SELECTION OF LOCATION
This unit, both indoor and outdoor, is suitable for installation in
a commercial and light industrial environment. If installed as
a household appliance it could cause electromagnetic
interference.
The VRV OUTDOOR units should be installed in a location
that meets the following requirements:
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. The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available.
Refer to Figure 1, and choose a Pattern.

3. Ensure that water cannot cause any damage to the location
by dripping out of the unit, such as from a blocked drain
pipe.
4. The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length.See Section 6.3
Example of Connection.
5. Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
anyone.
6. Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind
disturbs the operation of the unit. If necessary, use a wind-
screen to block the wind.
DANGER
Do not install unit in an area where flammable materials
are present due to risk of explosion resulting in serious in-
jury or death.
Refrigerant is heavier than air and replaces oxygen. A
massive leak could lead to oxygen depletion, especially in
basements, and an asphyxiation hazard could occur lead-
ing to serious injury or death.
NOTE
1. An inverter air conditioner may cause electronic noise
generated from AM broadcasting. Examine where to
install the main air conditioner and electric wires, keep-
ing proper distances away from stereo equipment, per-
sonal computers, and other electronic devices.

If the electric wave of AM broadcasting is particularly
strong , keep distances of 10 ft. or more and use con-
duit 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
Do not install in the following locations:
Kitchens containing 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.
Where sulfurous acids and other corrosive gases may be
present in the atmosphere.
Copper piping and soldered joints may corrode, causing
refrigerant to leak.
Where equipment produces electromagnetic waves.
The electromagnetic waves may cause the control system
to malfunction, preventing normal operation.

INSPECTING AND HANDLING THE
UNIT
At delivery, the package should be checked and any dam-
age 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 it to be used, pass the forklift arms through the
large openings on the bottom of the unit.
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. 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.
