The HVAC/R Professional's Field Guide to Universal R-410a Safety & Training: Delta-T Solutions (This is a safety and training guide, the cylinder is NOT included)

I love this book. Great explanations and visual graphs,pictures, and charts are easy to follow and understand.

Very good overall reading in 410A and general HVAC procedures and regulations. Enjoyed the concise way that it was presented makes it easy to refer to in the future.

did not recieve replacement in english,, very dissapointed

This manual was just what I wanted. I had been out of the field for a few years and wanted to know all I could learn about R410A and about it's characteristics and origins. (I am installing a new GoodMan 16 SEER airconditioner in my older home and replacing the old.... no more R22, right?) :-) This is about as clear, basic, and cogent information as one can get. It is low cost, and well presented. I feel as if I have had a quick full day , 8 hour, "update" course on R410A and related aesiotropic refrigerants. I heartily recommend this book to anyone who just wants to know more, get some technical and legal details, and yet not wade through a huge technical manual. There things about R410A that - anyone who is planning to work with anything that is R410A filled - needs to know. NOTE: You do need to know what this book presents so simply. This is NOT the old R22 system we all grew up with. Enjoy!

As advertised

A must read if you want to know HVAC/R
