Power Cord with Arc Detection Device
The power cord supplied with this air conditioner is equipped with an Arc Detection Device designed to shut off power to the unit when it senses an arc fault condition. An arc fault is an unintentional electrical discharge that occurs when electrical products or wires are damaged, aged, or improperly used. An arc fault can be potentially hazardous if left undetected.

WARNING

• Do not use as an on/off switch
• Do not use outdoors
• Do not push furniture against or place furniture on the electrical cord. This can trip the test switch and/or damage the cord and become a potential condition for arcing
• Do not attempt to repair the cord. If the cord requires replacement, call an authorized servicer.
• The Arc Detection Device is not a Ground Fault Interrupter and should not be used as such
• The Arc Detection Device contains an electronic circuit board and should not be submerged or exposed to water spray

Resetting

Installing the rear grille into a new wall sleeve

A new Fedders Wall sleeve (sold separately) will ensure the best fit and performance of your new through-the-wall air conditioner. See your local Fedders dealer or distributor about purchasing wall sleeve model A70052. To locate a dealer in your area, call 1-800-332-6658.

Follow the installation instructions that are included with your new wall sleeve.

If you have a new Fedders wall sleeve already installed in the room with front and rear covers in place, you may complete the installation by attaching the rear grille.

To Install the rear grille into a new Fedders wall sleeve

1. Remove the front and back covers of the new wall sleeve. Save the covers for future use to seal the wall sleeve if the air conditioner is removed.
2. Clean out any debris from inside the wall sleeve, making sure the inside is clean and that the drain holes are completely open.
3. Insert the new grille into the wall sleeve. (Fig. 1)
4. Secure the grille to the sleeve with six (6) screws (provided) through the holes in the grille and into the sleeve. (Fig. 2)

Warning: Install the new grille that came with your unit or new Fedders sleeve. If this rear grille is not installed in the wall sleeve, your unit will not operate correctly and the warranty will be void.

Both the air conditioner and the wall sleeve come with the rear grille. If you have ordered both items, you may discard the extra grille.

Installing the rear grille into an existing wall sleeve:

1. Measure the dimensions of your existing wall sleeve. (Fig. 3)
2. Locate your wall sleeve in the wall sleeve identification chart below.

If you have any questions or if your sleeve is not listed please call 217-347-6459 or email customerservice@fedders.com . You must install the new grille included with your air conditioner. Failure to do so could damage the unit and will void the warranty.
