* Includes blower motor amps of lar gest fan coil used with heater.
{ Copper wire must be used. If other than uncoated (non---plated), 75_C ambient, copper wire (solid wire for 10 AWG and smaller, stranded wire for larger than 10 AWG) is used, consult applicable tables of
theNationalElectricCode(ANSI/NFPA70).
} Length shown is as measured 1 way along wire path between unit and service panel for a voltage drop not to exceed 2%.
** Field convertible to 3 phase.
{{ Field convertible to 1 phase, single or multiple supply circuit.
NOTES:
1. For fan coil sizes 018 ---037.
2. For fan coil sizes 042 ---061.
3. Single circuit application of F15 and F20 heaters requires single ---point wiring kit accessory.
