    Manufacturers F*#k ups



    One thing this trade is well know for is equipment that supplied with major faults that should never have reached the field. I will submit a couple that have given me grief, I'm sure we can build on this list

    3 Phase (415v) package unit fitted with single phase (240v)compressor

    Hermetic compressor with partially welded shell

    250kg Reviever with dip tube welded in upside down

    Evaporator coil full of epoxy coating

    No I'm sorry I disagree with you.

    We all know that the manufacturer can make no mistakes.
    That all equipment is designed and built to last 100 years
    and would do if it was not for the naughty engineer who goes
    and breaks said perfect system

    For example the case that was designed with the pipe tails coming out of
    the bottom of the case but with only 5 cm access under the case to install
    insulated 7/8" suction elbows.

    Or the cases that have the condensers along the back of the case with filters
    on that can only be accessed from the back and they are designed to stand
    against a wall??? or back to back with another case.

    Or the case that was sent out without any earth cable connected inside. It was
    not noticed untill a heater went down to earth, but there was no earth conection
    so the cleaner found the fault when she touched the faulty fridge and a good fridge
    at the same time

    Or the 150 Kw fan drive motor that was wired star delta, Not a problem you may think
    except inside the thing was wired for part wind.

    Foster had a big problem a few years ago with the factory putting ACC compressor's in all chillers and freezers

    What a HUGE mistake that was, spent most of the summer replacing comps.Well it was a good think for the company not soo good for foster.

    All sorted now though, there back to unite or danfoss

    Re: Manufacturers F*#k ups

    My favorite manufacturer screw ups are on machines entering from China, Korea and India.

    I'm not entirely sure how the things end up in the country, considering most of them use green wiring to carry current (a big no-no here in Aus, considering thats reserved for earth!). Since the plugtops are rarely connected to the earth pin anyway I guess it doesnt REALLY matter what colour wiring they use - you'd be dead regardless.

    One Indian unit I worked on broke pretty much every electrical rule in the book, and compounded it by having brackets in wet areas made from unpainted mild steel (not even painted or galvanized) which were already rusting by the time the thing was installed. The actual problem I went there for was no gas in the system... which turned out to be due to the sparrow-poop soldering job they'd done on the condensor which had more holes than a whole tournament of golf courses. By the time we quoted repairs to the condensor, replacing the rusting brackets, replacing the illegal wiring AND giving no warranty on anything except the EXACT work we did (documented) due to the poor quality components used elsewhere I think they ended up just buying a new unit.

    One Korean unit we got obviously knew that we needed 'an' earth connected, so they'd wired an earth wire (red, of course :\) into the terminal strip.... but then once the wire made it out of the electrical box they'd just chopped it off and cable the bare end into the other cables so you couldnt see it. Crazy stuff. The slightly disturbing thing is that 'someone' had test & tagged the unit with a generic test & tag sticker (with no company name etc on it), and put the test date and expiry... but left the license, name and other particulars blank. Clearly they didnt want to be associated with it, yet put a tag on it anyway???

    Re: Manufacturers F*#k ups

    Had a situation where a water chiller was fitted with TX valve installed backwards, inlet was the outlet, the outlet was the inlet, the Alco vav body had an arrow for direction flow on it. Chiller did not do much at all. One point they got right was the external equalizer was correct, really hard to screw that up. Manufacturer 'said impossible." for reverse install. My reaction was get in your car now and be on site plus bring order number for repair.

    Re: Manufacturers F*#k ups

    Had a server room where the close control units were installed with water copper piping plus threaded iron joints.
    Manufacturer (me) called in to recover refrigerant, remove the whole piping and start over.
    The installing company went out of business because of it.

    Re: Manufacturers F*#k ups

    Had a issue with an ammonia screw package the other day.
    Unit was supplied to one of our branches is Capetown by Grasso and was installed on a slurry Ice system onboard a fishing trawler. The unit had 28 hrs on when it showed up by us in Namibia. It would run for 20 minutes without a problem and then sudenly the oil temperature shot up and the unit cuts out on high lube temp. I removed and inspected the thermostatic valve on the oil cooler but could not find any problems with it. On closer inspection I found that the thermostatic valve was installed the wrong way around. So instead of feeding cold oil when the temp goes up it was giving hot oil straight from the seperator. Lucky for Grasso we have a branch up in Namibia which sorted out the problem for them very quickly.If they had to come up themselves it would have been a very cosltly exercise.

    Re: Manufacturers F*#k ups

    Well yeah. As a controls commissioning engineer I encounter all this. Often have to do last minute on site mods & the way the kit is constructed it isn't made at all easy! Factory pre-wiring is totally inappropriate for the way the equipment has been applied but nobody's told the control panel builder & he hasn't bothered his arse to ask; mods are difficult because everything is inaccessible & stupid push-in terminals only work once.

    Merry Christmas everybody!
