Thank you for this video. My system was showing low superheat so I took out some refrigerant out and after that the unit's pressures (low & high side) started surging up & down. Guess I will have to recover whatever is in there, pressure test the system, pull a vacuum, then add some new refrigerant. I'm a new tech gathering all the service tools. Which recovery machine do you recommend?

The new field piece and navac ones are really nice . The one is most commonly see in the field is the Appion G5 Twin . If you’re going to invest one , make sure it uses a DC brushless motor as well as your vacuum pump . Reason for this is the new line of refrigerants coming next year to replace r410a are classified as flammable and the manufacturers only want brushless motors used so there is no chance for spark ignition ( even though a spark wouldn’t ignite them anyway , it’s a safety precaution )

I’m struggling with an rtwd chiller been working very well but now it’s tripping on low refrigerant temperature. Possibly low on charge what do you think when you see those alRms
@dfwhvac4 ай бұрын
Could be a few different things but immediate thought would be low on charge. Check all connections including threaded connections for sensors and transducers , king valves , etc with soap bubbles . Many leaks common from those areas on all Trane chillers. Pull all panels and inspect coils for oil stains . It’s possible could be a metering device problem but not likely - usually you’d get a low suction super heat alarm. After checking with bubbles , pull the water strainer and verify if it’s clean or dirty . Final step to actually know for sure if it’s low charge would be recover the charge and weigh the charge and compare to data tag. If for example your charge weight is 120 lbs and you only recover 70 lbs this for sure would be your tell tale sign. Hope this helps

Thanks for the video, how often should someone change the oil of the pump?
@tomniielander9445 ай бұрын
Most pump's recommend after every use, which I assume would be every couple of days worth of use. A used oil would not allow the pump to pull-down vacuum to full spec. So a pump that can do 25 microns, would top out at 100 or 200 microns with used oil. So you can close off all the vacuum ports, and just have a gauge attached, and see if you can get the spec to check oil condition. Basically the oil is hydroscopic, and absorbs moisture and other stuff that degrades it's performance. Also this Fieldpiece pump has two reservoirs, and allows an oil change without breaking vacuum.

Just a question when ubreplace the refrigerant R422 is there any other adjustment u havevto make?
@HHS-LLC3 ай бұрын
It's only that easy when you are using the setup you are using (MQ converting with p/t programmed in). If you are using simple manifold gauges, you need to convert pressure values to temperatures using the pressure temperature chart for R422b (Nu22b). It is not exactly the same like many think it is. www.freon.com/en/-/media/files/freon/freon-mo99-nu22b-retrofit-guidelines.pdf?rev=cb47ceae0ca247879c21e65941aa1546 pgs 13-17 Thanks for the video.

Yessir , recovery and charging should only been done with verified water flow on chilled water systems to prevent potential freezing issues in the tubes or heat exchanger

Can these be installed on a heat pump system? I like to use my air conditioning when it’s cold outside but my system is a heat pump so I still need the heat for the rest of the family when they’re home.

If that was a semi I’d say oil looks like 10+ years old/or dirty system/or running hot. Pre normal for a screw chiller tho considering compression ratios, you’ll get that darker tint on the POE pre quick from the elevated DLT

No point in overpaying for hand tools that will preform in a similar manner than a cheaper version and that are likely to get beat up from use anyway. Save your money for the high quality tools you actually need or power tools.

Do you guys charge the same when working one handed and making videos? I get that churches get a discount, we always gave one, and they are often sales tax exempt, but if we would have worked one handed on electrical systems we'd be in trouble. If there was an issue, even years down the road, an insurance company could/would hammer you.
