Precautions
1-1 Installing the air conditioner
O Users should not install the air conditioner by themselves.
Ask the dealer or authorized company to install the air conditioner except the window-type air conditioner in U.S.A and Canada.
O If you don’t install the air conditioner properly, it may cause a fire, a water leakage or an electric shock.
O You must install the air conditioner according to the national wiring regulations and safety regulations.
O Install the indoor unit higher than 2.5m from the floor to avoid the injury caused by the operation of the fan. (except the window-type air conditioner)
O
The manufacturer is not responsible for any accidents or injury caused by an incorrect installation.
When installing the built-in type air conditioner, keep all electric cables such as the power cable and the connection cord in pipes, ducts, or cable channels to protect them from the danger of impact or any other incidents.
O More than 2 indoor units should be installed when you use Free Joint Multi air conditioner.
O
AJ020JCJ2CH
- 77 018/024 77 indoor unites cannot be connected.
AJ024JCJ3CH
- 77 024 7777 indoor units cannot be connected.
d a n g e r o u s
Avoid Dangerous Contact
1-2 Power supply and circuit breaker
O If the power cord of the air conditioner is damaged, it must be replaced by the manufacturer or a qualified person in order to avoid a hazard.
O The air conditioner must be plugged into an independent circuit if applicable or connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be incorporated in the fixed wiring with a contact opening of >3mm.
O
Do not extend an electric cord to the air conditioner.
O
The air conditioner must be plugged in after you complete the installation.
No Tapping and No Extension Cords
Samsung Electronics 1-1
1-3 During operation
O
Do not repair the air conditioner at your discretion.
It is recommended to contact a service center directly.
O
Never spill any kind of liquid on the air conditioner.
If this happens, turn off the air conditioner and contact an authorized service center.
O
Do not insert anything between the airflow blades to prevent damage of the inner fan and consequent injury. Keep children away from the air conditioner.
O
Do not place any obstacles in front of the air conditioner.
O Do not spray any kind of liquid into the indoor unit. If this happens, turn off the air conditioner and contact a service center.
O Make sure that the air conditioner is well ventilated at all times:
Do not place a cloth or other materials over it.
O
Remove the batteries if you don’t use the remote control for a long time. (If applicable)
O
Use the remote control within 7 meters from the indoor unit. (If applicable)
No children Nearby
1-4 Disposing of the unit
O
Before throwing out the air conditioner, remove the batteries from the remote control.
O When you dispose of the air conditioner, consult your dealer. If pipes are removed incorrectly, refrigerant may blow out and cause air pollution. When it contacts with your skin, it can cause skin injury.
O The package of the air conditioner should be recycled or disposed of properly for environmental reasons.
1-5 Others
O Never store or load the air conditioner upside down or sideways to prevent the damage to the compressor.
O
Young children or infirm persons should be always supervised when they use the air conditioner.
O Max current is measured according to IEC standard for safety.
O
Current is measured according to ISO standard for energy efficiency.
O When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removingthe connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.
O
Pump Down Procedure (When removing the product)
- Turn on the air conditioner and select Cool mode to run the compressor for 3 minutes.
- Release the valve caps on High and Low pressure side.
- Use L wrench to close the valve on the high pressure side.
- Approximately 2 minutes after, close the valve on the low pressure side.
- Stop operation of the air conditioner.- Disconnect the pipes.

4-3 Items to be checked first
1. The input voltage should be rating voltage ±10% range.
The air conditioner may not operate properly if the voltage is out of this range.
2. Is the link cable linking the indoor unit and the outdoor unit linked properly?
The indoor unit and the outdoor unit shall be linked by 4 cables.
Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
Otherwise the air conditioner may not operate properly.
3. When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction of the air conditioner.

Operation of air conditioner
In a COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the INDOOR FAN should operate.
In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate.
Explanation
In happens after a delay of 3 minutes when the compressor is reoperated. The same phenomenon occurs when a power is on.
As a phenomenon that the compressor is reoperated after a delay of 3 minutes, the indoor fan is adjusted automatically with reference to a temperature of the air blew
2 Fan speed setting is not allowed in AUTO( ) or
DRY( ) mode.

