Re: Hall of shame.
I can't work out four things.Why the gauges was freezing up.How you can reclaim gas into a Refrigerant bottle of R22,past the built in none return valve.why your tutor was using R22 after Dec 09.unless it was a recovered R22 from site.the only cost is for disposal of the now mixed refrigerant at about £10/Kg + cost of wasted R401A .The R22 should be returned anyway by now.

Re: Hall of shame.
Regards the hall of shame during the seventies whilst working as an apprentice in Glasgow one of our journeymen mysteriously disappeared after attending to a breakdown at the police mortuary,it turns out he was in hospital suffering head injuries,the reason for the injury was at the mortuary he decided to play a joke on the appie and sent him for a 12 inch shifter meantime getting under a shroud, when the appie returned he rose up under the shroud to give him a fright, needless to say he received a whack from the shifter and had to be taken to hospital. A good case to wear a hard hat.

Re: Hall of shame.
I was a refrigeration and a/c engineer in a health care facility a few years back. It is my job back then to supervise installations of a/c and refrigeration equipment, one day I assigned 2 greenhorns to install a 2horse power window type a/c, the work went along well that day. the following day my supervisor had asked why didn't I installed the a/c, so I asked the two people who I asked to Install the a/c and they told that they had it installed and they to are baffled of mysterious disappearance of the said unit. so in parallel of the ongoing investigation I gave an order to install a new one, by the next day the unit that was previously installed had disappear again. so I went outside and look for the unit and noticed that instead of the usual expansion shield for bracket mounting they used wooden plug and nails and there is deep and murky fish pond directly below the opening for the window type.
guess what is in the fish pond, the second unit sticking out of the water.
case was closed and as for the two I had them cleaning duty of the window type a/c for a year.

Re: Hall of shame.
Years ago, while working for the 'leading' refrig company in NZ, I attended a call to a truck unit which had been recently worked on by our third year apprentice. The reefer was tripping out on HP. Airflow was fine, but subcooling was unusually high. I reclaimed the refrigerant - and then charged the unit with 4 of the 10kg I removed from the system...

Re: Hall of shame.
Got a call to a small spit that a subby put in but didn't seem to work. Head pressure was almost 60 bar on r410. He pressure tested to 42 bar with nitrogen. When it held over night he just opened the valves and ran it. Amazed it was still on the wall. Recovered vaced and recharged and amzingly it's worked perfect ever since. Needles to say he does no work for us now.

Re: Hall of shame.
Only 2 to add from me :-
i) Asked to follow up another 'engineer' who had faulted a compressor on a chiller but had included no details. Last time I looked it was unusual to find a compressor on an absorber !
ii) Asked to follow up 3 different 'engineers' investigating un-satisfactory performance from a VRV. Much better operation with the service valves open !
I fear this is just a sad reflection on the state of our industry !

Re: Hall of shame.
Today I was surveying a local school. I noticed that some work had gone ahead that I had previously bid for.
I didn't get the job......... I was too expensive
Perhaps you get what you pay for ??
The local electrician didn't have a level, or any idea how to support a condenser in a school playground above children's heads. Check out the wood screws.
Oh.....and I warned them not to confuse MHI with MEUK.

I hope you brought it to the Head Teachers attention as it could kill a child or teacher for that matter.

Re: Hall of shame.
Old cold room, originally R22, converted to R422D. Copeland scroll, with oil separator. Automatic oil return valve faulty (constantly open), some bright spark decided to fit manual valve in oil return line and (of course) valve was constantly open. It killed 2 compressors in meantime, but they still couldn't figure out, why
