Condensate Drain Kit
Part Number 4090661
An indoor/outdoor drain kit is available as an accessory
item. When a drain kit is to be installed, do so before
installing the wall sleeve in the wall.
During periods of high humidity and/or during heat
pump operation, condensate water will collect in the
bottom pan of the chassis. When the chassis bottom pan
is full, the water will overflow into the wall sleeve and out
the drainage holes on the back edge of the wall sleeve.
The Condensate Drain kit contains an overflow tube to
direct excess condensate water from the bottom of the
sleeve to either an internal or external drainage path.
Because heat pumps generate condensate even during
the heating season, it is recommended to always use a
drain kit with heat pump models. Determine whether
the kit should be installed as an internal or external drain
system.
External Drain
Installation
The drain kit can be installed as an external drain on the
left or right side drain opening on the sleeve. Determine
which drain opening will provide the best drainage for
the installation.
Local codes will determine the proper method for con-
densate disposal. The drain kit must be installed before
installation of the wall sleeve condenser grille.
1. Remove the cardboard weather board from the wall
sleeve.
2. Install the outdoor drain fitting and one of the out-
door drain fitting gaskets over one of the drain holes
on the rear of the wall sleeve. Secure this assembly to
the rear of the sleeve with two sheet metal screws into
the holes provided in the wall sleeve.
3. Cover and seal the remaining drain hole using the
remaining outdoor drain gasket, cover plate and
remaining sheet metal screws provided. Periodically
inspect drain passages for blockage. Blow out drain
tubing annually to prevent overflow from entering the
building.
Condensate Drain Kit
NOTE
The external drain kit is intended to be
installed in conjunction with a field-
supplied condensate drain system.
Installing the kit without connecting it to
an external drainage system may result in
inadequate condensate removal, leakage
and/or corrosion.