Compressor stops operation intermittently in
DRY( ) mode.
Compressor of the outdoor unit is operating although it is turned off in a HEAT mode.
Timer LED( ) only of the indoor unit lights up and the air conditioner does not operate.
The compressor and indoor fan stop intermittently in
HEAT mode.
Indoor fan and outdoor fan stop operation intermittently in a HEAT mode.
The compressor stops intermittently in a
COOL mode or DRY mode, and fan speed of the indoor unit decreases.
The speed of the indoor fan is set to LL in DRY mode.
Fan speed is 5 steps and is selected automatically in AUTO mode.
Compressor operation is controlled automatically in DRY mode depending on the room temperature and humidity.
When the unit is turned off while de-ice is activated, the compressor continues operation for up to 12 minutes (maximum) until the deice is completed.
Timer is being activated and the unit is in ready mode.
The unit operates normally if the timer operation is cancelled.
The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protect the compressor from overheated air in a HEAT mode.
The compressor operates in a reverse cycle to remove exterior ice in a HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heater operation.
The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozen depending on the inside/outside air temperature.

- If the auto addressing does not work according to the indoor unit capacity, model or installation condition,apply the manual addressing.
7 When SW01 set "0"on Auto address mode,it means you install the maximum number of indoor unit.
1) Installation ID Unit Number=MAX Installation ID Unit Number of OD Unit.
® Don't need set SW01.
2) Installation ID Unit Number<MAX Installation ID Unit Number of OD Unit.
® Pls set SW01 as the number of which you install the indoor unit.
7 On Manual address mode,you must set SW01 as the number of which you install the indoor unit.
- This mode is for finding the combination between indoor unit and each valve on the outdoor unit. Because refrigerant flow is controlled with EEV in the outdoor, controller should know which EEV will control which indoor unit.
- Once "PIPE CHECK MODE" is done normally, each indoor unit will remember the given address number by the outdoor unit and no need to do this checking. But in case of listed below, PIPE CHECK MODE should be done again.

4-6 PCB Inspection
4-6-1 Cautions for Part Replacement
1. The human body carries much static electricity.
Before touching a part for repair, replacement or the similar purpose, be sure to touch a grounded metallic portion by hand to let the static electricity go through the metallic portion to the earth.
Especially when handling any micro computer or IC, carefully remove such static electricity before touching them.
2. When repairing any part on a work bench, be sure to place an insulative sheet on the bench and always keep the sheet surface neat without any metal fragments. If any such fragment touches a part, a secondary trouble will possibly be caused in the part.
3. Before replacing any parts, be sure to turn off the power supply. If such replacement is done with the power supply kept on, an electric shock, short circuit or destruction of a part may result.
4. During replacement or repair of a part, carefully handle it : The printed circuit board has fine lead wires
(jumper wires) and glass-made parts (diode) on its substrate.
So if a circuit board is roughly handled, such lead wires and parts will be easily broken or damaged by bending or shock.
5. When soldering the lead wires of any new part, be sure to polish them using an emery paper or the like before soldering them.
Since the lead wires of any new part are covered with an oxide film, solder cannot adhere to the lead wires if not polished.
4-6-2 Procedure
12-4-2
The parts should be replaced in the following procedure.
Check for any faulty part.
6. When soldering any part, care should be exercised not to apply any high-wattage soldering iron to the part for a long time. Some parts are of so low a heat resistance that they may be broken or have the properties changed if a soldering iron is so applied
(Otherwise, the pattern may possibly be separated and raised).
7. The heat of the soldering iron should be transferred to the entire object to be soldered. If the solder pieces are not well fused due to insufficient transfer of the heat from the soldering iron, no satisfactory electrical continuity can be assured even if the soldered objects appear well connected to each other.
8. The solder used should be limited to a minimum.
If excessive solder is used, it will cause inter-pattern contact, which may cause malfunction of the circuit.
9. Although some part of the PCB surface are coated with coating material for protection from dust and dirt, soldering is also available to the coating part.
Because this coating is thin and is weak for soldering heat.
But coating material remaining on the solder part should be cleaned up before soldering a new component to prevent the solder part from becoming bad conduction.
10. After replacing a faulty PCB by a new one, the same
address setting must be applied to the new PCB.
(refer to the page 4-19 ~ page 4-24)
11. When connected to an outdoor unit manufactured after
June, 2011, a new option code is not needed.
Detach the faulty part.
Replace it with a new part.
Set an address.
Check the operation of the new part.
The repair is completed.

