It is recommended to provide at least 150 mm of free space below the unit

(300mm for heavy snowfall areas). Additionally, make sure the unit is positioned at

least 100mm above the maximum expected level of snow. If necessary, construct

a pedestal. See "6.3Mounting the outdoor unit"[430] for more details.

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.
