Suspension hook Compound gauge High pressure gauge Hand wheel 3) Connect the tank to refill with refrigerant. 4) Set the unit to cool operation mode. Finger tight fittings For mounting other and of hose when not in use Connected to high pressure side Charging line 5) Check the pressure indicated by the pressure gauge(low pressure side). * Standard pressure is should be 9.0~10.0kg/cm2 in a regular, high operation mode. 6) Open the refrigerant tank and fill with refrigerant until the rated pressure is reached. * It is recommended not to pour the refrigerant in too quickly, but gradually while operating a pressure valve. 7) Stop operation of the air conditioner. 8) Close the 3-Way valve, disconnect the pressure gauge, and open the 3-Way valve again. 9) Close the cap of each valve. Samsung Electronics 7 DB98_20429A(1)_1 12/24/04 10:55 AM Page 8 Operating Instructions & Installation 2-4-3 "Pump down" Procedure Pump down will be carried out when an evaporator is replaced or when the unit is relocated in another area. 1) Remove the caps from the 3-Way valve and the 3-Way valve. 2) Turn the 3-Way valve clockwise to close and connect a pressure gauge (low pressure side) to the service valve, and open the 3-Way valve again. 3-Way Valve 2-Way Valve 3) Set the unit to cool operation mode. (Check if the compressor is operating.) 4) Turn the 3-Way valve clockwise to close. 5) When the pressure gauge indicates "0" turn the 3-Way valve clockwise to close. 6) Stop operation of the air conditioner. 7) Close the cap of each valve. Relocation of the air conditioner • Refer to this procedure when the unit is relocated. • Carry out the pump down procedure (refer to the details of 'pump down'). • Remove the power cord. • Disconnect the assembly cable from the indoor and outdoor units. • Remove the flare nut connecting the indoor unit and the pipe. • At this time, cover the pipe of the indoor unit and the other pipe using a cap or vinyl plug to avoid foreign material entering. • Disconnect the pipe connected to the outdoor unit. At this time, cover the valve of the outdoor unit and the other pipe using a cap or vinyl plug to avoid foreign material entering. • Make sure you do not bend the connection pipes in the middle and store together with the cables. • Move the indoor and outdoor units to a new location. • Remove the mounting plate for the indoor unit and move it to a new location. 8 Samsung Electronics DB98_20429A(1)_1 12/24/04 10:55 AM Page 9 3.

Troubleshooting 6-1 Items to be checked first 1. The input voltage should be rating voltage ±10% range. The airconditioner 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 5 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the airconditioner 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 airconditioner. No Operation of air conditioner Explanation 1 The OPERATION indication LED(BLUE) blinks when a power plug of the indoor unit is plugged in for the first time. It indicates power is on. The LED stops blinking if the operation ON/OFF button on the remote control unit is pushed. 2 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 case of heat pump model] In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate. 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. 3 Fan speed setting is not allowed in DRY( The speed of the indoor fan is set to LL in DRY mode. Fan speed is selected automatically in AUTO mode. 4 Compressor stops operation intermittently in DRY( mode. 5 Timer LED(YELLOW) of the indoor unit lights up and the air conditioner does not operate. Timer is being activated and the unit is in ready mode. The unit operates normally if the timer operation is cancelled. 6 The compressor stops intermittently in a COOL mode or DRY mode, and fan speed of the indoor unit decreases. 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. 7 [In case of heat pump model] Compressor of the outdoor unit is operating although it is turned off in a HEAT mode. When the unit is turned off while de-ice is activated, the compressor continues operation for up to 9 minutes (maximum) until the deice is completed. 8 [In case of heat pump model] The compressor and indoor fan stop intermittently in HEAT mode. 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. 9 [In case of heat pump model] Indoor fan and outdoor fan stop operation intermittently 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 Samsung Electronics ) mode. ) Compressor operation is controlled automatically in DRY mode depending on the room temperature and humidity. 29 DB98_20429A(1)_1 12/24/04 10:55 AM Page 30 Troubleshooting 4.
