Safety Precautions
Read Safety Precautions Before Installation
Incorrect installation due to ignoring instructions can cause serious damage or injury.
The seriousness of potential damage or injuries is classied as either a WARNING or CAUTION.
This symbol indicates that ignoring instructions may cause death or
serious injury.
This symbol indicates that ignoring instructions may cause moderate
injury to your person, or damage to your unit or other property.
This symbol indicates that you must never perform the action indicated.
When connecting refrigerant piping, do not let substances or gases other than the specied
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.
Do not allow children to play with the air conditioner. Children must be supervised around
the unit at all times.
1. Installation must be performed by qualied personnel, according to the installation
instructions. Defective installation can cause water leakage, electrical shock, or re. (In North
America,installation must be performed in accordance with the requirement of NEC and CEC
by authorized personnel only.)
2. Contact an authorized service technician for repair or maintenance of this unit.
3. Only use the included accessories, parts, and specied parts for installation. Using non-
standard parts can cause water leakage, electrical shock, re, and can cause the unit to fail.
4. Install the unit in a rm location that can support the unit’s weight. If the chosen location
cannot support the unit’s weight, or the installation is not done properly, the unit may drop
and cause serious injury and damage.
5. For all electrical work, follow all local and national wiring standards, regulations, and the
Installation Manual. You must use an independent circuit and single outlet to supply power.
Do not connect other appliances to the same outlet. Insucient electrical capacity or defects
in electrical work can cause electrical shock or re.

Note about Fluorinated Gasses
WARNING
CAUTION
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 re.
Do not operate your air conditioner in a wet room such as a bathroom or laundry room. Too
much exposure to water can cause electrical components to short circuit.
1. The product must be properly grounded at the time of installation, or 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.
1. This air-conditioning unit contains uorinated gasses. For specic information on the type of gas

6. For all electrical work, use the specied cables. Connect cables tightly, and clamp them
securely to prevent external forces from damaging the terminal. Improper electrical
connections can overheat and cause re, and may also cause shock.
7. 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 re, or cause electrical shock.
8. In certain functional environments, such as kitchens, server rooms, etc., the use of specially
designed air-conditioning units is highly recommended.
9. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualied persons in order to avoid a hazard.
10. This appliance can be used by children aged from 8 years and above and persons with
reduced Physical, sensory or mental capabilities or lack of experience and knowledge if they
have been given supervision or instruction concerning use of the appliance in a safe way and
