CONTROLS
All controls for the Friedrich electronic air cleaner are located on the top of the unit and are
accessible through an opening in the top cover. The controls are: OFF, HI, MED and LOW.
An indicator lamp lights when the cleaner is on and operating normally.
Generally, HIGH fan speed is used in extreme conditions for rapid cleaning; such as during
or after a party where there were many smokers; or for larger areas to circulate the clean
air in all areas of the room. MEDIUM and LOW settings are usually adequate to maintain a
clean air environment.
At initial start-up, the indicator lamp may fl icker on and off and is not cause for alarm.
Should the lamp completely fail to come on, review the "BEFORE OPERATING" and
"TROUBLESHOOTING" sections.
During initial use, “snapping” sounds may be heard. This is normal, and the unit may continue
to make these noises during the fi rst few days of operation. After this initial break in period,
only an occasional "snap" will be heard, indicating the unit is cleaning your air. NOTE: As the
air cleaner’s electronic cell becomes dirty, it will "snap" more frequently. When this occurs,
you should wash the cell.
The best location for the air cleaner is a place closest to the source of tobacco smoke, dust
or other indoor contaminants.
Position the unit so that the airfl ow around the intake and discharge grilles is not blocked.
For best results, do not place the intake grille (rear) closer than eight (8) inches from a wall.
Provide a clear, unobstructed path for the discharge air. The farther the discharge air travels,
the greater the effectiveness of the air cleaner. For greater comfort, position the air cleaner
so that the discharge air does not cause uncomfortable drafts.
To use a room air cleaner most effectively in rooms that share an open doorway or archway,
position the unit near the common opening and direct the airfl ow into the adjacent room to
promote good air circulation.
ECONOMICAL CLEAN AIR
The Friedrich electronic air cleaner costs no more to operate than a standard household light
bulb. The benefi ts from clean air far outweigh the low operating costs of continuous cleaning.
Remember, the more you operate your electronic air cleaner, the cleaner your air will be.
IMPORTANT PRECAUTIONS
The collector plates of the electronic cell and the pre-fi lter can become extremely dirty. With
an excessive amount of contamination buildup on the collector plates and the pre-fi lter, the
electronic air cleaner’s effi ciency decreases. Also, as dirt builds up on the ionizing wires, the
charging process becomes less effi cient.
To prevent this loss of effi ciency, the electronic cell and pre-fi lter must be cleaned regularly.
How often will depend on actual usage. Cleaning will be more frequent if the air cleaner is
operated continuously or under severe conditions.
Turn off and unplug air cleaner before opening top cover to remove electronic cell and pre-
fi lter for cleaning. Always be careful when handling the electronic cell. Sharp edges and
wires are capable of infl icting wounds. Care should also be taken when cleaning because
of extremely hot water and potentially harmful effects of detergents on your skin.
