ELECTROSTATIC DBSCNARGE {ESD) PRECAUTIONS
e
[NIT 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 servicing to
protect the furnace electronic control. Precautions will pre-
vent electrostatic discharges t]'om personnel and hand tools
which are held during the procedure. These precautions will
help to avoid exposing the control to electlostatic discharge
by putting the t:umacQ the control, and the person at the same
electrostatic potential.
1. Disconnect all power to the furnace. Multiple disconnects may
be required. DO NOT TOU(H THE CONTROL OR ANY
WIRE CONNE(TED TO THE ( ONTROL PRIOR TO DIS-
CHARGING YOUR BODY'S ELECTROSTATI( CHARGE
TO GROUND,
2 Firefly 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 tong as you do nothing that
recharges your body with static electricity (fbr example; DO
NOT move or shuffle your feet, DO NOT touch ungrounded
objects, etc)
4 If you touch ungrounded objects (recharge your body with
static electricity), firmly touch f_/rnace again befbre touching
control or wires
5 Use this procedure for installed and uninstalled (ungrounded)
f_/rnaces
