Grounding
This equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
1.
Verify that the PD2K base unit is properly
grounded. See the PD2K installation manual for
complete grounding instructions.
2.
Ground the expansion kit pump(s) as follows:
