Having watched quite a few of your videos, I find myself being impressed by many of the installations of the rooftop equipment on many of the restaurants you've serviced and how lucky you are to get to work in such a service-friendly environment. For example, on this roof you had a water supply. In my neck of the woods, I rarely have a water supply on the roof. I'll remember that the next time I'm running 200' of water hose! As always, thanks for all the great videos you put out, Chris. You're the man!

@juanffmunoz80 3 года назад

Hey Chris, one time I accidentally made a leak on the condenser with a self tapping screw, I had a choice of telling the customer that it was leaking already, but no I said I was washing the coils and accidentally made a leak when putting it back, so I didn’t charge any extra, I have that costumers for 10 yrs and happy, integrity always wins!

OMG, I work in industrial automation and the number of times the date being wrong has sent me on a wild goose chase is maddening.

@movax20h 3 года назад

A lot of stuff is networked these days, and can get a date and time from a network using NTP. In older dates some equipment in some countries used radio broadcast of time to synchronize, i.e. in Europe, DCF77 is used for like 30 years in many devices. GPS would be the best, but a lot of this equipment is mounted indoors, so it wouldn't work. But still it sometimes can be incorrect. But yes, I have seen countless numbers of cases of time being wrong, because it was not set, or there was no battery backup for clock, and power outage for too long or something, or simply never set in the first place. However, there is a rather easy fix for the issue. In the log / alarm history, show "x hours ago", "x minutes ago", together with a date and time. Easy.\ I do design IoT devices, with a lot of emphasis on monitoring, logging, and timestamping things, and making 100% sure the time is correct from the start is really important and a big challenge, but it can be done, but it is a bit complex.

It is made out of black Bakelite, and you light a dish of alcohol above the pressure tank on fire, this heats the other alcohol in the pressure tank, and causes the torch to fire.

I remember in 2019 when you said that microchannel when you don't blow the water out before startup it causes high head nuisance lockouts. It stuck in my head for some reason. Went to a job where this was the issue. Someone cleaned the condensers on a liebhert unit before I got there & the people cleaning the coil didn't realize that the remaining water is why they were locking out on high head. I explained to everyone several times what had happened, but no one really believed me. I knew this was the case though & once I blew out the coil, the unit was working like a charm. This was over a month ago.

Water sits in micro channel coils, idk how that would cause high head. Can u explain?

@christopherbertolino2453 4 года назад

Never heard about or encountered this as I wash coils every season all shapes and sizes but my theory is the water gets trapped between the fins reducing airflow over the coil causing high head I always assumed it would help initially and just get sucked thru and dry up. I learn something everyday in this trade

I take a similar approach. If I missed something, and a callback occurs; I credit off the trip charge and/or the service omitted, if it should have been included in the prior paid service. Sometimes things are borderline. When it is, I err to the client's benefit. Often the client does not really care as much as I do; but I like to sleep well, knowing my work is right.

@Dan-ger82 4 года назад

You're a good boss to understand mistakes happen. I used to work restaurant refrigeration for years and have had a number of mistakes over the years. I hooked up water valve on Hoshizaki ice machine without powering off the breaker and just the on/off switch and shorted out internal transformer. My other tech once pumped down semi hermetic compressor by holding in 1 contactor and not via low pressure switch and didnt realize it was part winding start and burnt up compressor. Mistakes happen. No ones perfect.

Regarding that exhaust fan spraying grease droplets that foul the condenser of the AC unit, one solution might be to install a deflector plate on the direct path of the plume. The airborne droplets would impact the plate and condense there, rather than migrating over to the condenser coils' fins.

@rodgraff1782 4 года назад

I can’t believe Trane is still using the voyager name. I remember when the Voyager line first came out in the 80’s with the Microprocessor control and solid state sensor or thermostat. Back then, it was way ahead of its time. One thing I didn’t like about those early units was the access panel for the economizer controls and motor. It was on the rain hood, and water would leak in and destroy the electronic economizer module. Corrosion on the economizer module terminals was always a problem, and those plastic motors and modules were expensive, even back then The blowers were good on the larger units. I liked the idler pulley, heavy brackets, and the way they designed the belt tension adjustment. I never really experienced a lot of trouble with those early units, except for one ten ton, where the factory had cross piped the liquid lines for circuit one and two. Everything worked when both compressors were on, but when it was in first stage, the readings went crazy.

