Care and cleaning.
Base Pan
In some installations, dirt or other debris may be blown into the
unit from the outside and settle in the base pan (the bottom of
the unit).
In some areas of the United States, a naturally occurring
“gel-like” or “slime-like” substance may be seen in the base pan.
Check it periodically and clean, if necessary.
On 4500 Series models, do not remove the rubber drain plug
from the basepan. If removed, excess water may drain to the
outside.
Ventilation Filter
If the vent door is open, clean the vent filter twice a year or as
required. Access requires the removal of the unit from the wall
sleeve.
Turn the Zoneline off and unplug before removing and cleaning.
To clean the vent filter:
IMPORTANT:
This filter is not removable. Trying to remove this filter will
damage the unit.
■
Use a vacuum to remove debris from the filter.
■
Use a damp rag to wipe down the filter and surrounding area
after vacuuming.
Outdoor Coils
The coils on the outdoor side of the Zoneline should be checked
regularly. If they are clogged with dirt or soot, they should be
cleaned by either low or no pressure cleaning methods. Ensure
that electical area/devices are protected during cleaning. You will
need to remove the unit from the wall sleeve to inspect the coils.
The dirt buildup occurs on the fan side of the outdoor coil.
Clean the outside coils regularly.
Room Cabinet and Case
Turn the Zoneline off and disconnect the power supply.
To clean, use water and a mild detergent.
Do not use bleach or abrasives. Some commercial cleaners may
damage the plastic parts.
