a Nice Little Winter job on that unit When your not so busy is Clean up ALL THAT wiring. Open up All Lower boxes and check for chafed nuts etc. inspect all electrical wiring. a Quick vis. in ALL Connection boxes.
Beautifully described how a ZP powerhead works, wondering if that was the wrong valve for that system, your approach to service is second to none my friend !!!
thanks Chris the valve is not wrong for the system it will work ok but it will have a long pull down time if the system is very hot due to that ZP powerhead
yes I will, I will be going live on UA-cam this evening 7/8/19 @ 5:PM pacific time come check it out if you can ua-cam.com/video/11n-kqTVvD8/v-deo.html
After watching your videos I went out to my local pawnshop and bought my first Fieldpiece multimeter and I’m very pleased with how it performs, the ease of use, and build quality. It works better than my Extech multimeter.
Thank you for the upload Chris. Definitely buying the coil wand when I return back to work. Been out of commission recovering from ACL reconstruction surgery. Getting alot of ideas watching your content.

Good vid. i Guess the Moral of the story is don't set Your R-404 Freezer Low pressure controls above 25psig.

Most pressure controls I set at 15 cut in, 0 cut out on pump down systems. The scrolls will sometimes jump up a few PSI. Occasionally I will do cut in as high as 20 if the particular unit has short cycling. One short cycle is okay after a pump down, but any more than that, I adjust a little. In the winter here, pressure controls set too high show themselves pretty quick. Headmasters and heated receiver tanks are pretty common here. Fan cycling on the older systems mostly, and sometimes on new ones.
I'm no stranger to restaurant equipment. We've had to make sheet metal stuff for many of them but ya know it sure amazes me how many times I've seen them where they leave the door open and it doesnt operate like it should because they leave the door open anyhow.
Absolutely hate those MOP valves. In my opinion they only used when the system isnt sized correctly, or when the system is being used outside its design intent. Would have been better if it was variable speed driven with extra capacity in the condenser for those "hot pull down" times. Liked the video, and i totally agree with cleaning the area around the condenser, my boss always thought i was playing with water he never saw the logic behind it.
Hey bro, great diagnostic work and preventive cleaning thoughts. Just noticed at 3:57 the flexible RWA(?) steel conduit coming into bottom of High/Low control doesn't have romex nut on it. The two pink control wires run through it to yellow terminals. Only point it out because of vibration.

Btw , you guys have such awesome tools , man , I've never seen that coil cleaning tool or that awesome flexible shower head over here . Plus , the geniuses over here often don't install a tap on the roof , so you don't even get to use a hose😤
Now , what makes me scratch my head is: let's say you did need that pressure limiting power head , how could you find a compromise to keep it and yet set the low pressure control so that the compressor doesn't short cycle with the bypass ? That would really do me head in ... great to see how thorough you were and that you made sure you came back after the late night call 👍
I'm in Australia and every freezer we work on or install will have a cpr valve or mop txv. Thats due to the 4 to 6 defrosts a day that will cause suction pressure to be higher than what the compressor is rated for. Mop valves are typically sat at 50psi and i set my cprs at 40psi s a general rule of thumb.
A few problems I see 1.Those drain channels are very dirty 2.crankcase pressure regulator valve needs to be lower than 30 3.Pressure rises with the evap fans running I'm sure there's more problems but those are some I see Also I'm in HVAC School so still learning
Question. Wouldnt the pressure rise with the evap fans running? I've worked on display cases that use the pressure switch as a temp control. Cuts the compressor off at a set low pressure then as the box temp increases the pressure increases and cuts the compressor back in.
the pressure control is not the temperature controller in this situation, there is a thermostat and solenoid valve down at the coil. The problem here was when the thermostat would call and the solenoid valve would open the pressures would not rise about 30 psig to close the low pressure control and this was because of the pressure limiting power head on the tev so I adjusted the pressure control lower until I could replace the powerhead.
Ah the southwest. I miss the days of having a water spigot on the roof.. Or even outside the building for that matter. Lol. Now in the northeast? Nowhere to be found.

Never even heard of a pressure limiting valve. Did you know it had that beforehand or did you find that info posted somewhere? Otherwise you would have to call the factory and hope they still had the specs.
Once I saw the pressure issue I looked at the code stamped on the valve power head and it said KT-43 RZP which is a low temp 404/502 pressure limiting powerhead
I just got into commercial after 7 years in residential, and I love it. Have you ever messed something up doing coil cleanings with all that electrical underneath?
I worked with a guy who called me middle of night shorted tlhe low oil comp switch to 230" opened the switch on a 100ton unit we jumped it for the night

I'm pretty sure you're not allowed to have wires going through separate holes as the fields can create eddy currents in the metal of the cabinet. Bad form by the other company if so
I hate those knock off ColdZone Racks! Those condenser coils get so gross and rot out. Then you get water in the dual pressure control if you don't protect them.

