As long as space like the one

shown in the figure can be

maintained, it does not mat-

ter if there are obstacles in

three directions (but top side

is open).

The unit can be used by at-

taching an optional outdoor

blowing guide (MAC-889SG)

(but both sides and top are

open).

The diameter of connection pipes differs according to the type and capacity of indoor units. Match the diameters of connection pipes for indoor and outdoor

units according to the following table.

•  If the diameter of connection pipes does not match the diameter of pipe end connections, use optional different-diameter joints.

•  Where it is not exposed to strong wind.

•  Where airflow 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 at a high level, be sure to secure the unit legs.

•  Where it is at least 3 m (9.84 ft) away from the antenna of TV set or

radio. Operation of the air conditioner may interfere with radio or TV re-

ception in areas where reception is weak. An amplifier may be required

for the affected 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 baffle boards.

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

vibration transmitted from there.

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 flammable gas could leak.

•  Where there is much machine oil.

•  Salty places such as the seaside.

•  Where sulfide gas is generated such as a hot spring.

•  Where there is high-frequency or wireless equipment.

•  When installing the unit in an area that is enclosed on four sides such

as a verandah, be sure to leave move than 200 mm (7.87 in.) behind

the unit as shown.

•  When  there  is  a  lack  of  airflow  or  there  is  a  possibility  of  becoming

short  cycle,  install  an  outlet  guide  and  make  sure  there  is  enough

space behind the rear side of the air inlet.

Make sure not to install several outdoor units sideways next to each

other.

there is an obstacle over the top side

as shown in the figure below.

In this case, the rear, both sides and

top should be open.

nance.
