Installation

Installation Preparations

The final position for the air handler must be dictated by required service access to it, weight distribution over structural supports, and by the locations of electrical, refrigerant and condensate drainage connections. After this is determined, the following preparations should be made.

Repositioning Drain Pan

These air handlers come with one drain pan that can be installed in any one of four positions; this allows for vertical or horizontal application and right or left condensate line connection. The drain pan can also be easily removed for periodic cleaning.

Note: Important! All air handlers are shipped with the drain pan installed in the horizontal position and the connection on the left side (as shown in Figure 4). If an alternate position is required, the drain pan should be repositioned before setting the air handler.

Figure 4.

Process for Drain Pan Relocation

1.Remove the access plate at the opposite end of the drain connection. This plate secures and lifts the back end of the drain pan for sloping. It must be removed before the drain pan can be removed. This is done as follows:

a.Remove the screw

b.Lift the access plate up

c.Pull the plate out. If the drain pan is to be moved to the

vertical position also remove the other two access plates.

2.Remove the screw securing the

drain pan.

a.Lift the pan up

b.Slide the pan out

3.Install the drain pan into the new position.

a. Slide the drain pan into the opening

b.Lift the drain pan up

c.Push it in all the way

d.Drop it down over the lip of the opening, secure with screw

4.Install the access plate on the opposite end of the drain pain.

a.Slide the edge of the access plate under the drain pan

b.Lift the access plate and drain pan up

c.Push the access plate in

d.Drop the access plate down over the lip of the opening,

secure with screw. If the

drain pan is being moved to Figure 5. the vertical position, install

the other access plates over the horizontal position opening.

TWE060B***E, TWE060A***E, TWE050AD**E, TWE200BD**F, TWE120A***F specifications

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.
