For Reference

If a heating operation would be continuously performed
for a long time under the condition that the outdoor
temperature is 0°C or lower, draining of defrosted water
may be difficult due to freezing of the bottom plate,
resulting in a trouble of the cabinet or fan.

It is recommended to procure an anti-freeze heater
locally for a safety installation of the air conditioner.

For details, contact the dealer.
