User Manual Frigidaire FFTA1233S2 12,000 BTU Built-In Room Air Conditioner

For most air conditioners, the filter can be found by opening the front panel. Since it’s a reusable filter, you can simply remove and clean using warm, soapy water. After cleaning, allow the filter to dry thoroughly before replacing it. You may also vacuum the air filter to remove excess dirt and particles.
For more details regarding the air filter in your specific model, please reference your Use & Care manual.

Proper air flow into the air conditioner is essential for performance and safe operation. Under no circumstances should you block or cover any exterior or interior vents of the unit.

Room Air Conditioners, during operation, may make noise. It is normal to hear ‘high pitch chatter’ a sound of rushing air, gurgle/hiss, pinging or swishing and vibration. These are all normal.
For more definition of noises, please refer to your product’s Use and Care guide.

If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to its original carton.
NOTE: To prevent rust or electrical connections from being damaged, store air conditioner in an upright position and a dry place.
