Condensate Disposal Pump Kit
Installation
Part No: AYSB2101
Description
The internal condensate pump serves as a means for
disposing of condensate generated during heat pump
operation by transferring it to the indoor coil. The warm coil
surface and the warm room air help in evaporation of the
condensate while adding humidity to the room.
As with any equipment of this type, the addition of this kit will
decrease the effective heating capacity of the unit. This kit is
not intended for use in seacoast or corrosive environments.
NOTE:
Under extreme high humidity conditions, the internal
condensate pump may not be able to dispose of all the
condensate produced, and condensate would then drip from
the outside of the wall sleeve. If this condensation is
unacceptable, then a drain system (including factory
approved drain kit for the wall sleeve) should be installed.
Receiving
Upon receipt of the product, inspect the shipping carton for
signs of visible damage. Report any damage or shortage to

stored in its original shipping carton in a dry, secure place
prior to its installation and use.
Installation
The installation and servicing of the equipment referred to in
