Safety Precautions
Be sure to use a dedicated power circuit. Never use a power
supply shared by another appliance.
For wiring, use a cable length enough to cover the entire
distance with no connection. Do not use an extension cord. Do
not put other loads on the power supply, use a dedicated power
circuit. (Failure to do so may cause abnormal heat, electric
shock or fire.)
Use the specified types of wires for electrical connections
between the indoor and outdoor units. Firmly clamp the
interconnecting wires so their terminals receive no external
stresses. Incomplete connections or clamping may cause
terminal overheating or fire.
After connecting interconnecting and supply wiring be sure
to shape the cables so that they do not put undue force on
the electrical covers or panels. Install covers over the wires.
Incomplete cover installation may cause terminal overheating,
electrical shock, or fire.
If any refrigerant has leaked out during the installation work,
ventilate the room. (The refrigerant produces a toxic gas if
exposed to flames.)
After all installation is complete, check to make sure that no
refrigerant is leaking out. (The refrigerant produces a toxic gas
if exposed to flames.)
When installing or relocating the system, be sure to keep the
refrigerant circuit free from substances other than the specified
refrigerant (R410A), such as air. (Any presence of air or other
foreign substance in the refrigerant circuit causes an abnormal
pressure rise or rupture, resulting in injury.)
During pump-down, stop the compressor before removing the
refrigerant piping. If the compressor is still running and the stop
valve is open during pump-down, air will be sucked in when the
refrigerant piping is removed, causing abnormal pressure in the
freezer cycle which will lead to breakage and even injury.
