E F G FEATURES BLOWER Power Saver Constant Torque Blower Motor Programmable high efficiency multi-speed blower motor. By maintaining constant torque output, blower motor can deliver more uniform (but not constant) airflow over the static pressure range. Programmable multi-speed operation is achieved by the use of an ECM (Electronically Commutated Motor) motor. Leadless blower motor features simple plug-in connections. Choice of blower speeds is available. See Blower Data tables. Blower speed change is easily accomplished by a simple wiring change. Blower Assembly Lennox designed and built, direct drive blower. Each blower is statically and dynamically balanced as an assembly before installation in the unit. Blower motor is resiliently mounted to blower assembly. Blower slides out of cabinet for servicing. CABINET Constructed of heavy-gauge galvanized steel. Completely insulated with thick fiberglass insulation. Pre-painted steel cabinets have mildly textured enamel finish with primer coat on unpainted side of all panels. Units are shipped in one piece but may be disassembled into two separate sections for ease of installation in tight applications. See dimension drawings. Thick rubber gasket between sections of the two piece cabinets provides an air tight seal. No external screw heads on sides of cabinet for tight installations without damage to walls or woodwork. Removable panels provide complete service access. Electrical inlets provided in sides and top of cabinet. See dimension drawings for locations.

I FEATURES INDOOR AIR QUALITY Air Filter Tool-less access to filter area for quick and easy servicing. Disposable frame type filter furnished and factory installed in rails in cabinet. See Specifications tables for sizes. Optional Accessories Healthy Climate Germicidal UVC Light Germicidal lamp emits C-Band ultra-violet (UVC) energy at.7 nanometers, which is proven to be effective in reducing microbes such as viruses, bacteria, yeasts, and molds. This process either destroys the organism or controls its ability to reproduce. UVC germicidal light greatly reduces the growth and proliferation of mold and other bioaerosols (bacteria and viruses) on illuminated surfaces (particularly coil and drain pan). Surfaces must be cleaned prior to UVC light being installed. Available in volt and 0.0V-ph models. Air handlers have a factory provided knockout in the coil delta plate for mounting light within coil area. Shielding baffle is required when installing light above a non-uvc resistant component, such as a filter. Baffle must be ordered separately.
