c)Brief introduction of the series:
Convertible type:
AC242ACBEA AC28NACBEA
(1).Ceiling convertible,flexible installation,convenient
maintenance,saving the users' expenditures
(2)Adopting single-phase & three-phase power supply,applicable for
household and commercial usage
(3).Dual air outlet design,floor air blowing,accelerating the indoor air
circulation, quick temperature adjustment
(4).Long-distance air blowing,large power,large cooling/heating
ratio
(5).Intelligent remote control,convenient and flexible control
(6).Super-slim indoor unit design,luxury and nice-looking,saving
space,harmonious and unitive with the indoor environment
(7).Adopting screw-fastening for the air inlet grill,firmly
fixed;adopting slipway insert-lock fastening method for the
filter screen,convenient cleaning or replacing the filter screen
without opening the air inlet grill.
(8).Group control,units up to 128 sets can be controlled .
Duct type :
AD242AMBHA AD242AHBEA AD28NAMBEA
Totally concealed machine body
All the machine body is to be installed inside the ceiling, having no effect on the
beauty of the room and without taking any room space.
Air intake via the rear air intake duct
This new design has changed the former unique pattern of air intake, and a larger
distance between air intake and air return cycles as well as better air quality can be
achieved.
Flexible and easier installation
The machine body is to be installed in a totally concealed way,its fan system has
a longer distance coverage so as to supply its airflow to several rooms, and the
indoor unit may be installed inside the ceiling of a room or corridor. The
installation is simple and flexible, and there is no need to have specified personnel
for management, thus cutting down the expenses; the machine is lighter and
smaller, and convenient for installation, it takes an extremely small building space,
thus lower the construction cost; the indoor unit is to be concealed inside the
ceiling, and hence the usable space can be saved and the room decoration will
not be affected.

AB242ACBEA AB28NACBEA
Products characteristic:
Completely invisible machine body:
The whole machine body is completely concealed inside the ceiling. Due to its compact size it neither
breaks the harmonization of indoor decoration nor occupies the indoor spaces. The stylish look of air
conditioner allows it to blend right into ceiling.
Superbly efficient healthy filter:
Superbly efficient antibiotic materials are utilized and can prevent germs from
breeding efficiently .
Flexible and easy installation
Slim design with machine body, completely ceiling concealing and portable shape, all make it greatly
easier to install. Moreover, it occupies least constructional spaces, which help to reduce constructional
cost prices. It also features a specific drainage system with up to 600mm lift , which allows reducing
installation spaces and ensures to drain smoothly. Thanks to its "smudge-free"
mobile outlet grill,
the ceiling can be protected from pollution effectively and allow the airflow to fit people's
comfortable need much more
.
Compensation function of power failure:
When meeting a power failure during running, no matter how long it will be, once the power is
restored, air conditioner will automatic restart with the previous status.
Safety and reliable control due to various signal controls
1 Inputting with press buttons on the panel
2 Inputting with temperature sensors (indoor ambient temperature sensors, indoor coil pipe
temperature sensors,
3 Piping pressure signals
4 Compressor current signals
5 Testing signals
6 System time-shorten signal
7 Water overflowing signal
8 Communication signals between indoor unit and front plate or between indoor unit and outdoor
unit .
Silent design
The use of radial outward flow turbine fan produces larger cyde airflow volume and acts to
significantly decrease operating noise.
When using remote-controlling mode, it is comfortable and convenient to operate.
Advanced wire-controller and convenient remote-controller
The new wired controller can connect with 16 indoor units without any device such as detectors.
The new remote controller can be used for single unit or muti-free unit, or H-MRV,very convenient.
Cassette type:
In addition, it can be compatible with the old remote controllers.
Low ambient temperature cooling function (optional)
Equipped with high/low pressure protection switch

WARNING
CAUTION
WARNING
CAUTION
This system should be applied to places of office, restaurant, residence and the like. Appliaction to inferior
environment such as engineering shop could cause equipment malfunction.
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.
When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned
countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration.
In regards to preparing this countermeasure, consult with the company from which you purchased the equipment,
and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold
concentration does occur,there is the danger of a resultant oxygen deficiency accident.
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient,
injury can result from a falling of the unit.
Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and
hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit.
For electrical work, please see that a licensed electrician executes the work while following the safety standards
related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive
use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and
fires.
Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to
the terminal connection part, through properly securing it. Improper connection or securing can result in heat
generation or fire.
Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can
also result in heat generation or fire.
WARNING
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 (customer) of this equipment, based on the owner's
manual.
Moreover, ask the customer to keep this sheet together with the owner's manual.
Please read these "Safety Precautions" first then accurately execute the installation work.
Though the precautionary points indicated herein are divided under two headings, and
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 section. However, there is also a
possibility of serious consequences in relationship to the points listed in the section as well.

SAFETY PRECAUTIONS
3 SAFETY PRECAUTIONS
When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated
refrigerant (please see nameplate) within the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
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 refigerant leakage.
The position of indoor unit must be above the floor 2.5m.
WARNING
Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightening rod or a telephone
ground wire.
Improper placement of ground wires can result in electric shock.
The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not
installing an earth leakage breaker may result in electric shock.
Do not install the unit where there is a concern about leakage of combustible gas.
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.
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.
