INSTALLATION
External Drain
11
External Drain (for new
construction or unit
replacement)
When using an external drain system, the condensate is removed through
either of two drain holes on the back of the wall sleeve. Select the drain
hole which best meets your drainage situation and install the drain kit.
Seal off the other with a cover plate.
Drain Tube Installation (See Figure 12)
1. 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.
2. 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 at the bottom of the sleeve facing toward the sleeve,
Detail B. When the drain tube is positioned at the desired angle,
tighten the screws.
Cover Plate Installation
4. Mount the foam gasket to the cover plate. Using two #10 x ½" sheet
metal screws (provided), attach the cover plate to the remaining
drain hole. Make certain the large flange on the plate is positioned
at the bottom of the sleeve.
5. Discard the additional cover plate, gasket, machine screws, and
locknuts.
NOTICE
If the wall sleeve has not been installed, the drain tube
must be rotated to a horizontal position until after the
sleeve is installed. Tighten the mounting plate screws
when the tube is in the proper position. Make certain that
the four overflow slots at the rear of the wall sleeve are not
blocked (See Figure 12).
When sealing the sleeve on the outside of the building, be
careful NOT to let the sealant block the two condensate
drain holes or the four overflow slots at the bottom flange
of the sleeve.
Potential property damage can occur if instructions are
not followed.

NOTE: The large flange on the mounting plate is positioned at the bottom of the sleeve facing toward the sleeve. The drain tube must be rotated to a
horizontal position to allow for the wall sleeve to be installed into the wall. Once the wall sleeve is installed, return the drain tube to a downward
angle.