@alanparadise3139 4 года назад

One thing to alleviate these problems is yearly cleaning maintenance once or Twice a year. But most don't want to spend the maintenance fee which would be cheaper then to wait to fix a problem or a major service call. They think it will run without issues for the life of theses units. DOING MAINTENANCE WILL SOLVE most service calls.

Open closed had to get it in my head not to think open is good closed is bad. An open store, open arms, open heart, open mind are all good etc. I work with a lot with micros switches, and have confirm with my “other brain”that I understand the circuit. That I’m not assuming. Either could be what the designed intention is of the guy who built it. Glad I’m not the only one. 🤪

@jth1699 4 года назад

Safety circuits are built in two ways - either normally open or normally closed ... the normally closed system is self monitoring - as in if a wire gets open or grounded the system will shut down. Some safety systems change states when power is applied to them - so the print will throw you a curve when they draw the components in the shelf state with the power off then when you turn the control power on the components changes state and then has to change state again to show a fault... you see that in speed sensing circuits.. so the upshot is to realize the relationship between "normal" and "tripped" might not be "open" or "closed". In this video you unconsciously sorted out that same issue by setting the float switch and comparing the readout on the interface with the condition the switch until you understood what kind of condition the interface was reporting... natural born troubleshooting skills guy... my favorite troubleshooting saying that covers every situation is "if this then that" - just compare the conditions with the results and if there is a conflict then there is a problem.... you do good instructional videos guy ...

I have got to the deep part of the interenet and i love it

@HennerZeller 3 года назад

So looking at the digital control, it looks kinda neat, but there are things that clearly show that the manufacturers are still in their early stages of implementing these. I think for any kind of switches, the interface should say something like 'triggered' and 'normal operation' or something so that it is clear what to look out for. Because switches can be normally open or normally closed, so a simple 'open' does not tell what the state is. That is what can add to the confusion (that you experienced here). Maybe they should contain all the relevant information such as 'triggered (electrically open)' to indicate what the status of the system is but also indicate what to look out for when multimetering the switch ? There is enough space on the screen. Since they use an LCD, they could also indicate the results that need attention with a little icon or background pattern (or color, but that might be harder to distinguish in sunlight). Also, what if any digital control unit would just show the current time and date at the top of the screen somewhere so that you don't have to manually go to settings ? Personally, when I write software that emits logs I also like to include some quick digestable information like how long ago that was; still the full timestamp, but something like 2020-07-01 12:33 (26 min ago). Also, touchscreen is fancy and stuff, but actual physical buttons on the side of the screen would be much more service-friendly (like the kinds they have at ATMs). Makes it easier to operate with gloves. Hopefully writing feedbacks to manufacturers about the servicability of their devices (or at conferences?) slowly will change them to be really good.

It sounds to me that the fin spacing on the micro-channel condensers is too close for the surface tension of water, and even with the surfactant effect of the detergent, capillary action is retaining the water. Until you can overcome that - like with the leaf blower - your normal low draft from the propeller fans is going to struggle to get adequate airflow across the coils. In other words, blow out the trapped water from the fins before you hit the start switch! ;^)

Good tips as always!

You said that the first tech to service this unit for this problem was investigating a VFD error but couldn't find anything. That got me thinking. I'm no HVACR tech, but I do know a bit about electric motors and VFD's, so here's what I was thinking: Do you think that those units with a VFD on the blower might be able to detect a broken and/or slipping belt? My thinking is that if the VFD can already detect a locked blower by the motor running amps being too high, then it would be able to detect a slipping/broken belt by the motor running amps being too low, right? Are there any units out there that are sophisticated enough to do that? My thinking is that the VFD already has enough electronics in it to measure the needed parameters, it just lacks the instructions to tell it what to do.

@dothemathright 1111 True air density changes, and therefore I guess the load on the motor would change too, but if the VFD is seeing 3 amps draw when it usually draws 10, chances are high that the belt broke.
