Frequently Asked Questions - Avanti SRK13YSA-W MITSUBISHI

How do I clean the air filters?

Turn off the unit and disconnect power. Open the air inlet panel, remove the filters, and clean them every two weeks using a vacuum or warm water (approx. 30°C). Dry thoroughly before reinstalling. Do not use hot water or solvents.

What is SELF CLEAN operation?

SELF CLEAN operation runs the indoor unit fan for about two hours after COOL or DRY mode to remove moisture and inhibit mold and bacteria growth. Press the MENU button and select SELF CLEAN. The unit will stop automatically.

How do I set the ON TIMER?

Press the ON TIMER button until the display blinks. Use the ▲ or ▼ button to set the desired time, then press SET. The timer light will turn on. Operation starts 5–60 minutes before the set time for optimal comfort.

Why is the remote control not working?

Check if batteries are exhausted (replace with new R03/AAA batteries). Ensure there are no obstructions between the remote and the unit, and that the signal receiver is not exposed to direct sunlight. Press the ACL switch after battery replacement.

What does the CHILD LOCK function do?

CHILD LOCK locks the remote control buttons to prevent accidental operation. Press and hold the SET button for 3 seconds to enable or disable it. When active, only the ON/OFF button works.

How do I use the WEEKLY TIMER?

Press the WEEKLY button to enable it. Up to 4 timer programs per day can be set (ON TIMER/OFF TIMER) for each day of the week. Use the PROGRAM button to access settings. Point the remote at the unit and press PROGRAM to send settings.

What is the difference between HIGH POWER and ECO modes?

HIGH POWER runs the unit at maximum capacity for 15 minutes for rapid cooling. ECO mode sets the temperature 1.5°C higher than the setpoint to save energy. Both can be toggled with the HI/ECO button.

Why does the indoor unit make a gurgling sound?

A slight gurgling sound is normal and caused by refrigerant flowing through the system. If you hear unusual noises, contact your dealer.

What should I do if the unit stops cooling?

Check if the thermostat is set correctly, the air filter is clean, doors and windows are closed, and there is no direct sunlight or heat source. Also ensure the outdoor unit is not blocked. If issues persist, contact your dealer.

How do I replace the air-cleaning filters?

Open the inlet panel and remove the standard air filters. Then remove the filter holders containing the natural enzyme and photocatalytic washable deodorizing filters. Clean or replace them as needed (natural enzyme filter annually). Reinstall the holders and standard filters.

1. Open the air inlet panel and remove the air filters. Page 27
2. Remove the filter holders, with the air-cleaning filter installed in the holders, from the air-conditioner.

3. Remove the natural enzyme filter from filter holder and inspect the filter. Use a vacuum cleaner to remove any dust or dirt from the natural enzyme filter. Replace the natural enzyme filter if it cannot be cleaned or if it has been for about 1 year. (The natural enzyme filter should be replaced after about 1 year of use. However, the actual replacement period may vary depending on the conditions in which the filter is used.)
   Remove the photocatalytic washable deodorizing filter (orange) from the filter holder and inspect the filter. Periodically, remove any dust or dirt from the photocatalytic washable deodorizing filter. If the photocatalytic washable deodorizing filter is particularly dirty, it may be washed with water. However, the filter is fragile so be sure to wash it installed in the filter holder to avoid damaging it. After washing the filter, place it in sunlight to dry. Placing the filter in sunlight restores the deodorizing effect.
   (Do not dispose of the filter holders. They are reusable.)
