I would understand manufacturer training to limit thier liability, but why now with 410? What about all the warranty issues with 22? How do they expect seasoned techniciains that will not change their practices?Originally posted by trane
I think some of the manufactures are requiring that you have factory approved training before they will sell to you. I know that the local York distr. requires you attend there training first. I would say that it is to limit liability and warranty problems from incorrect installations.
I know guys that don't care about performing the correct procedures and all they know is that the pressures are going to be a little bit higher and that the oil that is used in 410a systems is acidic... Yes, they say that it is acidic. I know that it is hydroscopic, but not acidic.
