york yt air removal

[t2]

is the only way to remove the air on a r123 yt to use a portable purge ? By warming the evap from hot water heater in mech rm the leaks I have found a,oil around comp equalizer line solenoid and 3 way purge solenoid. Suction elbow shaft seal and rupture disk were changed a year ago. Customer doesnot wantto pay york to overhaul machine which it probably needs since it sat for 2 years not running with only 200 pounds of r123. Machine is full off air. Since the purge only runs when comp runs I dont thing it will get this air out. Customer just wants machine running, they refuse to have gas pulled and pressure test. They want my boss to buy a portable purge. This customer really sucks.I was told another tech had fixed leaks and added 400 lbs a year or so ago but machine has just sat airbound since when maint guys runns it it goes of on evap pressure transducer. Customer just wants bandaids. They want me to purge air into a recovery cylinder ? This machine I thinks needs more work then I know how to do, have a boss and customer just wanting a bandaid, dont have a portable purge, machine sat for 2 years due to customer being cheap and not paying york to repair it. What the F.

??? Do you have a low pressure recovery machine? There is a way if you do!

[t2]

there is a low pressure recovery machine on site with vac pump built in

No, you could run it at minimum load and allow purge to take care of it, would need to be watched carefully though, negative pressure can be a real pain, if every manufacturer of negative pressure machines said there machines were tight there'd be no need for purge units.

I have heard of people blowing off air via valves from condenser, however this practice is an absolute no.no, you got a leaker call in someone to resolve.

this isn't a window air conditioner. if you are not sure how to go about repairing it and the customer doesn't want to pay to repair it properly....RUN! i can all-but-guarantee you that once it is 'fixed' you will have other issues and this customer will blame it on you. the customer is NOT always right, if they were, they could fix it themselves. sometimes, you need to fire customers...do it nicely....but recommend that they have someone else repair it and let them have the nightmare.

This machine I thinks needs more work then I know how to do,........

I believe that's probably a wise thought, and one that you should act upon.

t2,
after reading this post and your other one, I wonder what your boss and your customer are doing to protect you from the 123 hazards. There is only one way to fix this machine and if your boss and your customer dont like it, then F them-You are the frontliner who needs to go home to your family safely at the end of the day.

Are the 123 hazards any different from any other refrigerant hazards?

BTW if the customer is cheap and doesn't want to invest in his HVAC system, then like said eailier , piss on him. Don't do the work ,damn sure dont do it for free, things cost , either they want it fixed or they don't,
And u better believe, once u touch it , IT'S YOURS!!

r 123 is nasty stuff dont play with it it can cause some issues

[jayguy]

R123 is not any more dangerous to human health than any other refrigerant...yeah i read the reports....3rd nut and all in rats...read the WHOLE report. the rats were subjected to 32,000 ppm for 4 hours per day. the recommendation is less than 30 ppm for 8 hours per day. the rats that lived developed a bunch of crap at the end of their life yet they lived longer...just like people who live longer...they tend to develop more health problems too.

the same thing happened to rats that were exposed to R134a at 50,000 ppm...tumors, lived longer, etc.

and R11 was tested to the same effects at 26,200 ppm yet nobody complains about it.

what is more likely to happen? over-exposure to a low pressure refrigerant or a high pressure refrigerant?

done.

Agreed! If "something" happens to cause a leak on a low pressure machine while I'm there, I will attempt to stop and repair the leak, without even shutting it down. And probably won't even lose enough of the charge to measure. If "something" happens to cause a leak on a high pressure machine, I'm running away as fast as these ol' legs can carry me! And then, if possible, shut it down remotely. And wait for total loss of charge to dissipate. And "experts" say high pressure is safer for me and the environment?

Like the new name! And I no longer have to wonder what it means.
