ceiling template right there on top
grill
so
pre-fab with the j box already on top and a test wire they give you
plug it in and make sure it works
so this should turn on here
gives you the timer high/low switch and a faceplate. the only thing you need is
see the template it's designed in a way where it's supposed to fit in between 16-inch on-center
trusses so even when you don't have a lot of room it is designed to fit into these smaller bays as
well perfect so based on the truss layout in this house hallway is here that we're in now
that weighs a little bit towards the back of the house a little close to the edge
i can get it a little more centered if i go that way right here would be perfect but my unit's here
i'm gonna see based on where's available in the attic uh the unit is like
like right here. your ac unit
if I went up here it'd be probably somewhere in that range which is in view
of the living room area but it's still centralized or if I have the front door open in the back
it's going to pull evenly from all sides whereas if the other if I went the other way with it
I have right about here you know anywhere in this area um which if I had everything open
I would pull more heavy from this side and I'd be a little bit lighter from places like the
kitchen and the living room which also could I mean there are quiet cools they're designed
to be as quiet as possible but sleeping in the bedrooms here we do also then have a fan closer
uh with somebody with a sensitive year might be able to might wake up today true
on both sides so that's great I just make my corners
one thing I like to do is you know as I get my template put in here and I know where I'm going to
be I then clean it out you know physically clean all the insulation off the top of it so once I cut
it's less of a mess downstairs helps you out cleaning and looks a lot more professional
and that way you just don't have a bunch of stuff falling in your face while you're doing your job
a lot of times what I do after I get my placement in my hole cut um is I figure out where I want to
want things like electrical the fan itself I want to get all that stuff up there figure out where
I'm going to get power from and where I want to put the switch because once I put all that stuff
up in there, especially in an attic like this it's pretty tight I'm gonna be losing my I'm gonna be
making it so I don't have as much space as I could so uh that's where I do all of this stuff
in a scenario like this where the wood is our framing is right here and right here
uh you can remove these if you look in here it's just a little tab that they've put in there so
you just loosen them up a lot of times you can even do it by hand but you can grab a screwdriver
I'll keep these two because there's nothing on that side so it'll
still help sandwich the sheetrock the uh helpful thing that's quite cool does a lot of times is uh
if you have a really large whole house fan it's hard to get stuff up into the attic especially
at the attic access like even here access is pretty small but everything that they design
is 14 and a quarter inches is the template so everything is designed to fit through that hole
including if you take the duct off the fan itself fits up exactly like that as well
all right
all three pieces are unlocked
okay so what colin's doing right here is he is separating the blower housing from the duct
is about six feet long so he's gonna put the blower housing about four feet away from
the damper box that you're going to see from the ceiling
here what I'm doing once I've got all the pieces in place is I can set my fan I know
where I'm going with it based on my distance of duck probably gonna be somewhere right about here
so it sits flush on our sheet rod hole that we made
and even though it's got the tabs on it if I'm up against a piece of wood I'm still going to
put a screw in it just in case at some point anybody else ever comes up here with tools and
put something on it the last thing I wanted to do is go falling down through the sheetrock
get my dust on so I know exactly where my fan can go
uh
so the duct is what helps make it quiet so having this bend on it uh doesn't
increase resistance as much as it actually helps for noise inside the house
screw in
they do make a nice little uh feature we can just get the screw in first a little bit of
the way into the wall and then you can hit it with the hook there so you can take the weight off to
be in for my wiring um so what I usually do is instead of getting the fan set in place
everything's strapped up and put together because then the j box would be like right
there and everything would be quite a bit harder so you don't have to do it at a certain point you
can do it anytime so get yourself uh into at least a semi-comfortable position and your wiring then
two different 14 2 wires come out of the fan and down to your switch which is a double gang so they
both are 14 2 so you gotta remember which one is your power and which one's your speeds so set that
cell phone set that up for yourself beforehand so this one I hung out of the access with my
I'll power one at a time don't get mixed up in the wall
higher before this is our power wire so how the switches are going to sit in the box is
going to be our power on the left and our high and low-speed selection on the right then once I feed
the second one in I feed it over here when I'm in the box there's no confusion to which one is which
got it
now my speeds and my
power is in the box get the box into the wall make sure you obviously give yourself enough room
in the attic to staple everything
so here's the power switch these are my power wires they come in
on the left that's where I put them into the box and then my
high low-speed switch on this side see from the diagram here my black and white
are tied into my standard 120 volts coming in then the red is the jumper power to my speed switch
which then the selector switch gives you whichever one you're clicked onto and if you follow the
diagram obviously high everything legible wouldn't make sense to have it here jumper switch to that
side high and low to the side another thing that goes against uh your common intuition a little
bit when you're wiring it is this white wire here since it's your speed switch is not tied into your
commons so make sure that when you're looking at it black and the white to come off of your power
timer are the only hots and commons that get tied together but you do tie in all three ground wires
but your two whites are not both white so what I'm going to do is I'm going to tape this one
red so that anybody comes in here and they can tell that this is a hot wire
good on power everywhere before I actually put it all in the wall
I'm going to go hit the power to the thing and I'm going to test it right now
and uh yeah be nice to everybody else and label where it was your brain put it on your breaker now
it's low that's high
so the pro series gives you this grill
and this little key thing that you can stick in here when it's on on the ceiling you can
pull that out and if you ever wanted to you could take this thing out to take it out and clean it
so as you remember from earlier these two sides aren't wood
they're just a metal flange so make sure you're not cranking them down
