The space around the unit is adequate for servicing and the mini-
mum space for air inlet and air outlet is available.
(refer to figure 1 and choose one of both possibilities)

There is no danger of fire due to leakage of inflammable gas.
4.
Ensure that water cannot cause any damage to the location in case
it drips out the unit (e.g. in case of a blocked drain pipe).
5.
The piping length between the outdoor unit and the indoor unit may not
exceed the allowable piping length. (see “Example of connection”)
6.
Select the location of the unit in such a way that neither the dis-
charged air nor the sound generated by the unit disturb anyone.
7.
Make sure that the air inlet and outlet of the unit are not positioned
towards the main wind direction. Frontal wind will disturb the opera-
tion of the unit. If necessary, use a windscreen to block the wind.
NOTE
1.
An inverter air conditioner may cause electronic noise generated
from AM broadcasting. Examine where to install the main air con-
ditioner and electric wires, keeping proper distances away from
stereo equipment, personal computers, etc.

If the electric wave of AM broadcasting is particularly weak,
keep distances of 10ft. or more and use conduit tubes for power
and transmission lines.
2.
In heavy snowfall areas, select an installation site where snow will
not affect operation of the unit.
WARNING
1.
The refrigerant R410A itself is nontoxic, nonflammable and safe.
If the refrigerant should leak however, its concentration may
exceed the allowable limit depending on room size. Due to this it
could be necessary to take measures against leakage. Refer to
the chapter “Caution for refrigerant leaks”.
2.
Do not install in the following locations.
•
Locations such as kitchens which contain a lot of mineral oil or
steam in the atmosphere or where oil may splatter on the unit.
Resin parts may deteriorate, causing the unit to fall or leak.
•
Locations where sulfurous acids and other corrosive gases may
be present in the atmosphere.
Copper piping and soldered joints may corrode, causing refrig-
erant to leak.
•
Locations where equipment that produces electromagnetic
waves is found.
The electromagnetic waves may cause the control system to
malfunction, preventing normal operation.
•
Locations where flammable gases may leak, where thinner,
gasoline, and other volatile substances are handled, or where
carbon dust and other incendiary substances are found in the
atmosphere.
Leaked gas may accumulate around the unit, causing an explo-
sion.
4. INSPECTING AND HANDLING THE UNIT
At delivery, the package should be checked and any damage
should be reported immediately to the carrier claims agent.
When handling the unit, take into account the following:
1.
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2.
Choose the path along which the unit is to be brought in ahead of
time.
3.
If a forklift is to be used, pass the forklift arms through the large open-
ings on the bottom of the unit.
4.
Lift the unit preferably with a crane and 2 belts of at least 27ft. long.
5.
When lifting the unit with a crane, always use protectors to prevent
belt damage and pay attention to the position of the unit’s center of
gravity.
6.
After installation, remove the transport clasps attached to the large
openings.
7.
Bring the unit as close to its final installation position in its original
package to prevent damage during transport.

5. UNPACKING AND PLACING THE UNIT
•
Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise.
•
Secure the unit to its base using foundation bolts. (Use four commer-
cially available M12-type foundation bolts, nuts, and washers.)
•
The foundation bolts should be inserted 13/16”.
•
Make sure the base under the unit extended
more than 30-1/8” behind the unit.
•
The height of the base should be at least 5-7/8”
from the floor.
•
The unit must be installed on a solid longitudinal foundation (steel-
beam frame or concrete) as indicated in figure 4.

DO NOT USE STANDS TO SUPPORT THE CORNERS
(Refer to figure 5)

Do not use stands to support four corners.
2.

NOTE
1.
Prepare a water drainage channel around the foundation to
condensate waste water from around the unit.
2.
If the unit is to be installed on a roof, check the strength of the roof
and its drainage facilities first.
3.
If the unit is to be installed on a frame, install the waterproofing
board within a distance of 5-7/8” under the unit in order to pre-
vent infiltration of water coming from under the unit.
NOTE
•
When installing on a roof, make sure the roof floor is strong enough
and be sure to water-proof all work.
•
Make sure the area around the machine drains properly by setting
up drainage grooves around the foundation.
(Condensate water is sometimes discharged from the outdoor unit
when it is running.)
•
Block all gaps in the holes for passing out piping and wiring using
sealing material (locally procured).
(Small animals may enter the machine.)
