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 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.
Fig. 1-1 Avoid Dangerous Contact
Fig. 1-2 No Tapping and No Extension Cords

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 (75˚F)
Fan speed = High
3) Set temperature indicating (setting) range : 1˚C(1˚F) interval from 18˚C to 30˚C. (64˚F to 86˚F)
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.
