Observe the restrictions on the maximum weight that a person can lift, which is specified
in local regulations.
- Failure to do so may result in injury.
1-3. Precautions for unit installation
Do not install the unit where combustible gas may leak.
- If combustible gas accumulates around the unit, fire or explosion may result.
Do not allow children to play with the packing materials.
- Suffocation or serious injury may result.
Cut up the packing materials before disposal.
All installation work must be performed by qualified personnel in accordance with this
manual.
- Improper installation may result in refrigerant leakage, water leakage, serious injury, electric
shock, or fire.
If the air conditioner is installed in a small room, take measures to prevent the refrigerant
concentration from exceeding the safety limit in the event of refrigerant leakage.
- Consult your dealer regarding the appropriate measures to prevent the allowable concentration
from being exceeded. If the refrigerant leaks and the allowable concentration is exceeded,
hazards due to a lack of oxygen in the room will result.
Install the unit in accordance with the instructions to minimize the risk of damage from
earthquakes and strong winds.
- Improper installation will cause the unit to topple, resulting in serious injury.
The unit must be securely installed on a structure that can sustain its weight.
- Failure to do so will cause the unit to fall, resulting in serious injury. Abnormal vibrations that
result from improper installation can generate abnormal sound and damage the pipes, resulting
in refrigerant gas leakage.
Seal all openings around pipes and wires to keep out small animals, rainwater, or snow.
- Failure to do so may result in current leakage, electric shock, or damage to the unit.
Outdoor unit with salt-resistant specification is recommended to use in a place where it is
subject to salt air.
Even when the unit with salt-resistant specification is used, it is not completely protected
against corrosion.
Salt-resistant unit is resistant to salt corrosion, but not salt-proof.
Install the salt-resistant unit out of direct exposure to sea breeze, and minimize the
exposure to salt water mist.
Periodically wash salt deposits off the unit, especially when the unit is installed in a
coastal area.
Periodically check the unit, and apply anti-rust agent and replace corroded parts as
necessary.
