1. Precautions
Samsung Electronics 1-1
1. Precautions
1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact
replacement parts. (Also, we recommend
replacing parts rather than repairing them.)
3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
equipment may cause problems later-
intermittent contact, for example.
4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.
5. Avoid using an extension cord, and avoid
tapping into a power cord. This practice
may result in malfunction or fire.
6. After completing repairs and reassembly,
check the insulation resistance.
Procedure: Prior to applying power, measure
the resistance between the power cord and the
ground terminal. The resistance must be
greater than 30 megaohms.
7. Make sure that the grounds are adequate.
8. Make sure that the installation conditions
are satisfactory.
Relocate the unit if necessary.
9. Keep children away from the unit while it is
being repaired.
10. Be sure to clean the unit and its surrounding
area.

3. Installation and Operating Instructions
3-1 Installation
3-1-1 Selecting Area for Installation
1. Make sure that you install the unit in an area
providing good ventilation. The air conditioner
must not be blocked by any obstacle affecting the
air flow near the air inlet and air outlet.
2. Make sure that you install the unit in an area that
allow good air handling. The installation area
must be able to endure vibration from the unit.
3. Make sure that you install the unit away from
heat or vapor.
4. Make sure that you install the unit in an area
which is cool and has adequate space.
5. Make sure that you install the unit in an area
away from TVs, audio units, cordless phones,
fluorescent lighting fixtures and other electrical
appliances (obtain a clearance of at least one
meter).
6. Make sure that you install the unit in an area
which provides easy drainage for condensed
water.
7. Make sure that you install the unit in an area not
exposed to rain or direct sunlight.
(Install a separate sunblind if exposed to direct
sunlight.)
8. Make sure that you install the unit in an area
allowing good air movement. Do not install it in
a space that would cause noise amplification of
noise.
9. Fix the unit firmly if mounted in a high place.
Caution:
Do not use the air conditioner in the following environments : greasy areas (including areas near
machines), or marine areas. Contact your local dealer for advice.

3-2 Function Description
3-2-1 Cooling operation mode
The compressor is turned on and off according to the ambient temperature and set temperature.
1) Compressor on and off control
• Compressor on and off control according to the ambient temperature
*The compressor is turned off when "ambient temperature = set temperature
*The compressor is turned on when "ambient temperature = set temperature +1˚C"
2) Default value after power reset ➔set temperature = 24˚C
Fan speed = High
3) Set temperature indicating (setting) range : 1˚C interval from 18˚C to 30˚C.
3-2-2 Fan operation mode
1) If "Fan operation mode" signal is received from remocon or panel.
➔ the compressor is immediately turned off and only fan motor is operated at set blowing speed.
➔ it changes such as "High ➔Med ➔Low ➔ High"( if Fan speed is selected).
2) The initial Fan motor speed is set to "High".
3) The set temperature can not be indicated and set.
3-2-3 Energy saver operation mode
*If the compressor turn off at the cooling operation, the fan motor turn off after operation during the fixation
time only, and operation that energy saver by turn off the fixation time only, and operation that energy saver
by turn off the motor continuously before the condition of the compressor on.
*The fan motor is not operated at flow wind operation.
*Energy saver operation specification at the cooling operation.
1) Fan motor control in compressor on : operate with setting wind speed
2) Fan motor control in compressor off : After compressor off, the fan motor is operated breeze for 2 minutes
and then it turn off.
3) After the fan motor off, the compressor and fan motor is operated normally when the compressor on.

4-2-2 Replacing and refilling the refrigerant oil
1. Change the compressor - DO NOT recharge the oil as the compressor itself is
already charged.
2. Change the condenser .... add 50cc
3. Change the evaporator .... add 50cc
4. When the refrigerant is replaced .... add 30cc oil.
5. After vacuum is completed, the oil is filled through the high pressure side.
6. In the event of a refrigerant leak, generally it is not necessary to add oil.
(Unless the oil has leaked significantly.)
Fill the transparent container with 10cc of oil, and then conduct the test.

5. Troubleshooting
5-1 Basic Checkpoints for Troubleshooting
Check the basic checkpoints first to determine whether it is machine trouble or a problem
in the operation method. When it is not related to the basic checkpoints, perform checking
in accordance with the procedures of troubleshooting by symptom.
1) Is the voltage of the power source appropriate ?
(1) It should be within the rating voltage ±10% range.
(2) The air conditioner may not operate properly when the voltage is out of this range.
2) Is the connection with the fan motor, compressor wire, and starting condenser
appropriately made ?
3) The symptoms listed in the table below are not indicative of machine trouble.
Symptom Cause and check
No operation • Check whether there is power failure or the power plug is pulled out.
• Check whether the unit is stopped as a result of completion
of the sleep time.
• Pull out the power plug for ten seconds, and then insert it again.
Air flows, but • Check whether the Air filter is clogged with dust or is dirty.
no cooling • Check whether the desired temperature is too high. Set the desired
temperature to a lower level than the current temperature.
• Check whether it is in "FAN" mode.
The remocon does • Check whether battery is completely depleted.
not operate • Check whether the battery is properly inserted.
• Check whether the receiving window of the remocon for the assembly
main PCB is blinded.
• Check whether the remocon is affected by jamming due to a neon sign.
No temperature • Check whether the unit is in "FAN" mode.

5-2 Troubleshooting by Symptom
5-2-1 No power
1) Check points
(1) Is the voltage of the power source normal ? (the rating voltage ±10% range.)
(2) Is the electric wire in good contact ?(CN 71, RY 71)
(3) Is the output voltage of the IC01(KA7812) normal ?(DC 11.5V ~ DC 12.5V)
(4) Is the output voltage of the IC02(KA7805) normal ?(DC 4.5V ~ DC 5.5V)
Turn off the power, and then turn it on again five
seconds later.
Replace the assembly main PCB.
Dose the buzzer sound, when the power on?
Check whether the "COOLING ICON" LED lamp is
on, and the operation starts when pressing the
ON/OFF button of the remocon.
Is the primary voltage of the transformer normal?
(the rating voltage ±10% range.)
Is the secondary voltage of the transformer normal?
(AC 13V ~ AC 17V)
Is the F701(3.15A) fuse blown?
Is the rectifier diode(D101~D104) normal?
Are the IC01(KA7812) and IC02(KA7805) normal?
- Is the voltage of DC 17V ~ DC 23V applied at both
ends of the C101 electrolytic condenser?
- Is the voltage of DC 12V applied at both ends of
the C102 electrolytic condenser?
- Is the voltage of DC 5V applied at both ends of
the C103 electrolytic condenser?
Normal operation.
Normal operation.
Replace the fuse.
Check the power cord and electric wire.
Check and replace the trans.
• Check the D101 ~ D104 for cold
soldering.
• Replace the rectifier diode
• Check both ends of the C101 for
short and cold soldering.
• Check the +12V for a short.
• Check the +5V for a short.
• Check and replace the C101~104.
• Check the IC01, and IC02 for cold
soldering and a short.
• Replace the IC01, and IC02.
