SERVICE Manual

1. Precautions
Samsung Electronics 1-1
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 megohms.
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
1. Make sure that you install the unit in an area that
provides 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 which
can endure the weight and vibration of 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 where
the cooled air can be evenly spread in a room.
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 sun-
light.)
8. Do not install the unit in an area subjected to noise
or vibration amplification which may affect your
neighbor.
(Fix the unit firmly if mounted in a high place.)
*When selecting the area for installing the unit, be sure to obtain approval of the customer.
Caution:
Do not use the air conditioner in such areas as a greasy area(including machine oil),
saline area(sea side), or sulphuric area(hot spring). When using the air conditioner in these areas,
special maintenance is required. Contact your local dealer or our service center for advice.

Installation and Operating Instructions
3-2-9 About the safety devices
1. High temperature release : If temperature of the "indoor pipe thermistor" increases over the specified value during heating
operation, following operation is carried out for safety of the equipment.
A condition : temperature of "indoor pipe thermistor" is below 47˚C
B condition : temperature of "indoor pipe thermistor" is between 58˚C and 63˚C
C condition : temperature of "indoor pipe thermistor" is over 63˚C
1) High temperature release operation OFF condition = A condition
-> compressor ON (only in THERMO ON condition)
-> fan motor speed = set fan speed and cool blowing inhibiting operation
2) High temperature release operation ON condition = B condition
-> compressor ON
-> fan motor speed = Only HIGH operation regardless of previous selection
3) High temperature release operation ON condition = C condition
-> fan motor speed = set fan speed
-> compressor OFF
2. Low temperature release : If temperature of the "indoor pipe thermistor" decreases below the specified value during cooling
operation, following operation is carried out for safety of the equipment.
A condition : temperature of "indoor pipe thermistor" is below -1˚C for more than 6 minutes
B condition : temperature of "indoor pipe thermistor" is over 5˚C
1) Low temperature release ON condition = A condition
-> compressor OFF
-> fan motor "set fan speed"
2) Low temperature release OFF condition = B condition
-> The compressor is turned on if ON condition is satisfied after comparing the ambient temperature with the set
temperature
-> fan motor "set fan speed"
[Detailed description]
1) If temperature of "indoor pipe thermistor" is below -1˚C for more than 6 minutes, the fan motor continues to operate
at the set fan speed and the compressor is turned off(Low temperature release operation)
2) If temperature of the "indoor pipe thermistor" increases over +5˚C during low temperature release operation, normal
operation is recovered
: compressor ON, fan mtor set fan speed -> Low temperature release operation OFF
3) If temperature of "indoor pipe thermistor" increases over 0˚C during counting 6 minutes below -1˚C, the counter is
reset.

Installation and Operating Instructions
1) Deicing detecting condition
• If one of A, B and C conditions is satisfied, deicing operation is carried out.(AUBUC)
• If counting time is overlapped due to detection reference temperature change during counting of the deicing con-
dition, deicing operation starts when the counting time is finished first.
• The maximum counting time is 100 minutes.
- During deicing operation, the left and right swing motor is turned off and stops at the position before swing.
- If operation is turned off during deicing operation, it is finished and the compressor is turned off.
-> Deice lamp ON, fan motor OFF.
2) Display indication.
• The deice lamp is turned on additionally during deicing cycle.
• Only the deice lamp is turned off when deicing is finished.
3) In case of turning off during deicing operation.
• The compressor is turned off after finishing the deicing operation.
• The deice lamp is turned on during deicing cycle and is turned off when deicing is finished.
4) In case of changing mode to cooling operation during deicing operation.
• Cooling operation is carried out after carrying out deicing operation.
• After the compressor is turned off and 1 minutes is passed, it is restarted.
5) Load operation during deicing operation.

Installation and Operating Instructions
4. Cool blowing inhibiting control : In order to inhibit cool blowing during heating operation, the fan motor is operated when
temperature of the "indoor pipe thermistor" is above the specified value.
• The fan motor speed is controlled according to the temperature of condition of the "indoor pipe thermistor".
< Compressor OFF -> Compressor ON >
1) When the "indoor pipe thermistor" temperature is increasing
"indoor pipe thermistor" temperature = below 32˚C --> fan motor OFF
"indoor pipe thermistor" temperature = over 32˚C --> fan motor speed "set blower speed"
2) When the "indoor pipe thermistor" temperature is decreasing
"indoor pipe thermistor" temperature = over 30˚C --> fan motor speed "set blower speed"
"indoor pipe thermistor" temperature = below 30˚C --> fan motor speed "Low"
3) But if the compressor is operating, the fan motor is not turned off but is operated weakly even if the "indoor pipe ther-
mistor" temperature decreases.

3-2-10 Compressor delayed operation and 4-way valve delayed operation
The compressor is turned on after 3 minutes from power resetting or compressor turning off during cooling
or heating operation.
1) The compressor can be turned on after "3 minutes delay" from power resetting or compressor turning off.
2) The 4 way valve is turned off/on after "2 minutes and 55 seconds delay" in the on/off condition.
(during heating operation)
3) The operation is stopped after "2 minutes and 55 seconds delay" in the off condition when the 4 way valve is
turned on.

4-2-1 Oil quality
4-2-2 Replacing and refilling the refrigerant oil
1. Replacing the compressor - Do not fill the system with oil as the compressor is already charged.
2. Replacing the condenser - Refill 50cc.
3. Replacing the evaporator - Refill 50cc.
4. Replacing the refrigerant - Refill 30cc.
5. The high pressure side is filled up with oil after the vacuum is completed.
6. When the refrigerant leaks, it is generally not necessary to refill the oil if the leakage is not severe.
Fill the transparent container with 10cc of oil, and then conduct the test.
