Determine the 4-Way Reversing Valve after the use of the same type of four-way valve, replace the first to remove the electromagnetic coil, and then all four-way valve welding.

Pay attention to the first to put the Freon before welding off! Be careful to wrap the towel or toilet paper before soldering! (The effect of toilet paper is better!) A person slowly watering a person welding!

First welding in the middle and then about two, welding fire to be fast! For the 5 4-Way Reversing Valve, welding is a lot of technical difficult work! The first thing to do is to use the big soldering torch! Enough oxygen and gas to get the job done!

Steps are the same as above. After welding, be sure to suppress the system!
You can use both nitrogen and freon! Special reminder: Welding 4-Way Reversing Valve time can not be too long the best one molding! A minimum of two people to complete!
