Figure 10. TWA heat pump and matched indoor coil (typical arrangement shown in cooling mode)
Notes:
1. Each coil distributor requires one thermal expansion valve (TXV) and one check valve. See
recommendations.
2. 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
(Table 3, p. 26) at the indoor unit.
3. Shutoff valves are a field installed option and no longer come standard from the factory.
