Frequently Asked Questions - AC 902 LERAN

How do I install the AC 902 air conditioner?

Place the unit near a window and attach the exhaust hose to the back. Extend the window kit to fit your window opening and secure the hose. Plug in and adjust settings via remote or control panel.

Can I use the air conditioner without the exhaust hose?

No, the exhaust hose is required to expel hot air. Without it, the unit will not cool properly and may overheat.

How often should I clean the filter?

Clean the washable filter every two weeks under normal use. More frequently in dusty environments. Slide out the filter, rinse with water, dry thoroughly and reinsert.

What does the 'Fan' mode do?

Fan mode circulates air without cooling. Use it to improve air circulation or when cooling is not needed. The compressor does not run, saving energy.

How do I drain condensate water?

The unit has a self-evaporative system, but in humid conditions, water may collect. Use the continuous drain hose (not included) by attaching it to the rear drain outlet. Alternatively, manually empty the internal tank when the 'Full' light appears.

Why is the air conditioner not cooling enough?

Check if the filter is clean, the exhaust hose is properly sealed, and the window kit is secure. Ensure the room size matches the cooling capacity (max ~20 m²). Also, avoid direct sunlight on the unit.

Can I use an extension cord?

It is not recommended. If necessary, use a heavy-duty extension cord rated for at least 15 amps and keep it as short as possible to avoid voltage drop.

How do I set the timer?

Press the 'Timer' button on the remote or control panel. Use '+' or '-' to set the desired hours (1-24). The unit will turn on or off after the set time.

What does the 'Swing' button do?

The 'Swing' button activates the vertical louver oscillation to distribute air evenly across the room. Press again to stop at a desired position.

Is the refrigerant R290 flammable?

Yes, R290 (propane) is flammable. The unit is designed with safety measures. Do not puncture the refrigerant circuit and keep away from ignition sources. Dispose of the unit properly.
