General Information

General

This manual covers installation of the TWE050, 060, 075, 090,100 and 120A single circuit air handlers and TWE060, 075, 090, 100, 120, 155, 180, 200 and 240B dual circuit air handlers. These air handler models incorporate a single slab coil assembly, improved application flexibility, servicing, maintenance accessibility and an improved accessory line. They are fully convertible, (vertical to horizontal discharge) without field removal or reorientation of the coil assembly. They are shipped ready for horizontal installation.

The TWE090A300C, TWE090B300C, TWE120A300D, TWE120B300D models are shipped from the factory wired for 208-230V/3ph/60 Hz, but may be field converted for 460V/3ph/ 60 Hz applications by changing voltage plug on the motor. For voltage change plug instructions, refer to Figure 9.

All units (both single and dual circuit), have one drain pan that can be installed in any one of four positions. This allows for vertical or horizontal applications and right or left exit.

Note: The TWE060B, TWE090B, TWE100B, and TWE120B dual circuit air handlers have a split face coil. When they are installed in either position, the lower half of the coil is designated as “Circuit A” and should always wet first.

The TWE155B, TWE180B, TWE200B dual circuit units have a mixed face coil.

Note: Note: The TWE050, 060, 075, 090, 100 and 120 air handlers have structural provisions to allow 180 degree rotation of discharge panel/blower assembly at installation. A reversible discharge wiring kit, BAYWRKT001A is available with instructions.

Installation procedures should be performed in the sequence that they appear in this manual. Do not destroy or remove the manual from the unit.

The manual should remain weather- protected with the unit until all installation procedures are complete.

Note: It is not the intention of this manual to cover all possible variations in systems that may occur or to provide comprehensive information concerning every possible contingency that may be encountered during an installation. If additional information is required or if specific problems arise that are not fully discussed in this manual, contact your local sales office.

Note: "Warnings" and "Cautions" appear at appropriate places in this manual. Your personal safety and the proper operation of this machine require that you follow them carefully. The Company assumes no liability for installations or servicing performed by unqualified personnel.

Installation Checklist

An "Installation Checklist" is provided at the end of the installation section of this manual. Use the checklist to verify that all necessary installation procedures have been completed. Do not use the checklist as a substitute for reading the information contained in the manual. Read the entire manual before beginning installation procedures.

Unit Inspection

Inspect material carefully for any shipping damage. If damaged, it must be reported to, and claims made against the transportation company. Compare the information that appears on the unit nameplate with ordering and submittal data to insure the proper unit was shipped. Available power supply must be compatible with electrical characteristics specified on component nameplates. Replace damaged parts with authorized parts only.

Inspection Checklist

To protect against loss due to damage incurred in transit, complete the following checklist upon receipt of the unit.

[ ] Inspect individual pieces of the shipment before accepting the unit. Check for obvious damage to the unit or packing material.

[ ] Inspect the unit for concealed damage before it is stored and as soon as possible after delivery. Concealed damage must be reported within 15 days. If concealed damage is discovered, stop unpacking the shipment. Do not remove damaged material from the receiving location. Take photos of the damage if possible. The owner must provide reasonable evidence that the damage did not occur after delivery.

[ ] Notify the carrier’s terminal of damage immediately by phone and by mail. Request an immediate joint inspection of the damage by the carrier and the consignee.

[ ] Notify the sales representative and arrange for repair. Do not repair the unit until the damage is inspected by the carrier’s representative.

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.
