The magnitude of potential damages or injuries is classified as either a WARNING or a CAUTION.
WARNING
CAUTION
DANGER
WARNING
Do not power the system using an extension cable or with wiring smaller than the specified gauge.
Do not share the electrical circuit with other appliances. Improper or insufficient power supply
can cause undesirable operation, fire, or electrical shock.
Do not allow children to play with or around the air conditioner. Children near the unit must be
supervised at all times.
When connecting refrigerant piping, do not let any 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 also cause explosion and
injury, as well as permament equipment failure. Remember: No dust, humidity or air is allowed to enter.
1.
Installation must be performed by a licensed and trained technician. Defective installation can
cause water leakage, electrical shock, or fire. The usage of proper tools is a requirement.
2. Installation must be performed according to the installation instructions. Improper installation can
cause water leakage, undesired performance, electrical shock, or fire.
(In North America, installation must be performed in accordance with the requirements of NEC and
CEC, by authorized personnel only.)
3.
Contact a qualified and licensed HVAC technician for any repairs or maintenance of this unit.
4.
Only use the included accessories, parts, and specified items for installation. Using non-standard
parts can cause water leakage, electrical shock, fire, and can cause total unit failure.
5. Install the unit on top of a firm structure that can fully support its weight. If the chosen location
cannot support the unit’s weight, or the installation is not done properly, the unit may fall and
cause serious injury and damage.
This symbol indicates that you must never perform the action shown.

Page 5 
6. For all electrical work, follow all local and national wiring standards, regulations, and especially this
Installation Manual. You must use an independent circuit and a dedicated breaker to supply power.
Do not connect other appliances to the same circuit. Insufficient electrical capacity or defects in
electrical work can cause electrical shock or fire.
7. For all electrical work, use the specified cables. Connect cables tightly, and clamp them securely to
prevent external forces from damaging the terminals. Improper electrical connections can overheat
and cause fire, and may also cause shock.
8.
9.
10.
11.
All wiring must be properly arranged to ensure that the control board cover can close properly. If
the control board cover is not closed properly, it can lead to corrosion and cause the connection
points on the terminal to heat up, catch fire, or cause electrical shock.
This appliance can be used by children aged 8 years and above, as well as persons with reduced
physical, sensory, or mental capabilities, or lack of experience or knowledge, if they have been given
supervision or instruction concerning use of the appliance in a safe way, and understand the hazards
involved. Children shall not play with or near the appliance. Cleaning and user maintenance shall
not be done or attempted by children or untrained personnel without proper supervision.
CAUTION
For units that have an auxiliary electric heater, do not install the unit within 1 meter (3 feet) of
any combustible materials.
Do not install the unit in a location that may be exposed to combustible gas leaks. If combustible
gas accumulates around the unit, it may cause fire.
Do not operate your air conditioner in a highly humid space, such as bathrooms or laundry rooms.
Exposure to high humidity or water can cause electrical components to short circuit.
1. The product must be properly grounded at the time of installation, else electrical shock may occur.
2. Install drainage piping according to the instructions in this manual. Improper drainage may cause
water damage to your home and property.
Note about Fluorinated Gasses

and the amount, please refer to the relevant label on the unit itself.
2. Installation, service, maintenance, and repair of this unit must be performed by a certified HVAC
technician.
3. Product uninstallation and recycling must be performed by a certified HVAC technician.
4.
If the system has a leak-detection feature installed, it must be checked for leaks at least every 12
months.
5. When the unit is being checked for leaks, proper logging and record-keeping of all checks is strongly
recommended.
In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed
air-conditioning units is highly recommended. This is intended as a general comfort cooling system.

CAUTION
Regarding the Airflow of the Indoor Unit
The air that is pulled in by the fan (the “return air”) enters the
grille and is passed through the filter. It is then
cooled/dehumidified/heated through the heat exchanger.
The direction of the air output is manipulated up and down by the
motorized louver, and left to right via manually controlled vertical
deflectors. Some models may come with “dual-swing” capability,
which offers both a horizontal and vertical motorized air flow swing.
Controlling the System’s Airflow
1. Pressing the SWING buttons activates the louver.
• Press the Swing button to trigger the horizontal
flaps to swing up and down. Press this button again
to stop swing movement at the current angle.
• Press the Swing button to trigger the vertical
flaps to swing left and right. Press this button again
to stop swing movement at the current angle.
2. If the vertical deflectors (which are located
underneath the flaps) are adjusted manually,
they can be used to fix the airflow in a certain
vertical position before turning the system on.

placed within the room. In some cases, this can
aid with reducing thermal drift between the set
temperature and the actual room temperature.
In order to activate this feature, press the
button, and the icon will appear on the display.
Note: The I FEEL feature will automatically de-activate
itself 2 hours later.
SELF-CLEAN Feature
This feature helps carry away accumulated dust,
dirt, bacteria, and other microbial contents away
from the indoor evaporator.
To activate this feature, press the Swing and
buttons together until a beep is heard from the unit,
and AC is displayed on the unit and remote.
This procedure will run for approximately 30
minutes, before returning to the preset mode.
The button can be pressed to cancel this feature
during the process. Two beeps will be emitted from
the machine when it is finished, or cancelled.
This procedure can result in some uncommon noise
coming from the machine. This noise is normal as a
side effect of the plastics expanding and contracting
due to reactions with heat and cold.
It is recommended to use this function only when
indoor temperature is under 86°F and outside
temperature is between 41°F and 86°F.
It is suggested to run this feature once every 3 months.

HEATING Mode DRYING Mode
Full system-rated capacity and efficiency is obtained at the standard rating conditions as developed by
the testing and rating agencies. Deviations from the rating conditions, especially the atmospheric
conditions, will be compensated by the variable speed compressor, within certain limitations.
Heat pump systems function by exchanging energy, in the form of heat, between the indoor air and
the outdoor ambient air (atmospheric). The system’s net cooling or heating capacities and efficiencies
change by atmospheric conditions, as well as the indoor air conditions (such as temperatures and
humidity levels).
Capacity of the system required for a specific area or application must be determined professionally
using detailed calculations, which are based on several internal and external factors.
To further optimize the performance of your unit, be sure to do the following:
• Keep doors and windows closed.
• Limit energy usage by using TIMER ON and TIMER OFF functions.
• Do not block air inlets or outlets.
• Regularly inspect and clean air filters.
