20OVER 40 FT.CORRECTHigh Wall Mount — For unitsmounted high in the wall, thedischarge louvers should beat a setting that provides themost horizontal air discharge.Recommended installation isat least 3" below the ceiling. Ininstallations where units are close to the ceiling, the greatesthorizontal discharge angle can be obtained by removingthe discharge grille from the room cabinet.Supply Air Throw — One Zoneline unit should not be requiredto do a job obviously requiring two or more units. Unitsshould be located around large rooms according tocalculated loads or in such fashion as to achieve balancedair distribution in all parts of the room. The single unit inthe “Incorrect” illustration below obviously cannot conditionthe entire room. Add a second unit as shown in the“Correct” illustration.Application CommentsUse and Care Manual and installation instructions areshipped with Zoneline ® units. It is important that any airconditioning system be properly sized and applied in orderto achieve the desired temperature and humidity levels inthe space to be conditioned. Zoneline units are designedprimarily to provide heating and cooling with the additionalbenefit that during operation in the cooling mode, the unitsalso remove some moisture from the conditioned space.The following are some brief application comments onundersizing, oversizing, heating, wall coverings, and airinfiltration: all are important in the proper matching of theheating/air conditioning system to the building structure.Undersizing: If an air conditioner is undersized (coolingcapacity is less than required for a specific application), theunit will typically not be able to cool the space down to thedesired temperature (thermostat set point), nor be able toremove enough moisture from the air. A result could be awarm and humid or warm and dry conditioned space.Oversizing: If an air conditioner is oversized (cooling capacityis greater than required for the specific application), the unitwill typically cool the space down to the desired temperature(thermostat set point) too quickly. The compressor thenbegins to cycle on and off. Dehumidification only takes placewhen 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 maintainthe desired temperature level within the conditioned space.Wall Covering: Use of a non-permeable wall covering (somepaints, some wallpapers, and other types of coverings) whichseverely restricts passage of air or water vapor can cause asevere moisture problem. Typical results could be staining ofroom surfaces, wall damage, as well as mold and mildewgrowth in hot/humid climates.Air Infiltration: Excessive air infiltration can magnifyproblems associated with undersizing or oversizing of anair conditioner unit and can be the root cause of insufficientcooling, dehumidification, or heating. Some sources of airinfiltration include vents, gaps around windows and doors,and improperly sealed floor, ceiling and wall joints.Recommendation: For the above reasons it is stronglyrecommended that a professional engineer be retainedto match the Zoneline unit with the building structure.Air DistributionZoneline packaged terminal air conditioners and heat pumpsdischarge air from the top of the unit through reversibletwo-position discharge louvers. Unit discharge louvers arereversed by removing the room cabinet from the unit,removing seven screws that hold the louver section inplace, removing the louver section and rotating it end forend, reinstalling the louver section in the room cabinet withthe seven screws, and reinstalling the room cabinet on theunit. The unit is shipped from the factory with the dischargelouvers at an angle of 50° off vertical. In the alternateposition, the louvers will be at an angle of 40° off vertical.All room cabinets return air through the front of the unit.50° 40°OVER 40 FT.INCORRECT
