RECAUTIONS

NOTE:

  Discharge 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.
