I've been looking into buying one of these, but this is crazy maintenance.
Hey thanks for the great video.
This video helped immensely with wiring my system. Thank you 1000 times.
We're very happy to hear it, Rob!
Yes the instructions need to be cleared up on this issue. The cleaning video helped more.
Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) th-cam.com/users/postUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.
Thanks for this video, it gave me the steps to easily clean my unit. I have a problem with my water pump that must be clogged, is it easy to remove it and clean it or replace it? Is it located beside the drain plug ?
This is an excellent video and they held me a lot thank you so much God bless you
Thanks for the positive feedback, Jaime. We're glad it was helpful!
Awesome awesome video ! Thank you
Merci bon travail
I was looking for some help in deciphering the installation manual when I came across this video. My unit came with two extra jumper type cables which didn't make sense (since I didn't need them). This video helped me figure it out, though it's fairly simple to install, but the extra cables threw me off. This video is very well done. Question, does the display plug just pull out or does it have a disconnect tab on it. Looks like he just pulled it out by pulling on the wires.
It has a disconnect tab.
Are cassettes compatible with other brands of condensers?
Very good
Thank you for your instruction. What would be the best way to get specialist to service it. Any recommendations for nyc area?
Hi Dawa, you can try getting in touch with our Technical Support team, Mon-Fri, 9am-5pm Eastern Time, at (786) 953-6706 to see if they have any suggestions for you.
Thank you for this video. It helped me a lot. I just have a question, seeing this type of service, is it no longer necessary to use a pressure washer to clean the coil?
We definitely don't recommend using a pressure washer on ceiling cassette units. It's bound to result in a huge mess and risky having so much uncontrolled fluid around the electrical components.
@@CooperandHunterusa hi I'm from trinidad and Tobago, our service for cassette unit are to scrap everything ie:remove filter, electrical, drainpan Blower wheel,disconnect the drainline from the pump, jus leaving the Blower motor in place, attach a cassette service bag that is suspended under the unit via hooks and adjustable strings the bag shape like a cone a drain off line is connected to it's base, put coil cleaner on coil and flaps/swing on facing n filters, use adjustable pressure washer or small washer on parts n coil, securing the Blower motor with a bag tucked around and wedge behind motor, flush drainline and secure back onto the pump,dry the unit and reassemble. Left working properly. When I come across a service, 1 soon I would upload our service.
Hi, would anyone know what the red blinking light on the ceiling grill, blinks 4 x's meaning? Thanks for the vide, very informative.
Great video. One reason I would never buy these. The maintenance is a pain! Wall mount so much easier. What’s the cost to service this? 🤔
Salut ingénieur, j'ai question a posé et merci de me répondre.
Est-il possible de remplacer une carte standard dans le climatiseur cassette ?
Une fois sa carte d'origine est foutu ?
Wow, going ductless always sounded better from an energy savings standpoint, but that's a lot of maintenance! Are all head units this bad?
Using this to cool a home would need a ton of heads and the upkeep of 3-5 heads would make reselling a home very intimidating compared to simple air filter swaps (and the occasional flush) of a typical air handler. Maybe use of a single head for storage/workshops would be fine or extra capacity for a single room to kept at a separate temperature, but otherwise I'd probably stay away from ductless in a home (unless it's one big room with no doors lol).
I don't want to buy separate air filtration units and dehumidifiers that will take up conditioned floorspace, so it looks like a mechanical room, basement, or conditioned attic with an air handler (maybe HRV/ERV and dehumidifier too) and ducts is still the way to go... dang.
Weldon Very Very Nice Wonderful Good Job
Thank you!
Are these electric or gas? Looking to install one in a 500sqft tiny home.
Can you tell me which way the black filter goes in it went to fast in the video does the smooth side face out and the groved side in
Is cleaning cassette units usually a messy job? Some geniuses put one in a server room directly above the servers and it needs cleaning but no one will touch it because the equipment in that room is super expensive and they don't want to be held liable
It doesn't have to be a messy job. Frequently cleaning could mean that each cleaning can require less water/coil cleaner and, therefore, less risk of a mess. It would certainly be wise, either way, to cover any fragile equipment with a large waterproof tarp for good measure.
