Recommend me a handbook please

I would hesitate to dispute the value of standing and watching, and in fact this is not incompatible with the TECH Method. As you know, in the T-E-C-H sequence, the T, E, and C are visual inspections of the system. It is not until the H (Heat measurements) that we measure temperatures and pressures. By this point I have usually fixed whatever stopped the system, and am now using the numbers to find more subtle additional problems, as well as fine tune the system.

Many see me asking for the numbers online, and assume that this is all it is; A 'by the numbers' method. Wrong. It is much more than that, but when you are trouble shooting online, you can't see it from here. There is no laying on of hands. The numbers are the only means by which the system operation can be communicated.
