Condensate Drain Kit - DK900*
(Combination Drain Kit...for outdoor or indoor sleeve drainage.)
Description
This kit is used to control condensate from the unit. Con-
densate water drains from the chassis into the sleeve
during normal heat pump operation and during times of
high humidity when the unit is in cooling operation. The
drain kit allows the condensate from the outdoor and
indoor coils to be routed to a suitable area. It can be
installed for either outdoor or indoor use. For outdoor use,
the condensate can be drained from either the right- or left-
hand side of the wall sleeve. Local codes will determine the
proper condensate disposal. For indoor use, the drain
components must be installed on the bottom of the wall
sleeve and connected to a drain system inside the building.
NOTE: This drain kit serves only as a link between the unit
and field-supplied condensate drain system. Installing the
kit without connecting it to a drainage system will result in
inadequate condensate removal, possible leakage and
corrosion.
ALGAECIDE: Most algaecide products will cause dam-
age to the unit basepan or coils and should not be used.
Contact your sales representative for the recommended
algaecide pan treatment for your unit.
The installation and servicing of the equipment should be done by qualified experienced technicians.
Drain Kit Components
Installation for Outdoor Use
The drain components for outdoor use must be installed
before the wall sleeve condenser grille.
1. Remove the rear enclosure panel and the sleeve
stiffener. NOTE: These items can be removed from
the inside of the building.
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 using two of the provided
outdoor mounting screws.
3. Cover and seal the remaining drain hole using the
remaining outdoor drain gasket, blank-off plate and
outdoor screws.

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 connected to an indoor
drainage system immediately after the wall sleeve is
installed; 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 as
shown in the figure above. 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.

Description
Theinternal condensatepump servesas aneffective means
for disposing of condensate generated during heat pump
operationbytransferringitto the indoor coil. The warm coil
surface and the warm room air help in evaporation of the
condensatewhile adding humidity to the room. As with any
equipment of this type, the addition of this kit will decrease
the sensible heating capacity of the unit. This kit is not
intendedfor use in seacoast or corrosive environments.
NOTE: Underextreme high humidityconditions, the internal
condensatepump may not be able to dispose of allthecon-
densateproduced, andcondensate wouldthendrip fromthe
outsideof the wall sleeve. If this condensation is unaccept-
able, then a drain system (including factory approved drain
kit for the wall sleeve) should be installed.
