FILTER CLEANING OPERATION (Filter Cleaning Unit Operation Check, page 10) CAUTION Do not put your fingers or a stick etc into the top part of the indoor unit during filter cleaning operation. It may result in injury or malfunction. 1 Automatic filter cleaning operation • Automatically cleans the micro mesh stainless filter when the basic air-conditioning operation such as cooling has ended.
n Automatic filter cleaning is not performed if the air conditioner operation is stopped by Sleep Timer or Off Timer function. If you use Sleep Timer or Off Timer every time, manual filter cleaning should be executed approximately once every 2~3 days. (Page 34) However, if no manual filter cleaning is performed, automatic filter cleaning will be performed approximately once a week after the air conditioner operation is stopped by Sleep Timer or Off Timer function to protect the device.
FILTER CLEANING OPERATION (continued) 2 Manual filter cleaning operation • Use the remote controller to run filter cleaning operation when the air conditioner operation is stop. • If the air conditioner is not in use for a long period, it is recommended to manually run filter cleaning before it is initialized. Press the (MANUAL CLEAN) button when the air-conditioner stops.
Operate the manual filter cleaning operation. (Page 34) Set to prohibit the filter cleaning operation again. (Method of setting 1, 2, 4, page 34) • If the filter cleaning is performed after a long interval, dust on the micro mesh stainless filter may not be completely cleaned just by one cycle of filter cleaning. To avoid this, frequent filter cleaning is recommended. (Standard cleaning frequency is once every 2~3 days.
MAINTENANCE WARNING • Before cleaning, stop unit operation with the remote controller and turn off the circuit breaker. CAUTION • • • • Do not expose the unit to water as it may cause an electric shock. For cleaning inside the air conditioner, consult your sales agent. Avoid using detergent when cleaning the heat exchanger of the indoor unit. Unit failure may result. When cleaning the heat exchanger with a vacuum cleaner, make sure to wear gloves so as not to injure your hands on the heat exchanger fins.

ENGLISH UNDERSTANDING THE OPERATING MECHANISM NAMES AND FUNCTIONS OF EACH PART (Page 4) Heating capability • This room air conditioner utilizes a heat pump system that absorbs exterior heat and brings it into a room to be heated. As the ambient temperature gets lower, heating capability will also lower. In such a situation, the PAM and inverter work to increase compressor rpm to keep the unit’s heating capability from decreasing.
Make sure the room is ventilated when operating the air conditioner at the same time as other heating appliances. 3. Make efficient use of Air Quality Monitor and Mold Monitor when going out. (Refer to page 21~22 on Air Quality Monitor and Mold Monitor) 4. Make efficient use of the timer before going to sleep. (Refer to page 28~31 on using the timer) 5. The following must never be used for cleaning the indoor and outdoor units: • Benzine, thinner and scrub can damage plastic surfaces or coating.
FILTER CLEANING OPERATION Filter cleaning is performed after the power is turned on (after the plug-in or after the circuit breaker is switched on after power failure) • This is for filter cleaning operation check.
TROUBLESHOOTING (continued) FILTER CLEANING OPERATION (continued) • Filter may not be cleaned evenly depending on the environment in which the air conditioner is used. To solve this problem, clean the micro mesh stainless filter. Micro mesh stainless filter is still dirty • Depending on dust amount, the micro mesh stainless filter may not be completely cleaned by manual filter cleaning operation performed at your preferred time while filter cleaning operation is prohibited.

TROUBLESHOOTING (continued) THE FOLLOWING CASES DOES NOT INDICATE MALFUNCTION Odors Except for anti-mold wasabi cassette, no smell-generating material or substance is used for air conditioner. This is due to the smell or odor, such as cigarette, cosmetics and food, present in the room that is sucked in and then blown out by the air conditioner. In heating operation, (OPERATION) indicator lit and dim repeatedly Indicates preheating or defrosting operation is underway.
TEMPORARY OPERATION Press the temporary switch to start temporary operation if the remote controller cannot function due to dead batteries. Unplug the power plug when running the temporary operation. (Or turn off the circuit breaker.) 2 Plug in the power plug again. (Or turn on the circuit breaker.) 3 Automatic operation starts when the temporary switch is pressed.
REGULAR INSPECTION PLEASE CHECK THE FOLLOWING POINTS EVERY EITHER HALF YEARLY OR YEARLY. CONTACT YOUR SALES AGENT SHOULD YOU NEED ANY HELP. Is the plug plugged into the socket firmly? WARNING If the earth line is disconnected or faulty, unit failure or electric shock hazard may result. • If the plug have dust or dirt, please clean it before plug in.
