4 1. Precautions 1-1 Precautions for the Service Use the standard parts when replacing the electric parts. - Confirm the model name, rated voltage, rated current of the electric parts. Repair the disconnection of HARNESS securely when repairing the break down. - If there is any connection error, it causes an abnormal noise and incorrect operation. In case that you assemble or disassemble the products with laying it on the side, do work on the work cloth. - If not, the exterior of products can be scratched. Remove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing the break down. - It protects the danger of fire such as tracking and short. Tighten tightly the service valve of outdoor unit and the cap of charging valve with a monkey spanner. Check the assembly status of parts after repairing the break down. - It should be same as the status before repairing. 1-2 Precautions for the Static Electricity and PL As the PCB power terminal has a weakness for the static electricity, pay attention to it during the repair and measurement. - Work with insulation gloves during the repair and measurement of PCB. Check the distance between the product and the other electronic appliances such as TV, Video, and audio. It should be over 2m. - If not, it causes a bad picture quality or a noise. Repairing the products by consumer should be strictly prohibited. - There is a danger of electric shock or fire due to incorrect disassembly. Samsung Electronics 1-1

5 1-3 Precautions for the Safety Do not pull any electric wires and do not touch an auxiliary power switch with a wet hand. - There is a danger of electric shock or fire. In case any wire or power plug has been damaged, replace it to eliminate any possible danger. Do not bend the power cord by force and do not put any heavy object on the power cord. - There is a danger of electric shock or fire. Do not use multi socket. - There is a danger of electric shock or fire. Ground the product if necessary. - Be sure to ground the product if there is any danger of electric leakage due to water or moisture. Be sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts. - There is a danger of electric shock. In case the product will not be in use for a long time, the battery of remote control should be kept separately. - Leakage of inside fluid can cause break down of remote control. 1-2 Samsung Electronics

Outdoor unit A Gas pipe side Indoor unit C B Liquid pipe side D 2) Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port as shown at the figure. 3) Open the valve of the low pressure side of manifold gauge counter-clockwise. 4) Purge the air from the system using vacuum pump for about 30 minutes. Make sure that pressure gauge show -0.1MPa(-76cmHg) after about 30 minutes. This procedure is very important in order to avoid gas leak. Turn off the vacuum pump. Close the valve of the low pressure side of manifold gauge clockwise. Remove the hose of the low pressure side of manifold gauge. Vacuum Pump 5) Set valve cork of both liquid side and gas side of packed valve to the open position. Valve stem 6) Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf cm with a torque wrench. Stem cap A (gas) 7) Check for gas leakage. - At this time, especially check for gas leakage from the 3 way valve s stem nuts, and from the service port cap. B (liquid) Samsung Electronics 9-5

61 9-5-2 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. 9-6 Samsung Electronics
