Troubleshooting The following cases are not troubles. Water flow sound is heard. During operation, the air conditioner may sometimes exhibit a sound of "clatter" or "rumble". This is the common sound of refrigerant flow but not a trouble. "Hua-Hua" A sound of "Pi-Pa" is generated. This is caused by the thermal expansion or cold shrinkage of plastics. Smells are given off. Sometimes there are smells in the air flow from the indoor unit.
Troubleshooting In DRY operation, when the room temperature reaches 2* higher than temp. setting,the unit will run at "lOW"fan speed regardless of fan speed setting. During DRY operation, there is no air sent out or fan speed cant be changed. In HEAT mode, the outdoor unit generates water or steam. This occurs during removal of the frost (in defrosting operation) on the radiator of outdoor unit. Defrost operation In HEAT mode, the indoor fan still keeps running even the unit operation stops.
When fault occurs Poor cooling or heating Is the operation controller adjusted as required? Is there any door or window Are there any obstructs before the air inlet or outlet? left open? Poor cooling Is there any other heat source in the room? Is there any direct sunlight into the room? Are there too many people in the room? If, after the above checks and the corresponding corrective actions, the system remains abnormal operation, or the following facts appear, please turn off the air conditioner and t

Installation procedure Electrical requirements l The power supply shall be connected from the outdoor side. (For models with electric-aided heating function, the power supply to the indoor unit shall be connected at the indoor side The power cord size is 3 x (1.25-1.5)mm2, type of YZW). l A separate power circuit shall be supplied and connected by a qualified electrician according to the wiring rules specified in the corresponding national standard. l A current leakage breaker must be installed.
Installation procedure ! Choosing the installation location Caution Please do not install the unit in places where flammable gases may be leaked. In case that gas is leaked and accumulated around the unit, it may cause dangers of fire etc. The indoor unit shall be installed at locations where cold and hot air could evenly circulated. The following locations should be avoided: l Places with rich saline matters (seaside regions).
Installation procedure Installation of indoor unit ! Warning lThe unit shall be installed at locations enough to support the unit. If not, the air conditioner may fall down and cause personal injury. lThe unit shall be installed according to the specifications to resist to strong wind and earthquake. Improper installation may cause dangers of unit falling down etc. After selecting the unit installation location, proceed the following steps: 1.
