CONDENSATE
DRAINS
Unit
is
provided
with
primary
and
secondary
3/4”
(19mm)
NPT
drain
connections.
Refer
to
Figure
3,
Figure
4,
Figure
5,
Figure
6,
and
Figure
7
to
identify
the
primary
and
secondary
locations.
To
prevent
property
damage
and
achieve
optimum
drainage
performance,
BOTH
primary
and
secondary
drain
lines
should
be
installed
and
include
properly
sized
condensate
traps
(refer
to
Figure
21).
Factory
approved
condensate
traps
are
available
(accessory
part
number
EBACO1CTK).
To
connect
drainlines,
the
drain
connection
knock-outs
must
be
removed.
Use
a
knife
to
start
the
opening
near
the
tab
and
using
pliers,
pull
the tab
to
remove
the
knock-out.
Clean
the
edge
of
the
opening
if
necessary.
After drain
fittings
are
installed,
caulk
the
seam
between
the
fitting
and
the
cover
to
retain
the
low
leak
rating
of
the
unit.
It
is
recommended
the
PVC
fittings
be
used
on
the
plastic
condensate
pan.
Do
not
over-tighten.
Finger-tighten
plus
1-1/2
turns.
Use
pipe
dope,
to
ensure
proper
seal.
Install
traps
in
the
condensate
lines
as
close
to
the
coil
as
possible
(refer
to
Figure
23),
but
avoid
blocking
filter
access
panel.
Install
drain
lines
below
the
bottom
of
the
drain
pan
and
pitch
the
drain
lines
down
from
the
coil
at
least
1/4
inch
per
foot
of
run
(6mm
per
0.3m).
Horizontal
runs
over
15
feet
(5m)
long
must
also
have
an
anti-siphon
air
vents
(stand
pipes),
installed
ahead
of
the
horizontal
runs.
Extremely
long
horizontal
runs
may
require
oversized
drain
lines
to
eliminate
air
trapping.
Route
primary
drain
line
to
the
outside
or
to
a
floor
drain.
Check
local
codes
before
connecting
to
a
waste
(Sewer)
line.
Route
the
secondary
drain
line
to
a
place
in
compliance
with
local
installation
codes
where
it
will
be
noticed
when
unit
is
operational.
Condensate
flowing
from
secondary
(overflow)
drain
indicates
a
plugged
primary
drain
-
unit
requires
service
or
water
damage
will
occur.
Prime
all
traps,
test
for
leaks,
and
insulate
drain
lines
where
sweating
could
cause
water
damage.
Consult
local
codes
for
additional
requirements
or
precautions.
If
a
gravity
drain
cannot
be
used,
install
a
condensate
pump.
Install
the
pump
as
close
to
the
indoor
section
as
possible.
A
CAUTION
PRODUCT
or
PROPERTY
DAMAGE
HAZARD
Failure
to
follow
this
caution
may
result
in
product
or
property
damage.
Use
only
full
size
P-traps
in
the
condensate
line
(refer
to
Figure
21).
Shallow,
running
traps
are
in-
adequate
and
DO
NOT
allow
proper
condensate
drainage
(refer
to
Figure
22).
