INTRODUCTION
Model No. 50-860 Delta Air Cleaner is specifically designed to quietly circulate and filter non-met allic dust
which is generated throughout the work area. The Air Cleaner is furnished with two filters: a disposable outer
filter which filters out 98% of p articles five microns in size; and the secondary filter will capture 85% of dust
particles of one micron in size (one micron = one millionth of a meter). Breathing microscopic p articles can
be a potential health hazard; therefore, filtering out microscopic dust p articles of the mentioned sizes will of fer
a cleaner and safer environment. This Air Cleaner will filter the air in a room measuring 20 x 20 x 8 sixteen
times an hour. If desired, multiple unit s can be used to filter larger areas. The Air Cleaner is virtually maintenance free; an occasional cleaning and/or replacement of filters is the only maintenance required.

GROUNDING MEANS
ADAPTER
In the event of a malfunction or breakdown, grounding
provides a p ath of least resist ance for electric current to
reduce the risk of electric shock. This tool is equipped
with an electric cord having an equipment-grounding con ductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly inst alled and
grounded in accordance with all local codes and ordi nances.
Do not modify the plug provided - if it will not fit the out let, have the proper outlet inst alled by a qualified electri cian.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor
with insulation having an outer surface that is green with
or without yellow stripes is the equipment-grounding conductor. If rep air or replacement of the electric cord or plug
is necessary, do not connect the equipment grounding
conductor to a live terminal.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely under stood, or if in doubt as to whether the tool is properly
grounded.
GROUNDING INSTRUCTIONS
CAUTION: THIS TO O L MUST BE GROUNDED WHILE IN USE
TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and 3-hole recept acles that accept
the tool’s plug, as shown in Fig. 8.
R e p air or replace damaged or worn cord immediately.
This tool is intended for use on a circuit that has an out let and a plug that looks like the one shown in Fig. 8.
A temporary adapter, which looks like the adapter illus trated in Fig. 9, may be used to connect this plug to a
2-pole recept acle, as shown in Fig. 9, if a properly
grounded outlet is not available. The temporary adapter
should be used only until a properly grounded outlet can
be inst alled by a qualified electrician. THIS ADAPTER IS
NOT APPLICABLE IN CANADA. The green-colored
rigid ear , lug, and the like, extending from the adapter
must be connected to a permanent ground, such as a
properly grounded outlet box, as shown in Fig. 9.
CAUTION: IN A L L CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.
IF YOU ARE NOT SURE HAVE A CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.

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 a 3-pole
recept acle which will accept the tool s plug. When using
an extension cord, be sure to use one heavy enough to
carry the current of the air cleaner . An undersized cord
will cause a drop in line volt age, resulting in loss of power
and overheating. Fig. 10 shows the correct gage to use
depending on the cord length. If in doubt, use the next
heavier gage. The smaller the gage number , the heavier
the cord.
