b. Fill the installation slowly until the ll pressure in the expansion vessel is 0.3 bar higher
than the pre-charge. Bleed the system during lling (g. 8).
c. Bleed the pipe to the expansion vessel (g. 8).
d. Close the bleed points (g. 9).
e. Heat the system as high as possible for half a day and bleed regularly.
f. When the water temperature has fallen to approx. 50 °C, top up the installation to 0.5
bar above the pre-charge of the expansion vessel. Ensure that the lling hose is bled.
3. Maintenance and service
It is recommended that the expansion vessel is checked annually by approved personnel.
