SELECTION OF LOCATION
This unit, both indoor and outdoor, is suitable for instal-
lation in a commercial and light industrial environment. If
installed as a household appliance it could cause electro-
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
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.
No limit to wall height
3. 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
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 on Page 49.
5. Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
INSPECTING AND HANDLING THE UNIT
At delivery, the package should be checked and any dam-
age should be reported immediately to the carrier claims
When handling the unit, take into account the following:
Installation of Outdoor Units
6. Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind
will disturb the operation of the unit. If necessary, use a
windscreen to block the wind.
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. Refer to Section 9. Caution
for Refrigerant Leaks.
An inverter air conditioner may cause electronic noise
generated from AM broadcasting. Examine where to in-
stall the main air conditioner and electric wires, keeping
proper distances away from stereo equipment, personal
Refer to figure 2.
Branch switch, overcurrent breaker
COOL / HEAT selector
personal computer or radio
If the electric wave of AM broadcasting is particularly
weak, keep distances of 10 ft. or more and use conduit
tubes for power and transmission lines. In heavy snowfall
areas, select an installation site where snow will not affect
operation of the unit.
Do not install in the following locations.
Locations such as kitchens which contain a lot of min-
eral oil or steam in the atmosphere or where oil may
splatter on the unit.
Resin parts may deteriorate, causing the unit to fall or
Locations where sulfurous acids and other corrosive
gases may be present in the atmosphere.
Copper piping and soldered joints may corrode, caus-
ing refrigerant to leak.
Locations where equipment that produces electromag-
netic waves is found.
The electromagnetic waves may cause the control sys-
tem to malfunction, preventing normal operation.
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor
Choose the path along which the unit is to be brought in
ahead of time.
If a forklift is to be used, pass the forklift arms through the
large openings on the bottom of the unit.