MOP valves are absolute crap. I design this stuff, its much better to use a CPR valve OR a simple pressure switch inline with the llsv to turn it off at 50-60 psig.
It pisses me off that a so called professional leaves wires hanging out of a box and and ran those two wires through non protected holes when a hole and grommet was right there. The guy who did that should be ashamed. Thats just lazy. Do you want someone coming behind you and seeing that? Or do such a good job that you would inspire the tech after you to do a good job also? Just my opinion....
It's interesting that it takes more effort and time to drill ragged holes than use that nearby gromet. I can only guess at the mental processes that lead to this behaviour. Having said that I remember a builder doing some work for me many years ago and whatever I asked him to do he would always do it differently from my requested way. In the end I found it best to say nothing and he then did it the logical and best way (as I would have wanted). Crazy.
I don't mind balance port, but am not a fan of the pressure limiting at all , I will be going live on UA-cam this evening 7/8/19 @ 5:PM pacific time come check it out if you can ua-cam.com/video/11n-kqTVvD8/v-deo.html
I see. I actually meant I was surprised you kept it on & got it that dirty. I thought it was gunmetal pewter or something like that. I’m from a family where wedding rings come off before bed or anything dirty or wet, for safekeeping.
Quick question for anybody’s: On a Lennox Energence unit(2 stage 4 compressors), the coils were extremely dirty and it went off on high pressure. Why would 2 and 3 go off (contactor not pulled in) but 1 and 4 stay on (contactor pulled in)? That would be half of each stage running so it leads me to believe that each side of the coil being dirty had something to do with it(front side and back side). I’m just a facilities manager and trying to learn more about these units. Let me know your thoughts from anybody.
On the Lennox Energence units the condenser is divided into 4 sections so it is possible for only two to trip on high pressure. This could be caused by bad fan motors and or dirty condensers
HVACR VIDEOS makes a lot of sense. I appreciate the quick response. After we cleaned coils and got the rest of the unit running, we were putting out 50 degree discharge air temp which is pretty good for where we are at.
Thanks for the videos.... I notice you don’t work on residential and your company might be a grate company to work for do to the time in location you spend takin are of the customers...

Not to mention the closed loop of metal between the wires acting as a transformer and heating up.

I'm in Australia and every freezer we work on or install will have a cpr valve or mop txv. Thats due to the 4 to 6 defrosts a day that will cause suction pressure to be higher than what the compressor is rated for. Mop valves are typically sat at 50psi and i set my cprs at 40psi s a general rule of thumb.
Up here in Minnesota need to get the pressure way down there for the low ambiant temps

MOP valves are absolute crap. I design this stuff, its much better to use a CPR valve OR a simple pressure switch inline with the llsv to turn it off at 50-60 psig.
It pisses me off that a so called professional leaves wires hanging out of a box and and ran those two wires through non protected holes when a hole and grommet was right there. The guy who did that should be ashamed. Thats just lazy. Do you want someone coming behind you and seeing that? Or do such a good job that you would inspire the tech after you to do a good job also? Just my opinion....
It's interesting that it takes more effort and time to drill ragged holes than use that nearby gromet. I can only guess at the mental processes that lead to this behaviour.
Having said that I remember a builder doing some work for me many years ago and whatever I asked him to do he would always do it differently from my requested way. In the end I found it best to say nothing and he then did it the logical and best way (as I would have wanted). Crazy.
I don't like pressure limiting or balanced port valves
I don't mind balance port, but am not a fan of the pressure limiting at all , I will be going live on UA-cam this evening 7/8/19 @ 5:PM pacific time come check it out if you can ua-cam.com/video/11n-kqTVvD8/v-deo.html
I'm surprised you leave your wedding ring on for some of this.
It's a silicone ring so it will not conduct electricity and or it will break away if it gets caught on something.
I see. I actually meant I was surprised you kept it on & got it that dirty. I thought it was gunmetal pewter or something like that. I’m from a family where wedding rings come off before bed or anything dirty or wet, for safekeeping.
I hate horizontal coils like that. No matter how careful I am when I'm done I look like a horrible cosplay of the swamp thing
Quick question for anybody’s:
On a Lennox Energence unit(2 stage 4 compressors), the coils were extremely dirty and it went off on high pressure. Why would 2 and 3 go off (contactor not pulled in) but 1 and 4 stay on (contactor pulled in)? That would be half of each stage running so it leads me to believe that each side of the coil being dirty had something to do with it(front side and back side).
I’m just a facilities manager and trying to learn more about these units.
Let me know your thoughts from anybody.
On the Lennox Energence units the condenser is divided into 4 sections so it is possible for only two to trip on high pressure. This could be caused by bad fan motors and or dirty condensers
HVACR VIDEOS makes a lot of sense. I appreciate the quick response.
After we cleaned coils and got the rest of the unit running, we were putting out 50 degree discharge air temp which is pretty good for where we are at.
Thanks for the videos.... I notice you don’t work on residential and your company might be a grate company to work for do to the time in location you spend takin are of the customers...

who ever wire these units, did a very sloppy job, where are the junction boxes ? open and exposed conductors with wire nuts, etc

kinda looks like you’re in the IE
Yep
HVACR VIDEOS born and raised there, nice
Good work what Freon used at what running psig
Holy Dirty Pan Batman. Those drain channels have NEVER been cleaned..
