WARNING

ELECTRIC SHOCK HAZARD

Turn off electric power before service or installation.

All electrical connections and wiring MUST be installedbyaqualifiedelectricianandconformto the National Electrical Code and all local codes which have jurisdiction.

Failure to do so can result in personal injury or death.

 

NOTICE

 

 

FIRE HAZARD

 

 

Not following the above WARNING could result in fire or

 

 

electically unsafe conditions which could cause moderate

 

 

or serious property damage.

 

 

Read, understand and follow the above warning.

 

 

 

 

Wire Size

Use ONLY wiring size recommended for single outlet branch circuit.

Fuse/Circuit Breaker

Use ONLY the correct HACR type and size fuse/circuit breaker. Read electrical ratings on unit’s

 

rating plate. Proper circuit protection is the responsibiity of the homeowner.

Grounding

Unit MUST be grounded from branch circuit through service cord to unit, or through separate

 

ground wire provided on permanently connected units. Be sure that branch circuit or general

 

purpose outlet is grounded.

Receptacle

The field supplied outlet must match plug on service cord and be within reach of service cord.

 

Do NOT alter the service cord or plug. Do NOT use an extension cord. Refer to the table above

 

for proper receptacle and fuse type.

Theconsumer-throughtheAHAMRoomAirConditionerCertificationProgram-can be certain that the AHAM Certification Seal accurately states the unit’s cooling and heating capacity rating, the amperes and the energy efficiency ratio.

*HACR: Heating Air Conditioning and Refrigeration

10

WARNING: Before operating your unit

Make sure the wiring is adequate for your unit.

If you have fuses, they should be of the time delay type. Before you install or relocate this unit, be sure that the amperage rating of the circuit breaker or time delay fuse does not exceed the amp rating listed in Figure 1.

DO NOT use an extension cord.

The cord provided will carry the proper amount of electrical power to the unit; an extension cord will not.

Make sure that the receptacle is compatible with the air conditioner cord plug provided.

This insures proper grounding. If you have a two prong receptacle you will need to have it replaced with a grounded receptacle by a certified electrician. The grounded receptacle should meet all national and local codes and ordinances. Under no circumstances should you remove the ground prong from the plug. You must use the three prong plug furnished with the air conditioner.

Test the power cord

All Friedrich room air conditioners are shipped from the factory with a Leakage Current Detection Interrupter (LCDI) equipped power cord. The LCDI device meets the UL and NEC requirements for cord connected air conditioners.

To test your power supply cord:

1.Plug power supply cord into a grounded 3 prong outlet.

2.Press RESET (See Figure 2).

3.Press TEST (listen for click; Reset button trips and pops out).

4.Press and release RESET (listen for click; Reset button latches and remains in). The power supply cord is ready for operation.

NOTE: LCDI device is not intended to be used as a switch.

Once plugged in the unit will operate normally without the need to reset the LCDI device.

If the device fails to trip when tested or if the power supply cord is damaged it must be replaced with a new supply cord from the manufacturer. We recommend you contact our Technical Assistance Line at (800) 541-6645 ext. 845. To expedite service, please have your model and serial number available.

WARNING

ELECTRICAL SHOCK HAZARD

Make sure your electrical receptacle has the same configuration as your air conditioner’s plug. If different, consult a Licensed Electrician.

Do not use plug adapters.

Do not use an extension cord.

Do not remove ground prong.

Always plug into a grounded 3 prong outlet. Failure to follow these instructions can result in electrical shock, serious injury or death.

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.

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.
