5. Inspect and clean the face of the coil. Sharp edges are present on the fins and coils .
6. Reinstall the filter.
7. Replace the 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.
Flushing a water regulating valve – water-cooled models only
To clear any sediment that may accumulate,
valves may be manually flushed by inserting
screwdrivers under both sides of the main
spring and lifting upwards to flush the valve.
Manual flushing does not affect valve
adjustments.
Cleaning the Humidifier (optional)
I
f 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 standard heat/cool 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.
No additional maintenance is required for the heating coil. To test the heating coil operation, set
the thermostat on HEAT and set the temperature above the space temperature. The supply air
temperature should rise above the return air temperature by an amount shown in the
specifications.
