7.0 Electrical Connections
Electrical connections should be made by a qualified electrician in compliance with all relevant
codes. Failure to comply may cause serious injury.
The ISF-1000 Air Filtration System is prewired for single phase, 120V power. It is provided with a plug designed for use on
a circuit with a grounded outlet that looks like the one pictured in Figure 7-1.
It is recommended that the ISF-1000 be connected to a 15 amp circuit with a circuit breaker or fuse. If fuses are used, they
should be time-
delay fuse marked “D”.
Local codes take precedence over recommendations.
7.1 Grounding Instructions
1. All Grounded, Cord-connected Tools:
This machine must be grounded. 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. Failure to comply may cause
serious or fatal injury.
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.
Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating
less than 150
volts:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 7-1.
