Application Comments
Use and Care Manual and installation instructions are
shipped with Zoneline units. It is important that any air
conditioning system be properly sized and applied in order
to achieve the desired temperature and humidity levels with
the space to be conditioned. Air conditioners are designed
primarily to provide heating and cooling with the additional
benefit that during operation in the cooling mode, the units
also remove some moisture from the conditioned space. The
following are some brief application comments on
undersizing, oversizing, heating, wall coverings, and air
infiltration: all are important in the proper matching of the
heating/air conditioning system to the building structure.
Undersizing: If an air conditioner is undersized (cooling
capacity is less than required for a specific application), the
unit will typically not be able to cool the space down to the
desired temperature (thermostat set point), nor be able to
remove enough moisture from the air. A result could be a
warm and humid or warm and dry conditioned space.
Oversizing: If an air conditioner is oversized (cooling
capacity is greater than required for the specific
application), the unit will typically cool the space down to
the desired temperature (thermostat set point) too quickly.
The compressor then begins to cycle on and off.
Dehumidification only takes place when the compressor is
operating. A typical result in a hot/humid climate could be
a cool, but excessively humid space.
Heating: Undersizing can result in not being able to
maintain the desired temperature level within the
conditioned space.
Wall Covering: Use of a non-permeable wall covering (some
paints, some wall papers, and other types of coverings)
which severely restricts passage of air or water vapor can
cause a severe moisture problem. Typical results could be
staining of room surfaces, wall damage, as well as mold and
mildew growth in hot/humid climates.
Air Infiltration: Excessive air infiltration can magnify
problems associated with undersizing or oversizing of an air
conditioner unit, and can be the root cause of insufficient
cooling, dehumidification, or heating. Some sources of air
infiltration include vents, gaps around windows and doors,
and improperly sealed floor, ceiling and wall joints.
Recommendation
For the above reasons it is strongly recommended that a
professional engineer be retained to match the Zoneline
with the building structure.

Air Distribution
Zoneline packaged terminal air conditioners and heat
pumps discharge air from the top of the unit through
reversible 2-position discharge louvers. Unit discharge
louvers are reversed by removing the room cabinet from the
unit, removing seven screws that hold the louver section in
place, removing the louver section and rotating it end for
end, reinstalling the louver section in the room cabinet with
the seven screws, and reinstalling the room cabinet on the
unit. The unit is shipped from the factory with the discharge
louvers at an angle of 50° off vertical. In the alternate
position the louvers will be at an angle of 40°
off vertical.
All room cabinets return air through the front of the unit.

High Wall Mount - For units
mounted high in the wall, the
discharge louvers should be at a
setting that provides the most
horizontal air discharge.
Recommended installation is at
least 3" below the ceiling. In
installations where units are
close to the ceiling, the most
horizontal discharge angle can
be obtained by removing the
discharge grill from the room
cabinet.
Supply Air Throw - One
Zoneline unit should not be
required to do a job obviously
requiring two or more units.
Units should be located around
large rooms according to
calculated loads or in such
fashion as to achieve balanced
air distribution in all parts of
the room. The single unit in
the “Incorrect” illustration
below obviously cannot
condition the entire room. Add
a second unit as shown in the
“Correct” illustration.
