Condensate Disposal Pump Kit
The internal condensate pump serves as an effective 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 humid-
ity 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 intended for use in seacoast or corro-
sive 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.
Preparation
1. Remove front by rotating bottom outward and then lifting
up and out from chassis.
2. Unplug and remove the PTAC chassis from the wall
sleeve. Move the chassis where the front and back of the
chassis can be easily accessed.
3. Remove the discharge screen by unscrewing two screws
holding the screen to the blower panel. Set screen aside
(Figure 1).
