, posted Wed 25 Jun 13:05  
Greetings,
Given an air handling unit that can be converted to use R22 or R410A. What changes are needed to do the conversion? The TXV obivously but anything else? My unit is a Trane 2TEC3F60A (R22 type) that was mistakenly installed on a 4TWR3060A compressor (R410type).The plan is to replace the TXV with the one for the correct refrigerant. I am curious as to whether this is the only difference in those units.
Thanks,
ebc

the only thing should be the txv as long as the indoor coil can do 410? make sure you braze the joints do to purons higher pressures
