For the best cooling performance and highest energy efficiency
Keep the filter clean
Make sure that your air conditioner is always in top performing condition by cleaning the filter regularly.
Provide good air flow
Make sure the airflow to and from the unit is clear. Your air conditioner puts the conditioned air out at the top of the unit, and takes in unconditioned air at the bottom. Airflow is critical to good operation. It is just as important on the outside of the building that the airflow around the unit exterior is not blocked.
Unit placement
If your air conditioner can be placed in a window or wall that is shaded by a tree or another building, the unit will operate even more efficiently. Using drapes or blinds on the sunny side of the dwelling will also add to your unit’s efficiency.
Insulation
Good insulation will be a big help in maintaining desirable comfort levels. Doors should have weather stripping. Be sure to caulk around doors and windows.
Proper installation of seal gasket
Make sure the seal gasket has been installed properly to minimize noise and improve efficiency. If the seal gasket has not been installed, please refer to Step 14 of the installation instructions.
Also, if you switch from Cool mode to Fan Only, and switch back to COOL mode, there is a three minute delay before the compressor comes back on.

How to operate the Friedrich room air conditioner (QuietMaster Programmable)
To start unit
1If your air conditioner is installed and plugged into a proper receptacle, 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 yourst 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 yourst 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 temperature 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).

How to operate the Friedrich room air conditioner
(QuietMaster / Twintemp models)
To start unit
If your air conditioner is installed and plugged into a properly grounded receptacle, it is ready to operate.
Mode control (QuietMaster)
The upper dial (Figure 7) allows you to select cooling at four different speeds, as well as Fan Only (Models SL28 and SL36 only have three cooling speeds.).
Off - to turn the unit off.
High Cool - for quick cooling.
Medium Cool - to maintain a desired temperature. Low Cool - when cooling demand is low.
Sleep Setting - for nighttime use, or when cooling demand is low. Fan Only - to circulate air in the room without the compressor coming on.
The Fan Only setting can also be used with the Exhaust air setting to remove stale air or smoke from the room; or it can be used with the Fresh Air setting to bring outside air into the room. This is especially useful in the spring and fall when cooling may not be necessary. The Fresh Air and Exhaust controls are in the upper air discharge area. The center position of this control is the normal, or closed position, which recirculates air for maximum performance in the cooling mode.
Mode control (Twintemp)
This dial allows you to select cooling or heating at three different speeds, |
Figure 7 |
as well as Fan Only (Figure 8). |
|
Off - to turn the unit off. |
|
High Cool or High Heat - for quick response. |
|
Medium Cool or Medium Heat - to maintain a desired temperature. |
|
Low Cool or Low Heat - for nighttime use, or when demand is low. |
|
Fan Only - to circulate air in the room without the compressor coming on. |
|
The Fan Only setting can also be used with the Exhaust air setting to |
|
remove stale air or smoke from the room, or it can be used with the Fresh |
|
Air setting to bring outside air into the room, especially in the spring and |
|
fall when cooling isn’t necessary. |
|
The Fresh Air and Exhaust controls are in the upper air discharge area. |
|
The center position of this control is the normal, or closed position, which |
|
recirculates air for maximum performance in the cooling mode. |
|
NOTE: You may notice an odor when first activating the heat when the |
|
electric heat element comes on. This is due to dust burning off that may |
|
have gathered on the coil during the summer. This is normal. |
|
Temperature control
The bottom dial on the control panel is the thermostat. Turn it clockwise for cooler temperature and counterclockwise for warmer.
Money Saver® switch
This rocker switch can be depressed to either Yes or No. In the Yes position you will get the most economical operation. Both the fan and compressor will cycle on and off together, maintaining the selected temperature at a more constant level and reducing the humidity more efficiently in the cooling mode. This control will only operate when the unit is in cooling or heating mode. In the No position, the fan will run constantly as long as the unit is
in the cooling or heating mode. |

