Thank you so much. I’m installing one of the systems today and this is giving me such confidence to go into it. It will be my first walk-in cooler install.
The more I watch the more confidence I get to work on refrigeration equipment. Great content my man.
Dave is the the man!!! I thought he went part time on us. Lol, we miss your videos brother, you have no idea how much your helping people in the field. Need more people like yourself, making videos, it really helps when we get one of the messed up jobs, we can't figure out. SUPER TECH BABY!!!!!
Thank you
Love the cardboard tip. Learn something new everyday👌
I appreciate the info on slip and the nozzle. Not a refrigeration guy but I have seen those and wondered about them. Great video.
Gonna be working with a company doing more refrigeration Dave, thanks for another great video as always, your content are educational, fun to watch, has tip of the day, and you teach from old school to new school stuff. Thanks Dave 🤙🤙
That makes life easier awesome job Dave 🤙🏻⚡️🤙🏻⚡️.
Thank you for this. We have been using Trenton Preassembled Evans, which are very convenient. However, they are changing over to electronic TX valves and pile of computer stuff.
I may start building me own. Liking and saving this one!
This isbthe second video I've seen of yours Dave. Flippin awesome. Loved you adding the wiring schematics and modes of operation.
thanks for watching.
wow. you are such a bad ass. So helpful. I just ran into a Bohn and I was a bit confused with no wiring instructions.
I like when you do these instructional videos. Most of everyone one that watches are in school or green to the teade. The rest just love refrigeration.
great explanation of the nozzle
thank you great explanation for an HVAC guy, keep up the good work.
Nice an clean, pretty work bud
Nice work Dave,
Thank you ( Dave ) 💯 x 💯 Excellent Videos
Great video! Thanks for the explanation on wiring,and the orifice before theTXV
Nozzle 😂😂😂😂🤘🤘
Correct Nozzel👍
The company I work for isnt technically a refer company, but we have customers that have refer equipment so we take care of it. I’ve become a damn efficient refer tech from watching your videos dude. I take care all things refer now, for the company and I do refer calls on the side. Thanks Dave
Great complement Rey thank you. Passing on knowledge like the old timers did for me is my channels Purpose
Aahhhh..the leaking coil jobber.. that was a quick turnaround. Stay safe and be well brother Dave
That's totally awesome dave great work 👍
Thank you
Thanks for the lesson bro!
Thanks for the video man really helpful just on the light saving part sometimes it depends where it is going to be installed like in a walking cooler gotta be on 24/7 and on high speed.blessings🙏
this reminded me of how years ago. How i learned the hard way that solenoids are one way
As easy as 123! Thank you Dave.
I was told by a Rep years ago that the nozzle “focuses & stabilizes “ the liquid refrigerant flow. I like that plastic cover on that unit. Keep smiling.
Love your videos Super Dave!
And I might as well be the first to say it....Nice hiss
Good job!
great information hvacr mechanic
I just put in a Bohn like that, I got called back. The fan plugs are loose and they just hang, had to strap them. 👍🏽
Normal Dave allows "Quoters" in this feed?
Guess that's 2021 for ya lololol
Just just giving ya unnecessary hate. You're good bro
Thank you for sharing👍
Excellent video 👍👍👍
🤘⚡️🤘✨
Sweet pretty job brotha 🤘🤘🇺🇸🇺🇸
good job!
Your video rock man
Thank you
Pro tip: Home Depot 6in1 screw driver goes in nice and tight in that 1/2 pipe when pushing the nozzle and o-ring in
Did a few days ago. Good tip.
Good one Dave 👍
Thanks Greg
Awesome!!
Min 20 i tough you had someone looking at you while you were brazing the solenoid valve and expansion valve 😀🤭. Looks good my only concern with those plastic hinged covers are if my clumsy azz would get too happy with the torch and melt it 😂😀
They are removable.
I still think for a medium temp box or reach in. The evaporator fan motors should be energized 24/7 365 at their maximum synchronous speed.
