Defrost operation
• In heating operation, freezing of the outdoor unit's
air cooled coil increases over time, restricting the
energy transfer to the outdoor unit's coil. Heating
capability decreases and the system needs to go
into defrost operation to be able to deliver enough
heat to the indoor units.
• The indoor unit will stop fan operation,
the refrigerant cycle will reverse and energy
from inside the building will be used to defrost
the outdoor unit coil.
• The indoor unit will indicate defrost operation on
the displays " ".
Hot start
• In order to prevent cold air from blowing out of
an indoor unit at the start of heating operation,
the indoor fan is automatically stopped.
The display of the user interface shows "
It may take some time before the fan starts.
This is not a malfunction.
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.
