.
It may take some time before the fan starts. This is not a
malfunction.

NOTE
■
The heating capacity drops when the outside
temperature falls. If this happens, use another
heating device together with the unit. (When using
together with appliances that produce open fire,
ventilate the room constantly.)
Do not place appliances that produce open fire in
places exposed to the air flow from the unit or
under the unit.
■
It takes some time to heat up the room from the
time the unit is started since the unit uses a hot-
air circulating system to heat the entire room.
■
If the hot air rises to the ceiling, leaving the area
above the floor cold, we recommend that you use
the circulator (the indoor fan for circulating air).
Contact your dealer for details.

Do not turn off power immediately after the unit stops,
