AB36NACBEA+AU36NAIBEA AB42NACBEA+AU42NAIBE AProducts 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.

WARNING

CAUTIONWARNING

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, pleaseexplain 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.

- 14-

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

Pour water into a convex joint.

When constructing drain piping for several units, positionthe common pipe about 100 mm below the drain outletof 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 ofindoor placement.Do not ever provide an air vent.The height of the drain head can be elevated up to apoint 500 mm above the ceiling, and when an obstacleexists in the ceiling space, elevate the piping to avoidthe obstacle using an elbow or corresponding gadget.When doing this, if the stretch for the needed height ishigher than 500 mm, the back-flow quantity of drain atthe event of interruption of the operation gets too muchand it may cause overflow at the drain pan. Therefore,make the height of the drain pipe within the distancegiven in the sketch below.Avoid positioning the drain piping outlet at a place wheregeneration of odor may be stimulated. Do not lead thedrain piping direct into a sewer from where sulfur gas

Drainage Test

5. Drain Piping

(a) Drain piping should always be in a downhill grade (1/50~1/100) and avoid riding across an

elevation or making traps.

When connecting the drain pipe to unit, pay suffcient attention not to apply excess force to the pipingon the unit side. Also, fix the piping at a point as close as possible to the unit.

Do not pipe under water

Keep free from traps

Avoid riding across an elevation

(b)

Drainage Test

Conduct a drainage test after completion of the electrical work.

During the trial, make sure that drain flows properly through the piping and that no water leaks

from connections.

In case of a new building, conduct the test before it is furnished with the ceiling.

Be sure to conduct this test even when the unit is installed in the heating season.

Procedures

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.

(d)

(e) 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 drainhose directly into drainage, where the gas with sulfur may be generated.

Backwater bendBecause the drain spout is at the position, which negative pressure may occur. So with the rise of waterlevel in the drain pan, water leakage may occur. In order to prevent water leakage, we designed abackwater 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-absorbingduct. (locally bought)The duct installation work should be finishedbefore the fitment of ceiling.

The duct must be heat insulated.

The specific air-discharging outlet should be installed atthe place where the airflow can be reasonably distributed.

The surface should leave a checking meatus for checkingand 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 irregularouter 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 ifnot taking ceiling inner side as duct, the humidity will also be so high. At this time, use glass fiberto 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.

10. The operation method of fan controllerThrough the fan controller switch in the electric box, the air volume of this unit can be continuouslyadjusted.

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 thechosen 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 thepower 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 capacitynumber 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”.

Rotate this switch

(capacity numbersetting:No. 1 ~ No. 8)

Once the fan controllerhas trouble, this linkercan perform emergencyassistant control. Whenthis linker is connectedto the linker from thePCB, it can operate withtotal load.

When this linker isconnected to the linkerfrom the PCB, throughthe fan speed adjustmentpanel to adjust speed.

(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 , the outdoor blowing fan will stops running; If Ticp ≤ 50 and the outdoor 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 , and the compressor has kept stop state over 3 minutes, then the 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 , the indoor blowing fan will stop running; If 28 Ticp < 38 , the indoor blowing fan will run at low speed; If Ticp > 38 or the compressor has been running for more than 4 minutes, the indoor blowing fan will run at

- 74-


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 , the compressor and outdoor blowing 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

- 75-


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. 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. (11) Control of water pump

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.

(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.

connected with indoor port CN5（1-2-3） through 3-core shield wire. Requirements:

1. Port A only connects with either of indoor port CN5（1）

2. Port B connects with port CN5 (2) of all indoor units.

3. Port C connects with port CN5 (3) of all indoor units.

Dip switch position in central control type: the addresses （SW1:1~4；SW2:1~4）

of indoor units connected with central controller can not repeat. In principle, they

should be in the order from small to big.

Wiring request in central control type: port A-B is connected with indoor port

CN16（A-B）through 2-core shield wire. Requirements:

1. Port A connects with port CN16（A）of all indoor units.