Just 2 suggestions for the next generation, First, maybe have the 5 screws black or another color that stands out. Second maybe an intermediate cable that allows for one disconnect for the sensors instead of disconnecting all 4 one at a time.
Thanks for sharing your ideas with us!
Lol! It depends how dirty your coil looks.if it's too dirty dont try this
I had a P5 error code on a Mitsubishi ceiling cassette installed on 10-06-2020 and when I removed the condensate drain pan there was a lot of slime at the bottom of the pump preventing it to remove the condensation. The filter is cleaned often. I have cleaned the slime and it is working now but now trying to figure how to get clorox in drain pan yearly to prevent a re-accurence.
Hello! We would recommend getting in touch with Mitsubishi to get their suggestions as we are not familiar with their equipment. Thank you.
You can research the code on mitsubishi Web site and fix the problem via a a/c dealer or buy it online, since you scrap it yourself then you can go the distance and repair it yourself. When you found the slime in the drainpan, it meant it wasn't serviced often or very poorly, in the islands, we service every 4-6 months.
I got a unit just like this installed to my home (Model CH-FC030K2). I wonder is it normal that it makes a loud motor like noise that has nothing to do with the fan? The noise is constant with all the fan speeds, and even continues for a minute after the device is turned off and the fan has already stopped completely. I'm just wondering what else besides the fan motor is there inside to make the noise?
Our units are very quiet. A loud noise does not sound usual. We'd recommend getting in touch with our Technical Support team for troubleshooting Mon-Fri 9am-5pm at (786) 953-6706
What if the fan is not coming off after taking the bolt off?
Thanku sir
How often should they be cleaned like this?
It depends on the frequency of use and other factors of the location, like presence of pets or pollen. Generally speaking, though, a thorough clean should be performed at least once a year.
Very useful information sir plz also upload a video about daikin air conditioner ( casete type )
Hi Danish Ali. There's no need for a Daikin video on our channel. We prefer Cooper&Hunter :)
@@CooperandHunterusa I understand sir and thanks for ur reply
Actually I m working in Kula lampur and here Daikin is very famous and mostly people use Daikin
But thanks alot for ur reply ur video is very useful it helps me alot
@@DanishAli-ti3uf Daikin is also a common choice in the U.S., but Cooper&Hunter is growing in popularity. We're glad the video was helpful for you!
In the end shots the interconnecting wire was not mounted under the strain relief.
And it would be better to use some spades instead of bare copper under the terminals when installing such a unit.
Hello P van der Kleijn! Great attention to detail! Our communication cable is held into place by a strain relief before it reaches the terminal. And, fortunately, our units are designed so that you're able to connect wires with or without spades. Definitely couldn't hurt to use them, though!
Supper Bro
Thank you!
i think its better to use low pressure water jet pump to make sure the coil was clean and no dirty gell stuck inside it.
Fine
Wow! Great video and very informative! Had a company come out to clean my units. Three in all and they certainly didn’t do what was done in the video. Will do my own from now on.
Side note: one of my units started making a loud buzzing sound inside the area where the electrical components are. Is that a common problem with the 4 way cassettes?
Hi Kellee, we definitely recommend having a professional do perform all maintenance on the units. Maybe have them follow along with the video next time!
If you'd like to inquire with technical support about the noise, please call (786) 953-6706 Mon-Fri, 9am-5pm, Eastern Time
@@CooperandHunterusa after I had the fan out (which the company I hired never removed to clean the unit properly) I could see dirt still caked on the coil and they had bent the coil in places as well because the guy stuck a sprayer wand up there. I’ll never hire it done as long as I’m able to do it. I have before and after pictures and should request a refund.
@@kelleeelmenhurst315 Wow, such a shame. We're glad the video has been helpful for you!
😯 🤔
I am beyond astonished this has got to be the most difficult task to do how does he do it I did it once and fell and hit my head but thank god my head was spared brother be careful while doing this I recommend everyone
Wow - what a story!
