WATER DRAINAGE - Precipitation entering the unit through the outdoor louver may not be removed entirely by the
condensate removal system. The base pan flange is designed to allow excess water, either condensate water or
precipitation, to flow into the wall case and drain through two drain holes in the rear of the wall case. If there is more
water in the wall case than can be drained through these holes it will drain through the three overflow drain holes.
These drain holes must not be blocked when mounting or caulking the wall case.
For those installations where water draining from the drain holes is objectionable or where positive drainage is
desired, the RAD10 drain kit is available with either a 90° elbow or a 6” straight tube to be used either to connect to a
field supplied drain line or to allow the water to drip free rather than drain down the surface of the building.
NOTE: Drain kit using either the 90° elbow tube or the straight tube may be installed without modification when using
RAG60 exterior grille. Drain kit using the 90° elbow tube may be installed without modification when using RAG61
through RAG66 exterior grilles. Modification must be made to the RAG61 through RAG66 exterior grilles when using
the straight tube. Modification must be made to the RAG67 grille if using either the 90° elbow tube or the straight tube
(see installation instructions with the RAG67 grille).
