• Never pull or twist the electric wire of the remote controller.

It may cause the unit to malfunction.

• Do not place appliances which produce open fire in

places exposed to the air flow from the unit or under the
indoor unit. It may cause incomplete combustion or
deformation of the unit due to the heat.

• Arrange the drain pipe to ensure smooth drainage.

Incomplete drainage may cause wetting of the building,
furniture etc.

• Do not place the controller exposed to direct sunlight.

The LCD display may get discolored, failing to display the data.

• Do not wipe the controller operation panel with benzine,

thinner, chemical dustcloth, etc.

The panel may get discolored or the coating peeled off. If it is
heavily dirty, soak a cloth in water-diluted neutral detergent,
squeeze it well and wipe the panel clean. And wipe it with
another dry cloth.

• Dismantling of the unit, treatment of the refrigerant, oil

and eventual other parts, should be done in accordance
with the relevant local and national regulations.

• Do not dry the filter by exposing it to direct sunlight or

warming it using fire, etc. Doing so can result in the
deformation of the filter.

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 authorized electrician.

To do wiring, ask your dealer. Never do it by yourself.

• Make sure that a separate power supply circuit is pro-

vided for this air conditioner and that all electrical work
is carried out by qualified personnel 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 the outdoor unit and the running noises.

• Are you sure that there are no obstacles near the air out-

let of the outdoor unit?

Such obstacles may result in declined performance and
increased running noises.

• If abnormal noises occur in use, consult your dealer.

Regarding drainage of drain pipe

• Is the drain pipe executed to perform complete drainage?

If proper drainage is not carried out from the outdoor drain
pipes during air-conditioning operation, chances are that
dust and dirt are clogged in the pipe. This may result in a
water leakage from the indoor unit. Under such circum-
stances, stop the operation of the air conditioner, and then
consult your dealer or our service station.
