I have been ill for over 3 weeks so haven't been able to start this but today I have started
.
I first dismounted all the surrounding plasterwork and was able to see now that it was not a custom job as they told me (or remember 12 years ago)
but that the evaporator is a standard Searle TG2-7.
I opened up the metal cover that keeps on hanging on its hinges since all the airco tubing goes through it in the back (can not remove totally),
but I had enough room to disconnect and remove the motor with fanblades
I removed the fanblades and was able to see that it is a one phase 240VAC motor,
the manufacturer and type of the motor:
A.O. Smith
Ser 4NA UC16085
F Model type AB2N6259K
240VAC 0,46A. see picture.
Unfortunately as you can see the top (and back) plates are fixed with rivets not with screws. So I have as a question, whats next?
How can I lubricate the bearings just put some oil or WD40 in it ? Or can I only replace it with a new one
Another question: how can I make this motor run a bit more silent during the night, can I use a Variac to put 180VAC-200VAC on it during the night and switch with a relais
to 230VAC if the cooling starts? Or is it damaging for the motor to run on a lower voltage? Or any other circuits to do this?
Thanks all
