Once you get everything wound down hand tight which is your unit everything looks clean everything is where you want it now you’ll take your wrench and you can snug each connection up I’ll start with the far side get this one let’s be super tight just good and snug you can feel it now if you want to I’m gonna go ahead and show you on a backup if you’re gonna back this up you can back it up with a set of chanteys a little tighter you can bottom it out nice and tight channel locks back up nice and now we’re installed tied in completed ready to roll now in this case I’ve got to turn the main water on.
I would be turning this valve on to activate the unit that’s unit off right now so if we’re gonna activate we would just pull this valve into the run position pull this valve into the run position and now we’re operational there we get into our operation instructions as far as how does this thing work well right now you’ve got this handle is in the run position if you look closely at the valve you’ll notice there’s a word run on the valve itself that word run is just telling you it’s confirming to you this is in the correct position it also has an arrow showing you the direction of flow so your direction of flow is coming into the unit because this is your inlet for your tankless water heater home depot unit then you’ll notice this third symbol here right in the center which is basically a representation of the ball inside of here telling you the telling you what is flowing and what is not flowing and showing you.
Where your inlets and outlets are basically the ball inside of this one is it telling you direction as low as going this direction the ball is in a position to where it has an open on the backside but not on the front side so that tells you this front side is closed and there’s no flow on it which is exactly what you want same thing with the hot but the hot is reversed because it is an outlet so the water flow on this one is coming out of the unit flowing through and here’s your arrow and here’s your little word run again jumps out at you in the run position so you can read it very clearly now again you have your position of the ball and again the ball is showing you that.
I have flow coming this way plus we have pressure on this valve which we need to have because that’s the safety valve so when it’s operating that is necessary that you have pressure there now if we want to go into a flush position we wanted a service unit first thing we do is confirm it’s in the run position and gently take apart one of these caps and there may be a little bit of water in there but in this case there isn’t you drop that down do the same thing with your cold again aware there may be a little bit of water in there and we’re cleaned so that comes off now you take your hoses and you simply have to regular washing machine hoses is all you need these ones are stainless steel they’re steel braided a little nicer but again it doesn’t really matter rubber ones are fine on like this on and again these you want to make sure these are good and snug and they have a hose washer in there a gasket it should keep it fairly watertight so you get very minimal amount of leakage off of it but you dump those into your bucket and from there now the only thing left to do is turn it into a flush position so to do that.
What you’re going to do is you’re going to turn your hold position hold valve first pull it up into the flush position where you read the word flush and now what is done is it’s shut off the flow of water going in so there’s no flow coming from here into the unit and it’s allowing all the water to leak out or drip out or run out through this little line here the hose down into your bucket now you’ll do the same thing with the hot side turn it to the flush position that now reduces or eliminates the flow out of the unit and takes everything that’s inside the unit allows to flow out through this hose right down into your bucket and that is the position you will leave it in through the entire flush operation okay now our unit is all tied in back in back on line ready to work the connections.
That we’ve done here this is flex connections that we’ve used on this they’re very simple very easy you they can look clean but they’re not the most professional the most aesthetically pleasing that you would get like out of a commercial system sometimes you might be required to do what’s called a hard plumbing connection and a hard plumbing connection most of the time you’re going to be using what’s called a Union fitting Union fittings are okay and they have their use and their approve concealed spaces or non concealed spaces and they’re very quite popular fitting but a better fitting that’s out there is called a left-right connector or a union alternative basically this is a new fit II that’s an exclusive by Charmin this particular fitting it works like the old-school left-right nipple and coupling a lot of you older plumbers might be familiar with this particular fitting basically is the same thing as the left right nipple and coupling but it’s a lot more versatile it’s made out of brass it’s approved separator for dissimilar metals it’s approved to install on concealed spaces.
It transitions you from threads to left or it finishes you from a sweat to a left and they give you your breakaway you can also use a reduced juicer in there as well and incorporate that with the same fitting so it’s like a multifunctional fitting that gives you all of the ability that you would have had with the old school left right nipple and coupling but a lot more versatility because it worked with many other things it’s IAP moe approved has a UPC stamp UMC stamp is on that I out my website evaluations zero one four nine if you want to read up more on and as an exclusive fitting available through Charmin very good fitting very tight-fitting if you’re gonna do a hard piping this is definitely the pipe the fitting we would recommend to you well with that said I’m gonna go ahead and let you get off that hot shower I know you’re dying to get into since we’ve gone through all this hard work of figuring out to install our unit so thank you for staying with us enjoy your day have a great one and enjoy those long hot showers.Read More