It would be the best choice to use the standard tube length to keep the basic quality of Room Air conditioner, for example cooling capacity, sound level, vibration level, and reliability.
But, according to a certain different installation condition, the connection tube length could be changed in the recommendation length that is shown above.
In this case, installer should keep the installation condition to keep the quality of Room Air conditioner.
O Refrigerant should be charged additionally as written above according to the change of the length of the connection tube.
It needs to affect the decrease in cooling and heating capacity or of the reliability of compressor that may be caused by a lac k of refriger ant.
O Installation position difference between the indoor unit and the outdoor unit should not exceed over than 15 meters.
O When the connection pipe is been extended longer than 5 meters, it might need to change the diameter of the electrical wire to a larger size in order to keep a voltage drop for starting room air conditioner is not less than 85% of the rated voltage. And then, a voltage meter will be useful to check the rate of the voltage drop.

Description
The cooling is weak.
When it is hot outside, its cooling capacity decreases due to the increase of the ambient temperature.
When the dust filter gets blocked or warm outside air gets in, the cooling capacity will decrease. So, make sure to clean the dust filter frequently, prevent heat loss by closing the doors and insulate the cooling area by using curtains, blinds, shades or window tinting.
The cooling is good generally. But, it gets weak when it is considerably hot.
It occurs when the outdoor unit is exposed to direct sun light and heat-up air is not ventilated well.
So, set up a sunblind over the outdoor unit and keep stuff away from the unit to increase the ventilation. When the cooling capacity decreases during a heat wave, clean the heat exchanger of the outdoor unit or spray some cold water to the heat exchanger to increase the cooling capability.
The cooling is weak. Does it need refrigerant charging?
It is not correct charging refrigerant regularly. Except that you have moved in several times or the connection pipes are broken, the refrigerant does not run low. So, when refrigerant is additionally charged, it could be costly and cause a product's failure. When the refrigerant leaks, all of it will escape in a short time resulting in cooling failure and no water coming out of the drain hose. So, if water comes out from the drain hose, it indicates the normal operation of the product and it does not need refrigerant charging.
It fails to do cooling.
When the air conditioner is set to Ventilation or the desired temperature is set higher than the current temperature, it fails to do cooling. In this case, select Cooling or set the desired temperature lower.
It floods the floor.
Place the drain hose properly. When it is not placed properly, the drain water would flow back flooding the floor. So, straighten out the drain hose for the water to be drained well.
Water drips at the drain connection (service valve) of the outdoor unit.
When a glass bottle is taken out of the refrigerator, moisture gets condensed on its surface due to the temperature differences. The same principle applies to the air conditioner. When cold refrigerant goes through the copper tube, moisture gets condensed on the surface of the tube and the connection areas. To prevent the water condensation, the pipes are insulated. But, the connection areas of the outdoor unit are not insulated for the purpose of maintenance or repair, and water gets condensed due to the temperature differences and drips down. Generally, it evaporates right away. But, when it drips much during muggy days, put a water pan on the floor.
It leaks even though a drain pump is used.
It occurs when the drain pump is plugged out or it is out of order. Check the power of the drain pump and the position of the drain hose, and when the pump is faulty, contact the drain pump manufacturer.
Samsung Electronics do not manufacture drain pumps. So, we are not able to correct the drain pump problems.
Whenever the air conditioner is turned on, it irritates my eyes and gives me a headache.
There are no components in the air conditioner irritating the eyes and sending out chemical smells.
But, when the air conditioner is turned on, other smell sources are sucked into the air conditioner and get out of it. So, find and root out the smell sources. Generally, it occurs at a interior renovated place, a pharmacy, a gasoline handling place, a tire shop, a second-hand book shop or an electronic

