Feed the drain tube through, and
from the front of the unit,
connect the drain tube to the
drain spout in the upper left
portion of the water tank cavity.
When the drain tube is fully
inserted, this adapter piece sticks
out. This piece is threaded so that
it can fit a low pressure garden
hose. In the picture the treaded
piece is not screwed in, but you
would screw it in with one screw
at 3 o’clock and one screw at 9
o’clock
