†Field convertible to 1 phase, single or multiple supply circuit.

‡ Field convertible to 3 phase.

** Includes blower motor amps of largest 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 the National Electric Code (ANSI/NFPA 70).

‡‡Length shown is as measured 1 way along wire path between unit and service panel for a voltage drop not to exceed 2%.

***Heaters are Intelligent Heat capable when used with the FK, FV fan coils and corporate 2-speed programmable thermostat (TSTATBBP2S01-A), or Thermidistat™ Control (TSTATBBPRH01-B). NOTES: 1. For fan coil sizes 018-036.

2.For fan coil sizes 042-060 and all FK4D, FV4B sizes.

3.Single circuit application of F15 and F20 heaters requires single-point wiring kit accessory
