good ya caught it
just in case it wasnt mentioned
better check nozzle orifice size, r-22 is smaller than 404 and 507
whats the pay?
ouch
if you doubled that, that might help with cost of living there
you stated you need "top gun"
yet post wage range from apprentice to not so much "top gun"
you are not in a unique position, having to find 'top gun' mechanics.......
where i am at, large...
yea, my local said they have had some with travel cards go there with little to no issue
might just look into that
you have a link to the company in question?
what do mean by hotter?
oh I thought you knew it was wrong, and when you installed the new one, you corrected and tested it.
sorry
I think you need to stick to just the facts you have in front of you, and convey to copeland, I am sure there will be no issue in warranty
-you found what could easily be the cause of the...
forgot to washer down the liners,,,,,,,,,sounds minty fun!!
I was called to do start up on a new 5H80, I get there, and see 3 dead ones hidden in the corner of the room!!!
I asked whats up...
I kinka figured it was real low.
And I totally agree, one is not doing their job fully if they dont fill out a start up log, I have done my best trying to instill this step to apprentices that...
copeland offers a 2 year warranty if you fill out their startup sheets
you have to ask for them
if you get nowhere with this guy, phone corporate
unless they have done a 180 recently, that i...
copeland's policy is
1 free replacement regardless of the screwup
It is to my, and bitzer rep i deal with, great displeasure they do that, but that is a fact.
BItzer now does the same

and must have never ran out of oil
until it did.
if both control wires were connected to L
you removed the SAFETY
L and M is the switch that OPENS and de energizes the contactor.
now you know why the compressor had no oil in it and...
Inspect the contactor contacts.
do they still look new?
then you have to use your own judgment
if it has no UL markings, who knows
its an appliance
is there a UL marking on the data plate?
thank you
what is top hourly rate you are willing to pay?
sized bigger.
that is copeland recom
UL, the governing body say 1.56 is acceptable
i had this talk, many years ago with bitzer and copeland engineers as i said before
UL relaxed its standards, and also...
copy and paste from bitzer

Also if i remember
contactor is 1.56
conductor is 1.4
I talked with both engineers at emerson and bitzer on this
they both mean the same thing, they told me, just different convention for authorities they serve, europe or North america
as long as...
I suggest you get the MOC by contacting the manuf via internet
this is how you size your relay/contactor/motor starter or even VFD
there is NO OTHER WAY, this is the industry standard by the compressor manuf to meet UL requirements
you go to the manuf...
the fan will be fine
used them on many applications, just find the right capacitor is the thing
fan motor cycling is far worse than variable speed for the motor, IMHO
its an option, whom ever bought it, opted out
and chose fancycling instead
you should have chose a P66. variable speed controller instead IMHO
"I didn't grab the suction temp at the comp but felt like only about 65*F, not very cool."
you have a -20SST at evap with 8F superheat, and the pipe temp at compressor is near 65?
are you sure...
how many defrosts has the unit gone through?
you have 19 TD, sounds like the coil is frozen over
dont limit yourself
expand your imagination!!

1 Tech from cimco
and
2 facility untrained persons
none were wearing their Respirator
What about US "R" people???
Merry Christmas !
okay
how many hours did you spend in total on this repair?
How many billable hours in total for this repair?
i think that is operating signal
design pressures, i like burst, are way higher
I have not heard that anywhere, talking with engineers at emerson or alike............
here is a little spec sheet
