Electrostatic Discharge (ESD) Precautions
NOTE:
Discharge your body’s static electricity before touching
unit. An electrostatic discharge can adversely affect electrical
components.
Use the following precautions during furnace installation and
servicing to protect the integrated control module from damage.
By putting the furnace, the control, and the person at the same
electrostatic potential, these steps will help avoid exposing
the integrated control module to electrostatic discharge. This
procedure is applicable to both installed and non-installed
(ungrounded) furnaces.
1. Disconnect all power to the furnace. Do not touch the
integrated control module or any wire connected to the
control prior to discharging your body’s electrostatic charge
to ground.
2. Firmly touch a clean, unpainted, metal surface of the furnaces
near the control. Any tools held in a person’s hand during
grounding will be discharged.
3. Service integrated control module or connecting wiring
following the discharge process in step 2. Use caution not to
recharge your body with static electricity; (i.e., do not move or
shuffle your feet, do not touch ungrounded objects, etc.). If
you come in contact with an ungrounded object, repeat step
2 before touching control or wires.
4. Discharge your body to ground before removing a new control
from its container. Follow steps 1 through 3 if installing the
control on a furnace. Return any old or new controls to their
containers before touching any ungrounded object.
