Filter Driers: Single-flow filter driers (B1219212, B1219225) are integral for removing moisture and contaminants from the refrigerant circuit, protecting the compressor and expansion device.
Compressor Grommets: Grommets (B1339530, B1339533, 0164M00000P) are used to isolate compressor vibration and reduce noise.
Flow Check Pistons: Various flow check piston kits (e.g., B1789855, B1789874) are specified, likely for optimizing refrigerant flow in different operating conditions or system configurations.
Condenser Coils and Tubing: The manual lists various tubing assemblies for condenser coils (e.g., 0201R00177S, 1362100-1362106), indicating that these are replaceable components if damaged or leaking.
Louvered Side Panels: These panels (e.g., 0121R00014PDGB, 0121R00025PDGB) protect the condenser coil while allowing airflow.
Venturi Rings: Venturi rings (0161L00000, 0161R00007P) are used to optimize airflow through the fan, improving efficiency and reducing noise.

The "Text Codes" section clarifies the meaning of abbreviations used in the parts list, such as AR (As Required), NA (Not Available), NS (Not Shown), QTY (Quantity), and M (Model), which are essential for accurate parts ordering and maintenance.
