PXDR10 Drain Kit Installation
Instructions (optional for new
construction)
NOTE: Determine whether drain will be located within the wall, on the
indoor side, or will drain to the exterior of the building. Follow
appropriate instructions below depending on your particular
type of installation.
Internal Drain
NOTE: If installing an internal drain, you MUST install a drain kit on
the wall sleeve before the wall sleeve is installed.
1. Refer to Figure 11 and locate the drain within the “Preferred”
area of best drainage.Maintain at least a ½” clearance from the
embossed area.
2. Using the mounting plate with the ½” hole as a template, mark
and drill two, 3/16” mounting holes and a ½” drain hole in the
sleeve bottom.

PREFERRED AREA-
NO FOAM INSULATION
3. Remove the backing from the gasket and mount it on the flat
side of the mounting plate (See Figure 12, Page 11). Insert the
drain tube through the hole in the gasket and mounting plate so the
tube flange will be against the wall sleeve.
4. Position the assembly beneath the drilled holes and secure it with
#10-24 x ½" machine screws and lock nuts provided. Seal the tops
of the screws with silicone caulking.
5. Use ½" I D copper tube, PVC pipe, or vinyl hose (obtained locally)
to connect the internal drain tube to the drain system in the building.
6. Referring to Figure 12, Detail A, Page 11, locate and assemble
the two cover plates and gaskets over the drain holes at the
rear of the wall sleeve. Attach them with the #10 sheet metal
screws provided. Make certain that the four overflow slots at
the rear of the wall sleeve are not blocked (See drawing of the
back of the sleeve Figure 12, Page 11).
7. If a deep wall extension (PDXWSEXT) is used, after installing the
field supplied flashing,caulk as required. Be sure to caulk around
the flashing and the wall sleeve where the hole was drilled for the
drain tube.
