Frequently Asked Questions - U798CH1 ROTEL
How to install the exhaust hose?
Screw the appropriate side of the hose onto the air exhaust outlet at the back of the unit by turning counterclockwise. Make sure the hose is not twisted and its length does not exceed 150 cm.
How to install the sealing frame in the window?
Open the window halfway, insert the sealing frame horizontally or vertically, then adjust its length to the window size by extending or shortening the two ends before securing it.
What does the 'FL' display on the screen mean?
The 'FL' code indicates that the condensation water tank is full. Drain the unit by unscrewing the water outlet cap at the back and collecting the water in a container. Once drained, the unit resumes normal operation.
How to clean the air conditioner filters?
Turn off and unplug the unit. Remove the evaporator filter frame by pulling it down and unscrew the 4 screws. For the condenser filter, gently pull the frame towards you. Wash the filters with warm water (about 40 °C) and a neutral detergent, rinse and dry in the shade before reinstalling.
What are the built-in safety functions?
The unit has several safety features: anti-freeze protection (stops if temperature too low in the hose), overflow protection (stops if tank is full), automatic defrost, and compressor protection (restarts after 3 minutes in case of power outage).
How to set the timer?
Press the TIMER button. When the symbol flashes, use the UP or DOWN buttons to set the desired time from 1 to 24 hours. The timer can be programmed for stop (unit on) or delayed start (unit off).
What are the available operating modes?
The air conditioner offers three modes: Air conditioning (cooling), Fan (air circulation without cooling), and Dehumidification (humidity reduction). Use the MODE button to switch between them.
Why is the unit not cooling enough?
Possible causes: ambient temperature too high, direct sunlight, door or window open, dirty filter, blocked air inlet/outlet, or set temperature too high. Recommendations: close curtains, doors and windows, clean the filter, and remove obstacles.
How to store the air conditioner at the end of the season?
Drain any remaining water by tilting the unit backward. Run it in Fan mode for a few hours to dry the inside. Turn off, unplug, wrap the cord around the hooks, remove the exhaust hose, take out the remote control batteries, and cover the unit with a plastic tarp before storing in a dry place.
What to do if the remote control does not work?
Check the distance (max 8 m), point the remote at the sensor on the control panel, and replace the batteries if necessary (type CR2025 or similar). If the problem persists, contact a professional.
