ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
NOTE: Discharge static electrictiy accumulated in the body before touching the unit. An electrostatic discharge can adversely affect electrical components.
Use the following precautions during furnace installation and ser- vicing to protect the integrated control module from damage. By putting the furnace, the control, and the person at the same electro- static potential, these steps will help avoid exposing the integrated control module to electrostatic discharge. This procedure is appli- cable to both installed and
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 furnace 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.
