Installation for Indoor Use
The components of the wall sleeve drain kit for indoor use are shown in figure below.
These components must be
installed prior to the installation of the wall sleeve.
1. Locate an area on the wall sleeve that will be inside the
room when the sleeve is installed. If a subbase is
installed, locate the kit a minimum of 3 1/2” from the
front flange of the wall sleeve. This clearance will
provide adequate clearance for the subbase.
2. Cutout the template shown to the right. Using this
template, locate and drill the drain kit holes as close to
the outside wall as possible.
3. Using detail A (above) as a guide, assemble the drain
gasket, drain fitting plate, and indoor drain fitting to-
gether. Install the assembly into the drilled holes and
secure using the two indoor mounting screws pro-
vided. The screws must be inserted INSIDE the wall
sleeve and TOP driven down into the drain fitting plate.
Ensure drain tube is not restricted. Cover the two
screw heads with a good quality outdoor caulking (not
supplied) for additional corrosion protection.
NOTE:
If the drain fitting is not immediately connected
to an indoor drainage system after the wall sleeve
installation, plug the hole with cork (not included) to
prevent indoor water damage in case it rains.
4. Install a 1/2” ID tube or hose (not included) on the drain
fitting and interconnect it to the drain system inside of
the building. Ensure that there are no kinks or traps in
tube or hose. Kinks or traps can cause improper
drainage.
5. Install the two drain blank-off plates and outdoor drain
gaskets on the outdoor portion of the wall sleeve.
These components can be installed after the sleeve is
secured in the wall opening just prior to the installation
of the condenser grille and chassis.
