SiBE12-713 Instruction
Operation Manual 173
Cleaning the drain pan
•
Clean the drain pan periodically, or drain piping may be clogged with dust and may result in water leakage.
Ask your DAIKIN dealer to clean them.
•
Prepare a cover locally to prevent any dust in the air around the indoor unit from getting in the drain pan, if
there is a great deal of dust present.
CAUTION
Check
Before a long idle period
1. Operate the “FAN only” for several hours on a fine day to dry out the inside.
• Press “MODE selector button” and select “FAN” operation.
• Press “ON/OFF button” and start operation.
2. Clean the air filters and set them again.
3. Take out batteries from the remote controller.
4. Turn OFF the breaker for the room air conditioner.
• When a multi outdoor unit is connected, make sure the heating operation is not used at the
other room before you use the fan operation.
• Do not operate the air conditioner without filters, this to avoid dust accumulation inside the
unit.
• Do not remove the air filter except when cleaning.
Unnecessary handling may damage the filter.
•
Do not use gasoline, benzene, thinner, polishing powder, liquid insecticide, It may cause discoloring or
warping.
•
Do not let the indoor unit get wet. It may cause an electric shock or a fire.
• Operation with dusty air filters lowers the cooling and heating capacity and wastes energy.
• The suction grille is option.
• Do not use water or air of 50˚C or higher for cleaning air filters and outside panels.
• Ask your DAIKIN dealer how to clean it.
Check that the base, stand and other fittings of the outdoor unit are not decayed or corroded.
Check that nothing blocks the air inlets and the outlets of the indoor unit and the outdoor unit.
Check that the drain comes smoothly out of the drain hose during COOL or DRY operation.
•
If no drain water is seen, water may be leaking from the indoor unit. Stop operation and consult the ser-
vice shop if this is the case.
