System Grounding - Grizzly EXTREME Series Owner's Manual

Ensure Required CFM at Machine
Since each machine produces a different amount
of dust, the requirements for the minimum amount
of CFM to move that dust is unique to the machine.
Knowing this required CFM is important to gaug-
ing what size duct to use.
For best results when using a Y-inlet, we recom-
mend installing blast gates to control airflow for
each line near the Y-inlet.
Refer to Figure 17 for a close estimation of the
airflow each dust-producing machine requires.
Machines that generate the most dust should be
placed as close as possible to the dust collector.

System Grounding

To guard against static electrical buildup, we
strongly recommend replacing any plastic dust
ports on dust-producing machines
equivalents.
If you absolutely must use any plastic duct or
components, they must be completely grounded
and bonded to the metal frame of a grounded
machine by wrapping the flex hose with an exter-
nal ground wire connected to both machines as
shown in Figure 18. Ensure that each machine is
continuously grounded to the grounding terminal
in your electric service panel.
