Pre
‐
Installation
Considerations
1)
Location
and
orientation
of
the
heater.
The
heater
may
be
fitted
to
the
interior
or
exterior
of
the
vehicle.
If
it
is
installed
externally,
ensure
that
the
heater
is
fitted
in
a
position
where
it
is
protected
from
water
and
dust
ingress.
2)
Length
of
hot
air
outlet
ducting
–
the
shorter,
the
better.
Ensure
that
the
hot
air
outlet
is
not
directed
towards
or
in
contact
with
the
human
body,
as
the
hot
air
temperature
can
range
from
80
‐
120
o
C.
3)
Return
vent
‐
in
some
cases
where
there
is
enough
air
circulation
in
and
around
the
heater,
ducting
may
not
be
required
to
the
return
air
vent.
Where
it
is
required,
keep
ducting
to
a
minimum.
4)
Location
of
the
controller,
electrical
wiring,
fuse
and
battery
connections.
5)
Location
of
the
fuel
pump
and
fuel
filter.
6)
Location
of
the
exhaust
system.
Ensure
that
the
exhaust
is
not
facing
direction
of
travel.
7)
Location
of
the
combustion
air
systems.
8)
Fuel
pick
‐
up
options
–
12L
Webasto
fuel
tank
or
standpipe.
9)
Electrical
‐
ensure
to
use
the
supplied
fuses
in
the
kit
and
battery
positive
and
negative
connected
directly
to
the
house
battery.
Tips
Loosely
attach
the
heater
with
the
mounting
bracket
and
place
it
in
your
desired
location
to
predetermine
the
heater
orientation,
ducting
layout,
airflow,
wiring,
controller
and
general
clearance
for
easy
accessibility
and
for
future
service
and
repair.
Serial
Number
Labelling
Ensure
that
the
serial
number
labels
are
attached
on
the
top
or
the
side
of
the
heater
in
case
the
heater
is
mounted
against
a
wall
and
the
original
label
may
be
inaccessible.
Additional
labels
are
supplied
in
the
kit
and
one
should
go
on
the
installation
manual
envelope
to
hand
over
to
the
customer
at
the
time
of
commissioning.
The
Serial
Number
label
on
the
AT2000STC
will
still
state
AT2000ST.
This
is
to
avoid
the
necessity
of
applying
for
a
new
EC
type
approval.
The
heater
will
still
be
an
AT2000STC
based
on
the
manufacture
date
and
serial
number.
Note:
In
case
of
warranty
situations,
the
serial
number
will
be
requested
by
Webasto
or
an
authorised
dealer
to
validate.
