R32 refrigerant warning
This product uses R32
di󰘱uoromethane refrigerant, which
is a mildly 󰘱ammable gas class
2.2 according to ISO 5149 and
must be handled by a refrigeration
mechanic with appropriate
refrigerant handling licence.
F-Gas
Refrigerant: R32;
Refrigerant leakage contributes to
climate change. Refrigerant with lower
global warming potential (GWP) would
contribute less to global warming than
a refrigerant with higher GWP, if leaked
to the atmosphere. This appliance
contains a refrigerant 󰘱uid with a GWP
equal to 675. This means that if 1 kg
of this refrigerant 󰘱uid would be leaked
to the atmosphere, the impact on global
warming would be 675 times higher than
1 kg of CO2, over a period of 100 years.
Never try to interfere with the refrigerant
circuit yourself or disassemble the
product yourself and always ask
a professional. The product or equipment
contains 󰘱uorinated greenhouse gases,
and the 󰘱uorinated greenhouse gases
are contained in hermetically sealed
equipment.

6.3 Notes On Drilling Hole
In Wall
You must drill a hole in the wall for the
refrigerant piping, and the signal cable that
will connect the indoor and outdoor units.
1. Determine the location of the wall
hole based on the location of the
outdoor unit.
2. Using a 65-mm (2.5″) core drill, drill
a hole in the wall.
NOTE: When drilling the wall hole,
make sure to avoid wires, plumbing,
and other sensitive components.
3. Place the protective wall cu󰘯 in the
hole. This protects the edges of the
hole and helps seal it when you 󰘰nish
the installation process.
6.4 When Select a 24K Indoor
Unit
The 24K indoor unit can only be connected
with an A system. If there are two 24K
indoor units, they can be connected with

7. REFRIGERANT PIPING CONNECTION
7.1 Safety Precautions
WARNING
• All 󰘰eld piping must be completed
by a licensed technician and
must comply with the local and
national regulations.
• When the air conditioner is
installed in a small room,
measures must be taken
to prevent the refrigerant
concentration in the room from
exceeding the safety limit in the
event of refrigerant leakage.
If the refrigerant leaks and its
concentration exceeds its proper
limit, hazards due to lack of
oxygen may result.
• When installing the refrigeration
system, ensure that air, dust,
moisture or foreign substances
do not enter the refrigerant
circuit. Contamination in
the system may cause poor
operating capacity, high
pressure in the refrigeration
cycle, explosion or injury.
• Ventilate the area immediately
if there is refrigerant leakage
during the installation. Leaked
refrigerant gas is both toxic
and 󰘱ammable. Ensure there
is no refrigerant leakage after
completing the installation work.
7.2 Refrigerant Piping
Connection Instructions
CAUTION
• The branching pipe must be
installed horizontally. An angle
of more than 10° may cause
malfunction.
• DO NOT install the connecting
pipe until both indoor and outdoor
units have been installed.
• Insulate both the gas and liquid
piping to prevent water leakage.
Step1: Cut pipes
When preparing refrigerant pipes,
take extra care to cut and 󰘱are them
properly. This will ensure e󰘲cient
operation and minimize the need
for future maintenance. For R32/
R290 refrigerant models, the pipe
connection points must be placed
outside of room.
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.
CAUTION
DO NOT deform pipe while cutting.
Be extra careful not to damage,
dent, or deform the pipe while
cutting. This will drastically reduce

8.1 Safety Precautions
WARNING
• Be sure to disconnect the power
supply before working on the
unit.
• All electrical wiring must be
done according to local and
national regulations.
• Electrical wiring must be
done by a quali󰘰ed technician.
Improper connections may
cause electrical malfunction,
injury and 󰘰re.
• An independent circuit and
single outlet must be used for
this unit. DO NOT plug another
appliance or charger into the
same outlet. If the electrical
circuit capacity is not enough or
there is a defect in the electrical
work, it can lead to shock, 󰘰re,
unit and property damage.
• Connect the power cable to the
terminals and fasten it with a
clamp. An insecure connection
may cause 󰘰re.
• Make sure that all wiring is
done correctly and the control
board cover is properly installed.
Failure to do so can cause
overheating at the connection
points, 󰘰re, and electrical shock.
• Ensure that main supply
connection is made through a
switch that disconnects all poles,
with contact gap of a least 3mm
(0.118″).
• DO NOT modify the length of the
power cord or use an extension
cord.
CAUTION
• Connect the outdoor wires
before connecting the indoor
wires.
• Make sure you ground the unit.
The grounding wire should be
away from gas pipes, water
pipes, lightning rods, telephone
or other grounding wires.
Improper grounding may cause
electrical shock.
• DO NOT connect the unit with
the power source until all wiring
and piping is completed.
• Make sure that you do not cross
your electrical wiring with your
signal wiring, as this can cause
distortion and interference.
Follow these instructions to prevent
distortion when the compressor starts:
• The unit must be connected to the
main outlet. Normally, the power
supply must have a low output
impedance of 32 ohms.
• No other equipment should be
connected to the same power circuit.
• The unit’s power information can be
found on the rating sticker on the
product.
TAKE NOTE OF FUSE SPECIFICATIONS
