previously selected mode again.
The set temperature has been reached, at which point the unit turns off the
compressor. The unit will continue operating when the temperature
fluctuates again.
The indoor unit
emits white mist
In humid regions, a large temperature difference between the room’s air
and the conditioned air can cause white mist.
Both the indoor and
outdoor units emit
white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
Troubleshooting
The unit changes from
COOL/HEAT mode to
FAN mode
The indoor unit makes
noises
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor unit
and outdoor unit make
noises
Low hissing sound during operation: This is normal and is caused by refrigerant
gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is
defrosting: This noise is normal and is caused by the refrigerant gas stopping or
changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.
SAFETY PRECAUTIONS
If ANY of the following conditions occurs, turn off your unit immediately!

appropriate location for the unit.
Proper installation locations meet the
following standards:
Good air circulation
If no need the back holder to prop up
the unit:
Finishing the pipe and cable connections
before mount the indoor unit on the wall.
If the instllation height is limited, 1.9in (5cm)
from the ceiling is allowable, but this can
lower product performance. To ensure
enough space to install and remove the top air
filter, keep at least 3.9in (10cm) or more from
the ceiling. Need the back holder to prop
up the unit: If connecting pipe and cable
with front panel open, the minimum distance
from ceiling is 8.6in (22cm) or more, if
connecting pipe and cable without front panel
(remove it) , the minimum distance from
ceiling is 4.3 (11cm) or more.
Convenient drainage
Noise from the unit will not disturb other
people

locations:
Near any source of heat, steam, or
combustible gas
Near flammable items such as curtains or
clothing
Near any obstacle that might block air
circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you
should leave ample room for a wall hole (see
Drill wall hole for connective piping step)
for the signal cable and refrigerant piping
that connect the indoor and outdoor units.
The default position for all piping is the right
side of the indoor unit (while facing the unit).
However, the unit can accommodate piping to
both the left and right.
Refer to the following diagram to ensure
proper distance from walls and ceiling:
NOTE:
Step 2: Attach mounting plate to wall

Note on Pipe Length
Connection Instructions – Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
When connecting refrigerant piping, do not
let substances or gases other than the specified
refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity,
and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and
injury.
1. Measure the distance between the indoor and
outdoor units.
2.
Using a pipe cutter, cut the pipe a little longer than
the measured distance.
3.
Make sure that the pipe is cut at a perfect 90°angle.
Oblique Rough Warped
90°
DO NOT DEFORM PIPE
WHILE CUTTING
Be extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating efficiency
of the unit.
The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal
efficiency is tested on units with a pipe length of 16.5ft (5 meters)(
In North America, the standard pipe
length is 25ft (7.5m)
. A minimum pipe run of 9.8ft (3 meters) is required to minimize vibration &
excessive noise. In special tropical area, for the R290 refrigerant models, no refrigerant can be added
and the maximum length of refrigerant pipe should not exceed 32.8ft (10 meters).
Refer to the table below for specifications on the maximum length and drop height of piping.
