1. Precautions

1) Turn off the the power. Be sure to turn off the power before attempting to repair the unit such as the disassembly of the unit.

2) Be careful of electric shock When checking the circuit with the power connected in unavoidable circumstances, take special care not to touch the live parts. There is a danger of electric shock.

3) Use of appropriate parts Be sure to use the genuine parts of the relevant model when it is necessary to replace parts. (Replace parts instead of repairing with regard to the malfunctioning of electric contact areas. Never attempt to modify the unit. It is extremely dangerous for the consumer to attempt to repair the unit on his(her) own.)

4) Use of proper tools Use appropriate tools for repair, and use measuring equipment after accurate calibration. Using worn tools may result in problems, including poor contact and poor connection.

5) Avoid damage to electric wire or electric cord. Check the electric cord or electric wire for any damage during repair. Be sure to replace it if damaged.

6) Avoid intermediate connection of the electric cord. Never attempt to make an intermediate connection by cutting the middle area of the electric cord or make a connection to the power receptacle as it is very dangerous, causing problems or fire.

Turn off the sub power switch separately installed.

No connection with the power receptacle

7) Checking of insulation Be sure to check the insulation resistance after completion of the assembly work. (Check whether the insulation resistance of the electric wire and grounding terminal is over 30MΩ by using the insulation resistance tester, and then connect the power source.)

8) Checking of grounding Check the grounding condition, and perform repair if poorly grounded.

9) Checking of installation condition Check the installation condition of the unit, and perform repair if there is any defective area. If the unit remains in an unstable installing condition, install it at a new site.

10) Be careful of children As the repair of the unit involves a lot of dangerous elements, do not allow children to approach nearby during repair work.

Cleaning

Upon completion of the repair, clean the air conditioner and surrounding area, and inform the customer of completion of the repair.

3-3 Check and Test Operation

Be sure to check the following again after completion of installation.

•

1. Check the piping connection area for any gas leakage.

Indoor connection area

Outdoor connection area

3. Is the insulation of the piping in good condition? 4. Is grounding properly made?

Insulation

2. Is the drain hose properly connected?

(In case of disconnecting ground on electric panel board.)

3-2-4(b) Test Operation

After checking, read the owner's instructions care f u l l y, and perform a test operation.

•

Then deliver the unit to the customer. (When delivering the unit, be sure to read carefully and follow the contents of the owner's

i n s t ru c t i o n s . )

Caution

1. Be sure to check whether the service valve is opened before attempting to perform the test operation.

2. Never attempt to start test operation by force pressing the electronic contactor

as it is very dangerous.

(This is very dangerous as the protective device does not work.)

3. Be sure to perform the test operation after installment.

It is easy to start the test operation in winter if you increase the sensor

temperature to 23°C ~25°C by holding the indoor temperature sensor (Cooling operation)

5. Troubleshooting

Troubleshooting pro c e d u re s

1 • Check the items to check first time. 2 • Check the self-diagnostic mode and action method. 3 •

Check in detail the troubled parts according to the sequence of ”trouble shooting by the phenomena”.

5-1 The items to be checked first time

1) Is proper the power voltage ? The power voltage shall be of 187V-253V 50Hz.

2) Is the cable connected correctly between the indoor and outdoor unit? The indoor and outdoor units shall be connected with 8wires including the gro u n d i n g . Check whether the wires of indoor and outdoor units are connected with the correct wire no. and terminal board no.

3) The phenomena in the following table is not related to the fault of air conditioner.

Heating operaation

The compressor does not operated even though the set t e m p e r a t u re is set higher than the indoor temperature. Cooling operation

The compressor does not operated even though the set t e m p e r a t u re is set lower than the indoor temperature .

- Fan speed is not adjusted durning the auto, dry, turbo

and long operation.

Phenomena

The operation of compressor is delayed for 3minutes for the

protection of compressor when it is off and on again.

- The compressor operates nomally after 3 minutes even the lnitial power is on.

The fan speed is automatically adjusted durning the auto, dry,

turo and long operation.

Description

- The temperature is not adjusted durning the auto, dry, turbo and long and fan operation.

-The compressor repeates the stop and start with the interval of several minutes durning dry.

- Durning the heating operation, the lamp “on deice” is on at the control panel and the compressor oprates.

- Durning the heating, the outdoor unit fan motor

repeats start/stop or even the compressor repeats the starts the start snd stop.

- Durning the heating, the compressor and outdoor

unit fan motor operate but indoor unit fan motor does not operate.

Samsung Electronics

- The set temperature is automatically set durning the auto, dry and long operation.

- The wind blow operation is the mode to circulate the indoor air.

- At the dry operation, the set temperature and the indoor temperature are compared to adjust the compressor start/stop time in order to dehumidify.

- The deice operation is being performed in order to melt the frost by outdoor unit and its maximum time is 9 minutes.

- It is the function to prevent the overheating of the indoor

evapolator, where the temperature of indoor unit heat exchanger

reaches 52°C, the normal operation is done.

-This is the function to prevent the cooling air incoming to the indoor, where the temperature of indoor evaporator reaches 27°C, the indoor fan motor operates.