@@CooperandHunterusa on point response.
Yeah man
@@CooperandHunterusawell it’s not easy
Thanks
Thanks for watching!
Drablusttuing vedios I am waiting Bro
@@kathirvelmanickam296 Sorry Kathirvel, we don't understand.
how often do you clean it?
Depends on how frequently it is used. But it would be wise to clean at least once a year.
Curious what kind of smell a dirty coil causes. My ceiling unit on cool smells faintly ike a car heater coil overheating. I sprayed coil cleaner but the smell persists. The cooling and heating are the same for 2 years but it always gives off an unpleasant smell on cool. This video will help do a deeper clean. Thanks.
The smell depends entirely on the surrounding atmosphere as, obviously, the unit itself does not create a scent. If you're concerned about the smell, we'd suggest calling an HVAC technician to come out and service your unit.
Much better to use a pressure washer to make sure that the unit was totally cleaned not that.
Very true my brother👍🏼
I wish I would have this kind of ac
What's stopping you from getting one? C&H mini splits are affordable, easy-to-install, and energy-efficient!
@@CooperandHunterusa bro I want it I really do
@@CooperandHunterusa bro I’m soo busy with exams
@@CooperandHunterusathese are amazing lol
very clear instruction, but why not removing the water catchment sink as one cannot access the outer side of the coil and only cleaning one side of the coil.... especially when you are not using a water pressure sprayer, it's difficult to clean both sides by only cleaning from the inside.
Hi Henry, the simple answer is that we didn't clean the outside of the coil because it was not dirty. Since the inside is the return side, it's the part that needs most maintenance. So, it really depends on the application.
In regards to the pressure washer, this isn't as necessary if you use a good chemical coil cleaner. This method also saves a lot of mess, comparatively.
@@CooperandHunterusa given the coil can be really dirty in some cases, the dirt or gunk will be flushing into the water drainage sink if it's not being removed. This might cause a blockage in the drainage and flooding inside the unit... how to prevent that ?
@@henrymug Good question! As we mentioned, this was a basic cleaning to our unit, which was not very dirty. If you're cleaning a lot of dust, etc, from your coil we would recommend the same approach. Brush the coils downward into the drain pan and continue to clean that way, to avoid a big mess. Then, when the coil is clean, remove the drain pan and clean that component separately. Reassemble, and you're good to go!
@@henrymug I prefer to vacuum first carefully if real dirty prior to water flush. Handheld Dyson.
Why not cleaning of pump motor ? ...
1:21 wait a minute...so the water condensation doesn't drain anywhere until you unplug it?
Yes, there is a pump which removes the water, but what was left in the pan is residual drainage.
That unit has a condensate pump built in, during the servicing, the hose was supposed to be disconnected and flushed, the line would have slime/slush buildup along it a back pressure would cause a error code for the pump, stop unit functioning and drip water from the unit.
After seeing that I would have to disconnect all the wiring to clean the unit, I doubt I will buy one of these. Mini manufacturers need to come up with easier to clean designs.
Mines are full of mold. This apartment never checked them.

Great video BUT!!! the drain pan should be removed and cleaned properly for indoor air quality.
Now imagine you work in a big building and you have like 300 of this 😂. Not feasible
Replacing pump
Pump motor : give of 2502 error!?
Hi Wilmar. All of our unit error codes include a combination of numbers and letters. Your unit is likely not from the USA product line. Please contact your local distributor for troubleshooting tips.

You didn't remove the styrofoam?? Really?
Nice sir good tuturial support me sir more video
You not claening water dry
This is really terrible engineering. Imagine that the control panel was no where near the fan and condenser. of imagine a proper filter that you could just replace every six months, like current all house ac units.
This is the disinfection of a clean device, a dirty device cannot be cleaned in this way.
Sar Hindi me boliy
Sorry Samiullah, we don't understand.
Not professional work
The technician in the video is an HVAC technician with a Masters degree in Engineering. He has thousands of mini split jobs under his belt. This is about as professional as it gets!
