Trouble Shooting Followings are not problems Sound of water flowing is not a problem. During unit operation or at stop, a swishing or gurgling noise may be heard. This noise is generated by refrigerant flowing in the system. Sound of cracking is heard. Smell are generated. During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperature changes. This is because the system circulates smells from the interior air such as the smell of cigarettes or the painting on the furniture. During operation, white fog or steam comes out from the indoor unit. When unit is running at places like restaurant, etc. where dense edible oil fumes always exist, this will happen. In cooling operation, unit switches to blowing operation. Unit will not restart after stop. Won't start? No outlet air or fan speed can't be changed in dry mode. In heating operation, water or steam are blown out of outdoor unit. To prevent frost from accumulating on indoor heat exchanger, unit will switch to blowing operation for a while then resume cooling operation. Though ON/OFF button is set to ON, unit won't resume cooling, dry or heating operation in 3 min after it is stopped, this is because of 3-min-delay protection circuit. Please wait 3 minutes Unit will reduce fan speed repeatedly and automatically if room temp. is too low in dry operation. This occurs when frost accumulated on the outdoor unit is removed. (during defrosting operation) In heating operation, indoor fan won't stop even if unit is stopped. After unit stop, indoor fan will go on running until indoor unit cools down. 25
