1:51
all right guys welcome back to the live
1:52
stream we are wrapping up the pneumatic
1:54
cooling uh 48 volt
1:57
install um we're going to go into the
2:00
van I'm going to show you actually hold
2:01
on I got to fix that
2:05
camera
2:09
standby there we
2:13
go okay we're gonna go in the van I'm
2:15
going to show you what I did uh
2:17
yesterday um off camera so I finished up
2:20
sealing the whole entire
2:22
unit
2:23
and let's pick uh let's get some photos
2:26
going
2:28
here
2:33
all right so here you go you can see
2:35
this is the
2:37
opening and what I wanted to show you
2:39
guys is my solution to the uh intake and
2:44
the exhaust for the AC unit uh my
2:47
concern was I saw a lot of installs
2:49
where they're taking raw air from uh
2:53
this ceiling is open so if you have
2:56
havlock wool
2:58
or uh like a rock W or something um all
3:01
that dust and fibers you know it's
3:03
technically going to be sucked up into
3:05
the intake of this AC unit and so for me
3:08
just piece of mind and because I just
3:10
think it's the right thing to
3:12
do um I went ahead and I did do my
3:15
havlock insulation all the way around
3:18
here very well because this is going to
3:19
be a place where we have a massive
3:22
difference in temperature um which is
3:24
possible to create condensation in the
3:26
van so what I did is I did the havlock
3:29
around this whole entire area and then
3:31
where you see this metal foil tape I use
3:33
that to seal this chamber on the intake
3:38
from uh suing up anything in the ceiling
3:41
area and I think it's important and I
3:45
would um recommend that you guys do the
3:49
same and then on the exhaust side where
3:52
this is where blow blows out the cold
3:54
air uh let's see if I can pull up
3:55
another photo so right here um it
3:59
doesn't have to be the the neatest thing
4:00
in the world the goal is to make sure
4:03
that you are sealing this area from any
4:07
of the uh the sheet mail the metal the
4:10
insulation uh kind of think of this as I
4:14
mean it's really like your output duct
4:16
on your
4:18
home um this has the possibility to
4:21
sweat and condense because the air
4:23
coming out of here may be so cold like
4:25
you might be using this to uh you know
4:29
you have a hot van and you're ready to
4:31
cool it down a lot my recommendation is
4:34
if you're in a situation where your van
4:35
is that hot that you start the engine
4:37
let the engine AC you know drastically
4:40
cool the interior down and then when you
4:42
get it to a reasonable temperature then
4:44
turn your air conditioning unit on
4:46
there's no reason to have this thing
4:49
just work its butt off to get the whole
4:52
entire van down from like 120° for
4:56
example so what I've done is I've taken
4:58
that foil and I've just neatly just took
5:01
my time and taped everything off so
5:04
technically you could take a spray
5:06
bottle wet this whole thing down and
5:09
it's not going to go into any part of
5:12
the ceiling area it's kind to both of
5:14
those spaces are um
5:17
separate so that's what I worked on and
5:21
um this is what the final product looks
5:24
like so we have the this massive side
5:28
right here which is the intake
5:31
side and then they give you this piece
5:33
of foam um it's just got double-sided
5:36
tape on one side and then I custom cut
5:38
it around our supports and then I left
5:41
just about a 16th of an inch kind of
5:43
poking out here so that when I put the
5:46
grill on we've got a really good
5:49
seal and then this bottom section is the
5:52
section that I'm most concerned about um
5:54
any type of condensing with like a
5:56
really humid
5:58
environment
6:00
um and one reason I like going this far
6:03
is gives me peace of mind I don't have
6:05
to worry that John and Susan are going
6:07
to have any type of moisture issues if
6:09
they take a trip down to Florida it's
6:11
really humid or wherever they go um if
6:15
this does start to sweat which it
6:16
probably will um it's not the end of the
6:18
world but I know that this is completely
6:22
sealed and you know once it dries out
6:25
it's going to be fine it's not going to
6:26
affect the wood um also the nice thing
6:29
is is using
6:30
Cedar um Cedar's just pretty much going
6:34
to take care of itself to an extent but
6:37
this is now completely sealed and I can