Forget ECMs for refrigeration. The replacement parts are expensive in comparison to the energy saved. Even some of the fan brackets don't even let you use a PSC or shaded pole... So the customer is the one to suffer especially if it's not in stock. This world is backwards
Love my Klein crimpers
I know a guy who installed a piston with a TXV on a residential unit and he spend 5 days troubleshooting the system lol
Not the same thing here.
I do transportation refrigeration, we had a coil that was slipping apparently, we never have to mess with stuff like that so we had no idea, once the coil was removed we found that the nozzle was loose just rattling around, made the coil ice up
To each there own but I usually get the prebuilt from Trenton/United.
18:46 - I’m disappointed that we didn’t get to see you twist that TEV up and around into position! D…, D…, D…!
First. Greets from Germany
I'm not of fan of 2 speed for air defrost. I jumper t1 to k on the terminal board to bypass it and get full fan speed.
End of the earth 😀
I’m #420 for giving you a 👍I think that deserves a free NorCal hat💪
🔥🔥🔥
I like the switch on the back, so the sticker is right side up while the blower is upside down?
Thanks for the video, I attended two calls, the problem solved, but in both services the evaporators have distributor, the lower part of the distributor make more ice than the upper part, do you think in both evaporators the nozzle is missing and one section of the coil is receiving more refrigerant?
good stuff man!...but what kind of thermostat do i need to activated the high speed of the blower again?..i replaced an old evap with similar product just has 3 blower fans.....there's 2 evaps for this system so they used just 1 solenoid to feed both evaps and thermostat is on the old evap...i wired 115 V only to T1 and T2 , blower fans run on low speed ,don't know how to field wire to utilize the high speed.....a little help would be appreciated! thanks
👍
Yes The first time I wired that fan relay with the solenoid wrong, I said ok I wire them in series. Big mistake, electricity 101, relay coil was getting energized and changing fan speed but magnet on the solenoid was not enough to open.
i just remove the black wire on the relay and run high speed.
Don’t the nozzle also help with flash gas feeding into distributor??
Where do you run the other two wires going to the clock?
Waw
Almost looks easy!🤔😃

Stay safe.
Retired(werk'n) keyboard super tech.
Wear your safety glasses.
What heat blocking compound are you using here?
Not a fan of those plastic side panels on those evaps now.
Can you please let me know , we have walk in freezer room there is ice forming on floor ,roof pannel side wall also near Evaporator unit ,
Door heater is working also air curtain are installed,. No door switch installed,
Dixcell controller is installed.
So basically what you're saying when it's not, ground any have a call compressor and cold air it goes from 1:10 low speed to 2:20 High
Quick thought dave now with that new 2 speed fan would the differential on tstat have to be more to accommodate for the lower fan speed during defrost ?
That’s possible
@@NorCal-refrigeration very interesting with these
I wonder "Air Defrost two speed motor" at 6:50 we can choose either 115v or 230v and are there any changes here. The fans could work both voltages 115v and 230v? and what is the part number of the solenoid? I need help. Thanks
No the fans are either 115 or 230 depending on which you order.
@@NorCal-refrigeration Thank you. I understand. One more question is how about the Nozzle. I cannot understand the chart attached. My compressor is R407C, what nozzle I should put in_ L 1/2 or L 3/4 . Thank you in advance.
Would not using the nozzle cause iced up distributor tubes to the point that it turns into a giant block of ice ?? Medium Temp 407A
No
@@NorCal-refrigeration well it looks like I've got another problem lol. Thanks for the videos bro 👊🏼!!!
What happened to the super tech symbol. I can't find it . It should be a certificate that you hand out to your RUclipsrs. Great video you just put out. Believe it or not I got stuck on that same coil, because the wiring diagram was ONLY IN CHINESE!!!! DA FUK!!!!
Where's part 2?
12:36 Difusor?
That is why they call you the “MASTER”.
Those coils with the plastic side tanks like that are cheap as heck. 8 out of 10 times you can't even get it mounted without the drain pan getting just all bent up
Those plastic side panels I don't trust
The blue plastic doors look cheesy and cheap as shit.
Guess every manufacture gotta go cheap now days with all this free money everyone’s getting the economy is dog shit.
👍
Thanks for the great info.
