Typical workflow
Purging the air from the system should consist of:
1 Performing a manual air purge for both zones
2 Performing an automatic air purge for both zones
INFORMATION
Start by performing a manual air purge. 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.
The air purge function automatically stops after 30 minutes.
