User Manual Frigidaire FFRH2522Q2 25,000 BTU Window-Mounted Room Air Conditioner

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.

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.

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.

When this feature is on, the electronic air purifier is energized to remove pollen and impurities from the air. To cancel this feature, press the Clean Air button.

BTU stands for British Thermal Unit and is the rating used for air conditioners. A BTU is defined by the quantity of heat required to raise the temperature of one pound of water one degrees Fahrenheit.
The higher the BTU, the larger space the room air conditioner will cool. Use this helpful guide below to decide which BTU is right for your area:
5k BTU: 150 Sq. Ft.
10k BTU: 450 Sq. Ft.
15k BTU: 850 Sq. Ft.
22k BTU: 1,300 Sq. Ft.
28k BTU: 1,900 Sq. Ft.

When this mode is enabled, the selected temperature will increase by 2 °F 30 minutes after the mode is selected.

The temperature will then increase by another 2 °F after an additional 30 minutes. This new temperature will be maintained for 7 hours before returning to the originally selected temperature.

This ends the “Sleep” mode and the unit will continue to operate as originally programmed. You may also cancel sleep mode at any time by again pressing the sleep button.
