ELECTROSTATIC DISCHARGE (ESD) PRECAUTION PROCEDURE

CAUTION: Electrostatic discharge can affect electronic components. Follow the Electronic Discharge Precautions Procedure listed below during furnace 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 furnace chassis which is close to the control. Tools held in hand during grounding will be 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, firmly touch a clean, unpainted metal surface 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 charge to ground. If the control is to be installed in a furnace, follow items 1 through 4 before bringing the control or yourself in 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.

APPLICATIONS

PROCEDURE 1—GENERAL

Some assembly and modifications are required for furnaces installed in any of the 4 applications shown in Fig. 1. All drain and pressure tubes are connected as shown in Fig. 5. See appropriate application instructions for these procedures.