6:40
check it off the list so what we're
6:42
going to do now is we're going to hop in
6:43
the van uh plug all the wires in and
6:47
then let's see what did I want to do I
6:49
wanted
6:51
to do one last pass through of the
6:54
instructions in case you guys are new to
6:58
this instruction manual
7:03
um so to prepare the roof we cut out a
7:06
14x 14inch Hole uh we
7:10
used uh nomatic uh let's see here let me
7:14
pull this up we use DIY
7:23
van so we use DIY Vans uh Ford Transit
7:28
high and mid roof vent adapter so this
7:30
gave us a nice flush surface to mount
7:34
the AC unit on we didn't have to use a
7:36
bunch of um you know sealant to make up
7:41
for the difference in the channel this
7:43
is a 3D U it's CNC machined so it's you
7:49
know the curves and Contours fill up all
7:51
those gaps so we don't have to just put
7:54
a ton of seiling on there um so we use
7:58
that um
8:00
we use the foam gasket that came with
8:02
nomatic Cooling and it has a
8:04
double-sided 3M Adhesive that peels off
8:07
and just sticks to the bottom of this
8:09
unit and that's our main seal then
8:11
yesterday we took black
8:13
RTV uh we put a light uh two passes
8:17
around here and we let it sit down on
8:19
there I like the RTV because it doesn't
8:21
cure um only cures for about takes 24
8:24
hours for it to cure so you got time you
8:25
got working time the cross barss we made
8:28
our own cross bars out of 1in
8:31
aluminum so we did a custom install on
8:33
that because we have a lowprofile roof
8:36
and these are two uh they're too long
8:39
number one and uh where the ends are it
8:44
doesn't seat flush to the bottom of the
8:47
van it kind of pokes out about half an
8:50
inch um we also went through here and
8:53
make sure we go through the
8:55
Electrical
8:57
uh the 10 gauge wire coming from the
9:00
nomatic cooling
9:02
unit be just heads up that's a 10 gauge
9:05
wire coming out if you're doing the
9:07
ecoflow setup like we are the wire
9:10
coming from the ecoflow is a six gauge
9:13
wire so just be prepared to have some
9:17
type of connector that can interact with
9:19
both of those gauges what I used was
9:22
this uh Anderson plug that is designed
9:26
for six gauge wire
9:30
and then what I had to do was um since
9:32
the 10 gauge was thinner I just had to
9:34
really crimp it down hard on there and
9:37
then I heat shrinked all these Terminals
9:39
and that worked out just
9:41
fine so you can see in one of these
9:45
photos uh which
9:48
one so you can see in this
9:53
photo I've got the Anderson connector
9:56
here um and then what I did was I put
9:59
electrical tape just as a backup plan so
10:02
this doesn't vibrate loose over
10:05
time going back to the
10:08
specifications um right here we have we
10:11
need a 30 amp
10:13
fuse so I put a 30 amp fuse uh in line
10:18
with the uh cable prior to plugging it
10:22
into the unit so the supply 48 volt
10:25
power cable has a 30 amp fuse in
10:28
it
10:29
and this is the one that I used right
10:31
here just a it's um pretty much car
10:35
audio style fuse so it's very easy to
10:38
get if you need
10:40
it in a pinch
10:43
um so more on
10:49
that here is the bar on this Le hand
10:52
side you will have to peel the tape away
10:56
undo two bolts to get this bar out of of
10:59
the way in order to access the
11:01
fuse but it's just tape you can ret tape
11:04
it um and then two bolt put it back into
11:06
place it's really the best solution
11:08
because it's extremely rare that this
11:11
fuse is ever going to blow I mean even
11:13
for the life of the the unit um it's
11:16
really just again the fuses protect the
11:19
wire in case of a
11:23
short uh let's see what else we
11:27
got
11:31
we did our rust preventive we sealed
11:34
everything with a Lap sealant so we Ed
11:37
3M window weld to glue down the this uh
11:42
Ford Transit vent adapter and then once
11:44
that was down I used um lap cyant to go
11:49
around the
11:52
exterior we use this leveling strip so
11:55
it's just a piece of foam in the back
11:56
that helps uh distribute the load it's
11:59
not as aggressive as if you got the X3
12:01
unit the X2 is not that heavy but this
12:05
foam
12:05
strip uh I put that in it comes with a
12:14
kit so we have a couple sensors here uh
12:17
we have an air in and an air out sensor
12:21
on the plug that we'll show you guys in
