INSTALLATION
[About the location to install]
• The unit should be installed at a place with good ventilation
and no obstacle.
• Do not use the unit at any of the following locations:
a. where mist of such mineral oil as machining oil, etc. is
enveloping
b. where thick salty mist is enveloping such as seaside area
c. where sulfuric gas is enveloping such as hot spring area
d. where frequent voltage variation is expected such as fac-
tories
e. installation on a vehicle or vessel
f. where large spray of oil or steam is expected such as a
kitchen
g. where a machine that generates electromagnetic wave is
installed
h. where acid or alkali steam is enveloping
• Keep TV, radio, stereo, etc. 1 meter or more apart from the
indoor unit, the outdoor unit, electric wires, connecting wires
and pipes. Otherwise the image may be blurred or noise
may be invited.
• Take proper countermeasures against snow.
• Place the unit so that the outlet vent does not blow air
directly on occupants of the room.
• Please install an air filter purchased on site.
Install the unit so that there are no air bypasses other than
the filter.
[About electric work]
• A qualification is required for carrying out any electric work
or D-type grounding work. Consult with your dealer and do
not carry out any electric work by yourself.
• Use dedicated circuit only for the air conditioner.
[Electric wires]
• The air conditioner should be equipped with dedicated elec-
tric wires.
• The indoor fan motor and the outdoor unit should be
equipped with dedicated electric wires respectively.
[Operation noise]
• Select a location as follows for installation.
a. where sufficient load of the air conditioner is secured and
the operation noise and vibration do not expand
b. where the heated air from the air outlet of the outdoor unit
and operation noise do not give any trouble to the neigh-
borhood
• Is there any obstacle around the air outlet of the outdoor
unit?
• Consult with your dealer should any abnormal sound be
heard when using the unit.
• The unit is not for use where silent operation is required.
Install the unit in a place such as a utility room where noise
is not a problem, and connect it with a duct.
[Position of on-site air inlet]
• Consider the air inlet and its surroundings and prevent
intake of soot and dust. Greasy dirt within the air condi-
tioner may cause reduced performance and water leakage.
[Drainage piping]
• After installation of drainage piping, please confirm if normal
drainage is possible. If bad drainage occurs during cooling
operation, it is possible that there is rubbish, dust in the
drainage pipes and that the indoor unit is leaking. In that
case, please stop running and contact the dealer.
[Air filter]
• The air filter is provided on site and only a filter compatible
with the local usage environment should be installed.
• Please avoid any gap with the air inlet during installation.
