Cleaning the Filters
The evaporator and condenser coils are provided with reusable, washable air filters. The
filters protect the coils from becoming coated or plugged by dust. Frequency of cleaning the
filters is based on the amount of dust or dirt generated in the cellar or basement.
1.
Remove the grille or duct collar on the inlet end of the unit.
2.
Remove the filter covering the face the coil.
3.
Wash it under warm water.
4.
Shake off excess water.
5.
Inspect and clean the face of the coil.
CAUTION
SHARP EDGESRISK OF SERIOUS INJURY
Sharp edges are present on the fins and coils.
6.
Reinstall the filter.
7.
Replace the grille or duct collar.
Cleaning the Condensate Drain System
The condensate drain system traps dust and dirt. Clean the drain system once a year.
1.
Shut off the rocker switch and unplug the unit.
2.
Remove the grille or duct on the evaporator inlet.
3.
Remove the filter and inspect the drain pan under the coil.
4.
If drain pan appears soiled, pour some hot water mixed with liquid bleach (diluted
solution) along the length of the pan to flush the dirt down the drain tube.
5.
Continue this treatment until the drain appears clean and free of dirt.
6.
Reinstall filter and grille or duct collar.
7.
Plug in the unit and restart.
Cleaning the Humidifier (optional)
If the unit was furnished with a humidifier it requires periodic maintenance. Follow the
instructions in the humidifier guide.
Heating Coil Option
The heating coil is located between the evaporator coil and blower inside the transition duct. It
contains the heating element and high temperature limit switches. The heating coil is wired to
work in conjunction with the thermostat. Since the thermostat prevents the heating and
cooling circuits from being energized at the same time, no additional power wiring is needed.
We do recommend using the AUTO mode on the thermostat so it can switch from heating to
cooling automatically. If using either the heat or cool only mode, the thermostat will
not
switch automatically.
