PRE-INSTALLATION

Unpack and Inspect Units — Remove shipping wraps from all units. Check the shipment against shipping order. Make sure that furnished only items, such as thermostat, grilles, etc., are accounted for, whether packaged separately or shipped at a later date. If shipment is damaged or incomplete, file claim with transportation company and advise Carrier im- mediately.

Protect Units from Damage — The equipment must always be properly supported. Temporary supports used during installation or service must be adequate to hold the equipment securely. Equipment should always be stored in the proper ori- entation as marked on the carton. To maintain warranty, protect units against adverse weather, theft, vandalism, and debris on jobsite. Equipment covered in this manual is not suitable for outdoor installations. Do not allow foreign material to fall into drain pan. Prevent dust and debris from being deposited on mo- tor and fan wheels. Manufacturer's warranty is void if foreign

material is allowed to be deposited on the motor or blower wheels of any unit.

Prepare Jobsite for Unit Installation — To save time and to reduce the possibility of costly errors, set up a com- plete sample installation in a typical room at jobsite. Check all critical dimensions such as pipe, wire, and duct connection requirements. Refer to job drawings and product dimension drawings as required (see Fig. 1-36). Instruct all trades in their part of the installation.

Identify and Prepare Units — Be sure power require- ments match available power source. Refer to unit nameplate and wiring diagram.

1.Check all tags on unit to determine if shipping screws are to be removed. Remove screws as directed.

2.Rotate the fan wheel by hand to ensure that the fan is unrestricted and can rotate freely. Check for shipping damage and fan obstructions.

Carrier 42V, 42C, 42S, 42D specifications Pre-Installation

42V, 42D, 42S, 42C specifications

Carrier has established itself as a leader in the HVAC industry by continuously innovating and refining their products. Among their offerings, the Carrier 42D, 42C, 42S, and 42V series stand out for their advanced features, efficient technologies, and user-friendly characteristics.

The Carrier 42D series is known for its robust and energy-efficient design, making it ideal for commercial applications. This series employs a high-performance scroll compressor that enhances efficiency while minimizing noise levels. Equipped with advanced controls, the 42D allows for precise temperature management, ensuring comfort in a variety of environments. Its compact design is another notable feature, allowing for easier installation in constrained spaces while still delivering excellent performance.

Similar to the 42D, the 42C series emphasizes energy efficiency, but it comes with additional features tailored for residential applications. One of the main highlights is its variable-speed compressor technology, which provides exceptional temperature control and reduces energy consumption. This series also includes enhanced filtration systems, ensuring cleaner air quality, which is particularly important for allergy sufferers. Moreover, the 42C's intelligent control systems simplify operation and allow users to customize settings according to their preferences.

The Carrier 42S series focuses on environmentally friendly refrigerants, aligning with global sustainability trends. This series utilizes R-410A refrigerant, which has a lower impact on the ozone layer compared to traditional refrigerants. In addition to its eco-friendly attributes, the 42S boasts features such as an integrated humidity control system, which modulates humidity levels effectively, improving overall indoor air quality.

Finally, the 42V series presents a versatile solution for customers looking for advanced technology and adaptability. With smart connectivity features, the 42V allows for remote monitoring and control via mobile apps, enhancing user convenience. This series is also equipped with a state-of-the-art inverter compressor, which adjusts its speed according to the heating or cooling demand, resulting in significant energy savings.

In summary, the Carrier 42D, 42C, 42S, and 42V series each offer unique features and technological advancements that cater to the diverse needs of users in both residential and commercial settings. With a focus on energy efficiency, user-friendly controls, and environmentally sustainable practices, Carrier continues to set the standard in HVAC solutions.
