Refrigerant R410A is non-flammable, non-toxic, and odorless, and may produce toxic gases when exposed to
open flame. Since this refrigerant gas is heavier than air, it may result in lack of oxygen, thereby leading to
breathing difficulties when the area near the ground is filled with this gas. If that's the case, please turn off the
main switch immediately, cut off the power supply, and open the doors and windows for ventilation. Put out any
open flame, and contact your service dealer. Performing leak detection and gas tightness test with oxygen,
acetylene or other flammable and toxic gases may cause explosion, so nitrogen is recommended for this test.
͓
The standards for safe refrigerant leakage in construction and system operation are determined based on local
regulations or standards.
͓
Use ELB with medium or higher sensing speed (ELB with an operating time of 0.1 seconds or less), or
electric shock or fire may arise.
͓
For installation, the refrigerant piping must be firmly connected before the operation of compressor. For repair,
the refrigerant piping must be moved, handled and removed after the stop of compressor.
͓
Please don't short-circuit the protective device (e.g., the pressure switch, etc.) during operation, since this
may cause fire or explosion.

Do not use any sprays such as insecticide, lacquer, hair spray or other flammable gases within approximately
one
3.3ft.(

from the system.
If the earth leakage breaker (ELB) is frequently activated, please stop the system and contact your local dealer
or customer services.
Make sure the ground wire is securely connected. The improper grounding of machine may lead to electrical
failure. Please don't connect the ground wire to gas pipes, tap water pipes, lightning rods or phone ground
wires.
Make sure there are no flammable materials around during brazing operation. Please wear leather gloves to
prevent frostbite when filling refrigerant.
Prevent rats or other small animals damaging the wiring and electrical components. Bitten unprotected parts
may cause a fire.
Firmly fix the connection wires. The external force of terminal may result in looseness of terminal that may
cause a fire.
Make sure the air conditioner is installed with enough strength of fixation; otherwise, the air conditioner may
fall or topple over, which may bring about machine damage or personal injury.
Please follow the installation instructions and related regulations and standards for electrical construction;
otherwise, electrical failure or fire may occur due to inadequate capacity or inconsistent specifications.
Never fail to use specified wiring and select correct wiring, since failure to do so may cause electrical failure or
fire.
Please make sure the outdoor unit is not covered with snow or ice before use.
͓
Please don't perform installation works such as refrigerant piping connection, drain pipe connection, and
wiring connection. Violations may result in system leakage, electrical failure or fire. In the case of fire, please
turn off the power immediately; please don't touch electrical parts with the hands, or electric shock may arise.
Do not pour water into the indoor or outdoor unit. This machine is an electric product that may develop
serious electric failure when exposed to water.
Do not open the service cover of indoor or outdoor units without turning OFF the main power supply;
otherwise, this may bring about serious safety accident.
Do not touch or adjust safety devices inside the indoor or outdoor units. If they are touched or readjusted,
serious accident may arise.
