Okay thanks for clearing that up for me. Here in Canada those valves may be more common. So the txv still primarily takes care of the increased load demand in the cooler itself, and the headmaster just maintains minimum required head pressure in extreme low ambient temperatures around the condensor. Thanks for the video and explanations. Kevin
Absolutely my pleasure, sometimes they shut down a fan on multiple fan systems or just cycle the fan if they only have 1 fan.
Super stoked to have you back, Rick!!!
Thanks Kenny! I live for the feedback from the viewers, I'm not perfect by any stretch, I'm just willing to go out on a limb and take a cut at it. I appreciate you hanging in there👍🏻
Absolutely love how organized you work 👍🏻 Can’t get over you saying the word poosh lol love what you’re doing keep it up.
😂 yeah my grammar isn't the greatest. Thank you for the compliment, I'm glad you enjoy it👍👍. I appreciate the feedback🤜🤛
Yeah, headmasters are easy to understand. Yet they are misdiagnosed often. Good job bro.
Only one way 2 learn, tear that stuff apart! Thanks 4 watching!
The controller cycles 3 times at start up to get any liquid out of the crank case. 🤘🤘
Figured as much, but makes you wonder how it would have liquid in there if your pumping down. I assume there trying to cover there bases against bad installs?
Was doing the F&B operations of grand opening of a new OTB parlor. Walked around back and saw brand new condenser coil on ground near gutter downspout caked in leaves and crap. "Hey I'll do them a quick favor". Pulled disconnect and cleaned it up. Plugged back in and freaked out at how the unit was starting and stopping! WTF!
Glad to see you back Rick! Hope the name change means we'll see more of you soon.
@@davejohnsonnola2758 this luckily had a sticker stating that it would do that, it's a nice controller set up, I'm curious to see how it holds up outside, kinda weird it didn't have a defrost and thermostat built in as well. I've missed doing these, even though it's a lot of work and with new equipment upgrades, even costly. (New camera, computer, software, etc. but it's rewarding to hear from everyone. )
@@sjefoekel6058 I noticed it didn't seam to do it everytime, I didn't stay around for multiple cycles and have only been on this model maybe twice.
.oO( or cook the relay/contactor thrice as fast) which one is the real reason or an excuse :))
Your channel name was the only thing that changed, same good intro with the same great quality videos👍 Just don’t make me wait several months for another video. Lol
I've got three or four other ones that I have. Just need to decide which ones next.. if I could have done them sooner I definitely would have. I appreciate you sticking around all these months👍🏻👍🏻
Great idea with the bucket - I just ordered the Plano bucket topper for my 1/2” Appions & vacuum setup
It makes it so much easier. 👍👍
Jawa Tengah, Indonesia On, 🤝🙏
Welcome back brother!!!! Soooo glad you came back !!! Can’t wait for all the new uploads keep on making fantastic content
I'll try my best, I have to be on my best behavior or I'll be in the dog house again. Lol
How great one of my Top Techs has come back. Glad to see you again Rick! 😎
I don't know about great but yea, I currently see light at the end of the tunnel. Thanks Juan! 👍🏻👍🏻
This guy packed his tools precisely the night before lol
🤣 👍👍
Super video! I can't believe it was installed with the crating directly on the roof
Yeah we're not going to go into that. Let's just say it wasn't my idea. 😏
Good Video. Happy Hvac'n.
Thanks working man👍👍
Good to see you back at it
Thanks Nicko! Good to be back!👍🏻👍🏻
Awesome!! Happy to see you are back!!! Great content!
Thanks Justin! I appreciate you watching
text book refrigeration work, keep the videos coming excellent content
Thank you! Thanks 4 checking it out.
Thank you for your teaching
+Sal Castillo Your welcome Sal, I'm glad your able to get something from them. Thanks for watching!
Welcome back Rick
Thanks, Rodney! I've been trying to get back in the swing of things again.
Glad ur back! Great vid
Thanks Jacab! Me to!
Hey RICK!!!! Good to see you again! Been looking for your vids brother! Great detailed explination of a Headmaster with tear down. Great explination. Nice work!
Thanks Mr. Freedom, I tried to make it informative without overload or boring. Lots of editing to go from 45-60 minutes to 12.
@@HVACRSurvival No doubt there's a bunch of work there Rick. I'll DEFINITELY keep the "RICK STORE" for my Amazon purchases at the ready, I'm happy to support you any way I can. I'm looking to add the VP-85 here soon, and I'll see if you have that link! Be an honor!
