Typically when there’s new equipment installed and there’s a problem right away, always in the back of my mind it’s something simple. Such as a loose connection or just not start it up properly and something was skipped. I had a service call later on one night on a brand new water source heat pump that was mounted above a security station that was tripping the high pressure switch. The only difference was the old unit ran off of R-22 And the new unit ran off 410A. Some people might wonder what would that have to do with anything but the 410a pressures skyrocketed. There was no drop ceiling below the unit and the ductwork sent all the hot air drifting back up into the return which was right there next to the unit causing suction pressure to go way up and head pressure to climb way up. To fix the problem I just had to make a few changes to the ductwork and units been running great since. I wish I could have shot a video but I did not have a good way to record with memory back then. Thank you very much for the compliment have a great day.
Years ago it used to almost instantly kill some scrolls. Some equipment such as Trane has a built-in phase monitor that will come up with a red light fault indicator and this will tell you to reverse rotation basically. I’ve had a few freq drives correct for the rotation on their own. Thank you for the compliment. I do apologize not posting on TH-cam for quite some time life‘s been very hectic and working a lot of overtime.

@@krig1993 the power entering from the breaker panel to the disconnect are the Main wires. From the disconnect into the unit are the main power feeds as well. On this particular system being 3 phase. You can change the rotation of all the motors by changing. Either 2 of the 3 wires in the disconnect or in the unit at the terminal block. Sometimes motors are installed incorrectly, and they are running backwards.
Now, some of these small RTU have a small VFD for the blower , I in fact just replaced 19 units on a Best Buy here in Chicago and they were all lennox with the VFD. The VFD straightens out the rotation in programming so looking just at the rotation on the blower is incorrect, you must check phasing at the compressor the blower goes in the right direction no matter how its phased.
Thank you very much for that correction earlier after watching the video I was like wait a minute this is larger than 4 ton it’s nearly double that when I looked at the nomenclature and figured it out. Lmao. I had a unit that the blower motor was wired incorrectly voltage wise and the freq Drive allowed it to run. it sounded horrible but it actually ran.

You can usually tell when they’re running backwards just by the way it sounds and simply by putting your hands on the copper and feeling it. Also…can’t leave that panel off while it’s running bro! You know this!
Totally agree night and day difference. The noise is a good indicator along with temperature on the copper, but you will notice an immediate issue on your gauges, pumping or not pumping.

@@Matrix13533 yeah it’s amazing the stuff we run into and neglect the equipment goes through not to mention improper installations/start ups. Some people ask me what’s the best equipment.

Can you explain the static pressure on RTU units. I have one that data tag says Static pressure 1.6 but what I get is total static -85 on my manometer..
You went down on overload is because you ran the system too long with the panel off and all the air bypassed the coil. Air takes path of least resistance
If the compressors were in the correct rotation it would’ve tripped on high head pressure. “With the door off” Since they were running backwards they weren’t pumping refrigerant and had no SuperHeat to cool them. The panel being on may have helped a little too cool them. “ a little”. Thanks for the comment Nathan. Always thinking. 👍
@@moonlightacmaintenance3232 Yes the thermal overload is Built internal on the compressor. High pressure, low pressure, Freeze stats are just a few of safeties that are external but yes this tripped on internal overload since the compressor was running reverse it could not get proper SuperHeat to cool the motor therefore overheating.

Hello good afternoon Waylon. Thank you for the thumbs up always appreciate the encouragement I’m editing a video shortly here and will be throwing it up hopefully within 30 minutes. Hope your weekend is going well I hope you’re ready for The Holidays. Have a good day.
Great video on how mistakes can be made at startup. I am a big fan of a checklist anytime a new piece of equipment is commissioned and I would think phase would be number one on the list. If the manufacturers would install phase monitoring relays like Eaton's D65 Series PMR it would eliminate problems like this and phase loss at anytime ( does it really add that much cost to a $10000 or $20000 RTU ?). I will take a little exception with you, at the start of the video you said it looked like a good install ( my exception would be the sediment trap installed at the wrong orientation. The ones with the missing doors at least had their sediment traps installed correctly). Keep up the great video content👍 Regards from St Louis🦲
Thank you very much bob I appreciate the compliments and suggestions. Some equipment is already factory installed with these monitors and pretty much eliminates accidental screw ups. Trane On their packaged rooftop units typically have a phase monitor With a green / red light depending upon if it’s good or incorrect power phase. Typically when I rebuild a compressor I will use cardboard cutouts and draw up a small blueprint of that motor to put bolts, gaskets and other material in certain positions not to mention take photos. I wasn’t a real fan of that trap but my biggest concern was to protect the compressors. To make sure it is running how it should. I was only showing a demonstration taking a risk on damaging the compressors yes but to show people what it looks like if you run one in reverse. Also it was running for quite some time before that so what’s a few more minutes. Lol. I often wonder how much that extra cost would be on an expensive piece of equipment by throwing an extra safety into the system or an optional upgrade? That would be something to ask the manufacture.

Believe it or not that was in the correct rotation. Typically when one motor is in the wrong rotation for the rest of them will be in the wrong rotation.
