I have seen those transducers leak. Curious on folks thoughts on the best leak detection device?
Is it still the Johnson Control A/C plug in model?
Thank you.
The filter dryer can had no medium/ core.
Still On this Vogt P18. I went to replace the filter dryers and found an empty can on the suction side. After replacing the suction and liquid line dryers the compressor is with the lack of loud...
It is a real snafu.
"Does it still look like this?' Indeed it does. It is on a ten foot high platform for gravity feed into its bin.
Texas Pete , I appreciate this detailed response. I did change the oil. Next time I will remember to close off the compressor to prevent the problems you point to. Of course my intention was to pull...
Happy to help out a friend where I can.....
If one gets out of bed and goes beyond tying their shoes, mistakes are par for the course. Its those that never move that have the clearest record.....
This has been a lively discussion. I appreciate all of the input even from those who never make mistakes. Cheers.
Great help! I am not sure there is air in the circuit.... I tend to agree that enough gas was exiting to prevent much air infiltration. Good tips, I will try. I appreciate it. Mahalo.
Yes I botched it. I would recover and start with a new charge right off if this were a five ton unit with a few lbs of gas. But as you have pointed out there is 200lbs. My hope is the was enough gas...
The head is a tad high. The oil pressure was low. There were some loose connections on the load side of the compressor contactor likely burning the windings. The oil screen was plugged causing low...
"Well, if you're going to screw up do it on a good machine!" Right. Thanks for the encouragement...
Yes it is a water cooled barrel at the top.
I appreciate all the replies and beginning a new thread. The machine is a Vogt tube ice maker model P118F. After cleaning the oil pump screen I failed to pump it down prior to restart. It has over...
How can I remove air from a refrigerant circuit?
I have been called out after a lightning strike and found two sections of CSST with a total of nine holes. The home owner was cool headed and heard the gas leaking after the strike and went outside...
soaker,
Thank you for the feedback information. You are correct we spend way too much on tools and equipment to buy short lived stuff. I will get some resolve and post again.
I have had no good luck with any of the rechargeable and was told with good advise to get the Johnson controls AC only models RDL-H10G-1.I sent my Fieldpeice back for calibration after it detects...
Good luck with the work. If you know HVAC then apt maintenance should not be an issue. Some electrical and plumbing would be about as tough as it might get.
But seeing how you would not be competing...
