CAUTION
ELECTROSTATIC DISCHARGE
(ESD)
Precautions and Procedures
Electrostatic discharge can affect electronic components. Take precautions
during unit installation and service to protect the unit’s electronic controls.
Precautions will help to avoid control exposure to electrostatic discharge by
putting the unit, the control and the technician at the same electrostatic potential.
Neutralize electrostatic charge by touching hand and all tools on an unpainted unit
surface before performing any service procedure
