• Where it is not exposed to strong wind.

• Whereairowisgoodanddustless.

• Where rain or direct sunshine can be avoided as much as possible.

• Where neighbours are not annoyed by operation sound or hot air.

• Where rigid wall or support is available to prevent the increase of op

eration

sound or vibration.

• Where there is no risk of combustible gas leakage.

• When installing the unit, be sure to secure the unit legs.

• Where it is at least 3 m away from the antenna of TV set or radio. Op

ration of the air conditioner may interfere with radio or TV reception in

areaswherereceptionisweak.Anampliermayberequiredfortheaf-

ected device.

• Install the unit horizontally.

• Please install it in an area not affected by snowfall or blowing snow.

In areas with heavy snow, please install a canopy, a pedestal and/or

somebafeboards.

Note:

is advisable to make a piping loop near outdoor unit so as to reduce

vibration transmitted from there.

TV antenna wire.

The “Q’ty” for (B) to (K) in the above table is quan

tity

to be used per indoor unit.

Units should be installed by licensed contractor according to local code requirements.

After the leak test, apply insulat-

ing material tightly so that there is

no gap.

When the piping is to be at-

tached to a wall containing metals

(tin plated) or metal netting, use

a chemically treated wooden

piece 20 mm or thicker between

the wall and the piping or wrap 7

to 8 turns of insulation vinyl tape

around the piping.

To use existing piping, perform

COOL operation for 30 minutes

and pump down before removing

the old air conditioner. Remake

Note:

When operating the air conditioner in low outside temperature, be sure

to follow the instructions described below.

• Never install the outdoor unit in a place where its air inlet/outlet side

may be exposed directly to wind.

• To prevent exposure to wind, install the outdoor unit with its air inlet

side facing the wall.

•

To prevent exposure to wind, it is recommended to install a baffle

board on the air outlet side of the outdoor unit.

Avoid the following places for installation where air conditioner trouble

is liable to occur.

• Whereammablegascouldleak.

• Where there is much machine oil.

• Whereoilissplashedorwheretheareaislledwithoilysmoke(such

as cooking areas and factories, in which the properties of plastic

could be changed and damaged).

• Salty places such as the seaside.

• Wheresuldegasisgeneratedsuchasahotspring.

• Where there is high-frequency or wireless equipment.

• Where there is emission of high levels of VOCs, including phthalate

compounds, formaldehyde, etc., which may cause chemical crack

ing.

IMPORTANT NOTES

To comply with the requirements of Australian standard AS/NZS 3000

electrical installations (wiring rules), the electrical wiring required

between the indoor and outdoor units must be installed by a licenced

electrical contractor.
