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. 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. 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 Breaker Cover Kit Flexible plastic cover protects circuit breaker. Recommended in areas with high humidity or unconditioned areas to prevent nuisance tripping.
