See bulletins in section Air Conditioners for cooling capacities. See bulletins in section Heat Pump Outdoor Units for cooling and heating capacities. Optional field installed electric heaters available in several sizes for additive heating capacity. AB I D B C REFRIGERANT SYSTEM Copper Tube/Enhanced Fin Indoor Coil Lennox designed and fabricated twin coils. Assembled in A configuration. Provides extra large surface and contact area, excellent heat transfer and low air resistance for maximum efficiency. Precise circuiting for uniform refrigerant distribution. Precisely spaced ripple-edged aluminum fins fitted to durable seamless copper tubes. Fins are strengthened to resist bending and are equipped with collars that grip tubing for maximum contact area. Lanced fins provide maximum exposure of fin surface to air stream. Long life copper tubing is easy to service. Rifled tubing provides superior heat transfer. Flared shoulder tubing joints and silver soldering provide tight, leakproof joints. Coil thoroughly factory tested under high pressure to insure leakproof construction. CBXM / Page

H FEATURES OPTIONAL ELECTRIC HEAT Field install internal to unit cabinet. Available in several voltages and kw sizes. See Electric Heat tables. Helix wound nichrome heating elements exposed directly in air stream resulting in instant heat transfer, low element temperatures and long service life. Each element equipped with accurately located limit control with fixed temperature off setting and automatic reset. Supplemental thermal cutoff limit control, provides positive protection in case of excessive temperatures. Thermal sequencer relay brings elements on and off line, in sequence and equal increments, with time delay between each. Initiates and terminates blower operation. Heating control relay(s) furnished as standard. Control box and access cover constructed of heavy gauge galvanized steel. Factory assembled with controls installed and wired. Electric heat low voltage controls plug-in to air handler. Breaker Models The following heaters are equipped with circuit breakers for overload and short circuit protection: ECB9-CB, -CB, -CB, -8CB, -9CB, -0CB, -.CB, -CB, -0CB, -CB and -0CB (08/0V-ph) ECB9-CB, -0CB and -CB (08/0V-ph) Factory wired and mounted on electric heat unit. Current sensitive and temperature actuated. Manual reset. breakers qualify as disconnect means at unit in many areas, eliminate the need for field provided disconnect.
