ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

CAUTION: UNIT DAMAGE HAZARD
Failure to follow this caution may result in damage to unit
components.
Electrostatic discharge can affect electronic components.
Take precautions during furnace installation and servic-
ing 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 a 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 that
recharges your body with static electricity (for example; DO
NOT move or shuffle your feet, DO NOT touch un-
grounded objects, etc.).
