FUNCTIONAL DESCRIPTION
EXTENSION CORDS
Use proper extension cords. Make
sure your extension cord is in good
condition and is a 3-wire extension cord which has a
3-prong grounding type plug and matching
receptacle which will accept the machine’s plug.
When using an extension cord, be sure to use one
heavy enough to carry the current of the machine.
An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. Fig. C
shows the correct gauge to use depending on the
cord length. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
FOREWORD
Model 50-871 3 Speed Digital Ambient Air Cleaner is specifically designed to quietly circulate and filter non-
metallic dust which is generated throughout the work area. The Air Cleaner is furnished with two filters: an outer
filter which filters particles that are five microns and larger, and a secondary disposable filter that captures 91%
of the dust particles that are one micron and larger (one micron = one millionth of a meter). Because breathing
microscopic particles can be a potential health hazard, filtering microscopic dust particles offers a cleaner and
safer environment. This Air Cleaner will filter the air in a room measuring 20’ x 20’ x 8’ either 13, 16, or 18 times an
hour, depending on the setting. If desired, multiple units can be used to filter larger areas. An occasional cleaning
and/or replacement of filters is the only required maintenance.
