INFORMATION
▪
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.
