Engineering Specs
Contractor shall supply and install KF / KFS ECO2S Series electric furnaces manufactured by King Electrical Mfg. Company. Furnaces shall be of the wattage and voltage as indicated on the plans.
Transformer: Each furnace is equipped with a heavy duty low voltage (40 VA) transformer for the thermostat control circuit.
Time Delay Sequencer: Actuates heating element banks to minimize electrical surges in compliance with E.E.I. and N.E.M.A. standards.
Heating Elements: Quick heating, long life Ni-Chrome elements are sized to provide proper watt density for maximum heat dissipation.
Terminal Block: For field wiring (optional special order) KFSTB Single Strike Connection. Takes multiple circuits into a single feed.
Air Filter: Convenient access for replacement of standard 16” x 20” x 1” filter. Do not use pleated filters.
Motor: Energy Saving, Long life, thermally protected, permanently lubricated, direct drive ECM motor—no belts to adjust or slip. This low noise, 3 speed motor is designed for use with air conditioning capability as well as heating. Very quiet operating. 60 second fan delay.
Overcurrent Protection: 208 and 240 volt KF / KFS models have 60 amp circuit breakers. 208 and 240 volt KF models have terminal blocks.
Limit Control: Integral automatic high temperature limit control in each heating element bank prevents the delivery of air at unsafe temperatures. 20-35 KW models use a manual reset limit control to completely shut the furnace off should an unsafe temperature occur. Summer fan only operation. Fan can be run independently from heating. Mobile Home approved.
Unique Fan Orifice: Louver directs air over all heating elements and side walls evenly ensuring longer life performance.
Low Voltage Terminal Block: 24 Volt control screw terminals.
Approvals: cULus (E48864) USA and Canada
