Duct type :

AD36NAMBEA+AU36NAIBEA AD42NAMBEA+AU42 NAIBEA

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:

AB36NACBEA+AU36NAIBEA AB42NACBEA+AU42NAIBE A

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

SAFETY PRECAUTIONS

3 SAFETY PRECAUTIONS

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

CAUTION

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.

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.

WARNING

CAUTION

WARNING

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.

Page 19

SAFETY PRECAUTIONS

WARNING

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.

CAUTION

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.

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.

Special air discharging outlet

Use screw bolt to fix

Air

Duct

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)

Maybe exceeding the unit operation limit (for example: when indoor dry bulb temperature is 35 C, wet bulb temperature 24 C), it may lead to overload of compressor.

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.

Air discharging fan

Improper example

10. The operation method of fan controller

Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted. 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 “No.5”.

(4) Cutoff protection against overload and overheat

During heating program, if the indoor blowing fan has been started and the compressor

has been running more than 2 minutes, and the temperature of indoor coil pipe (Ticp)

> 64

blowing fan has kept stop state for 45 seconds, then it will restore rotation; If Ticp > 67

and such temperature has last for 10 seconds, the compressor will stop running and

indoor blowing fan run according to conditions as it reaches setting temperature. When

Ticp < 58

compressor and outdoor blowing fan will restore normal running.

Cutoff protection for heating current

After 60 seconds from the compressor being started, if CT current exceeds I1 (9.2A) and

such case has kept 5 seconds, the outdoor blowing fan will stop. If 45 seconds has passed

after the outdoor blowing stops and the current of the compressor is less than I2 (7.5A), the

blowing fan will restore running. If CT current exceeds I3 (14.3A) and such case lasts for 3

seconds, the compressor and outdoor blowing fan will stop. The compressor will not restore

running until 3 minutes passes with CT current less than 12A.

(5) Cool wind prevention during heating program

At the first time entering heating program or after ending the latest frost removal, if the

temperature of indoor coil pipe (Ticp) < 28

compressor has been running for more than 4 minutes, the indoor blowing fan will run at

, the outdoor blowing fan will stops running; If Ticp ≤ 50 and the outdoor

, and the compressor has kept stop state over 3 minutes, then the

, the indoor blowing fan will stop running; If

Ticp < 38 , the indoor blowing fan will run at low speed; If Ticp > 38 or the

setting wind speed.

(6) Afterheat blowing during heating program

During heating program, the compressor will stop running (except overheat protection or

frost removal) while the indoor blowing fan will firstly run for 50 seconds at low speed then

stop.

(7) Frost removal control (applicable for cooling-heating type)

Starting conditions for frost removal:

A The indoor unit is in overload protection and outdoor blowing fan stops. The outdoor

blowing fan does not enter overheat mode in 10 minutes after it is restarted, the

compressor has run over 45 minutes totally while 20 minutes continuously, and the

temperature of indoor coil pipe is lower than 43 ;

B After the compressor continuously running for 20 minutes, the temperature of indoor

coil pipe falls 1 every 6 minutes and such case continuously appears three times,

and the temperature of indoor coil pipe is less than 40 , and 5 minutes have passed

after the compressor is restarted;

C The compressor has run totally over 3 hours while 20 minutes continuously, and the

temperature of indoor coil pipe is less than 40 ;

D The difference between room temperature and the one of indoor coil pipe is less than

16 and the compressor has totally run over 45 minutes while 20 minutes

continuously;

Frost removal will start if any one of the above conditions is satisfied.

Ending conditions for frost removal:

1 Time of frost removal has exceeded 9 minutes; 2 CT current exceeds I4(8.2A)

Actions of each load after the frost removal starts:

The compressor and outdoor blowing fan stop, and indoor blowing fan also stops.

55 seconds later the reversal valve is closed and next 5 seconds later the compressor is

started.

Actions of each load after the frost removal ends:

The compressor stops running while outdoor blowing fan immediately runs at high

speed, 55 seconds later the reversal valve is opened and next 5 seconds later the

compressor restores running and indoor blowing fan runs as conditions for cool wind

prevention.

(8) Freeze protection

After the compressor has run for 9 minutes, the system will check temperature of

indoor coil pipe (Ticp). If Ticp is less than -1

fan will stop. They will run again after the compressor stops if both the following

conditions are satisfied:

1) 3 minutes have passed since compressor stops.

2) Ticp exceeds 7

(9) 3 minutes protection for compressor

After compressor stops, it cannot be started until 3 minutes later. During the machine’s

running, if time after loosing power not exceeds 3 minutes, the compressor cannot be

restarted until 3 minutes later after it is reenergized.

10 Power breakdown memory

If the machine suddenly loses power while running, or stops for maintenance or trouble

shooting, it will restart running as the status when it stops after the power is restored.

Note: 1.

(11) Control of water pump

(12) Monitoring of remote network

Through preset interface, the air conditioner is connected to remote control detector

(made by Haier) with 2-core cables for wire communication, to execute instructions sent

from computer or centralized controller via remote control detector and meanwhile send

present running status and trouble information of the machine to remote control detector.

Connection between air conditioner and remote control detector:

Function setting: Continuously press sleep button on the remote controller 10

times in 5 seconds and buzzer on control panel shall beep 4 times.

2. Memory content: Running mode, wind speed setting, temperature setting,

swing status.

3. Cancel: Press sleep button on the remote controller 10 times and buzzer on

control panel beeps 2 times.

a. In cooling (including automatic cooling mode) and dehumidifying modes, the water

pump works if the compressor runs while stops 5 minutes later after the compressor

stops.

b. When water tank is fully filled, the float switch will be off. The water pump will start

to work after a controller has detected this signal and it will continue working for 5

minutes after the float restores to normal state.

c. If the full water signal is detected continuously over 5 minutes, the water pump

indicator lamp will flash to alarm and compressor stops running. The water pump

will run 5 minutes, then pause for 5 seconds before next 5 minutes’ running, ... until

the float restores to normal state, after which the pump will run for 5 minutes then

stop.

PC board

(13) Trial run

Under shut-down state, hold pressing mandatory button. The buzzer will beep once,

then twice after 5 seconds. Release the button to enter mandatory cooling mode, under

which the indoor blowing fan runs at high speed with both the compressor and outdoor

blowing fan working. Press the mandatory button again can end the mandatory mode.
