How to install an A/C UV Light Kit | EASY Step by Step

[@danpurnell802]

A Very Big Thank you - enjoyed the step-by-step Installation- I'm installing 2 lights, first with-in the Acorn & the 2nd in the return. I up the breaker from 35 to 50 and using 2 Transformer for the UV Balesters.

[@jnava5567]

Thanks for the great step by step video, but I have one question. In the secondary wires, is there a hot or it can be connected to any wires on the light fixture wires.

[@derrickgray3114]

Installed one at my customers home with similar setup as you had to remove because the ac filter lights up blue from the reflection off coil

[@josephli7260]

Im trying to install 3 lights into my unit. Do you need a separate transformer for each light?

[@DeaninItYourself]

no

[@aho9664]

Good video bro i have to of them in my AC. One in the air handler and one in the duck work

[@DeaninItYourself]

Nice 👍

[@miguelangelgonzalezcanas7177]

did you use 2 transformers?

[@miguelangelgonzalezcanas7177]

Hi, If you want 2 lights, one above and one below the coils? do you need 2 separate transformers, one for each light?

[@DeaninItYourself]

One transformer should be good

[@cameronharris2862]

can I use the same 24v wires that go to my humidistat and splice? Or do I need to add another transformer? Thanks

[@DeaninItYourself]

As long as there is not a big voltage drop you whould be fine. If not just add the transfomer

[@bactran3714]

By wiring the transformer directly to the power in, do you intend to let the UV light being ON all the times even when the thermostat sends the signal to turn off the system, is it correct? If so, will the UV light have a shorter life?

[@DeaninItYourself]

yes that is correct

My Carrier Unit is a 208/230. Which Wires do I use?

[@DeaninItYourself]

Red and white. Use the one for 208

Recommend adding note (and product link) about UV safety glasses around these lights.

I am thinking of installing an HVAC UV light inside my supply duct in front of the coil. However, my supply duct has some type of thick black insulation inside of it. I am concerned this insulation might degrade over time due to the UV light. Also, I was wondering if it's OK for hot air (when heater is running) to run while the UV lights are on. Thank you.

[@DeaninItYourself]

Yes the hot air running is fine. The UV lights are designed for this. As far as the insulation goes , I am not sure about this.

[@ApothercyCold]

Seems like you'd be better off wiring it to power on with the unit. Or, do it this way but utilize something like a Shelly to have it power on (via Home Assistant or something) only when running.

[@DeaninItYourself]

That could be an option as well

[@dcs4555]

now you have installed that at the back of the plenum. and the wire goes through a hole with no cable protection. jeez you seem very confident though, i agree on your intentions. just please let everyone else know this is not the best way to install it. i haven't even installed mine, but wanted to know how/why the magnet, and where. now i see how the supplier intended it to mount. and i don't have a metal duct, i have that sheetboard of insulation. so i'm still working it out. as always, just mho

[@dcs4555]

ok i guess that was premature. now i think this device just uses the magnet for a metal plenum. but the bracket has mounted studs, with thumb nuts (i hope that makes sense) for the actual BULB mount. and the magnet is for a metal plenum. i will probably use a metal square to sandwich on the fiberboard insulation. but the 24 transformer - i hope to not need. according to my hvac paperwork- i should be able to use the inside blower circuit. i may be wrong! lol but so far my plans are to go with the 24v common (denoted "C" wtf - online says blue/black/brown/purple) and cool stage 1 (yellow). so we'll see i guess. that should make it light up only when the indoor fan is running. but i did not look into the max current for the hvac 24v circuit. so that might be a prob. just mho

[@Alexsjusa]

Well what a surprise I’m looking into UV lights and if I should keep my UV light from my unit I’m about to replace. I remember you, Steven’s friend! How much are those bulbs. My AC company is saying they are about $400. How much is the entire system?

[@DeaninItYourself]

you can get them on Amazon for around $100 or less

[@Alexsjusa]

@@DeaninItYourself they ‘threw in’ a new system for an extra hundred dollars. There are 2 lights so I’ll see how it goes

[@antok86]

What model air handler is that? Mine has 230v

[@DeaninItYourself]

its a carrier

[@antok86]

@@DeaninItYourselfmy carrier unit has an existing 24v transformer can’t I just tap into that?

[@neonnight34609]

​@@DeaninItYourselfI also have the same question. If my unit has 24 volts can I tap into that?

[@EduardoFuentesLeal]

230 use the 240v cable

Thank you so very much

[@DeaninItYourself]

You are so welcome

[@clintgray1623]

Drill the hole bigger and screw it in from the front, lots easier access

[@malcolden7788]

Also why is the magnet placed on the back wall instead of the front wall? Less wire exposed inside by placing it on the opposite side.

[@ShotByNikoHD]

I wouldn’t put it under the coil.

[@DeaninItYourself]

why not