@@crforfreedom7407 amzn.to/31K8Qqa This is the link to the 8cfm fieldpiece pump. Any problems with it, let me know. Thanks again!
Awesome video, thank you!
Thanks for taking the time to let me know!
Welcome back!
It's great to be back! Thanks for watching!
Great video- thanks
Your welcome Mike!
Great Video, Thank You.
Thanks RJ! I'm glad you liked it.
Great thing about these videos, is they show our real world problems, I don’t like the reuse of refrigerant though
I try to use new for most repairs, except for R-22.
Bacho have an even thinner one. For example the 9031T
I have seen them, they look ground down on the tip area, I haven't had any problems with the width so far doing what I do. Thanks for the heads up
nice work
Thanks for watching and the feedback!
Nice job
Thank you! 🤜🤛👍👍!
They don't call you Survival for nothing ... Lol ... Welcome back Rick ...
I needed to change it up a bit and it just fit. It's a jungle out there, here's how I survive🤷♂️😁
Good vid.
Thanks North! Glad you liked it.
Where do you got that lid for your bucket ?
Amazon. I can put a link to it when I get home.
Im with you on that. If I can break down the piece and sweat it in, not worrying about overheating, eliminates a worry. Then you just have the concern of not getting solder into a threaded joint you need to thread together afterward, or seals. Then again, when you break em down, those teflon seals don't get damaged.
I was more worried about the diaphragm possibly rupturing and getting the nitrogen through the valve. Thanks 4 watching👍👍
@@HVACRSurvival doesn't take much to pop that baby
@@hvac01453 I've only changed 2 of them so I haven't had the opportunity to destroy one. 😁
I had a job up on a roof I work at a school district so I get do a few things, I replaced the Headmaster three times and I did not burn up the valve it would not operate properly it would just let Hot Gas bypass. So I cut it out and it's put a fan cycle control on there and haven't had a problem on this walk-in cooler ever since didn't fix it by the book but that was Headmaster valves can be a real pain in the ass
Thanks for sharing that Ben👍 That's interesting, was it a Sporlan valve?
@@HVACRSurvival yes I changed another one out on a multi compressor unit, and the replacement worked fine. That system because of multiple systems in it, I had to have a headmaster for low ambient operation. That job the new headmaster worked great. I always use heat stop with wet rags. Don't know why the other 1 f'd me. Still working ok using fan cycle for low ambient operation
@@benkuxhouse787 interesting👍👍
You got new boots 😂
This is from 4 years ago 😂 they probably were new then.
Weight 10-15 % for winter
Please do more videos
Keep watching👍👍
Those power swagers look like the ones from my impact flare kit. Are they pretty similar? Gotta replace another one of these coming up, fun fun fun.
I use the spin swage brand in the video.
Do you add any nylog to your threads when installing the new one?
I usually use it more for the friction points on the flare but someone's I'll put it on the threads, (I also will use a white locktight on only the threads if it's a special case but not the mating surface, EVER.) The nylog is just a oil, I don't believe they're is anything wrong with it. ( But any locktight or leak lock i never use it anywhere but the threads. )
Is that in addition to a pressure controll for the condenser fans or does the headmaster valve pretty much take place of that feature.? Curious, maybe it has both?.
I normally see one or the other but there is some instances where I have both items.
Those look like the knee pads I had that were Amazon top pick
👍🏻That's where I got them, there not holding up as good as I hoped, there called "no cry"
@@HVACRSurvival thanks! I lost them recently, so maybe I'll try another then, thanks.
Alright alright alright!
Hell yea!
Here in Arizona when the head master fails we clip the capillary tube.
Same here but there was more to this job that I couldn't do into detail about.
So this controller helps to maintain pressure in unusual low pressure situations?
Correct, it's job is to keep a minimum head pressure of what it's rated for, in this case, 180 psi. This helps keep the refrigerant pressure high enough to maintain the pressure difference needed to run the txv. These only work in a system with a liquid reciever.
Finally!!
I know... Right. 👍🏻👍🏻
You bums who put a thumbs down are losers ! Great content my man . I’ve been at this for 21 years and it’s nice to see this stuff out there for the young guys
Thanks Mike!
Agreed, 41 years in the biz here, great video
Dumb question but why is the headmaster needed in the first place? Is it to help keep the liquid refrigerant in the reciever more fluid so it can make it back to the txv? I understand it's to keep the head pressure high during colder months of the year, but why is that needed?
