5.4 Reuse Existing Refrigerant Lines
CAUTION: MINOR TO MODERATE BURNS
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 2.2
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 AHRI
rated only with TXV indoor systems. The benefi ts of installing approved
matched indoor and outdoor split systems are maximum effi ciency,
optimum performance and the best overall system reliability.
