Grounding Instructions
Electrical connections must be made by a qualified electrician in compliance with
all relevant codes. This machine must be properly grounded to help prevent electrical shock and
possible fatal injury.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in a 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 repair 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
understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension cords
that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.
Repair or replace a damaged or worn cord immediately.
115 Volt Operation
The Air Filtration Unit is ready to run at 115 volt operation. It is intended for use on a circuit that has an
outlet and a plug similar to the one illustrated in Figure A. A temporary adapter, which looks like the
adapter as illustrated in Figure B, may be used to connect this plug to a two-pole receptacle, as shown in
Figure B if a properly grounded outlet is not available. The temporary adapter should only be used until a
properly grounded outlet can be installed by a qualified electrician.
This adapter is not applicable in
Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a
permanent ground such as a properly grounded outlet box, as shown in Figure B.

If an extension cord is necessary, make sure the cord rating is suitable for the Air Filtration Unit’s listed
amperage. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.
Use the chart in Figure C as a general guide in choosing the correct size cord. If in doubt, use the next
heavier gauge. The smaller the gauge number, the heavier the cord.