It keeps the head pressure up during lower ambient temperatures. If your head pressure drops so does your low side pressure. That can lead to feeding issues to the TXV and coil freeze ups
Why sometimes it restricts refrigerant get into receiver? I put a lot refrigerant in the system and tried to bring the suction line pressure up, but all refrigerant just all went to condenser coils. Thank you
If I suspect that it's not working correctly I'll pump it down and check the level in the receiver and check the in and out temps of the valve.
HVACR Survival thank you
Is it Banco? The wrench. I need a good, wide but thin wrench.
That's it. Is this link if you want to support the channel, it's the same price you can get it for. Thanks for watching! amzn.to/3JTA4Tm
What’s the name of the bucket tools compartment organizer if you response thank u
if you use the link you'll help support my channel, yet still pay the same price. amzn.to/40edI5l
So if the Receiver becomes starved, the valve opens to allow some liquid to go directly to the Receiver from the discharge ? Would this happen in high load conditions usually...such as filling up the freezer or cooler with a big new load of food or beverages? Kevin
If the receiver becomes starved of liquid, the TXV will also become starved as well, this is why you have to have the extra 10 to 15% for the winter charge, it doesn't substitute an improperly charge system. What it's doing is allowing hot gas to come into the receiver and mixed with the liquid in the receiver to maintain a constant minimal head pressure. If the refrigerant level is low then the system's going to starve the txv of liquid. These systems are also referred to as a flooded condenser because you're actually backing up refrigerant into the condenser in addition to what's in the receiver.
10 -15 percent of what ? The total change I live in Canada and this is something I struggle with. Or another example let’s say you go to a service call during the day and find that it’s low on gas and charge the unit to a full sight glass and pressures are good. How do I know how much extra Freon to add for low ambient temp ?
@Jerome, yes of the total charge amount, if you don't know for sure what that amount is then you can less accurately guess what the total is and calculate it or pump it down into the receiver available warm it up with a heat source to see if you around the 80% mark.
Do the 3/8 hoses have 1/4” ends or do you have some fittings you use to hook them up
The TruBlue hoses have changeable ends, (1/4",3/8",1/2"). The Appions have to be purchased how you want them.
HVACR Survival thanks for the response. I was actually meaning to ask about the 3/8 charging hoses you use for recovery
Ok, yes mine are 1/4 on both sides. Your welcome 👍
HVACR Survival I’ll have to grab some!
Would you prefer the chest mount or head mount?
For recording? Chest mount, it's hard to tell where your recording when it's on your head.
HVACR Survival Thanks! Seems like it might be kinda funny walking around with a chest mount but makes sense.
Do you really think something on your head would look any better LOL either one's going to look Goofy. when you're wearing your jacket it's not so bad. Otherwise you got to wear it underneath your shirt and poke the camera out
HVACR Survival haha well on your head might kinda be like a head lamp. Wearing it underneath your shirt and poking the camera out is a good idea. 👍🏽 I wear a button up so that could be pretty discrete.
I’m Canadian, why do American refrigerant jugs have to be turned upside down, ours have a liquid and vapour valves built into them
Our recovery tanks have a dip tube on the liquid but none of the throw away tank flavors I use do. I remember one or two manufacturers use to do the tubes but because it wasn't a standard across the board it caused confusion resulting in a bad mix, so I assume that might be why. Otherwise it might be another goofy government B.S. regulation that you have that we don't?
Are you back to making field videos again? Enjoy the video
To the best of my knowledge I am but with guidelines.
👍🏻🙋♂️
Thanks for watching Gene👍👍
The condenser not the HEAD MASTER
Redwing boots
Yep.
Poosh?
Welcome to the channel.
poosh lol, awesome videos but your pronounciation of words that start with pu is pretty funny lol
😂🫶
run for a few seconds stop repeat repeat repeat, aka contact/relay eaters....... not to mention motor stressers.....
Why is it still on the skid?????? Master built is cringing right now??????
There's a lot of complications and variables outside my control. I'm just demonstrating the installation of and how a headmaster works. 😉
Lol 😂
Cant see much of anything
What more did you want to see?
@@HVACRSurvival sorry I just meant that the cMera angel was off. Otherwise an informative video
Gotcha, this was one of the first videos I made after getting the ok to record again. I didn't want people at my company saying I was wasting time recording.