12:23
just a second which is right here the
12:27
white wire is going to be the air out
12:30
sensor so you're going to plug this wire
12:34
right here into that the big chunky one
12:37
is the control panel and that's pretty
12:40
much
12:43
it now I did zip tie I'll show you in
12:47
the video here when we get in the van
12:49
but I did zip
12:50
tie the
12:53
air in temperature sensor to the board
12:57
they just recommend that so it doesn't
12:58
flop
13:00
around or
13:02
rattle we connected
13:05
our uh DC power so that's good to
13:09
go uh we're going to get ready to put in
13:11
this powder coated trim trim ring with
13:14
the control board that's snapped into
13:16
it and then if you want to know how
13:19
everything is wired they do give you a
13:21
schematic on here and then this little
13:23
blue box that is the uh 30 amp fuse that
13:27
we installed inline fuse use it does not
13:30
come with this kit unless you order a
13:33
DIY kit um I ordered the pro kit so um
13:38
it didn't it came with it didn't come
13:40
with some things in here so for example
13:43
it didn't come with this uh
13:45
wire since we we're doing the ecoflow
13:49
but if you get it with a bundle it's
13:52
going to come with that fuse in line
13:57
already and and let's see almost
14:02
done
14:07
schematic yeah so one of these wires is
14:10
the air in that is a wire that I zip
14:14
tied to one of these chunkier wires just
14:16
so it wouldn't
14:24
vibrate um yeah these are just different
14:26
options this is the board we're going to
14:28
be using the 48
14:34
volt and that's about it so let's hop
14:37
into the van we've got our four holes
14:42
pre-drilled so that should go pretty
14:45
smooth now the screws you're going to
14:47
see they're not black they're not
14:48
painted black cuz I have some that are
14:51
drying right now so these are just going
14:52
to be some silver screws just as a
14:55
placeholder so we can knock out this
14:57
video um let's go inside and go ahead
15:01
and change mics over there we
15:04
go so we'll screw this
15:07
in and plug everything up
15:10
and that's it we will move on to next
15:14
part of the van build so if you guys can
15:17
see
15:21
here let me turn the camera
15:27
down
15:46
okay so when you have this control board
15:48
it's uh pretty much just going to snap
15:51
into place it's just got four four
15:52
plastic snaps and I'm just going to
15:54
leave this on here so it doesn't get
15:56
scratched
15:57
up we've got our divider we got our
16:00
front exhaust and then our intake and
16:02
then here is that intake temperature so
16:04
you see I just zip tied it here so that
16:07
this doesn't flap around but it still
16:09
gets our intake
16:10
temperature here is a inline fuse
16:17
um just going to take a second to see
16:19
what size this fuse is just
16:25
for we have a 7 .5 amp fuse okay so 7.5
16:32
amp fuse for the circuit
16:35
board and then we're just going to have
16:39
um all right so I'm going have to go
16:41
back to
16:43
the I forgot which one of these is the
16:46
right one to plug it into so I'm going
16:48
to go check that really
16:49
quick and then we just got this plug
16:52
that goes into the the main
16:56
plug all right let's check the manual
16:59
and see what that was supposed to
17:18
be oh it's already pulled through the
17:20
wire and harness okay it's already
17:22
plugged
17:23
in so this
17:27
uh
17:29
gotcha
17:38
okay so it's already plugged in so this
17:41
is the wire going here this one on the
17:43
very right side is this one so this will
17:46
plug in
17:48
here so that was pretty
17:52
self-explanatory but um the wires look
17:57
strong enough to actually
17:58
support this
18:00
so should be all
18:03
right
18:05
okay wires look good then let's do this
18:09
let's plug this one
18:16
in Okay so we've got all that in
18:22
there so I want to have this stuff
18:25
pushed up to the right side so it's it's
18:29
out of the
18:31
way and yeah it's pretty much just going
18:33
to live up there if there's some type of
18:34
noise
18:37
um I mean definitely you can reposition
18:40
it but it should be should be
18:43
fine the most important thing I don't
18:45
know if I can show you but the circuit
18:48
board and the divider this right here is
18:51
where that foam piece needs to go and so
18:53
