Installation Manual
3. 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 below and choose one of both possibilities)
3. 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 discharged 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 operation of the unit. If necessary, use a windscreen to
block the wind.
Caution
1. An inverter air conditioner may cause electronic noise generated from AM broadcasting.
Examine where to install the main air conditioner 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 3m 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.
3. The refrigerant R410A itself is nontoxic, nonflammable and is 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”.
4. 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.
