the drain hole which best meets your drainage situation and install the drain kit. Seal off the other with a cover plate.

Peel the backing tape off the gaskets and apply the sticky
side to one cover plate and one mounting plate as shown
in Details A and B,

Place the drain tube through the gasket and the mounting
plate with the flange toward the wall sleeve.
3.
Attach the drain tube assembly to one of the two drain
holes at the rear of the wall sleeve. The large flange on
the mounting plate is positioned atthe bottom of the sleeve
facing toward the sleeve, Detail B. When the drain tube is
positioned at the desired angle, tighten the screws.
