Air handler units are approved for installation in manufactured housing and mobile homes. ISO 900 Registered Manufacturing Quality System. APPLICATIONS. to ton nominal sizes. Multi-position (upflow, downflow or horizontal) applications. Applicable to expansion valve systems in R-0A cooling applications and check and expansion valve systems in R-0A heat pump applications. 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. A I D 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. CXM / Page

4 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. reaker Models The following heaters are equipped with circuit breakers for overload and short circuit protection: EC9-C, -C, -C, -8C, -9C, -0C, -.C, -C, -0C, -C and -0C (08/0V-ph) EC9-C, -0C and -C (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. Consult local electrical code in your area. NOTE - 0V- phase air handlers can be used in 7V applications. 7V electric heaters are shipped with a 7V to 0V step-down transformer. I Optional Accessories reaker Cover Kit Flexible plastic cover protects circuit breaker. Recommended in areas with high humidity or unconditioned areas to prevent nuisance tripping. Single-Point Power Source Control ox Control ox may be used with optional electric heat when single power supply is connected to multi-circuit electric heat. Field installs external to the unit cabinet on either side or top. Constructed of heavy gauge steel, baked enamel finish, prepunched mounting holes, electrical inlet knockouts, and terminal strip.
