Basic walk in freezer wiring

Can I use a 8145-20 time clock to replace a 8141-20. I know the 8141 has 2 nc contacts but the freezer seems it only needs the cooling and defrost only? It’s a norlake old capsule type WI.

Great video, but i have a question.
Where does the control voltage go to the contactor? From 4 and n from the defrost timer?

I just lost all my hair watching this. U explained it good but still confusing.

Thank you for this video.
When you say, that activated "half of the evaporator fans" and then the "fan delay activates the second half". What do you mean by that? All 3 fans run at lower RPM (half speed) first and later on at full speed? Or does it mean that only half of the fans run first and the other half do not at all but only later are turned on when fan delay has reached 35°F? So, do "half fans" refer to lower RPM speed or only half of the fans are running at first stage?

Thank you. It is great, and easy to understand besides that English is a second language for me.

So in defrost mode there will be refrigerant in the evaporator coil?

A true professional. Great work

The outro song was hitting harder than 480V my guy 😂

THANK YOU SIR

excelente

What do you love the burgers???

I love your video learning series but I can’t understand what the hell you song is saying in the beginning I don’t get it

What if it don't go to 1 but "n" and " x"

Can't wait till next week I start this topic in school I'm gonna be so happy when I understand it ....

Beautifully explained. So useful

I definitely got the evap side of it but how does the control voltage get to your contactor up top? Am I bringing #4 from my defrost clock up to one side of the coil voltage on my contactor and the other side goes through my low pressure/high pressure switches?

Great video!!

This really is great,straight info from a guy who does this everyday.I know really smart people look at this and think so easy,but since I'm not so smart,it seems complex to me.

Where can I get 240v to power the A421 when converting from mechanical and the defrost clock (terminal 1) is on the condensing unit? Seems only N is always energized. I've been having to feed in a neutral and run the stat 120v but wish could just use the wiring already available in the freezer evap.

I love you. thanks

Now throw in the K2 control🤮, all my supply houses sell them with new boxes, hated them at first, but saves a lot of time

great explanation.

Yea

Much appreciated! I am in my last semester of hvac school and we have a walk-in freezer that hasn't run in years. We have a new instructor and much of our training is self taught. This video should help our group get this mistreated freezer back online! lol

I believe this was the video I was inquiring about🙏🏾

thank you for you video. I have a question for you , most of the time on the job. who is responsible for wiring the timer and the evaporator coil. Electrical contractor or mechanical contractor. thank you sir

Covered this in trade school a lifetime ago, but with no "hands on" experience, remained a bartender for far too long.

Had been in F&B operations for 35 years, barback to management, got bored with pushing paper and for the past five years to chase the blues, as a sideline distraction, have been more or less handling most of the fridge work, (with varying degrees of success and flaming failures) at a horse race track / music venue where I still spend more time pushing paper.

Attended Bryan Orr's first symposium pre-pandemic and met Dick Wirz.

40 years later...watching your back of a cocktail napkin scribbles with free verse keeping it real rambling video has connected more of the dots between my ears than any of all the above.

Be well amigo, would love to ride shotgun with ya one early morn!

I'm installing a condensing unit with 2 evaporators. Can I wire both evaporators to the defrost timer or do I need to go through contactors ?

OMG BRO IVE NEVER HEARD YOU SING BEFORE 😂😂😂😂💯💯 THAT WAS BAD ASS LOW KEY😂

Thanks for this great information . I learn a lot of this . But i need some information how to wiring the reach in freezers because it has a lot of relays and controls

Well explained! Simple, easy to understand. Spoken like a good journeyman! Thanks!

Awesome video, thank you

🇹🇷🤳👍🛠️ nice Job

Funky munky explain thats it ….

Where would you wire in your condensate line heater in this application?

Great, now demonstrate one of these new improved computerized marvels !

Thank you for the vid Dave!!

😎. Thank you so much.

Fantastic!
Thanks for making!

Good video thanks

Bro this was so awesome! I now completely understand basic freezer wiring. Thank you so much. :)

Good video Dave. Can you do with a 3 phase condensing unit.

great job of explaining that one !!!

Nice video I need to wire up a evaporator coil tonight and I don't know how to do it but you're giving me a good lesson

Favor bro can you make a vedio in condencer. thank you

Nice setplay bro..

Thank you so much for this great information. I have a question about reach in freezer box the wiring box before to the main control in the condeser. Some relay and a control of wires

"In the funky monkey lamest terms"😂😂
I understand
Thank you for making these videos to help new techs like myself

Another schematic you nailed it
