ELECTROSTATIC DISCHARGE (ESD)

PRECAUTIONS PROCEDURE

!CAUTION

FURNACE RELIABILITY HAZARD

Improper installation or service of furnace may cause premature furnace component failure.

Electrostatic discharge can affect electronic components. Follow the Electrostatic Discharge Precautions Procedure listed below 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 the clean, unpainted, metal surface of the fur- nace chassis which is close to the control. Tools held in a person’s hand during grounding will be satisfactorily dis- charged.

3.After touching the chassis, you may proceed to service the control or connecting wires as long as you do nothing to recharge your body with static electricity (for example; DO NOT move or shuffle your feet, do not touch un- grounded objects, etc.).

4.If you touch ungrounded objects (and 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 (ungroun- ded) furnaces.

6.Before removing a new control from its container, dis- charge your body’s electrostatic charge to ground to pro- tect the control from damage. If the control is to be in- stalled in a furnace, follow items 1 through 4 before bringing the control or yourself in contact with the fur- nace. 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.
