1. Short Duct Specification
•
The indoor unit is provided with air discharge and air intake “knock-out” hole for duct
connection. However the connection of the short duct for air discharge is possible on only
one side.
•
The use of short duct for air discharge will improve airflow distribution if there is an
obstruction (such as a lighting fixture) or in a long, narrow room or an L-shaped room. It
also use for air-conditioning of two rooms simultaneously.
Note:
•
Avoid using the short duct on which the air discharge grille can be completely closed, to
prevent evaporator freezing.
•
In order to prevent condensation forming, be sure that there is sufficient thermal insulation
and no leakage of cool air when installing the short duct.
•
Keep the introduction of fresh air intake within 20% of total air flow. Also provide a
chamber and use a booster fan.
2. Sealing Material
•
It is possible to seal one of the
four air discharge outlet.
(Sealing two or more air
discharge outlet could cause a
malfunction.)
•
Remove the front panel and
insert the sealing material into
the air discharge outlet on the
indoor unit to seal the air
outlet.
•
The sealing material is the
same length as the longer air
discharge outlet. If it is desired
to seal the shorter air discharge
outlet, cut the sealing material
to shorten it.
•
Push the sealing material in
about 10mm beyond the
bottom surface of the indoor
unit so that it does not touch
the air louver. Be sure not to
push the sealing material in
any farther than about 10mm.
AUTO RANDOM RE-START FUNCTION
If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is
restored. (Applicable only to units with this feature.)
