Make sure the outdoor unit is installed on a stable, level surface with no accumulation of snow, leaves, or trash beside. Make sure the ceiling/wall is strong enough to bear the weight of the unit. Make sure the noise of the outdoor unit does not disturb neighbors. Follow all the installation instructions to minimize the risk of damage from earthquakes, typhoons or strong winds. Avoid contact between refrigerant and fire as it generates poisonous gas. Apply specified refrigerant only. Never have it mixed with any other refrigerant. Never have air remain in the refrigerant line as it may lead to rupture and other hazards. Make sure no refrigerant gas is leaking out when installation is completed. Should there be refrigerant leakage, the density of refrigerant in the air shall in no way exceed its limited value, or it may lead to explosion. Keep your fingers and clothing away from any moving parts. Clear the site after installation. Make sure no foreign objects are left in the unit. Always ensure effective grounding for the unit. Warning Caution All electric work must be performed by a licensed technician according to local regulations and the instructions given in this manual. Before installing, modifying, or servicing system, main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label. Never supply power to the unit unless all wiring and tubing are completed, reconnected and checked. This system adopts highly dangerous electrical voltage. Incorrect connection or inadequate grounding can cause personal injury or death. Stick to the wiring diagram and all the instructions when wiring. Have the unit adequately grounded in accordance with local electrical codes. Have all wiring connected tightly. Loose connection may lead to overheating and a possible fire hazard. Never install the unit in a place where a combustible gas might leak, or it may lead to fire or explosion. Make a proper provision against noise when the unit is installed at a telecommunication center or hospital. Provide an electric leak breaker when it is installed in a watery place. Never wash the unit with water. Handle unit transportation with care. The unit should not be carried by only one person if it is more than 20kg. Never touch the heat exchanger fins with bare hands. Never touch the compressor or refrigerant piping without wearing glove. Do not have the unit operate without air filter. Should any emergency occur, stop the unit and disconnect the power immediately. Properly insulate any tubing running inside the room to prevent the water from damaging the wall. All installation or repair work shall be performed by your dealer or a specialized subcontractor as there is the risk of fire, electric shock, explosion or injury. 2

15 Function and Control 6.2 Description of each control operation 1. Cooling mode (1) Under this mode, the fan and the up swing will operate at setting status. The temperature setting range is 16~30. (2) The unit is stopped because of malfunction of outdoor unit or protection. The indoor unit keeps original operation status and the error code is displayed. (3) Indoor unit is stopped due to mode shock. 2. Drying mode (1) Under this mode, the fan operates at low speed and the swing operates at setting status. The temperature setting range is 16~30. (2) The unit is stopped because of malfunction of outdoor unit or protection. The indoor unit keeps original operation status and the error code is displayed. 3. Heating mode (1) Under this mode, the temperature setting range is 16~30. (2) Working condition and process for heating When the unit is turned on under heating mode, the indoor unit turns to cold air prevention status. When the unit is turned off and the indoor unit has been started up before, the indoor unit blows the residual heat. (3) Protection function: When the compressor is stopped due to malfunction under heating mode, the indoor unit blows the residual heat. (4) Blow residual heat When the unit stops operation as it reaches the temperature point, indoor unit will continue to run for 60s. The fan speed can t be switched during blowing residual heat period. The upper horizontal louver will turn to the defaulted position in cooling. When the unit operates under heating mode or auto heating mode, compressor will be turned on and the corresponding electric expansion valve is more than 65 and the unit stops operation during the operation status of indoor unit. The upper horizontal louver will turn to the defaulted position in heating mode. The indoor unit operates at low speed for 10s and then the unit stops operation. (5) Defrosting, oil-returning As it received the signal of defrosting and oil-returning from outdoor unit, the upper horizontal louver will turn to the minimum angle in cooling. 10s later, the in door fan stop operation. During defrosting and oil-returning process and they are quitted within 5mins, all malfunctions for indoor tube temperature sensor won t be detected. 4. Working process for AUTO mode (Mode judgment will be performed every 30s) Under AUTO mode, standard cooling Tpreset=25 (77 ), standard heating Tpreset=20 (68 ), and standard fan Tpreset= 25 (77 ).
