okay now we're up here on the top of the office building where we were installing
the air handler we've got our condenser set we're almost finished running our electrical line over
here very important to always check your voltage on the machine 9s and 12s or 115 volt so we'll
run our line I'll double check it at our box and then we'll do our install but what I want to show
you real important is because we're above a roof or if you're doing it on a bracket mount above
anything that you won't condensate to drain away from as a heat pump installs I mean it actually
makes condensate during the winter operations so that's something you want to keep in mind on
the bottom of the condenser there are two plugs two holes we have one on each what I'm gonna do
is pick the right hole for my application and then I'm going in stall a plug in one and then
I'm going to install a drain tube and the other so for my particular application I'm going to
install my drain tube right in the very back and it just snaps right in rubber seal all around it
and then my plug will actually go into my other hole and then it just pushes right up tight seal
also for the sake of time today we're not going to put it in a pan just to get it done but we'll also
put a auxilary pan up under this machine and that way for safety purposes will catch any condensate
that's not caught by that drink so anytime you're both a sealant and bicode most time they recommend
a secondary pan if it's outside on a bracket it really doesn't matter but above a ceiling put
a pan in run auxilary drain out so anyway we're going to start our install we'll put it up on two
blocks make up connections and finish our wiring okay for the sake of light I'm going to show you
how to make the wire connections very quickly basically what we do is we run our high voltage
in one side around our control voltage general to other if we were outside in an outdoor environment
of course we want to put this in conduit not a room X but our high voltage basically we're going
to take our neutral wire and take it to in on our incoming power side from our disconnect and we'll
put it up under them and secure that connection we have our ground on our grounding lug at the
bottom our hot wire which is our black we're going to take it to L from our disconnect okay
okay now we have our outdoor sensor while if some reason you can't find this wire inside your
machine just pull your top off and just take a look there's more likely it bounced around
and it's not sitting right here so basically all you do is you take it and you just snap it right
in and then just take it took it took it out of your way for time being now we've got all your
lead from your indoor unit to your outdoor unit and basically is straighten up all your wires so
they'll go in there nice and neatly and you want to go back to your manual we would your little
piece of paper where you wrote down which one you put on which one make sure they correspond
that's very important so on number one we use blue so we'll take blue and put it up under one
then we'll take orange and put it up on your number two
number three we're going to use yellow
and like I say all of this matches what I did on the indoor unit your color codes
might change it might be different just make sure the same exact wire
no matter what the color inside is the same outside and then l1 we have black
in one we have red and brown we have ground
okay now there's all wires now we got that done we just want to make sure we put them up under
the designated connection areas so that wire stays good and tight and secure and that's all it is to
it you'll notice you have two L's and two ends one set of L's on the far right are going to be
the ones for the high voltage from disconnect in and the other set from the far left to right is
going to be your entry wires from your air handler to condenser connections okay it's very important
to remember that if you cross any of these wires during installation you can actually burn the
control board on the indoor unit also before any startup is done you want to check your voltage
at your disconnect and make sure the voltage is what is applied on your label on the side of the
machine as this machine's a nine thousandths of 115 volt if there is a mistake and you put 220
on it you just lost the Machine so anyway just double-check that before you do any startup and
that's the most important part of the wiring on this segment in this section we're going to
talk about how to tighten these lines these are pre flared line set that we're using today and
basically what we're going to do is we just going to put them on here we have a metric Newton meter
torque wrench that we're using and each torque is set per the installation instructions per the
unit so this one today we're I'll show you how to do it we're going to put it on there I've got
a number 17 tells you which direction to go I got my wrench set to the manufacturer's instructions
and we're just going to tighten it up you heard it click it's tight you don't want to over-tighten
these fittings if you do it will squeeze the copper and you'll have a leak from that day
forward these machines are great machines but install them properly tightened with the wrong
wrenches will cause you nothing but a headache from this day forward so we want to make sure this
step is completely followed through if you don't have a torque wrench it's not very expensive we
use a set made by CPS I don't think it's no more than 100 and 100 a half dollars somewhere in there
but I'll show you how we do the large fitting here click that's tight enough and you always want to
use a backup wrench if you don't you can ruin this fit in here so use a backup wrench put your Torx
