Safety Precautions
Cautions before installation
Use the specified cables for wiring. Make the
connections securely so that the outside force
of the cable is not applied to the terminals.
- Inadequate connection and fastening may gen-
erate heat and cause a fire.
Never repair the unit. If the air conditioner
must be repaired, consult the dealer.
- If the unit is repaired improperly, water leakage,
electric shock, or fire may result.
If refrigerant gas leaks during service work,
ventilate the room.
- If the refrigerant gas comes into contact with a
flame, poisonous gases will be released.
Securely install the cover of control box and
the panel.
- If the cover and panel are not installed properly,
dust or water may enter the outdoor unit and fire
or electric shock may result.
If the air conditioner is installed in a small
room, measures must be taken to prevent the
refrigerant concentration from exceeding the
safety limit when the refrigerant leaks.
- Consult the dealer regarding the appropriate
measures to prevent the safety limit from being
exceeded. Should the refrigerant leak and cause
the safety limit to be exceeded, hazards due to
lack of oxygen in the room could result.

Have all electric work done by a licensed
electrician according to "Electric Facility
Engineering Standard" and "Interior Wire

electric work is performed improperly, electric
shock and fire may result.
When installing and moving the air condition-
er to another site, do not charge it with a
refrigerant different from the refrigerant
(R407C) specified on the unit.
- If a different refrigerant or air is mixed with the
original refrigerant, the refrigerant cycle may
malfunction and the unit may be damaged.
When moving and reinstalling the air condi-
tioner, consult the dealer or an authorized
technician.
- If the air conditioner is installed improperly, water
leakage, electric shock, or fire may result.
