Installation Si39-303
56 General Information
3.2.12 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.
•
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 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 explosion.
