4. Character of Products
1) The length of horizontal refrigerant pipe can reach 70m,the total pipe length can reach
100m, the height difference between indoors unit and outdoor unit can reach 50m, the
height difference between indoor units can reach 10m.
2) 1000m super far distance communication between indoor and outdoor units, convenient
control and easy to enlarge the scale of units assembly.
3) Indoor unit can be controlled separately.
4) Equipped with computer-checking interface, conveniently for service work.
5) Far distance sending of refrigerant, and distribute refrigerant intelligently and reasonably
according to the needs of each room, high efficient and energy saving.
6) Display of automatic test of trouble.
7) Healthy negative ion generation function can refresh the air and excite the oxygen,it is optional.
8) The AE and AS indoor units move the indoor electronic expansion valve out to
MP3 (electronic expansion valve box), completely avoid the flow sound of EEV,
extremely lower noise, and realize super-silence running in deed.
9) The ceiling concealed models all have return air box, it will be set back return air
when out of factory. When installation, bottom plate 2 can be removed and installed
on the back, consequently, return air mode has been ransferred to down return
air.
10) In order to remain the best running state of indoor unit, control the refrigerant flow
by MP3 (MP2), so as to realize energy saving for every unit and the most
comfortable operation.
11) The units except for convertible model are all wired controller and remote controller
models.If you want a wired control unit or a remote control unit, please inform us ahead of
schedule.
The unit with remote controller is matched with receive display.
The unit with wired controller equipped with wired controller, can make remote operation on
wired controller with remote controller such as YR-H71, but the remote controller is
additionally purchased.

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.

SAFETY PRECAUTIONS
Note : (1). Fix the parts with screws
(2).Don't intake the strong wind directly
to the outlet air-flow hole.
(3).A one meter distance should be
kept from the unit top
(4).Don't block the surroundings of the unit with sundries

MP3（MP2）installation procedure：
1、Installation of MP3（MP2）can be used for CEILING CONCEALED MODEL
A、Piping connection
a、When connecting with indoor unit，refrigerant pipe and the connection wire must be
corresponding with the code（A、B、C…） on the device.
NOTE: When using two or more than two MP3 devices (need two or more than two
MP3 devices on connecting more than three indoor units), MUST mark definitely
Room code of connected indoor unit on the MP3 label, so as to air conditioner
maintain conveniently.
b 、 When connecting indoor unit, firstly please weld MP3 with the corresponding
contribution pipe in the accessories table, then connect MP3 with corresponding indoor
connection pipe.
c、MP3 can only be connected with liquid pipe of the unit, the gas pipe connection is the
same as the old ceiling concealed model.
B、MP3(MP2) device installation position
a、MP3(MP2) device should be counted on the vertical wall, maintenance cover panel
must be to the outer, and open a maintenance door over 600mm out of the panel.
b、Indoor distribution pipe must be fetched out from up of MP3 to any direction.
c、Lean must be in the range of ±5°.
C、Wiring connection:
a、Power wiring、communication wiring of the same indoor unit must correspond with its
connection pipe、electronic expansion valve (refer to the wiring diagram on the indoor
electric box cover and MP3).
b、After wiring connection, the wiring must be fixed firmly with wire clip.
2、MP3(MP2) refrigerant circuit can be used for ceiling concealed model (only show
out liquid pipe connection)
Note: Cutoff the pipe of standard
accessories according to indoor
distribute pipe diameter, then connect it
with MP3
