Build up a coil and go over 2 speed evap Fan wiring. Talk about nozzles and txv selection for coils. If you would like to buy me a cup of coffee www.paypal.me/... #refrigeration
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
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!!!!!
11:14 - “Who is it?” . . . “Dave’s not here!” 20:19 - The Neutral is the ‘ identified’ conductor. Good call, Dave! 21:11 - You didn’t mention it here but only use the teat on non-insulated crimp connectors.
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
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 😂😀
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.
What happened to the super tech symbol. I can't find it . It should be a certificate that you hand out to your RU-vidrs. 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!!!!
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?
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 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
@@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.
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.
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!
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.
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 🤙🤙
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🙏
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
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
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.
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
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 ?
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.
