Frequently Asked Questions - Energysilence 3500 Cool Compact Smart CECOTEC

How to install the window exhaust kit?

Attach the adapter plate to the open window, then connect the exhaust hose to the back of the unit. Ensure the hose is not bent to guarantee good airflow.

Can I use the unit without the exhaust hose?

No, the mobile air conditioner requires the hose to expel hot air outside. Without it, the unit will cool poorly and may overheat.

How to connect the unit to WiFi?

Download the Cecotec Smart app on your smartphone, create an account, then follow the instructions to pair the device. Make sure your 2.4 GHz network is enabled.

The water indicator is blinking, what should I do?

This indicates the condensate tank is full. Drain it manually or install a continuous drainage hose. The unit will stop automatically until the tank is emptied.

How often should I clean the filter?

Clean the filter every two weeks or more often if the air is dusty. Use a vacuum or wash it with lukewarm water and let it dry completely before reinstalling.

What is the maximum cooling area?

The unit is designed for rooms up to approximately 30 m² with standard ceiling height. Performance may vary depending on insulation and outdoor temperature.

Can I use the unit in ventilation only mode?

Yes, select 'ventilation' mode on the remote control or display. In this mode, the compressor does not operate and only the fan circulates air.

What should I do if the unit is not cooling enough?

Check that the filter is not clogged, the exhaust hose is not bent, and the window is properly sealed. Also ensure the target temperature is well below the room temperature.

The remote control is not working, what should I do?

Replace the batteries with new ones (type CR2025). Check that no obstacles block the infrared receiver on the unit. Try approaching within 5 meters.

How to activate the silent night mode?

Press the 'Night' or 'Silence' button on the remote control. This mode gradually reduces the fan speed and dims the display light for restful sleep.