when you pre-drill these holes you need
18:55
to make sure that you're not binding
18:56
against these vents or binding against
18:59
the circuit
19:16
board and if you're doing this solo just
19:19
make sure
19:22
that you have all your
19:25
screws easy to grab
19:29
now I've only pre-drilled through my
19:31
Cedar so I don't crack it but my
19:34
underlay it the quarter inch underl it
19:37
for the ceiling
19:40
um I left that so that it goes in and
19:43
bites really well now again we're just
19:46
putting silver screws in here just to
19:49
show you the install in this
19:51
video then I'm going to go back through
19:56
and put the
19:58
fancy black
20:01
painted screws in and I'm not screwing
20:04
this in the whole way I'm
20:06
just it's for the
20:09
YouTube
20:14
um
20:21
okay okay so that's pretty much it um
20:25
there's not that much adjustment so you
20:27
really need to and make sure your visual
20:30
lines
20:31
are pretty much set because you're not
20:35
going to be able to move this that much
20:37
so I've got this is my Center Line
20:39
screws with my Center vent so that looks
20:42
good my buttons and then my
20:46
rear
20:48
piece um but again I'm not binding here
20:50
at all so once I get these side ones put
20:53
in I'm not going to drill them yet I'm
20:55
just just again just doing this for the
20:57
video
20:59
but as far as the install it's not it's
21:01
not as bad as I thought I thought it was
21:03
going to take me much longer to seal
21:05
that part up the way that I like it to
21:08
be sealed um but now that it is um yeah
21:11
I'm pretty happy with
21:13
it that's it the next thing um
21:16
everything is wired so the only thing
21:18
left would be to power it on with the
21:20
ecoflow we'll do that when we do the
21:23
electrical um install which is coming up
21:27
soon
21:29
but that is the dedic sorry good
21:34
Lord nomatic cooling X2 48volt uh
21:40
rooftop
21:42
AC yep and uh let's here let's grab this
21:45
bag I'll show you what what extras that
21:48
you
21:50
get that I haven't opened this up yet
21:53
because there's no reason
21:57
to
22:02
and actually I forgot that there are
22:04
black screws
22:06
so I'll pre-drill these holes and I I'll
22:08
go ahead and use these
22:11
um if they look
22:14
good um but yeah so it does come with
22:17
some washers and some uh some other bits
22:20
and pieces
22:23
so uh and it also comes with a a remote
22:26
so that's one of the nicer parts of it
22:28
but I'm going to keep this little kit
22:31
for John and Susan and that way it's
22:33
nice and new they can open it up we can
22:36
all test
22:38
it but yeah the top is done it's all
22:42
sealed bottom is put in
22:46
um yeah I just like to wait to final do
22:49
this because until the power system
22:51
systems in I might need to actually take
22:53
this off and I don't know unplug it
22:55
reset it do something like that I have
22:58
no idea but that is
23:02
the AC
23:08
install all
23:11
right yeah so not a full tutorial
23:14
install but I think you guys get the
23:15
point if you have any questions you can
23:16
definitely put those in the comments
23:18
section below and we can do a a video on
23:20
it but um as simple as the AC is I mean
23:25
it's pretty pretty
23:26
straightforward uh I definitely want you
23:28
guys to check
23:30
out van Builder HQ if you not already
23:33
checked out the website uh we have a
23:35
bunch of blog articles um on all kinds
23:39
of stuff from floor step and trim ideas
23:42
camper van awnings the best camper van
23:45
inverter heaters for campers and these
23:48
are from all the events I go to
23:49
throughout the year so whether I'm a
23:51
vendor um going as Odyssey custom vans
23:54
or I'm going there to do a vbq
23:58
video uh I take all that
24:02
information I come back and we go
24:05
through and uh we write a nice organized
24:09
article going through different options
24:11
that will help you out um for example
24:13
this is the diesel heater I installed in
24:15
my personal
24:16
van then we have the Evo 40 which is in
24:20
the adventure van build that we have uh
24:23
that is currently for sale and then down
24:27
here we have have
24:29
uh uh the West wo smart temp which is
24:32
not only going in the adventure van but
24:34
also in John and Susan's van it's a
24:36
Bluetooth controller for the the heater
24:39
