5 Electrostatic Discharge (ESD) Precautions Procedure

NOTICE: 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 board to
electrostatic discharge by putting the furnace, the control
board, and the person at the same electrostatic potential.
1. Disconnect all power to the furnace. Multiple disconnects maybe required.
DO NOT TOUCH THE CONTROL OR ANY WIRE CONNECTED TO THE
CONTROL PRIOR TO DISCHARGING YOUR BODY'S ELECTROSTATIC
CHARGE TO GROUND.
2. To discharge your body's electrostatic charge to ground, fi rmly touch the
clean, unpainted, metal surface of the furnace chassis which is close to
the control board.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 board or
connecting wires as long as you do nothing to recharge your body with static
electricity (for example; DO NOT move or shuffl e your feet, do not touch
ungrounded objects, etc.).
4. If you touch ungrounded objects (and recharge your body with static
electricity), fi rmly touch a clean, unpainted metal surface of the furnace
again before touching control board or wires.
Use this procedure for installed and uninstalled (ungrounded) furnaces. In the case
of control board replacement, before removing the replacement control board from
its packaging, 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 steps 1
through 4 before bringing the control board or yourself in contact with the furnace.
Put all used and new control boards into containers before touching ungrounded
objects.
An ESD service kit (fi eld supplied) may also be used to prevent ESD damage.
