ALUM-NOD
（
No
need
to
drill
holes
in

flue
）
a.
Installation of air duct and coil base directly facing window
:
Disassemble
a
glass
and
assemble
plywood
with
exhaust
holes
,
or
drill
holes
on
the
glass
directly
.
b.
When coil base is not close to window:
Select the nearest coil base, install the air duct on the window
accessible to outdoor to penetrate the window
;
or
select
the
nearest
coil
base
,
drill
hole
on
the
wall
accessible
to
outdoor
and
install
air
duct
to
penetrate the wall.
c
.
Drill the wall opening:
Measure the position that air duct faces wall and mark the drilling scope on the wall
surface (i.e. circle a little larger than outer diameter of air duct), then use long drill to drill the wall. Pay attention to
the wall structure and material while drilling and do not damage the wall besides wall opening.
Connect the
ALUM-NOD
First connect the ALUM-NOD without air duct fixed strip with air duct interface, sealed by adhesive tape of air
duct and straighten the ALUM-NOD to outdoor directly. When the wall hole is larger than ALUM-NOD, the air duct
can be pulled to outdoor directly
;
when
the
wall
hole
is
smaller
than
air
duct
,
it
can
be
selected
according
to
the
hole size since the small end of air duct interface has four specifications: 140, 150, 160 and 170. The surplus
part that is smaller than wall hole can be cut by scissor.
Then insert the other end of ALUM-NOD with air duct fixed strip between internal and external ring of check valve
outlet and seal it by adhesive tape of air duct. Last, put the 4 fasteners into the slots and rotate clockwise
,
the
ALUM-NOD is fixed on the check valve.
