INFORMATION
ONLY applicable for Class 50 units.
In heavy snow areas, snow may cover the outdoor unit, a snowdrift pile may be
formed near the outdoor unit, or icicles may reach the outdoor unit during the
night. If such conditions are left uncorrected, operating the air conditioner in the
next morning can cause damage to the outdoor unit fan or result in fan lock error,
disallowing proper heating operation in some cases.
In this case the snowfall prevention setting can be used.
Prerequisite: Stop the unit operation via the user interface.
Prerequisite: Turn OFF the respective circuit breaker.
Prerequisite: Remove the required plate work, see Plate work.
1 Cut the jumper J12 on the main PCB using nippers or a similar tool to start the
outdoor unit fan intermittently at low ambient.
