the exterior of the house. If it has not already
been done, also pass the end of the DIYPRO™

NOTE ON DRAINPIPE OUTLET
The drainpipe should exit the wall hole and
run in a way that allows the condensate to
flow freely and be discharged from the outlet
onto the ground. The drainpipe outlet should
be at least 1.9 in (5 cm) above the ground. If
the drainpipe touches the ground it could
become blocked and cause the unit to
malfunction. If you discharge the condensate
directly into the sewer, ensure that the drain
has a U or S pipe to catch any odors that
might otherwise come back into the home.
Please refer to Figs. 5.22a - 5.22d on the right
as a guide when determining how the
drainpipe should exit your application.
Make sure there are
NO kinks or dents in
the hose to ensure
proper drainage .
