by the general public must be installed in the
safety area to prevent others from getting
close to these electric appliances.
Both indoor and outdoor units are suitable for
the installation of commercial and light
industrial environment.
An
excessively
high
refrigerant in an enclosed area can lead to
anoxia (oxygen deficiency).
NOTE
This is a class A product. This product may
cause radio interference in the home
environment. The user may need to take the
necessary measures if such a situation does
arise.
The unit described in this manual may cause
electronic noise generated by radio
frequency energy. The unit conforms to the
design specifications and provides
reasonable protection to prevent such
interference. However, there is no guarantee
that there will be no interference during a
specific installation process.
Therefore, it is suggested that you install the
units and wires at an appropriate distance
from devices like sound equipment and
personal computers.
Do take into considerations adverse environmental
conditions such as strong winds, typhoons or
earthquakes as an improper installation may cause
the unit to overturn.
Take precautions to make sure the water will not
damage the installation space and environment in
the event of a water leakage.
If the unit is installed in a small room, refer to
section 4.2.3 "Caution for refrigerant leaks" to make
sure the refrigerant concentration does not exceed
the permissible safety limit when there is a
refrigerant leak.
Make sure the air inlet of the unit is not directed at
the main wind direction. Incoming wind will disrupt
the operations of the unit. If necessary, use a
deflector as an air baffle.
Add water drain piping on the base so that the
condensed water will not damage the unit, and
prevent the accumulation of water to form pits when
the works are in progress.
4.2.2 Site requirements for installation of
outdoor unit in cold regions
NOTE
Snow protection facilities must be installed in
areas with snowfall. Refer to the following
figure, (malfunctions are more common when
there is insufficient snow protection facilities).
In order to protect the unit from accumulated
snow, increase the height of the rack, and
install a snow shield at the air inlets and
outlets.
Do not obstruct the air flow of the unit when
you install the snow shield.
