Good day everyone! KINDLY ADVISE PLEASE.

I have a DUNHAM BUSH (Model: ACPSB 1340 PQ) Package Unit I just inspected, I observed that the TXVs have been removed from the unit.

The unit has 4 circuits, each circuit has 2 compressors.

Circuits 1, 2, 3 have 2 compressors model ZR160KC-TFD-425 each
Circuit 4 has 2 compressors model: ZR190KC-TFD-425

PLEASE HOW DO I KNOW THE RIGHT TXVs TO INSTALL IN THIS UNIT SINCE THE ONES THAT CAME WITH THE UNIT HAVE BEEN REMOVED.

THANK YOU.
