10. Cleaning the Indoor Unit Heat Exchanger
When dust adheres to the heat exchanger after the unit has been used for a long time, reducing the efficiency of heat exchange, and resulting in deterioration of cooling
performance.
Please ask your dealer how to arrange the clean.
11. When the Unit is to be Out of Use for a Long Time
<When the Unit is to be Out of Use for a Long Time>

Check the following (1) - (4), then turn the power supply on.
(1) Clean and fit the filter.
(2) Check that the inlets and outlets on the indoor and outdoor units are not
blocked.
(3) Check that the earth wire is connected. The earth wire may be connected
with the indoor unit as well in some cases.
Caution:
Do not connect the earth wire to gas pipes, water pipes, lightning rods, or
telephone earth wires. If earthing work is not conducted carefully it may
result in electric shock, smoke, flame, or mis-operation due to electrical
noise. Please ask your dealer before beginning earthing work.
(4) Check the drain hose to make sure there are not problems such as a bend,
raised end, or blockage.
(5) Turn the power supply on before 12 hours or more.
