Rinsing with fresh water, dry the filter and re-assemble. Maintenance Cleaning of the unit Turn off the power switch Do not touch with wet hand Do not clean with hot water or solvent Take off the air inlet grill First switch off the power supply, take off the screw cap, loosen the screw with cross screwdriver. Clean the filter Caution: Clean the indoor(outdoor) unit Clean with warm cloth or neutral detergent, then wipe away moisture with dry cloth. Do not use too hot water(above 40oC), which will cause discoloration or deformation. Do not use pesticide or other chemical detergents. Do not wash filter in hot water above 40oC, which will damage the filter. Do carefully wipe the filter. Use water or vacuum cleaner to remove dust. If it is too dirt, clean with detergent or neutral soap water. Rinsing with fresh water, dry the filter and re-assemble. Maintenance 21 Maintenance Maintenance Maintenance at the end of application season Clean the filter and indoor, outdoor unit, cover the units well. On a fine day, unit shall be started and operate in FAN mode for about half a day unit the inside of the unit becomes thoroughly dry. Turn off the unit operation switch and power on/off. Otherwise, there will be some electricity consumption even the unit is in stop status. Maintenance before beginning of application season Check there are no obstacles in the air inlet and outlet to avoid impairing of working efficiency. Please do attach the air filter to ensure the electrostatic filters not soiled. Otherwise,dirt will come into and damage the unit or bring failures. 22 Trouble shooting Trouble shooting Before asking for service, check the following first. Phenomenon Cause or check points Normal Performance inspection The system does not restart immediately. When unit is stopped, it won't restart immediately until 3 minutes have elapsed to protect the system. When the electric plug is pulled out and reinserted, the protection circuit will work for 3 minutes to protect the air conditioner. Noise is heard: During unit operation or at stop, a swishing or gurgling noise may be heard. At first 2-3 minutes after unit start, this noise is more noticeable. (This noise is generated by refrigerant flowing in the system.) During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperature changes. Should there be a big noise from air flow in unit operation, air filter may be too dirty. Smells are generated. This is because the system circulates smells from the interior air such as the smell of furniture, cigarettes. Mist or steam are blown out. During COOL or DRY operation, indoor unit may blow out mist. This is due to the sudden cooling of indoor air. Multiple check Does not work at all. Is power plug inserted? Is there a power failure? Is fuse blown out? Poor cooling Is the air filter dirty? Normally it should be cleaned every 15 days. Are there any obstacles before inlet and outlet? Is temperature set correctly? Are there some doors or windows left open? Is there any direct sunlight through the window during the cooling operation?(Use curtain) Are there too much heat sources or too many people in the room during cooling operation? 23 24 Installation Manual of Room Air Conditioner Installation of indoor unit selection of installation place Place where it is easy to route drainage pipe and outdoor piping. Place, away from heat source and with less direct sunlight. Place where cool and warm air could be delivered evently to every corner of the room. Place near power supply socket.Leave enough space around the unit. Place, robust not causing vibration, where the body can be supported sufficiently. Installation of outdoor unit selection of installation place Place strong enough to support the unit and will not cause vibration and noise. Place where discharged wind and noise does not cause a nuisance to the neighbors. Place where is less affected by rain or direct sunlight and is sufficiently ventilated,or to install a shield. Place with enough space for smooth air flow. Figure.1 more than 100 cm more than 10 cm more than 10 cm more than 10 cm Figure.2 Figure.3 Installation To prevent interference, place it at least 1m away from other electric machines, such as TV set, radio. There must be no gap between the indoor unit and wall. According to the dimension of the Figure 2 shown nail two cement steel nails on the wall keep 2-3mm out, then hang the back of the unit on them. Remove the front panel,then use two fastening screws to fix the unit on the floor. As Figure 3 shown. Once refrigerant piping and drain piping connections are complete,fill the gap of the through hole with putty. Attach the front panel and front grille in their orginal positions once all connections are complete.
