ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS PROCEDURE
CAUTION
!
FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in unit component
damage.
Electrostatic discharge can affect electronic components.
Take precautions during
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.

Specifications are subject to change without notice.
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
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 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 (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 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 ungroun-
ded objects.
7. An ESD service kit (available from commercial sources)
may also be used to prevent ESD damage.
