How to operate the Friedrich room air conditioner (QuietMaster Programmable)

To start unit

1If your air conditioner is installed and plugged into a proper re- ceptacle, it is ready to go. Touch Power button once. The unit will automatically be in Cool mode with the temperature set at 75°F (24°C) and the fan speed at F1, the sleep setting. There is a 3- minute delay before the compressor will turn on. (See "Automatic Component Protection" on this page).

2Should the Check Filter light turn on when you rst turn on the unit, touch Check Filter to turn off the light. Check Filter light will come on after 250 hours of use. Clean filter.

Touch Check Filter to reset.

To set mode of operation

3When you rst turn on the unit, it will be in the Cool mode (light on), with constant fan.

4Touch MoneySaver® (light on) to activate the MoneySaver® feature. This cycles the fan with the compressor so that the fan does not run all the time. This saves energy and improves dehumidication. (MoneySaver® will also run the fan to sample the return air tempera- ture if the off cycle is too long). Or you may prefer constant fan for more air movement. To return to constant fan, touch Cool.

5Touch Fan Only (light on) if you want only the fan to run. You may want to use this feature in conjunction with the Fresh Air / Exhaust lever to bring outside air into a room, or to exhaust stale air. (See page 7, "Fresh Air and Exhaust Control" for more information.)

To adjust temperature [60°F (16°C) to 90°F (32°C)]

6COOLER – Touch and hold until the display shows the desired room temperature.

7WARMER – Touch and hold until the display shows the desired room temperature.

8FAHRENHEIT / CELSIUS – Touch ºF / ºC to show the temperature in Celsius, touch again to show Fahrenheit.

To adjust fan speed

9Touch 1-4 Speed to see current setting. Touch again to change speed. F1 is the lowest setting (SLEEP SETTING), F2 is low speed (LOW), F3 is medium speed (MED), F4 is high speed (HIGH).

To activate smart fan

10Touch Smart Fan (light on). Smart Fan will adjust the fan speed automatically to maintain the desired comfort level. For example, if the outside doors in your home are open for an extended period of time, or more people enter a room, Smart Fan may adjust to a higher fan speed to compensate for the increased heat load. This keeps you from having to adjust the fan speed on your own. Smart Fan cannot be activated in the Fan Only mode.

To deactivate smart fan

11 Touch 1-4 Speed, and select your desired fan speed.
