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

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 Table 1.

DO NOT use an extension cord.

The cord provided will carry the proper amount of electrical power to the unit; an extension cord may 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 certi¿ed 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 effective August 2004.

To test your power supply cord:

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

2.Press RESET (See Figure 1).

3.Press TEST, listen for click; the RESET button trips and pops out.

4.Press and release RESET (Listen for click; RESET button latches and remains in). The power cord is ready for use.

Note: The LCDI device is not intended to be used as an ON/OFF switch.

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

If the LCDI device fails to trip when tested or if the power supply cord is damaged, it must be replaced with a new power supply cord from the manufacturer. Contact our Technical Assistance Line at (800) 541-6645.To expedite service, please have your model 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 oulet.

 

 

Failure to follow these instructions can result in

 

 

death, fire, or electrical shock.

IT IS WORKING

PROPERLY!

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.

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 chassis seal gasket

Make sure the seal gasket has been installed properly to minimize noise and improve efficiency. If the chassis seal gasket has not been installed, please refer to Step 14 of the installation instructions.

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.

Kuhl Q Control Panel Operation

Let’s check out how to control your air conditioner. On the control panel, just above the POWER , is a liquid crystal display (LCD). All of the control panel function buttons and mode icons can be viewed in Figure 6.

Power On – Press the button to turn on the air conditioner. The power button illuminates to indicate that the power is on. The backlight on the power switch will automatically dim to 20% intensity after 15 seconds of inactivity. The remote control can also be used to turn power ON / OFF (See Remote Control).

Display – The display is a high ef¿ciency LCD with abuilt-inwhite backlight. The backlight has an automatic two (2) step dim function. After 15 seconds of inactivity, the display dims to 20% intensity. After an additional 120 seconds, the display switches off. Touching any button automatically changes the display to full brightness.

There are three control push buttons on each side of the display.
