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
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.
By default, the outdoor unit heat pump can operate until –7°C. Depending on the
installation area, this can be lowered to –15°C by modifying the BUH
ambient temp. ([8-0E]) field setting. This setting can also be changed via the
menu structure. See the installation manual of the indoor unit for how to change
the setting.
Additionally, in areas with ambient temperatures between –7°C and –15°C, and
depending on the altitude of the unit, the installation of a bottom plate heater
(EKBPHT03D) may be required to guarantee outdoor unit operation.
