ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

CAUTION!

Use caution when installing and servicing the furnace to avoid and control

electrostatic discharge; ESD can impact electronic components. These

precautions must be followed to prevent electrostatic discharge from hand

tools and personnel. Following the precautions will protect the control from

ESD by discharging static electricity buildup to ground.
