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.
