Outdoor Unit Fault - Fujitsu WATERSTAGE WOYG160LJL Maintenance Document

▼ Outdoor Unit Fault

When the system is switched back on after a power
outage, the Hydraulic Unit may display fault 370 for
a few tens of seconds. This is not a serious problem.
It simply means that the outdoor unit is running its
tests. Once the tests have been completed, the fault
should disappear. If it doesn't, if a fault has occurred
on the outdoor unit as indicated by the Hydraulic Unit,
you must remove the front (right-hand) facing from
the outdoor unit. Faults are coded by LED fl ashes.
Error messages are listed in the table below:
