Weather Related Precautions; Selecting A Location In Cold Climates - Daikin VRV IV Manuel D'installation

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 equip-
ment, personal computers, etc.
Particularly for locations with weak reception, ensure there is a dis-
tance of at least 10 ft. (3 m) for indoor remote controllers, place power
wiring and transmission wiring in conduits, and ground the conduits.
• The refrigerant R410A itself is nontoxic, non-flammable 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 18. Caution
for refrigerant leaks on page 44.
• Do not install in the following locations:
- 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 a mineral oil mist, spray or vapor may be pres-
ent in the atmosphere. Plastic parts may deteriorate and fall off or
cause water leakage.
- Locations where equipment that produces electromagnetic
waves is found. The electromagnetic waves may cause the con-
trol 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, caus-
ing an explosion.
• When installing, take strong winds, hurricanes or earthquakes into
account, improper installation may result in the unit turning over.

4 .2 . Weather related precautions

• Be sure that the air inlet of the unit is not positioned towards the
main wind direction. Frontal wind will disturb the operation of the
unit. If necessary, use a screen to block the wind.
• Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in the
construction.
• When installing in areas where air contains high levels of salt such
as near the ocean; Contact your Daikin sales representative for
additional precautions.

4 .3 . Selecting a location in cold climates

NOTE
• When operating the unit in a low outdoor ambient temperature, be
sure to follow the instructions described below.
• The following images are for reference only. For more details con-
tact your local dealer.

To prevent exposure to wind and snow, install a baffle plates on the air
side of the outdoor unit (see 5 .2 . Service space for space requirement):
1 Baffle plates
In heavy snowfall areas it is very important to select an installation
site where the snow will not affect the unit. Additionally, installation of
a snow guard is recommended. When installing the unit in a location
where there is heavy snowfall, remove the coil guards to prevent snow
from accumulating on the fins.
If lateral snowfall is possible, make sure that the heat exchanger coil
is not affected by the snow (if necessary construct a lateral canopy).
Install the outdoor unit so that the bottom frame is at least 19-11/16 in.
(500 mm) above predicted snowfall levels.
1 Construct a large canopy.
2 Construct a pedestal.
NOTE
When operating the unit in a low outdoor ambient temperature with
high humidity conditions, make sure to take precautions to keep the
drainholes of the unit free.
