This product must be properly grounded. If the unit malfunctions or breaks down, proper
grounding provides a path of least resistance for the electric current, which reduces
the risk
of shock to anyone touching or using the equipment. Each unit is equipped with an
electrical
cord, which includes an equipment grounding conductor and a grounding plug. The plug
must be
inserted into an outlet that has been properly installed and grounded in accordance
with all
local codes and ordinances.
