4. ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS PROCEDURE
3.1 Safety
CAUTION
Improper installation or service of furnace may cause prema-
ture 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 electro-
static 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.
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.
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.
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.).
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,
Use this procedure for installed and un installed (ungrounded)
furnaces.
