In places with weak reception, keep distances of 3 m
or more to avoid electromagnetic disturbance of other
equipment and use conduit tubes for power and
transmission lines.
The refrigerant R410A itself is non-toxic,
•
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
(see "19. Caution for refrigerant leaks").
Do not install in the following locations:
•
- Locations where sulphurous 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 vapour
may be present 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 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.
When installing, take strong winds, typhoons or
•
earthquakes into account, improper installation may
result in the unit turning over.

6.2 Weather related precautions

Select a place where the rain can be avoided as
•
much as possible.
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.
Do not install the unit in areas where the air contains
•
high levels of salt such as that near the ocean.

6.3 Selecting a location in cold climates

NOTICE
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 contact your local dealer.
To minimize exposure to wind and snow, install a baffle plate
on the air side of the outdoor unit (see "7.2 Service space").
1 Baffle plate
In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit.
When installing the unit in a location where there is heavy
snowfall, remove the coil guards to prevent snow from
accumulating on the fins, and install the snow/wind hood
kit (optional accessory) or/and a top canopy (field supply).
When installing a canopy, be careful not to create a short
circuit and to leave enough space between the canopy
and top of the unit for proper air discharge.
If lateral snowfall is possible, make sure that the heat
exchanger coil is not affected by the snow (if necessary
construct a lateral canopy).

2 Construct a pedestal.
Install the unit high enough from the ground to
prevent burying in snow.
NOTICE
When operating the unit in a low outdoor
ambient temperature with high humidity
conditions, make sure to take precautions to
keep the drain holes of the unit free.
