Commercial Air Conditioner
Model: AU182AFERA
AD182AMERA, AS182AVERA
Please read these "Safety Precautions" first then accurately execute the installation work.
The precautionary points indicated herein are divided under two headings:
WARNING and CAUTION those points which are related to the strong possibility of an
installation done in error resulting in death or serious injury are listed in the WARNING
section. However, there is also a possibility of serious consequences in relationship to the
points listed in the CAUTION section as well.
In either case, important safety related information is indicated, so by all means, properly
observe all that is mentioned.
After completing the installation, along with confirming that no abnormalities were seen
from the operation tests, please explain operating methods as well as maintenance methods to
the user of this equipment, based on the owner's manual.
Moreover, ask the customer to keep this sheet together with the owner's manual.
WARNING
Please entrust installation to either the company which sold you the equipment or to a
professional contractor. Defects from improper installations can be the cause of water leakage
electric shocks and fires.
Execute the installation accurately, based on following the installation manual. Again improper
installations can result in water leakage, electric shocks and fires.
Please install your air conditioner on a wall or any place which can holder the weight of the
air conditioner. And it cannot be installed on a non-professional metal structure (such as a
burglary-resisting net). Otherwise injury would occur due to a falling of the unit.
Execute the prescribed installation construction to prepare for earthquakes and the strong airs
of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent
falling over of the unit.
Wiring shall be done with the specified cable and the connection shall be firm and reliable.
And the terminal connector shall be fixed firmly and reliably not to let external force exercise
on the cables. Any improper connection or fixing would cause heat, fire, and other accidents.
Wiring shall be done in a correct shape not to make any section rise upward, and accurately
install the air conditioner. The cable shall not be clamped by the lid or outer plate. Any
improper installation would lead to fire, heat, or other accidents.
When setting up or moving the location of the air conditioner, do not mix air etc, or anything
other than the designated refrigerant (R407C) within the refrigeration cycle, for such mixing
would result in rupture and injury caused by abnormal high pressure.
Always use accessory parts and authorized parts for installation construction. Using parts not
authorized by this company can result in water leakage, electric shock, fire and refrigerant
leakage.
The drain pipe must not be placed or connected into the sewage tank where harmful gas such
as sulphurous gas and etc would exist, otherwise the harmful gas would enter the room.
During installation, if the refrigerant is leaked, please immediately take measures of
ventilation, otherwise a harmful gas would be generated whenever the refrigerant meets fire.
After installation, please ensure that the refrigerant is not leaked, because the leakage of
refrigerant would produce a harmful gas if it meets fire or heating stoves.
Don't install the air conditioner where a flammable gas would be probably produced,
otherwise in case the flammable gas is leaked and exists around the unit, fire would be
caused.
For the drain pipe, follow the installation manual to insure that it allows proper drainage and
thermally insulate it to prevent condensation. Inadequate plumbing can result in water
leakage and water damage to interior items.
The refrigerant gas pipe and liquid pipe shall all be thermally insulated to preserve the
temperature. Any improper insulation would make the unit moist and the water would drop
onto the floor or wet the indoor items.
