Condensate Drain
A condensate drain is provided to divert excess water when air
conditioner is installed over a doorway or sidewalk.
1. Pry cap plug from the condensate drain (located on underside of
bottom pan). Use a 3/8" pipe tap and fully thread the condensate
drain (Fig. 20).
2. Screw a 3/8" pipe fitting into the condensate drain. The fitting
should be protruding approximately 1/2" above the bottom pan
when fully threaded into the condensate drain (Fig. 21).
3. If an open drain source is used to dispose of condensate, plastic or
rubber tubing may be run directly from the pipe fitting to the open
drain source. If closed drain source (internal structural plumbing) is
used, a "P" trap must be between the 3/8" pipe fitting and the
closed drain source (Fig. 22).
Consult your authorized dealer or
importer
for alternative
installation instructions.
Caution: Do not drill a hole in bottom pan. Unit is designed to
operate with approximately 1/2" of water in bottom pan.
Do not remove the cap plug, unless the condensate drain is
used.
