This air conditioner uses power supply
:
208/230V ~/60Hz.
Please read these SAFETY PRECAUTIONS carefully to ensure correct installation.
·
Be sure to use a dedicated power circuit, and do not put other loads on the power supply.
·
Be sure to read these SAFETY PRECAUTIONS carefully before installation.
·
Be sure to comply with SAFETY PRECAUTIONS of installation manual, because it contains

We recommend that this air conditioner be installed properly by qualified installation technicians in
accordance with the installation instructions provided with the unit.
Incomplete installation could cause damage by fire, electric shock, drop or water leakage.
·
Wiring must be done by a qualified electrician.
·
Install the air conditioner on a solid base that can support the unit weight.
An inadequate base or incomplete installation may cause injury in the event the unit falls off from
the base.
·
Use the specified type of wire for safe electrical connections.
Firmly clamp the interconnecting wires so that their terminals receive no external stress.
Incomplete connection may cause fire.
·
For wiring, use a cable long enough to cover the entire distance with no connection, and don’t
connect multiple devices to the same AC power supply.
Otherwise, it may result in bad contact, poor insulation, unallowable current, which could finally result
in fire or electric shock.
·
After all installations are completed, check to make sure that no refrigerant leakage occurs.
It will generate harmful substances if the refrigerant gas leaks in the interior area and has contact
with heater or stove flame.
·
Perform the installation securely by referring to the installation manual.
Incomplete installation could cause a personal injury arising from fire, electric shock, unit falling or
water leakage.
·
In accordance with the installation instructions for electrical work, please be sure to use a dedicated
line.
·
If the power supply circuit capacity or electrical work is not in place, it may cause a fire or electric
shock.
·
Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
·
If the electrical covers on the indoor unit or the service panel of the outdoor unit are not attached
securely, it could result in a fire or an electric shock due to dust water, etc.
·
Please be sure to cut off the main power supply before the installation of indoor electronic PCB or
wiring. Otherwise, it will cause electric shock.
·
The device should be in accordance with the state provisions for installation wiring.
·
Pay attention to protecting the outdoor unit installation location. Avoid people or other small animals
damaging electrical components. Please keep the surrounding environment of the outdoor unit
clean and tidy.
·
When installing or relocating the unit, make sure that no substance other than the specified
refrigerant (R410A) enters the refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal pressure rise or an explosion.
