Notes:
1. For applications where the length of the liquid line exceeds 80 ft (24 m) and the heat pump will start in the cooling
mode, remove the liquid-line filter driers from the TWA heat pump and install new filter driers and check valves at the
TWE air handler.
2. Shutoff valves are a field installed option and no longer come standard from the factory.
