To reduce the risk of burns or frost bites, do
not touch the refrigerant pipes or refrigerant
circuit components with bare hands during
and immediately after operation.
To reduce the risk of injury from falling
tools, keep children away while installing,
inspecting, or repairing the unit.
Keep the space well ventilated. Refrigerant
can displace air and cause oxygen starva-
tion. If leaked refrigerant comes in contact
with a heat source, toxic gas may be gener-
ated.
When there is an abnormality (burning
smell, etc.), stop operation and turn off the
power switch. Contact your dealer or cus-
tomer support. There is a risk of electric
shock, failure, and fire if operation is contin-
ued while there is an abnormality.
To reduce the risk of being caught in rotat-
ing parts, electric shock, and burns, do not
operate the unit without all required panels
and guards being installed.
To reduce the risk of injury, do not sit,
stand, or place objects on the unit.
To reduce the risk of water leakage and mal-
functions, do not turn off the power immedi-
ately after stopping operation. Leave the
unit turned on for at least 5 minutes before
turning off the power.
Do not install the unit over things that are
vulnerable to water damage from condensa-
tion dripping.
To reduce the risk of injury, electric shock,
and malfunctions, do not touch or allow ca-
bles to come in contact with the edges of
components.
To reduce the risk of injury, do not touch the
heat exchanger fins or sharp edges of com-
ponents with bare hands.
[2] Transportation and Installation
Transportation and Installation
Lift the unit by placing the slings at desig-
nated locations. Support the outdoor unit
securely at four points to keep it from slip-
ping and sliding. If the unit is not properly
supported, it may fall and cause personal
injury.
To reduce the risk of electric shock, smoke,
and fire due to infiltration of dust and water,
properly install all required covers and pan-
els on the terminal box and control box.
To reduce the risk of injury from units falling
or falling over, periodically check the instal-
lation base for damage.
Consult an authorized agency for the proper
disposal of the unit. Refrigerant oil and re-
frigerant that may be left in the unit pose a
risk of fire, explosion, or environmental pol-
lution.
Always wear protective gears when touch-
ing electrical components on the unit. Sev-
eral minutes after the power is switched off,
residual voltage may still cause electric
shock.
When touching electrical parts, wear pro-
tective gear. There is a risk of a burn if you
touch a high-temperature part. There is a
risk of an electric shock if you touch a high-
voltage part.
To reduce the risk of injury, do not insert fin-
gers or foreign objects into air inlet/outlet
grills. If the unit is left on a damaged base, it
may fall and cause injury.
When performing work, wear protective
gear. There is a risk of an injury.
Do not release refrigerant into the atmo-
sphere. Collect and reuse the refrigerant, or
have it properly disposed of by an autho-
rized agency. Refrigerant poses environ-
mental hazards if released into the air.
