Push the lever to the "CLOSE" position to cool, heat or recirculate room air only. Pull the lever to the "OPEN" position to exhaust smoke or stale air from the room. This feature is best used in conjunction with the FAN ONLY position.

Air Direction

Inserting the Remote Control Batteries

The direction of air can be controlled by adjusting the horizontal and vertical louvers.

• HORIZONTAL AIR-DIRECTION CONTROL

The horizontal air direction is adjusted by moving the vertical louver. The lever for the vertical louver is located in the right and left side of the air discharge.

• VERTICAL AIR-DIRECTION CONTROL

The vertical air direction is adjusted by moving the horizontal louver.

1. Remove the cover from the back of the remote controller.

2. Insert two batteries.

• Be sure that the (+) and (

–

) directions are correct.

• Be sure that both batteries are new.

3. Reattach cover.

• Do not use rechargeable batteries. Make sure that both batteries are new.

• In order to prevent discharge, remove the batteries from the remote control if the air conditioner is not going to be used for an extended period of time Keep the remote control away from extremely hot or humid places. To maintain optimal operation of the remote control, the remote sensor should not be exposed to direct sunlight.

Operating Instrucitons

Air Filter Cleaning

The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in the filter will build up and block the airflow. This reduces the cooling capacity and can also cause an accumulation of frost on the cooling coils.

If the filter becomes torn or damaged you should replace it immediately. Replacement filters are available from your salesperson, dealer, and authorized customer service centers.

1. Open the inlet grille downward by grasping the top outside edges of the inlet grille and pulling it towards you.

2. Remove the air filter from the front grille assembly by pulling the air filter up slightly.

3. Wash the filter using lukewarm water and a mild detergent.

4. Gently shake all excess water from the filter. Make sure the filter is completely dry and replace the filter back into the unit.

How to Attach Front Grille to Cabinet

The front grille can be removed for cleaning or to check the model and serial numbers. For your safety, you should attach the front grille using the following procedures.

Care and Maintenance

1. Pull down front grille from the cabinet top.

2. Push front grille’s tips toward the cabinet in order to insert front grille’s tabs into the cabinet.

3. Open the inlet grille.

4. Tighten the screw through the front grille into the plate of control box.

5. Close inlet grille.

TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.

INSTALLATION REQUIREMENTS

If you use an existing wall sleeve, you should measure

its dimensions. Install the new air conditioner according to these installation instructions to achieve the best performance. All wall sleeves used to mount the new air conditioner must be in good structural condition and have a rear grille to securely attach the new air conditioner. (FIG. 1) Installing the FRIEDRICH USC sleeve ensures optimal performance of the new air conditioner. (FIG. 2)

ELECTRICAL SERVICE

Check your available electrical service. The power supply available must be the same as that shown on the unit nameplate (found on left side of cabinet).

All models are equipped with a 3-prong service plug to provide proper service and safe positive grounding. Do not change plug in any way. Do not use an adapter plug. If your present wall outlet does not match your plug, call a qualified electrician to make the necessary corrections. SAVE CARTON for storage and this OWNER'S MANUAL for future reference. The carton is the best way to store unit during winter or when not in use.

• Pick a location which will allow the conditioned air to blow into the area you want. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed.

ITEMS IN INSTALLATION HARDWARE

You may not need all parts in the kit. Discard unused parts

HOW TO INSTALL

Before installing the unit, identify the existing wall sleeve from the list below.

NOTE: All wall sleeves used to mount the new Air Conditioner must be in sound structural condition and have a rear grille that securely attaches to sleeve, or rear flange that serves as a stop for the Air Conditioner.

Remove old air conditioner from existing wall sleeve.

Clean the interior of an existing sleeve. (Do not disturb seals.)

Wall sleeve must be securely fastened in wall before installing the air conditioner. Use the nails or screws through sleeve into wall, if needed. Repaint sleeve if needed.

Prepare the wall sleeve for installation of the unit. If you plan to use your existing wall sleeve, and it is not FRIEDRICH, use procedure B or C below.

Install new unit into wall sleeve.

CAUTION: When installation is completed, replacement unit MUST have a rearward slope as shown. To achieve 1/4" slope, remove the backing from the 11-13/16" shim strips and attach them as shown below in Fig. 3. Place the higher portion of shim to the front of the rib on base of wall sleeve.
