SELECTION OF LOCATION
This unit does not have specifications for outdoor installation. The
unit must be installed indoors (example: machine room, …).
Paying attention to the conditions mentioned below, select the place for
installation with a prior approval of customer.
1.
The foundation is strong enough to support the weight of the unit and
the floor is flat to prevent vibration and noise generation.
2.
Consider the space required for refrigerant piping work when install-
ing. Refer to [Necessary Space].
3.
There is no danger of fire due to leakage of inflammable gas.
4.
The piping length between the outside unit and the indoor unit may
not exceed the allowable piping length. “
5.
Locations where the noise of the unit operating will not disturb
nearby houses, etc.
6.
Locations with airflow and ventilation holes capable of dissipating
heat from the machine and where the ambient temperature around
the outside unit is between 35 and 95 °F and the humidity does not
exceed 80%.
[Necessary Space]
When installing, secure the space mentioned below without fail.
(Refer to figure 2)
1.
In case of a single installation [inch.]
2.
In case of series installations [inch.]

10.
Secure spaces in the front, back and top sides as same as
the case of single installation.
DANGER
•
Do not install unit in an area where flammable materials are
present due to risk of explosion resulting in serious injury or death.
•
Refrigerant is heavier than air and replaces oxygen. A massive leak
could lead to oxygen depletion, especially in basements, and an as-
phyxiation hazard could occur leading to serious injury or death. Re-
fer to the chapter “Caution for refrigerant leaks”.
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 dis-
tances of 10 ft or more and use conduit tubes for power and trans-
mission lines.
2.
Water quality
Water containing high level of foreign materials may cause the
corrosion of heat exchanger and piping or scale accumulation.
Use water satisfying “7-4 Water quality”.
3.
Cooling tower
Use a closed type cooling tower without fail. (Open type tower
cannot be used.)
4.
Strainer
Install the strainer (accessory) without fail at the inlet of water pip-
ing. (If sands, wastes, rust particles, etc. are mixed in the water cir-
culation system, damage to the plate type heat exchanger may be
caused by the corrosion of metal materials and clogging of the
heat exchanger.)
WARNING
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 refrigerant
to leak.
• Locations where equipment that produces electromagnetic waves is
found.
The electromagnetic waves may cause the control system to mal-
function, preventing normal operation.

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.
In order to prevent any damage to the unit during installation, use
slings (cloth) or patch plates and lift the unit referring to figure 4.
4.
Lift the unit preferably with a crane and 2 belts of at least 27 ft 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.
Be sure use the standard supplied accessories and dedicated parts
as installation parts.
(Refer to figure 4)

Patch plates or clothes
2.
Belt sling
NOTE
•
Use belt sling of 13/16” width or less which adequately bears the
weight of the product.
5.
UNPACKING AND PLACING THE UNIT
• Make sure the area around the machine drains properly by setting up
drainage grooves around the foundation.
• 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”.
• Fix 4 foundation bolts.
• Support the unit with the foundation which is
larger than the hatched area shown in figure 5.

CAUTION
•
When installing the unit closely contacting the wall for any
unavoidable reason, arrange so that no vibration from the unit may
be transmitted to the wall surface by insulating the vibration using
cushions, etc.
