when
installed
in
accordance

CONNECTIONS
1.
Provide
a
power
supply
separate
from
all
other
circuits.
Install
overcurrent
protection
and
disconnect
switch
per
local/national
electrical
codes.
The
switch
should
be
close
to
the
unit
for
conve-
nience
in
servicing.
With
the
disconnect
or
fused
switch
in
the
OFF
position,
check
all
wiring
against
the
unit
wiring
label.
Refer
to
the
wiring
diagram
in
this
instruction.
2.
Remove
the
screws
retaining
the
wiring
box
cover.
Route
the
power
wiring
through
the
opening
in
the
unit
into
the
junction
box
with
a
conduit
connector
or
other
proper
connection.
In
the
junction
box
there
will
be
three
wires,
a
Black
Wire,
a
White
Wire
and
a
Green
Wire.
Connect
the
power
supply
as
shown
on
the
unit-wir-
ing
label on
the
inside
of
the
blower
compartment
door
or
the
wir-
ing
schematic
in
this
section.
The
black
furnace
lead
must
be
connected
to
the
L1
(hot)
wire
from
the
power
supply.
The
white
furnace
lead
must
be
connected
to
neutral.
Connect
the
green
fur-
nace
lead
(equipment
ground)
to
the
power
supply
ground.
3.
The
furnace's
control
system
requires
correct
polarity
of
the
power
supply
and
a
proper
ground
connection.

pigtails.
NOTE:
Five-conductor
thermostat
cable
is
recommended
for
ail

at
a
later
time.
IMPORTANT
Set
the
heat
anticipator
in
the
room
thermostat
to
0.40
amps.
Set-
ting
it
lower
will
cause
short
cycles.
Setting
it
higher
will
cause
room

to
exceed
the
set
points.
