Friedrich 2009, 2008 service manual Make sure the wiring is adequate for your unit

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 manufac- turer. 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.

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.
