ENGLISH
−
Do not install the unit in places often used as a work space.
In case of construction work (e.g. grinding etc.) where a lot of
dust is created, the unit must be covered.
−
Do not place any object or equipment on top of the unit (top plate).
−
Do not climb, sit or stand on top of the unit.
−
Be sure that sufficient precautions are taken in case of refrige
-
rant leakage according to relevant local laws and regulations.
−
Don’t install the unit near the sea or where there is corrosion
gas.
When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the unit's air
outlet causes a short circuit (suction of discharge air), and this
may have the following consequences:
−
Deterioration of the operational capacity.
−
Frequent frost acceleration in heating operation.
−
Disruption of operation due to rise of high pressure.
−
When a strong wind blows continuously on the front of the
unit, the fan can start rotating very fast until it breaks. In nor-
mal condition,refer to the figures below for installation of the
unit:
A
Unit
A(mm)
4~6kW
≥300
8~16kW
≥300
In case of strong wind and the wind direction can be foreseen,refer to
the figures below for installation of the unit(any one is OK):
Turn the air outlet side toward the building's wall, fence or screen.
B
Unit
B(mm)
4~6kW
≥1000
8~16kW
≥1500
Make sure there is enough room to do the installation.
Set the outlet side at a right angle to the direction of the wind.
Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
If water does not easily drain from the unit, mount the unit on a
foundation of concrete blocks, etc. (the height of the foundation
should be about 100 mm.
If you install the unit on a frame, please install a waterproof plate
(about 100 mm) on the underside of the unit to prevent water
from coming in from the low side.
When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as pos-
sible.
6.1 Selecting a location in cold climates
Refer to "Handling" in section “4 Before installation”
NOTE
When operating the unit in cold climates, be sure to follow the in-
structions described below.
To prevent exposure to wind, install the unit with its suction side
facing the wall.
Never install the unit at a site where the suction side may be
exposed directly to wind.
To prevent exposure to wind, install a baffle plate on the air di
-
scharge side of the unit.
In heavy snowfall areas, it is very important to select an installa-
tion site where the snow will not affect the unit. If lateral snowfall
is possible, make sure that the heat exchanger coil is not af-
fected by the snow (if necessary construct a lateral canopy).
①
②
1 Construct a large canopy.
2
Construct a pedestal.
Install the unit high enough off the ground to prevent it from being
buried in snow.
6.2 Selecting a location in hot climates
As the outdoor temperature is measured via the outdoor unit air ther-
mistor, make sure to install the outdoor unit in the shade or a canopy
should be constructed to avoild direct sunlight, so that it is not influen
-
ced by the sun’s heat, otherwise protection may be possible to the unit.
If you install the unit on a building frame, please in-
stall a waterproof tray (field supply) (about 100mm,
on the underside of the unit) in order to avoid drain
water dripping. (See the picture in the right).
