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.

NEW

Cassette type:

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. In addition, it can be compatible with the old remote controllers.

Low ambient temperature cooling function (optional) Equipped with high/low pressure protection switch

The indoor units of AU282AHBEA and AU28NAHBEA are the same.

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.

It shall use the vacuum pump of (lower than -755mmHg)high vacuum degree and large air

discharging (over 40l/min). The vacuumizing time depends on the length of the connecting pipe, generally is 1~2 hours. When vacuumizing, it shall be confirmed both gas and liquid side valves are closed. If after 2 hours vacuumizing, it cannot reach the vacuum degree below -755mmHg, it can be vacuumized for other 1 hour. If after 3 hours vacuumizing, it still cannot reach the vacuum degree below -755mmHg, check if there is any leaking point and repair the them. If after over 2 hours vacuumizing, the vacuum degree is below -755mmHg, close the V

L and VH on the meter separator and stop vacuumizing. 1 hour later to confirm if the vacuum degree changes. If changes, it indicates there is leaking point in the system. Check the leaking point and repair. After finishing the above vacuumizing, change the vacuum pump into refrigerant pump to charge the refrigerant.

Use vacuum pump to perform vacuumizing. It is strictly forbidden to use the refrigerant to remove the air inside the system. After air tightness test and discharging all the nitrogen, connect the vacuum pump as the following figure shown.

When the total length (L) of the two indoor units' connecting pipe is less than 5m, it is unnecessary to charge additional refrigerant. If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter. That is: Refrigerant charging amount = (L-5) x M (g)

For AU242AHBEA, M=65

Only in COOLING operation can charge the additional refrigerant. When charging, the refrigerant shall be charged from the charging nozzle of low pressure vavle. Be carefull when charging refrigerant, do not let the air mix into the system,and must charge the additional refrigerant in liquid condition.

Insert water supply hose for 20 mm ~ 30 mm to supply water. (Insert hose facing toward bottom.)

Pour water into a convex joint.

When constructing drain piping for several units, position the common pipe about 100 mm below the drain outlet of each unit as shown in the sketch. Use VP-30(11/4") or thicker pipe for this purpose. Be sure to provide heat insulation to hard PVC pipes of indoor placement. Do not ever provide an air vent. The height of the drain head can be elevated up to a point 500 mm above the ceiling, and when an obstacle exists in the ceiling space, elevate the piping to avoid the obstacle using an elbow or corresponding gadget. When doing this, if the stretch for the needed height is higher than 500 mm, the back-flow quantity of drain at the event of interruption of the operation gets too much and it may cause overflow at the drain pan. Therefore, make the height of the drain pipe within the distance given in the sketch below. Avoid positioning the drain piping outlet at a place where generation of odor may be stimulated. Do not lead the drain piping direct into a sewer from where sulfur gas

Drainage Test

extended, it also can not be imported from top) Place ensures enough space for maintenance. The pipe length between indoor and outdoor unit is in the permitted limit (referring to outdoor unit

installation part). The indoor unit, outdoor unit, electric wire and connection wire is at least 1m away from television

and radio. This is to avoid the image disturbance and noise caused by the above-mentioned home appliance. (Even if 1m away, if the electromagnetic wave is too strong, it can also cause noise.)

(2) The height of ceiling

The indoor unit can install on the ceiling, which height is no more than 3m.

(3) Install and use the hoisting screw. Check if the installation place can bear the weight of unit assembly.

If not certain, strengthen it before install the unit.

(2) If necessary, cut the opening installation and checking needed on the ceiling. (If has ceiling)

Before installation, finish the preparation work of all the pipes (refrigerant, drainage) and wire (wire controller connection wire, indoor and outdoor unit connection wire) of indoor unit, so that after installation, they can be immediately connected with outdoor unit.

Cut the opening on the ceiling. Maybe it needs to strengthen the ceiling to keep the ceiling even and flat and prevent the ceiling from vibration. For details, please consult to the builder.

(Use M10 screw bolt) In order to bear the weight of the unit, for existed

ceiling, using foundation screw bolt, for new ceiling, using burying embedded screw bolt, burying screw bolt or spot supplied other parts.

Before going on installation, adjust the gaps with ceiling.

The stiff PVC pipe put indoor side should be heat insulated.

(f)

Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain hose directly into drainage, where the gas with sulfur may be generated.

Backwater bend Because the drain spout is at the position, which negative pressure may occur. So with the rise of water

level in the drain pan, water leakage may occur. In order to prevent water leakage, we designed a backwater bend.

The structure of backwater bend should be able to be cleaned. As the below figure shown, use T type joint. The backwater bend is set near the air conditioner.

As figure shown, set a backwater bend in the middle of drain hose.

8. The attentive matters in installation of air suction and discharging duct

Recommend to use anti-frost and sound-absorbing duct. (locally bought) The duct installation work should be finished before the fitment of ceiling.

The duct must be heat insulated. The specific air-discharging outlet should be installed at

the place where the airflow can be reasonably distributed. The surface should leave a checking meatus for checking

and maintenance.

9. The examples of improper installation

Do not use air in duct and take the ceiling inner side instead. The result is because of the irregular outer air mass, strong wind and sunshine, the humidity is increased.

There may be water drop on the outside of duct. For cement and other new constructions, even if not taking ceiling inner side as duct, the humidity will also be so high. At this time, use glass fiber to perform heat preservation to the whole. (use iron net to bind the glass fiber)

Affected by the capacity of air discharging fan, the strong wind in the outer duct and wind direction, when unit air sending volume exceeds the limit, the discharged water of heat exchanger will overflow, leading to water leakage.

Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted.

10. The operation method of fan controller

It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment). The air volume set should be in the operation air volume range. Figure I shows the position of fan controller in the electric box and operation method.

After finishing the electric work, perform test run. According to the main points in Figure II making the chosen switch No. accordant. And confirm if it reaches the needed air volume.

Note:

1) When operating the fan controller, it is possible to touch the electric charging part, so do cut off the power supply.

2) Do not set the dial at the position less than 1.

3) The figure circled in Figure II indicate the capacity number of fan controller. The non-listed capacity number may exceed the permitted operation capacity range, so it is impossible to operate.

4) When delivering from factory, the capacity number of fan controller is set at ìNo.5î.

Rotate this switch

(capacity number setting: No. 1 ~ No. 8)

Once the fan controller has trouble, this linker can perform emergency assistant control. When this linker is connected to the linker from the PCB, it can operate with total load.

When this linker is connected to the linker from the PCB, through the fan speed adjustment panel to adjust speed.

11. Refrigerant pipe

[The air side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause water leakage.]

The outdoor unit has been charged with refrigerant. When connect the pipe to the unit or dismantling the pipe from the unit, please follow the figure shown,

use spanner and torque spanner together. When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use

hand to twist 3-4 rings, then fasten with spanner. Referring to Table I to confirm the fasten torque. (too tight may damage nut leading to leakage)

Check if the connection pipe leaks, then do heat insulation treatment, as below figure shown. Only use seal cushion to bind the joint part of air pipe and heat insulation parts.
