Introduction to Spare Parts Air ourlet blade (adjust air outlet direction by the air direction adjusting button on remote controller) Suction grill Air filter (located in the suction grill) 6
Maintenance [Clean air filter] NOTE When having to clean, don't dismantle air-filter,otherwise may cause faults. In the environment where there is too much dust, air filter should be cleaned for more times. (about half a year one time) 1. Open inlet grill Pull the two handles at the same time, slowly draw them out. (B) Wash with water. With too much dust, use soft brush and neutral detergent. Swing off the water, and then place in cool place. 4.
Maintenance Seasonal Reserve Post-season Care Operate the unit with FAN mode on a fair day for about half a day to dry the inside of the unit well. Stop operation and turn off the power supply switch .Electric power is consumed even the air conditioner is in stop. Clean the air filter, indoor unit and outdoor unit,and cover the unit with dustcoat. Pre-season Care See that there is no obstacles blocking the air inlet and air outlet of both indoor and outdoor unit to avoid reduce the working efficiency.
Trouble Shooting The followings are not malfunction Water flowing sound is heard When the air conditoner is started, when the compressor starts or stops during operation or when the air conditioner is stopped,it sometimes sounds "Bi- Bi-"or "Godo-Godo". It is the flowing sound of the refrigerant , not a malfunction. Hua Hua Cracking sound is heard This is caused by heat expansion or contraction of plastics It smells. Air blown out from the indoor unit sometimes smells.
Trouble Shooting Air does not blow or the fan speed cannot be changed during drying. In DRY mode, when room temperature becomes 2 higher than temperature setting, unit rill run intermittently at LO speed regardless of FAN setting Water or vapor generated from the outdoor unit during heating. During heating,indoor fan is still running even unit is stopped. To get ride of the excess heat, indoor fan will continue running for a while after unit autom-atically stops.
When Trouble Happens Insufficient cooling or heating The operation controller adjusted as required Air filter too dirty ? Horizontal swing louver upward ? (in HEAT mode) Any obstacle exists at the air Door or window left opened ? inlet or outlet? Insufficient cooling Any other heat sources in the Sunlight direct into the room ? room? Too crowed in the room ? Cooled air blown out ( when heating) When the air conditioner does not operate properly after you have checked the above-mentioned items or when
