ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
CAUTION: UNIT DAMAGE HAZARD
Failure to follow this caution may result in damage to unit components.
Electrostatic discharge can affect electronic components. Take precautions during furnace installation and servicing to protect the
furnace electronic control. Precautions will prevent electrostatic discharges from personnel and hand tools which are held during the
procedure. These precautions will help to avoid exposing the control to electrostatic discharge by putting the furnace, the control, and
the person at the same electrostatic potential.
1. Disconnect all power to the furnace. Multiple disconnects may be required. DO NOT TOUCH THE CONTROL 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 chassis which is close to the control. Tools held in a person’s hand during
grounding will be satisfactorily discharged.
3. After touching the chassis, you may proceed to service the control or connecting wires as long as you do nothing that recharges your body
with static electricity (for example; DO NOT move or shuffle your feet, DO NOT touch ungrounded objects, etc.).
4. If you touch ungrounded objects (recharge your body with static electricity), firmly touch a clean, unpainted metal surface of the furnace
again before touching control or wires.
5. Use this procedure for installed and uninstalled (ungrounded) furnaces.
6. Before removing a new control from its container, discharge your body’s electrostatic charge to ground to protect the control from damage.
If the control is to be installed in a furnace, follow items 1 through 5 before bringing the control or yourself into contact with the furnace.
Put all used AND new controls into containers before touching ungrounded objects.
7. An ESD service kit (available from commercial sources) may also be used to prevent ESD damage.
