1 Each coil distributor requires one thermal
expansion valve (TXV) and one check valve. See
Table 3 and Table 4, p. 21, for
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. 21)
at the indoor unit.
