Application: Used for branching and connecting outdoor units in heat recovery systems (paired with companion kits like RBM-BT24FUL).
Orientation Rules:
Suction gas joints must be mounted horizontally (with a maximum gradient of ±15°).
Discharge gas, liquid, and balance pipe joints have no orientation restrictions, provided the main pipe does not flow directly into a header unit.
Brazing Requirements: Must be purged with nitrogen prior to brazing to prevent oxidation scale and system cycle clogging; use clean, new R410A pipes.
Insulation: Joints must be individually insulated; use heat resistance rated at ≥248°F for discharge gas pipes and a thickness of ≥0.4" for seams and T-joints.
