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 heatgenerating 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
4
• 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 or heat the room too much if babies or invalids are
present.

• ‘‘DRY’’ operation is not possible if the indoor temperature is 15 °C or less.
Heating ( ) Operation
Heating performance • Because this air conditioner heats a room by drawing in the heat of the
outside air (heat pump system), the heating efficiency will fall off when the
outdoor temperature is very low. If sufficient heat cannot be obtained with
this air conditioner, use another heating appliance together with it.

outdoor temperature and the way in which frost forms.)
at lower speed until the indoor heat exchanger coil has warmed up
sufficiently. However, the fan may remain stopped when the room
temperature is low. This is because the COLD DRAFT PREVENTION
SYSTEM is operating.
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically within five minutes by the
remote control unit.
• In heating or cooling operation, any plastic parts may expand or shrink due
to a sudden temperature change. In this event, a clicking sound may occur.
This is normal, and the sound will soon disappear.

Care and Cleaning
1. For safety, be sure to turn the air conditioner off and also to
disconnect the power before cleaning.

Casing and Grille (Indoor Unit) Clean the casing and grille of the indoor unit with a vacuum cleaner brush, or
wipe them with a clean, soft cloth.
If these parts are stained, use a clean cloth moistened with a mild liquid
detergent. When cleaning the grille, be careful not to force the vanes out of
place.
CAUTION
1. Never use solvents, or harsh chemicals when cleaning the indoor
unit. Do not wipe the plastic casing using very hot water.
2. Some metal edges and the fins are sharp and may cause injury if
handled improperly; be especially careful when you clean these
