INFORMATION
Start by purging the air out of the unit with the manual air vent valves. Only if water
escapes the valve after opening it, you can start the manual air purge function. When
almost all the air is removed, perform an automatic air purge. If necessary, repeat
performing the automatic air purge until you are sure that all air is removed from the
system. During air purge function, pump speed limitation [9‑0D] is NOT applicable.
Finally open the two manual air purging valves and check if the circuit is sufficiently
filled with water.
The air purge function automatically stops after 30 minutes.
INFORMATION
