Condensate Drain Kit
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 bot-
tom 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
Part Number 6140165
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
outdoor 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.
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.
