holes (A).

Cut 2 sections of plastic tubing, about 12"
(305 mm) long and attach them to each drain
fitting. Join the 2 short sections to the "T"
junction and main tube as shown.
VO0091
In order to keep the drain pan intact, hand
tighten the 2 plastic drain fittings to the unit
door using the gaskets and nuts as shown.
VO0093
Make a water trap loop in the tube to prevent
the unit from drawing unpleasant odors from
the drain source. Make sure this loop is
situated BELOW the "T" as shown. This will
prevent water from being drawn back up into
the unit in case of negative pressure. Run the
tube to the floor drain or to an alternative
drain pipe or pail. Be sure there is a slight
slope for the run-off.
