NOTE:
Do
not
use
any
louvered
hoods
with
installation
of
LIFEBREATH
HRV,
as
this
will
restrict
the
required
air
flow.
The
TECHGRILLE
is
a
round,
fully
adjust¬
able
grille,
which
provides
superior,
quiet
air
distribu¬
tion.
See
Fig.
3.
The
fresh
air
supply
from
the
HRV
to
the
house
can
follow
several
installation
strategies.
See
Figures
#4
and
#5
for
two
installation
schematics.
The
installa¬
tion
schematic
shown
in
Figure
#4
has
proven
to
be
an
excellent
method
for
both
retrofit
and
new
home
situa¬
tions
where
a
forced
air
furnace
is
available.
The
installation
schematic
shown
in
Figure
#5
is
often
installed
in
new
or
exisiting
homes
that
do
not
have
a
forced
air
ducting
system
to
distribute
the
fresh
air
throughout
the
house.
For
Figure
#5,
fresh
air
should
be
supplied
to
all
rooms,
but
it
is
not
required
in
those
with
exhaust
points
in
them.
Supply
airgrilles
may
be
floor
or
highwallmounted,
but
should
not
be
located
in
areas
where
the
fresh
air
will
cause
an
uncomfortable
draft
on
the
occupants.
to
avoid
drafts
.
Avoid
installing
supply
air
grilles
in
bathrooms,
or
any
other
small
room
(with
significant
air
quality
problems)
if
it
has
an
exhaust
duct.
INSTALLATION
FIGURE
#6
In
this
method,
the
supply
air
is
ducted
directly
into
the
cold
air
return
of
the
central
forced
air
furnace.
NOTE:
The
installation
schematics
show
a
balancing
damper
on
the
supply
duct
leaving
the
unit.
This
is
installed
to
balance
the
supply
of
air
from
the
unit.
Should
you
wish
to
hard
duct
the
supply
air
directly
into
the
cold
air
return
of
the
furnace,
remember
to
check
the
air
flow
balance
of
the
HRV
with
the
furnace
fan
both
"ON"
and
"OFF”
to
determine
that
it
does
not
imbalance
the
HRV
more
than
10%.
Also,
it
is
advisable
to
include
a
short
length
of
fabric
flex
duct
or
other
non-metallic
connector
in
this
hard
ducted
line
in
order
to
keep
the
HRV
separately
grounded
(electri¬
cally)
from
the
furnace.
This
will
avoid
a
possible
shock
hazard
to
Service
People
if
a
short

ground
develops
in
one
of
the
devices.
STALE
AIR
RETURN
SYSTEM
The
stale
air
return
system
is
used
to
draw
air
from
the
points
in
the
house
where
the
worst
air
quality
problems
occur.
It
is
recommended
that
return
air
ducts
are
brought
backfrom
the
bathroom,
kitchen,
and
laundry
room.
Additional
return
air
ducts
from
strategic
locations
(i.e.
greenhouse,
atrium,
swimming
pool,
sauna,
etc.)
may
be
installed.
Notethatthe
installation
schematics
show
balancing
dampers
and/or
adjust¬
able
grilles
on
all
return
air
lines
coming
back
to
the
unit.
These
are
installed
to
help
balance
the
"draw"
from
the
different
areas
of
the
house.
The
damper
located
just
priorto
the
Heat
Recov¬
ery
Ventilator
is
provided
to
balance
the
stale
air
exhausted
out
of
the
house
with
fresh
air
supply
enter¬
ing
the
house.
We
recommend
the
use
of
high
duct
mounted
wall
returns
with
grilles.
The
exhaust
air
line
from
the
kitchen
should
never
be
connected
to
a
range
hood.
Instead,
an
exhaust
air
grille
should
be
mounted
high
on
the
wall
at
least
4
ft.
(1.2
m)
horizontally
away
from
the
stove.
A
flip
up
8"
x
10"
rectangular
kitchen
grille
with
removable
grease
filter
is
available
from
NUTECH
if
desired.
The
gyproc
and
studs
of
the
wall
can
be
used
as
a
"duct"
for
high
wall
returns.
When
using
wall
cavities
this
way,
they
should
be
lined
with
either
galvanized
sheet
metal
or
polyethylene
(check
Local
Codes).
The
wall
plate
and
the
floor
ply
must
be
cut
out
to
accept
either
ducting
or
the
proper
sized
sheet
metal
boot.
INSTALLATION
FIGURE
#7
In
this
method,
the
exhaust
air
is
not
ducted
back
to
the
HRV
with
"dedicated
lines":
from
bathrooms,
kitchens,
etc.
Instead,
the
exhaust
air
is
drawn
out
of
the
cold
air
return
of
the
central
forced
airfurnace.
This
method
has
become
popular
and
provides
good
venti¬
lation
when
installed
in
accordance
with
the
noted
instructions.
