ELECTROSTATIC DISCHARGE
(ESD) PRECAUTIONS

PROCEDURE

CAUTION

FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in unit

Electrostatic discharge
components. Take precautions
installation and servicing to protect the furnace
electronic control.
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 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
to recharge your body with static electricity (for example;

during furnace
Precautions will prevent
Specifications subject to change without notice.
DO NOT move or shuffle your feet, do not touch
ungrounded 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
(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 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.
