Hi Aiyub
If you have a relationship with the particular company, ie. you buy a lot of kit from them, or you have a good freind who can get their hands on them, then perhaps they would give you the manuals.
If you don't, or if you're in direct competition with the suppliers service arm, then I can't see why anyone would expect to get given all the information for free. You wouldn't help a competitor for free would you?
Trane are actually one of the better ones for technical support, in my experience. Also, Airedale's website is really good, as are their tech. support guys. Never had to ask York, but I have contacts there who could probably help me out on the QT. As for Carrier, forget it! I hear from my contacts that they're actually
tightening up on what information they'll give out. As far as I know, Linde, Hussman and NRC (when they were still around) never even had a technical support desk!
I believe that most, if not all of the manufacturers have a policy of not giving out passcodes and the like on technical support, for obvious reasons.
Finally, most equipment ships with manuals, some admittedly better than others. If someone is stupid enough to lose them, or dishonest enough to take them when they get kicked off site, why should the supplier give them more manuals for free?
