tions with add−on cooling coils require field−fabricated tran- sitions that provide at least 6 inches of clearance for the CBWMV unit’s inlet/outlet water lines. See figure 2 for ex- amples.

*CBWMV units must not be installed horizontally on the front or back of the unit.

Figure 2

Units may be horizontally installed in either attic or crawl space.

CAUTION

CBWMV series units are shipped with an antifreeze thermostat to prevent the water coil from freezing. The freezestat is installed at the factory but must be field wired (see figures 12 and 13). Do not bypass this feature when you install or run the unit.

CAUTION

Use a drain pan for installations over finished living areas.

Either suspend the unit from the roof rafters or floor joists or mount on a platform. The CBWMV unit must be level and well supported.

NOTE − 1/2 hp and 1 hp blower motors are equipped with three flexible legs and one rigid leg. The rigid leg is equipped with a shipping bolt and a flat white plastic wash- er (rather than the rubber mounting grommet used with a flexible mounting leg). The bolt and washer must be re- moved before the air handler is placed into operation. After the bolt and washer have been removed, the rigid leg will not touch the blower housing.

Duct System

Use industry-approved standards (such as those pub- lished by Air Conditioning Contractors of America or Amer- ican Society of Heating, Refrigerating and Air Conditioning Engineers) to size and install the supply and return air duct system. This will result in a quiet and low-static system that has uniform air distribution.

NOTE − Do not operate the air handler with an external static pressure that exceeds 0.8 inches w.c. Higher exter- nal static pressures may cause erratic operation.

Return Air Plenum

IMPORTANT

Return air must not be drawn from a room where any fossil fuel appliance (ie., a water heater) is installed.

When return air is drawn from a room, a negative pres- sure is created in the room. If a fossil fuel appliance is op- erating in a room with negative pressure, the flue prod- ucts can be pulled back down the vent pipe and into the room. This reverse flow of the flue gas may result in in- complete combustion and the formation of carbon mon- oxide gas. This toxic gas might then be distributed throughout the house by the air handler duct system.

CBWMV, AIR HANDLERS specifications

Lennox International Inc is a renowned leader in the heating, ventilation, and air conditioning (HVAC) industry, known for its commitment to innovation and energy efficiency. Among its impressive lineup of products, the CBWMV air handlers stand out as a reliable solution for optimal indoor climate control.

The CBWMV air handler is designed to provide efficient and effective airflow while being easy to install and maintain. One of the key features of the CBWMV model is its variable speed blower motor, which allows for precise control of airflow and temperature. This innovation not only enhances comfort levels within a space but also contributes to significant energy savings. By adjusting the speed of the motor according to the heating or cooling demand, the system operates more efficiently, reducing energy usage by up to 40% compared to conventional systems.

Another important characteristic of the CBWMV air handlers is their compatibility with a range of heating and cooling systems, including heat pumps and gas furnaces. This versatility makes them an ideal choice for residential and commercial applications alike. The unit’s compact design allows for flexible installation options, accommodating various spaces without compromising performance.

The CBWMV series is also engineered to provide superior air quality. With advanced filtration options, these air handlers can effectively remove dust, allergens, and pollutants from the air, promoting a healthier indoor environment. Many models come equipped with a MERV 16 filter, enhancing the filtration capability, and ensuring that occupants breathe cleaner air.

Durability is another hallmark of the CBWMV line. Constructed with high-quality materials, these air handlers can withstand rigorous use and environmental conditions. The units are designed to require minimal maintenance, with features that facilitate easy access for filter changes and routine servicing.

Additionally, the CBWMV series integrates seamlessly with Lennox’s smart technology solutions, allowing users to monitor and control their HVAC systems remotely. The compatibility with home automation systems ensures that users can optimize comfort settings and efficiency with ease.

In conclusion, Lennox International Inc's CBWMV air handlers offer a remarkable blend of efficiency, comfort, and innovative technology. With features that prioritize energy savings, air quality, versatility, and durability, they represent a forward-thinking choice for modern HVAC needs. Whether for residential or commercial use, these air handlers stand as a testament to Lennox's commitment to excellence in indoor climate management.
