For reference
If a heating operation is to be continuously performed
for a long time under the condition that the outdoor
temperature is 0°C or lower, draining defrosted water
may be dif
fi
cult due to the bottom plate freezing,
resulting in trouble with the cabinet or fan.
It is recommended to procure an anti-freeze heater
locally in order to safely install the air conditioner.
For details, contact the dealer.
