" Cleaning the drain pan
CAUTION
• 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, benzine, 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.
Check
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 service shop if this is the case.
" Before a long idle period
1. Operate the "FAN only" for several hours on a fine day to dry out the inside.
2. After operation stops, turn off the breaker for the room air conditioner.
3. Clean the air filters and set them again.
4. Take out batteries from the remote control.
System Configuration
• 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.
• Press "MODE selector button" and select "FAN" operation.
• Press "ON/OFF button" and start operation.
• 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.
