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.

3.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.

4.Firmly touch a 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.

5.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 un- grounded objects, etc.).

6.If you touch ungrounded objects (recharge your body with static electricity), firmly touch furnace again before touch- ing control or wires.

7.Use this procedure for installed and uninstalled (ungroun- ded) furnaces.

8.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 5 before bringing the control or yourself into contact with the fur- nace. Put all used AND new controls into containers be- fore touching ungrounded objects.

9.An ESD service kit (available from commercial sources) may also be used to prevent ESD damage.
