Frequently Asked Questions - AC 966 IV LERAN

How do I set the timer on the AC 966 IV?

Press the TIMER button on the remote. Use the +/- buttons to set the desired time (0-24 hours). The unit will turn on/off accordingly. Confirm with the SET button.

What does the ECO mode do?

ECO mode reduces power consumption by cycling the compressor: it operates at 75%, then 55%, then 35% of its capacity. This saves energy while maintaining comfort.

How often should I clean the air filter?

Clean the filter every two weeks under normal use. Remove the filter from the indoor unit, wash with mild detergent, let it dry completely, and reinstall.

How do I activate the child lock?

Press and hold the LOCK button (often a star icon) on the remote for 3 seconds. The display will show a lock symbol. To unlock, repeat the process.

What does the cleaning mode do?

Cleaning mode runs the fan to dry the evaporator coil, preventing mold and mildew. Activate it from the remote or unit panel when the unit is off.

Why is my air conditioner not cooling?

Check the filter for blockage, ensure set temperature is below room temp, and that the outdoor unit has clearance. If problem persists, contact a technician.

Can I use an extension cord?

No. Plug the unit directly into a dedicated wall outlet (220-240V). Extension cords may overheat and cause fire.

How do I reset the remote control?

Remove the batteries, wait 30 seconds, reinsert them. If the remote still fails, replace batteries with new ones (2x AAA).

What is the refrigerant type?

The unit uses R32 refrigerant, which is environmentally friendly and has lower global warming potential than older refrigerants.

Where can I find spare parts?

Contact the LERAN dealer or authorized service center. Common parts like filters and remote controls are available online. Use only genuine parts.
