1. The RAD10 drain kit is installed in the
bottom of the wall sleeve when it is desired to drain condensate to an internal drain system in the building.
2. The drain kit is mounted on the bottom
of the wall sleeve prior to installation of the sleeve in the wall. It may be located an where on the room-side portion except for sub-base installations. For these the drain should be at least 3" from the indoor edge of the sleeve so as to adequately clear the sub-base.
3. A template is furnished with the kit for
locating the necessary three holes in the sleeve bottom —two to provide a securing means and one to provide a drain hole for the 1/2" OD tubing (see details at left). Paint raw edges of drilled holes with rust preventive paint.
4. A tube or hose 1/2" I.D. (obtained locally)
must be installed on the drain tube and connected to the internal drain system in the building.
5. With the RAD10 the two square drain holes
in the bottom outer flange of the wall sleeve are sealed by the gaskets and mounting plates shown above.
6. Two 1/2" diameter holes located 1/4" above
the sleeve bottom in the bottom outer flange provide overflow drainage to the outdoors when wind-driven rain enters the chassis.
NOTE: If using RAD10 internal drain kit with an integral window louver system special attention should be paid to: • Allowance for drainage from overflow drain
holes in rear flange of wall sleeve.
• Alternative methods for sealing square
drain holes (and associated screw holes) in rear corners of the wall sleeve. The RAD10 drain kit will interfere with the seal and fit of the sleeve to the inside face of the integral window louver system.
• Sealing of wall sleeve to the building structure
(see wall sleeve installation instructions) and integral window louver system to prevent the elements from entering the structure.
