Installation

Note: Important! When air handler is installed in the vertical position and close proximity trapping of condensate is required, use of a subbase accessory to raise the air handler for clearance of the drain trap is recommended. See Figure 6 for a typical drain trap assembly

.

Filters

Air handlers are shipped with throwaway filters installed. For replacement filters consult the air handler service facts for correct size and number. To replace filters from the end of the unit, remove lower access panel (either end) and slide old filters out and replace with new ones. To replace from the front of the unit, remove one "L" shaped angle. Remove and replace filters and reinstall "L" shaped angle. See Figure 7.

.

Figure 7.

To convert from 1" filter to a 2" filter on units so equipped, remove lower access panels from both ends of the air handler. Remove screws and reposition the "L" shaped angles from both the top and bottom of the

filter track to increase the width of the filter opening.

Duct Connections

The supply and return ducts should be connected to the unit with flame retardant duct connectors to reduce vibration transmission. The return duct should be sized to the same dimensions as the return inlet of the unit.

Note: Important! Duct flanges are provided for attachment of the duct work. On TWE060, 090, and 120 the flanges are not installed but are shipped inside the air handler. While facing the air handler with the control box to your left, remove the upper access panel. The duct flanges will be attached to the belly band of the air handler nearest you. Remove the screws securing flanges in place. Position the four flanges around the supply opening. Secure with field supplied screws, using the predrilled holes. On TWE180 and 240, the duct flanges are packaged on the outside of the cabinet.

Air Flow Settings

Unit is shipped for nominal airflow with nominal static pressure. Please refer to fan performance table in either the product catalog or unit service facts and select the proper drive package for each application. Failure to do so could result in improper airflow causing coil frosting or condensate management problems. Condensate management problems such as water drip off or water blow off could be the result of too great of air face velocity across the coil.

￿WARNING

Hazardous Voltage w/Capacitors!

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Note: For additional information regarding the safe discharge of capacitors, see PROD-SVB06A-EN or PROD-SVB06A-FR.

The American Standard TWE series of air handlers, including models TWE180B***E, TWE075AD**E, TWE100BD**E, and TWE240B***F, represent a blend of robust engineering, energy efficiency, and advanced technology designed to meet a variety of climate control needs in residential and light commercial settings.

One of the standout features of these air handlers is their adaptability to both cooling and heating functions, particularly the heat pump configurations. This dual functionality makes them ideal for regions with fluctuating temperatures, providing comfortable indoor environments year-round. The TWE series can efficiently maintain desired temperatures, whether in cooling mode during hot summers or heating mode in colder months.

Energy efficiency is a hallmark of the TWE models. Many of these air handlers are equipped with high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings, ensuring that energy consumption is kept to a minimum. This not only contributes to lower utility bills but also aligns with contemporary environmental standards.

The TWE240B***F model exemplifies American Standard's commitment to quiet operation. Noise reduction features, such as insulated cabinets and optimized fan designs, ensure that the unit operates quietly, making it suitable for residential areas where noise can be a concern.

Durability and reliability are key characteristics of the TWE series. Constructed with high-quality materials, these air handlers are designed to withstand the rigors of varying weather conditions. Many units also come with extensive warranties, underscoring the confidence in their longevity and performance.

Installation flexibility is another advantage of the TWE series. These air handlers can be configured for horizontal or vertical applications, allowing for versatile installation options in different home layouts.

The TWE models are also compatible with advanced thermostats and zoning systems, enabling homeowners to optimize comfort and efficiency based on their specific needs. Smart technology integration further enhances control over indoor climates, ensuring that users can manage their environment conveniently.

In summary, the American Standard TWE series air handlers—TWE180B***E, TWE075AD**E, TWE100BD**E, and TWE240B***F—combine energy efficiency, versatility, quiet operation, and long-lasting durability. These features make them an excellent choice for those seeking reliable cooling and heating solutions in their homes or small commercial spaces.