Whenever the air conditioner is turned on, it stinks.
There are no components in the air conditioner sending out chemical smells. But, when the air conditioner is turned on, other smell sources are sucked into the air conditioner and get out of it. So, find and root out the smell sources. Generally, when the drain hose is taken out to the washing room or there are sources of smells such as a diaper bin, a shoe shelf or a socks bin, bad smells generate.
Also, it occurs where glass cleaners or air fresheners are used; when they are sucked in interacting with dusts and moistures inside, bad smells generate. These kinds of organic materials noxious to human bodies. So, we recommend against the use of them.
Whenever the air conditioner is turned on, it smells sour.
When the room is papered recently, its paste smells would be sucked inside. Also, when the air conditioner is installed in the study room of young boys loving sweat-generating activities such as the basketball, excessive sweats evaporate and get sucked into the air conditioner resulting in bad smells. So, find and root out the problem or refresh the room frequently.
Whenever the air conditioner is turned on, it smells musty.
It is due to the improper keeping of the product after its use. When keeping the product, dry up the inside with the operation of Ventilation to prevent must. When the product is kept without drying up the inside with Ventilation, mold would grow inside resulting in must. So, open the windows and switch on the Ventilation function to get rid of the saturated smell inside.
Whenever the air conditioner is turned on, it sends out bad smells such as stale smells.
It occurs generally when there are pet animals in the house. Their smells stay at the same place.
But, when the air conditioner is turned on, the air gets circulated resulting in the circulation of the smells. So, find and root out the problem or refresh the room frequently.
It sends out bad smells.
When the air filter is filthy, it could send out bad smells. So, clean the filter and ventilate the room with the windows open while operating the Ventilation function.
It won't start.
There is a power failure or it is plugged out. Also, check if the power distribution panel is switched off.
It goes off during operation.
When the hot air does not escape properly, it goes off during operation. It occurs when it does not ventilate properly because the outdoor unit is covered, the back of the outdoor unit is blocked by a cardboard or a plywood panel, and the front of the outdoor unit is blocked by the closed window or other obstacles. Clear the above obstacles from the outdoor unit.
It generally works properly. But, when it's considerably hot, it goes off during operation.
It occurs when the outdoor unit is exposed to direct sunlight and the hot air does not escape properly.
Set up a sun blind over the outdoor unit and clear the neighboring obstacles from the outdoor unit to provide good ventilation. When it goes off frequently during a heat wave, it would prevent the turn-off and increase the cooling capacity cleaning the outdoor unit or spraying some water to the heat exchanger.

The remote controller won't operate.
When the batteries run out or the transmitter or receiver of the remote controller is blocked by obstacles, change the batteries or keep the obstacles away from the controlling area. Also, the remote controller may not work under intensive light from a 3-wave length lamp or a neon sign due to the EMI.
In this case, take the remote controller closer to the receiver.
Who installs the air conditioner? (Relocation/Re-installation)
When relocating or re-installing the air conditioner, make sure to contact Samsung Electronics Service
Center or Authorized Service Agent and have them to do the job.(If not, it could cause personal injury or product damage.)
The cost for the relocation/re-installation of the air conditioner is subject to the customer's expense.
There is a cost table. But, our service engineer needs to visit to total up the cost correctly.
When you move in, make sure to contact Samsung Electronics Service Center or Authorized Service
Agent in advance to streamline the process.
Is it possible to install the outdoor unit outside?
It is possible to install it at a designated place in the apartment or on the rooftop nearby.
But, it's illegal hanging an angle iron case with the outdoor unit in it outside the apartment. Also, it is illegal obstructing passers-by with the outdoor unit installed outside.
What can be done to install the outdoor unit facing the road because it is a commercial building?
The following is an excerpt from Building Code going into effect from JUNE 1st 2005. "The exhaust pipe of a cooling or ventilation facility installed in a building adjacent to the streets of commercial or residential areas shall be installed higher than 2m to prevent the exhaust air from blowing directly to passers-by and the current facilities shall be corrected by MAY 31st 2005." So, please install it higher than 2m or not to blow the hot exhausting air directly to passers-by.
What about installing a windscreen during installation not to blow hot air directly to passers-by?
When the hot air from the front of the outdoor unit is blocked, the product's performance will be affected and it will fail to operate properly. So, keep it at least 300mm away from its surrounding walls and give it good ventilation.

Four factors of air suppliers
The human body keeps regular temperature regarding the human body's freshness.
For keeping freshness, heat generated from human body should emit outside of the body by air circulation, conduction, emission, and evaporation. The human body feels freshness when the emission rate is 40~45%, which was emitted by a radiation when it is comfortable and warm, and air circulation and conduction is 20~30%, and evaporation is 20~24%.
It sometimes may depends on seasonal factor, wearing condition, age, sex and mental state other than indoor environment.
But generally the value of fresh indoor temperature is that below 0.2(m/s) of indoor air circulation, the temperature is 21~28 Ň C when the wall temperature is the same as the indoor's and relative humidity is 30~31% in summer, the winter temperature is
20~24 Ň C and relative humidity is 30~60% in winter.
