LED light setting LED light setting instruction There are 4 LED lights for the wall-mounted unit as shown below. They are heating , cooling and run (power supply) , dry . Numerical value displays in middle (display temperature and fault no. etc.) Definitions of LED Panel Cooling LED Ljit is on when the unit is operating in Cooling mode; Heating LED Ljit is on when the unit is operating in Heating mode; Dry LED Ljit is on when the unit is operating in Dry mode; Run LED Ljit is on when the unit is running; 1. In initial power on or reset, Power LED is on after one-second flashing of all LEDs; 2. In normal manual or automatic start, Run LED is on; 3. In normal shutdown, Run LED is off; 4. If the system fails, all LEDs (Mode and Run in current mode) will flash at 1Hz (ON for 0.5sec and OFF for 0.5sec) and at the same time corresponding fault code will be shown in the digital temperature display field. For example: if cooling fault E02 occurs, and will flash, in the above figure will display 02. 18 AMS-SVX03A-EN

Proper use method Set proper room temperature. Too low temperature is unhealthy. Clean the air strainer carefully. Avoid sunlight to lose cold air. AMS-SVX03A-EN Please pull out the battery if the unit is unused for a long term. Adjust the setting temperature properly to save energy. Generally, indoor and outdoor temperature difference is 50C. Air deflector is downward for heating mode and horizontal for cooling mode to make perfect performance. Do not open the door and windows for a long time when the air conditioning is running, otherwise it may reduce the unit efficiency. Do not blowing the cold air directly for a long time and set too-low room temperature, which is unhealthful. Do not spray water or clean the unit with water, which may cause fault or electric shock. Do not damage power cords and signal control wires. Only specified flexible cord can replace the damaged one. This air conditioning allowable voltage fluctuation is 220 240Ġ10%V. This air conditioning can not be used for drying clothes or foods cold-preserved. 19

Maintenance Attention Cleaning of air conditioning must be done with the unit stopped and its main power off, otherwise the risk of electric shock may be resulted in. Never wet the air conditioning, otherwise the risk of electric shock may be resulted in. Make sure not flush the conditioner with water in any case. Volatile liquids like thinner and gasoline may damage the appearance of air conditioning. (Its enclosure could only be cleaned with soft dry cloth and wet cloth dipped with neutral wash solution). Cleaning of panel Attention Remove it before cleaning: Do not do cleaning with water hotter than 45 otherwise it may be discolored or distorted. ņ , 1. As shown in the figure below, apply force to slots at both panel sides in arrow direction to remove the panel. 2. Clean the panel with soft brush, water and neutral cleanser, followed the drying with water throw-off or in a cool place. 3. Reinstall the panel. As shown in the figure below, put the panel pillars at both sides into channels and middle rotor shaft into the slots. Finally cover the panel according to the arrow direction and fix it. Cleaning of air strainer Generally, the air strainer is expected to be cleaned every three months. In case of operation in a dusty environment, its cleaning frequency shall be increased. 1. Remove the air strainer As shown in the figure, apply force to slots at both panel sides in arrow direction to open the panel and pull the air strainer downwards to remove it. 2. Cleaning of the air strainer Generally, the strainer may be cleaned with dust remover or through water washing, and may be washed in the warm water (below 45 ņ ) containing neutral cleanser if it is very dirty (e.g. oil dirt), followed the drying in a cool place; 20 AMS-SVX03A-EN

Maintenance Attention Do not do cleaning with water hotter than 45ņ , otherwise the strainer may be discolored or distorted; Do not dry a wet strainer over the fire, otherwise it may catch fire or become distorted. 3. Installation Install the air strainer in arrow direction with the side marked [front] facing to you. Finally, cover and fix the panel. Check before the beginning of service season Check that both inlet and outlet of the unit are not blocked. Check if earth wire is grounded reliably. Check if the battery of remote controller has been changed. Check strainer for proper installation. If the unit not in service for a long time is to be put into operation again, for smooth start of air conditioner, the main power switch of air conditioning unit shall be set to ON position 24hrs before the operation. Check at the end of service season AMS-SVX03A-EN Check strainer and enclosure. Switch off main power supply of air conditioning unit. 21

Fault analysis Attention Do not repair the air conditioning unit by yourself. Improper repair may cause electric shock or fire. If you need help, please contact Trane customer service center, inviting professionals. Check followings may save your time and money before calling. Phenomenon Analysis Startup air conditioning is not running 3 minutes delay caused by overload protection switch Smell comes out when startup Room air or smoke inhaled before comes out when air change Sound slight running water during running Sound of flowing refrigerant internal Mist comes out from the air outlet sometimes during cooling Quick cooling of room air Squishing sound comes out during and after operation Scraping noise of parts such as panel expansion caused by temperature variation The air conditioning can not work Power failure, power supply not connected Circuit protector trips, high or low voltage Remote controller auto ON is not set Poor air conditioning cooling (heating) performance Improper setting temperature Blocked air inlet/outlet of the indoor unit Blocked air strainer Door or windows is open Fan speed gear is atĐlowđ, other heat source in the room The remote controller can not work Remote controller may crash when replace the battery or others. In Please remove the back cover and pressĐRESETđ button to recover. When the air conditioning is interfered abnormally or the function conversion is too often, you can not control the remote controller accidentally. Just cut off main power and re-energized to recover. Out of receiving range, blocked by barriers. Check and replace batteries if necessary. If you find following conditions, please abort operation and cut off main power supply, then contact Trane customer service center. 22 A harsh sound comes out during operation. The fuse or protector is always disconnected. Pour impurities or water into the machine accidentally. Water leakage happens indoors. Abnormal power supply cord heat. Repugnant smell comes out in operation. AMS-SVX03A-EN
