Always check that the drain cap is installed to the unused drain port and is fastened with the nylon
fastener. If the drain cap is not installed, or is not sufficiently fastened by the nylon fastener, water
may drip during the cooling operation.
(9) Be sure to insulate where the drain port and the drain hose is connected
(Fig. 4.26).
(10) The unused drain port also should be insulated properly (Fig. 4.27).
