17.1.2 Additional installation site requirements of the outdoor unit in cold climates
NOTICE
When operating the unit in a low outdoor ambient temperature, be sure to follow
the instructions described below.
▪ To prevent exposure to wind and snow, install a baffle plate on the air side of the
outdoor unit:
In heavy snowfall areas it is very important to select an installation site where the
snow will NOT affect the unit. If lateral snowfall is possible, make sure that the heat
exchanger coil is NOT affected by the snow. If necessary, install a snow cover or
shed and a pedestal.
INFORMATION
For instructions on how to install the snow cover, contact your dealer.
NOTICE
When installing the snow cover, do NOT obstruct the air flow of the unit.
