3. Assemble and install downflow subbase per instruc­
tions packaged with subbase.
4. When completed, downflow subbase, plenum, and fur­
nace (or coil casing when used) should be installed as
shown in Fig. 4.
VII. ELECTRICAL CONNECTIONS
A. 115-Volt Wiring
iM PORT ANT: Before proceeding with the electrical connec­
tions, make certain that voltage, frequency, and phase cor­
respond to that specified on the unit rating plate and Table
3. Also, check to be sure that the service provided by the
utility is sufficient to handle the load imposed by this equip­
ment. Refer to Table 3 for the equipment electrical
specifications.

»Permissible limits of the voltage range at which the unit will operate sat­
isfactorily.
fTime-delay fuse is recommended.
^Length shown is as measured one way along wire path between unit
and service panel for maximum 2% voltage drop.
A CAUTION
Do not connect aluminum wire between the disconnect
switch and the furnace.
See Fig. 6 for a wiring diagram showing the proper field
115- and 24-volt wiring. Be sure field wiring complies with
the National Electric Code and any local codes or ordnances
that may apply. Voltage to the furnace must be within the
limits shown in Table 3. Contact your local power company
for correction of improper voltage.
NOTE; Operation of unit on improper line voltage consti­
tutes abuse and could affect unit reliability. Do not install
the furnace in a system where voltage may fluctuate above
or below permissible limits.
Use a separate fused branch electrical circuit containing the
properly sized time-delay fuse or HACR-type circuit breaker
for this furnace. See Table 3 for fuse and wire specifications.
A disconnecting means must be located within sight of, and
readily accessible to, the furnace. The blower door switch
may be acceptable in some areas as a disconnecting means.
Line voltage must enter the auxiliary J-box on the right-
hand side of the furnace.
A WARNING
The cabinet must have an uninterrupted or unbroken
ground according to National Electrical Code. ANSI/
NFPA 70-1987, or local codes to minimize personal
injury if an electrical fault should occur. This may con­
sist of electrical wire or conduit approved for electrical
ground when installed in accordance with existing elec­
trical codes. Do not use gas piping as an electrical
ground. A failure to adhere to this warning can result in
an electrical shock, fire, or death.