1.Activate Error Code Mode by pressing the “TIMER ON/ OFF” button on XQ models. LED for the “TIMER ON/ OFF” will flash 1 bps while Error Code Mode is active. Pressing the “TEMP/HR ” button will display 00. Consecutive presses will scroll through all error codes logged. Press the “TEMP/HR ” button to see the reverse order of all error codes logged. When the end of logged error codes is reached the temperature set point will appear.
Activate Error Code Mode by pressing at the same time the “A/C START” button and the “ON/OFF” button on QME models. LED for the “TIMER ON/OFF” will flash 1 bps while Error Code Mode is active. Pressing the “TEMP ” button will display 00. Consecutive presses will scroll through all error codes logged. Press the “TEMP ” button to see the reverse order of all error codes logged. When the end of logged error codes is reached the temperature set point will appear.
IMPORTANT: ErrorCodesareclearedfromthelog by exiting from Error Code Mode. To exit on XQ models, press Timer On/Off button. To exit QME models, press A/C Start and On/Off buttons. Or unplug unit to exit Error Code Mode. Plug unit in after 5 seconds to resume normal operation of unit.
TESTING THE ELECTRONIC CONTROL ERROR CODE LISTINGS
E1 SHORT CYCLE SITUATION: Defined as (compressor powered on before the three minute time delay ten times in one hour. Investigate and correct short cycling problem.
E2 KEYBOARD STUCK ERROR: If key button(s) are pressed continuously for twenty seconds or more. If MODE key is stuck, unit will default to cool. Exit Error Code Mode to see if error “E2” is no longer displayed and unit is functioning. Replace board if “E2” still displays after exiting
Error Code Mode.
E3 FROST PROBE OPEN: Normal operation is allowed. Ohm frost probe. Replace probe if ohm value not read. If ohm value is present replace board.
E4 FROST PROBE SHORT: Normal operation allowed. Replace probe.
E5 INDOOR PROBE OPEN: Control assumes indoor ambient temperature is 90 degree F and unit will operate. Ohm indoor probe. Replace probe if ohm value not read.
E6 INDOOR PROBE SHORT: Control assumes ambient temperature is 90 degree F and unit will operate. Replace probe.
NOTE: All Error Code displays for Frost & Indoor Probe will allow unit to operate. Unit may or will ice up if faulty components not replaced.
FROST PROBE SENSOR: disables compressor at 35 degrees F.
INDOOR PROBE SENSOR: Control range is 60 degrees F to 90 degrees F +/- 2 degrees F.
Indoor temperature will be displayed by pressing: (QME units) The Fan Speed button and the Temperature button.
(XQ units) The Fan Speed button and the “TEMP “ button.
The indoor temperature will be displayed for 10 seconds. The display will change back to the Set Point temperature by pressing any key button except for the On/Off button. The indoor temperature can be viewed in all modes, including test mode.
Check Filter: The Check Filter indicator turns on after the fan motor has been operating for 250 hours. The Check Filter indicator is reset by pressing the Check Filter button one time only. Power failures will not reset the 250 hour timer. All time elapsed is stored in memory and resumes counting after power is restored.
Keep Alive: The electronic control has a memory to retain all functions and status as set up by the user in the event of a power failure. Once power is restored to the unit there is a two second delay before the fan comes on and approximately three minutes delay before the compressor is activated, providing that the mode was set for cooling and the set point temperature has not been met in the room.

TESTING THE ROTARY CONTROL SWITCHES
(Heat Pump & Electric Heat Models) (See Figure 12)
An e ight position control switch is used t o regulate the operation of thefan motor and compressor. The compressor can be operated with the fan operating at low, medium or high speed in the cooling or heating mode. The fan motor can also be operated independently on medium speed. See switch section as indicated on decorative control panel.
NOTE: Heat pump models with electric heat - in the heat position, heating element only will be energized when outdoor temperature is below the operating range of the heat pump.
