Low vertical units are only available with electric heat in combination with the two-row cooling coil.

Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations for Fan-Coils with Single Phase Electric Heat

Heater amps = (heater kW x 1000)/heater voltage

Note: Use 120V heater voltage for 115V units. Use 240V heater voltage for 230V units.

MCA = 1.25 x (heater amps + all motor FLAs)

MFS or HACR type circuit breaker = (2.25 x largest motor FLA) + second motor FLA + heater amps (if applicable)

HACR (heating, air-conditioning and refrigeration) type circuit breakers are required in the branch circuit wiring for all fan-coils with electric heat.

Select a standard fuse size or HACR type circuit breaker equal to the MCA. Use the next larger standard size if the MCA does not equal a standard size.

Standard fuse sizes are: 15, 20, 25, 30, 35, 40, 45, 50, 60 amps

Fan-coil electric heat MBh = (heater kW) (3.413)
