Whirlpool ACM122XR0 User Manual

Turn the THERMOSTAT control to a mid-setting. Adjust the air 
conditioner's performance by turning the Thermostat control 
clockwise for maximum cooling. For less cooling, turn the 
THERMOSTAT control counterclockwise. Experiment to find the 
setting that suits you best.

Use the tabs to direct the air right or left (on some models). 
Rotate the whole cartridge to direct air up, down or straight 
ahead.

When your air conditioner is operating normally, you may hear 
sounds such as:

■

Droplets of water hitting the condenser, causing a pinging or 
clicking sound. The water droplets help cool the condenser.

■

Air movement from the fan.

■

Clicks from the thermostat cycle.

■

Vibrations or noise due to poor wall or window construction.

■

A high-pitched hum or pulsating noise caused by the modern 
high-efficiency compressor cycling on and off.

Your new air conditioner is designed to give you many years of 
dependable service. This section tells you how to clean and care 
for your air conditioner properly. Call your local authorized dealer 
for an annual checkup. Remember… the cost of this service call 
is your responsibility.

The air filter is removable for easy cleaning. A clean filter helps 
remove dust, lint, and other particles from the air and is important 
for best cooling and operating efficiency. Check the filter every 
2 weeks to see whether it needs cleaning. 

NOTE: Do not operate the air conditioner without the filter in 
place.

1. Turn off air conditioner.

2. Using indents in top of filter door, pull door down. Filter door 

is not removable.

3. Slide air filter up and out to remove from the filter door.

4. Use a vacuum cleaner to clean air filter. If air filter is very dirty, 

wash it in warm water with a mild detergent. Do not wash air 
filter in the dishwasher or use any chemical cleaners. Air dry 
filter completely before replacing to ensure maximum 
efficiency.

5. Slide air filter down into the filter door. Close filter door.

1. Turn off air conditioner.

2. Remove the air filter and clean it separately. See “Cleaning 

the Air Filter.”

3. Wipe the front panel with a soft, damp cloth. 

4. Air dry front panel completely.

Check once or twice a year for paint damage. This is very 
important, especially in areas near oceans or where rust is a 
problem. If needed, touch up with a good grade enamel paint.

NOTE: To reduce paint damage during the winter, install a heavy-
duty cover over air conditioner cabinet. For information on 
ordering a heavy-duty cover, see “Accessories.” 

Your air conditioner needs annual maintenance to help ensure 
steady, top performance throughout the year. Call your local 
authorized dealer to schedule an annual checkup. The expense 
of an annual inspection is your responsibility.
