Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate
level helps save energy.
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases
the cooling (heating) effect.

4. INSTALLATION SITE

Regarding places for installation
• Is the air conditioner installed at a well-venti-
lated place where there are no obstacles
around?
• Do not use the air conditioner in the following
places.
a. Filled with much mineral oil such as cutting oil
b. Where there is much salt such as a beach
area
c. Where sulfured gas exists such as a hot-spring
resort.
d. Where there are considerable voltage
fluctuations such as a factory or plant
e. Vehicles and vessels
f. Where there is much spray of oil and vapor
such as a cookery, etc.
g. Where there are machines generating
electromagnetic waves.
h. Filled with acid and/or alkaline steam or vapor
• Is a snow protection measure taken?
For details, consult your dealer.
Regarding wiring
• All wiring must be performed by an autho-
rized electrician.
To do wiring, ask your dealer. Never do it by
yourself.
• Make sure that a separate power supply circuit
is provided for this air conditioner and that all
electrical work is carried out by qualified per-
sonnel according to local laws and regulations.
Pay attention to running noises, too
• Are the following places selected?
a. A place that can sufficiently withstand the
weight of the air conditioner with less running
noises and vibrations.
b. A place where the hot wind discharged from
the air outlet of outdoor unit and the running
noises.
• Are you sure that there are no obstacles near
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running noises.
• If abnormal noises occur in use, stop the
operation of the air conditioner, and then con-
sult your dealer or our service station.
Regarding drainage of drain piping
