These Are Not Malfunctions
•
A softer “hiss” sound occurs
The sound is caused by temperature changes, plastic expansion, etc.
•
Condensation on panel and horizontal louver
Condensation may occur if the horizontal louver that control the wind direction up and down are below the horizontal
angle and the vertical louver that control the wind direction left and right are operated at a position other than the front for
a long time during cooling or heating.
In addition, condensation may also occur when cooling mode and dehumidification mode are operated in a high humidity
environment.
•
No cooling or no heating
If the horizontal louver that control the wind direction up and down are downward and the vertical louver that control the
wind direction left and right are tilted for a long time, the cooling or heating performance may be affected.
•
Machine noise
When the heating mode is operated under high outdoor temperature, the machine will start the protection control function
and make noise.
•
The fan and the louvers of the indoor unit in the stopped state start to operate
In order to ensure product performance and functional requirements, the fan and the louvers of the indoor unit in a
stopped state in the same system sometimes operate.
(Compliance with control requirements, not machine failure)

Installation
WARNING
•
In order to avoid incomplete combustion, do not place the combustion device at the air outlet.
•
Please fit the air outlet at a distance of 1.5 m or more from the fire alarm. Otherwise, in case of a fire, the fire alarm may be
delayed or malfunction.
•
Please ensure there are no obstacles around the air outlet.
•
Please install it directly below the air outlet where there are no obstacles such as decorative ceiling or curtain boxes.
Otherwise, it may lead to obstacles and 3DW Diffusor condensation or dirt, and may affect the cooling and heating
performance.
•
Please make sure both cold and warm air can circulate evenly in the location of installation.
•
Installation under high humidity conditions
The product has passed the condensation test and is confirmed to be normal. However, water dripping may occur during
continuous operation under high humidity conditions. Especially in the following installation places, it is possible to form
high humidity air (dew point temperature above 23 °C).
1) A place near the window
2) A place near the entrance and exit door
3) Kitchen
4) A place where the 3DW Diffusor is exposed to the outdoor air directly
In the above places, please paste heat insulation materials such as sponges on the panel and the horizontal louver of 3DW
Diffusor that are exposed to high humidity air.
[Reference] Test conditions for condensation
Indoor: Dry ball temperature 27 °C
Wet ball temperature 24 °C
Air volume: Low
Running time: 4 hours
