Installation Location
•We recommend that this air conditioner be installed properly by
qualified installation technicians in accordance with the Installation
Instructions provided with the unit.
•Before installation, check that the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.
•Do not install this air conditioner where there are fumes or flammable
gases, or in an extremely humid space such as a greenhouse.
•Do not install the air conditioner where excessively high heat-
generating objects are placed.
Avoid: To protect the air conditioner from heavy corrosion, avoid installing the
outdoor unit where salty sea water can splash directly onto it or in
sulphurous air near a spa.
Electrical Requirements
1. All wiring must conform to the local electrical codes. Consult your
dealer or a qualified electrician for details.
2. Each unit must be properly grounded with a ground (or earth) wire or
through the supply wiring.
3. Wiring must be done by a qualified electrician.
Safety Instructions
•Read this Instruction Manual carefully before using this air conditioner.
If you still have any difficulties or problems, consult your dealer for
help.
•This air conditioner is designed to give you comfortable room
conditions. Use this only for its intended purpose as described in this
Instruction Manual.
•Never use or store gasoline or other flammable vapor or liquid near
the air conditioner — it is very dangerous.
•This air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you use
gas or oil heating appliances in the same room, which
consume a lot of oxygen from the air. Otherwise there is a risk of
suffocation in an extreme case.
CAUTION •Do not turn the air conditioner on and off from the power mains
switch. Use the ON/OFF operation button.
•Do not stick anything into the air outlet of the outdoor unit. This is
dangerous because the fan is rotating at high speed.
•Do not let children play with the air conditioner.
•Do not cool the room too much if babies or invalids are present.

NOTE The remote control unit sends the temperature signal to the air conditioner regularly at five minute intervals.
If the signal from the remote control unit stops for more than ten minutes due to the loss of the remote
control unit or other trouble, the air conditioner will switch to the temperature sensor which is built into
the indoor unit and control the room temperature. In these cases, the temperature around the remote
control unit may differ from the temperature detected at the air conditioner’s position.
