Use
the
dual
7
‐
segment
LED
display
adjacent
to
the
dip
switches
to
obtain
the
approximate
airflow
quantity
.
The
airflow
quantity
is
displayed
as
a
number
on
the
display,
rounded
to
the
nearest
100
CFM
.
The
display
alternates
airflow
delivery
indication
and
the
operating
mode
indication.
If
the
airflow
being
delivered
is
1375,
CFM,
the
LED
display
will
indicate
a
“14.”
(for
1400
CFM)

Determine
the
tonnage
of
the
cooling
system
installed
with
the
furnace.
If
the
cooling
capacity
is
the
BTU/hr,
divide
it
by
12,000
to
convert
the
capacity
to
tons.
So,
if
your
cooling
capacity
requirement
is
42,000
BTU/hr
then
42,000
÷ 12,000
=
3.5
tons.
Determine
the
proper
air
flow
for
the
cooling
system.
Most
cooling
systems
are
designed
to
work
with
air
flows
between
350
and
450
CFM
per
ton.
3.5
tons
X
400
CFM
=
1400
CFM.
