Frequently Asked Questions - AC 903 BOSFOR
How do I install the BOSFOR AC 903 air conditioner?
Install the exhaust hose in the window using the included window kit. Ensure the hose is straight and not bent. Plug in the unit and select the desired mode.
How often should I clean the filter?
Clean the washable mesh filter every two weeks for optimal performance. Remove the filter, rinse with water, let it dry completely before reinstalling.
Why is the air conditioner not cooling?
Check if the filter is dirty. Ensure the exhaust hose is properly installed and not blocked. The room may be too large for the unit's cooling capacity (9000 BTU/h). Also verify the set temperature is lower than room temperature.
Do I need to drain water from the unit?
The AC 903 has a self-evaporative system that evaporates most condensate. In high humidity, you may need to drain water manually using the drain plug at the bottom.
Can I use an extension cord with this air conditioner?
It is not recommended. Use a dedicated outlet. If necessary, use a heavy-duty extension cord with a minimum 13A rating and keep it as short as possible.
What does the timer function do?
The 24-hour timer allows you to set the unit to turn on or off automatically. Press the timer button on the remote or control panel, then set the desired time.
How do I switch between cool, fan, and dehumidify modes?
Press the Mode button on the remote or control panel until the desired mode indicator lights up. Cool mode lowers temperature, fan mode circulates air, and dehumidify mode removes moisture.
The unit displays an error code. What should I do?
Refer to the user manual for error code definitions. Common codes indicate dirty filter, full water tank, or sensor issues. Turn off the unit, unplug it, wait 10 minutes, and restart.
Is the AC 903 suitable for large rooms?
The cooling capacity of 9000 BTU/h is suitable for rooms up to about 25 square meters (270 sq ft). For larger rooms, performance may be insufficient.
How do I reset the remote control?
Remove the batteries from the remote, wait 30 seconds, then reinsert them. Ensure batteries are fresh and correctly oriented. Point the remote directly at the unit.