on it and you should be in good shape we do the exact same thing at the air handler down below in
this application it's very dark so we can't get a good camera angle so we'll show you here basically
we do this now next step we're going to hook our nitrogen to this machine pressurize it leak test
adjoints here and at our area under do double check make sure we don't have any leaks and then
we'll go into the vacuum and step ok here we're going to pressurize the machine with nitrogen and
double check for leaks so I might pull the cap off comes with machine install our 4k adapter
make sure it's good and snug sometimes the valve core don't depress all the way
because of a new adapter or either you know an old adapter one of the two but just make
sure it's a good snug that way you pressurize it and able to read pressures throughout your
gauge right so now that's hooked up this is open I'm gonna go ahead and cut on my
nitrogen tank open all right and we're going to start introducing nitrogen into the system and
we're going to pressurize it to 200 pounds of psi right we have our system pressurized with
dry nitrogen it's been sitting now for about 10 minutes at 200 psi hasn't moved at all and
then we took soap bubbles and we just sprayed around every connection and ensure we don't
have any leaks so we did this here and it the air handler and also made sure it held oxygen
so now what we're going to do is turn our tank pulp just connect any connection and we will
blow out the nitrogen in the system okay now we're going to start the vacuum procedure of
our machine going cut our light on better gauge is set on for 10 a we have a vacuum pump hooked
up center line to the center of the manifold out of our manifold off a high side port to a
for 10a adapter on to our machine so basically now what we're going to do is cut on our pump
make sure they're fully open over the high side now we're going to start the pump down
to about what we want to do is pump this down into a vacuum until it hits 500 micron once
it hits 500 micron we know it's in a true deep packing we'll cut the pulp off okay we've been
pulling the system down into a vacuum for a couple hours now we've got the microns way
down below 500 it's 329 and we know we're good so what we're going to do is go ahead and shut
everything off getting ready to open up free online dump the gas into the air handler all
right now we're at the stage of releasing the freon into the indoor air handler and
double-checking all of our steps and finalizing the installation so next step is we want to ensure
that we have proper voltage on the machine so before I let release the freon and power it
up I want to use double check my voltage and I'm checking it at my disconnect which I got
one 21.9 voltage double check put my disconnect back together and we're ready to release the gas
very important step here and things you need to remember is that everything on these systems are
metric even the allen keys so if you don't have the right allen key don't use it if they round
off then you've got a machine with a rounded off service valve so it's very important that your key
is very tight and it's a metric on this particular machine here you're running a 5 so 5 goes on the
suction line and we're releasing the gas and you
back it off completely all the way all the way back
and discharged lime is a is a five
okay and all the way back and that's it they're not real hard to turn back so if if it feels
like it's hard double-check your wrenches and make sure they're 100% right I have seen people
around them off before and it really destroys the system so proper tools and proper technique
ensures you have a proper install and a good long-lasting system only thing left to do here
is we have to power it up we put the disconnect in the distant disconnect holder shut the lid a
few more things I want to do to the system of one take some foam I want to cover this line
completely to keep it from dripping I'm gonna do the same thing at the air handler and around the
hole I made in the air handler I want to seal that with insulation and make sure there's no
intruding air from the backside of the air handler other than that on our next segment
we'll show you how to start up their handler and show you the features of ductless air now
we have the installation complete on the dozens here nine thousand here we have the registration
card red fill out it basically gives you all the details of the registration card on and some
of the most important ones you need to read the card before you get started make sure before you
even start you have all the proper tools let's have a poster license number and all that for
a warranty purposes this must be filled out so I'm gonna fill it out right now and then for is
the Machine after run it we it has a pretty cool option on a forest fan speeds basically the fan
speed has several different operations we could put it on mode button and operate the fan here
that's been coming home so basically one of the neat features of this machine is we have a 3d
airflow which allows us to operate the swing we've a swing on the remote now the swing is
automatically up and down you have a neutral swing which is basically the bottom of the swing up and
down and we have fixed flings so we can stop it where if we want and just blow the air in that
direction and on the 3d airflow we have a side to side control so if we wanted to go to the right
to go to the right just by matching airflow and it will do that until we measure air flow again
and now it's constantly changing - right - left right left so it make sure it covers your whole
room with 3d airflow which is one of the neat features of this machine not all machines have
very few do and that's it and you can hear it so quiet you can barely even hear right
