5.4 Reuse existing refrigerant lines

CAUTION:

 If using existing refrigerant lines make certain that all joints

are brazed, not soldered.

For retroﬁ t applications, where the existing refrigerant lines will be used, the

following precautions should be taken:

 Ensure that the refrigerant lines are the correct size. Refer to Section 5.1

listed and Table 2.

 Ensure that the refrigerant lines are free of leaks, acid, and oil.

The manufacturer recommends installing only approved matched indoor

and outdoor systems. All of the manufacturer’s split systems are A.H.R.I.

rated only with TXV indoor systems. Some of the beneﬁ ts of installing

approved matched indoor and outdoor split systems are maximum

eﬃ ciency, optimum per-formance and the best overall system reliability.
