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 wall plug provided.
This insures proper grounding. If you have a two-prong receptacle you will need to have the circuit replaced
by a certified electrician with a grounded circuit that meets all national and local codes and ordinances. You
must use the three-prong plug furnished with the air conditioner.

For the Best Cooling Performance and Energy Efficiency
Keep the filter clean
Make sure that your air conditioner is always in top performing condition by cleaning the filter regularly.
Instructions for removing and cleaning the filter can be found on page 6.
Provide good airflow
Make sure that the airflow to and from the unit is clear. Your air conditioner puts the air out at the top of
the unit, and takes in 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 a 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.

The Front Grille and Inlet Grille may be wiped with a
cloth dampened in a mild detergent and lukewarm water
solution. (Fig. 2)
The cabinet may be washed with mild soap or detergent and
lukewarm water.
To ensure continued peak efficiency, the condenser
coils(outside of unit) should be checked periodically and
cleaned if clogged with soot or dirt from the atmosphere.
Consult a certified Friedrich service agent for more information.

pulling them off.(Fig.3)
2. Remove the screw securing the Front Grille.(Fig.3) The screw is
located behind the bottom temperature knob.
3. Push the grille up from the bottom and pull the top of the grille

NOTE: All supporting parts should be secured to firm wood, masonry, or metal.
1. This unit is designed for installation in standard double hung windows with actual opening widths of
22" to 36". The upper and lower sash must open sufficiently to allow a clear vertical opening of 13"
from the bottom of the sash to the window stool.
2.If storm window presents interference, fasten a 2" wide wood strip to the inner window sill across
the full width of the sill. The wood strip should be thick enough to raise the height of the window sill
so that the unit can be installed without interference by the storm window frame.
See Fig. 5-2. The top of the wood strip should be approximately 3/4" higher than the storm window
frame (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain
properly to the outside.
3. Install a second wood strip (approximately 6" long by 11/2" wide and same thickness as first strip) in
the center of the outer sill flush against the back off the inner sill. This will raise the Lbracket as
shown Fig. 5-2.
4. If the distance between STORM WINDOW FRAME and WOOD STRIP MOUNTED ON TOP OF
INNER SILL is more than 1", two of wood strips are not necessary.
