The difference in height between the relief valve

and the highest point of the system cannot exceed

6 metres. If the difference is greater than 6 metres,

increase the prefilling pressure of the expansion

vessel and the system when cold by 0.1 bar (10 kPa)

for each meter increase.
