ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
PROCEDURE
FURNACE RELIABILITY HAZARD
hnproper 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 fln'nace installation and servicing to
protect the furnace electronic controh Precautions will pre-
vent electrostatic discharges fl'om 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 DIS-
CHARGING YOUR BODY'S ELECTROSTATIC CHARGE
TO GROUND.
2. Firmly touch the clean, unpainted, metal surface of the limmce
chassis which is close to the controh Tools held in a person's
band 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 to
recharge your body with static electricity (lbr example; DO
NOT move or shuffle your IL'et, do not touch ungrounded
objects, etc.).
4. If you touch ungrounded objects (and recharge your body with
static electricity), firndy touch a clean, unpainted metal
surlilce of the furnace again betk_re touching control or wires.
5. Use this procedure li)r installed and uninstalled (ungrounded)
lul'naces.
6. Belbm ren-ioving a new control li"om its container, discharge
your body's electrostatic charge to ground to protect the
control from damage. If the control is to be installed in a
lurnace, lbllow items 1 through 4 belore bringing the control
or yourself in contact with the limmce. Put all used and new
controls into containers belbm touching ungrounded objects.
7. An ESD service kit (available from commercial sources) may
also be used to prevent ESD damage.
LOCATION
GENERAL
This nmltipoise furnace is shipped in packaged configuration.
Some assembly and modifications are required when used in any
of the %ur applications shown in Fig. 4.
This furnace nmst:
be installed so the electrical components are protected from
water.
not be installed directly on any combustible material other than
wood flooring (reli:r to SAFETY CONSIDERATIONS).
be located as close to the chinmey or vent and attached to an air
distribution system. Reler to Air Ducts section.
be provided ample space lor servicing and cleaning. Always
comply with minimum fire protection clearances shown on the
furnace clearance to combustible label.
