*
If using an optional SDU or Area-type fan unit for dispersion, run a neutral line with 208V/240V/single-phase and 208V/three-phase power
supply lines to provide a 120V circuit for the fan. With all other power supply voltages (other than 120V), provide a separate 120V circuit for
the fan, or order from DriSteem a transformer installed in the control cabinet.
** Heater stage identifi es the number of contactors.
*** Three-phase power supply connection. All heater loads are wired Delta.
†
Total humidifi er load = load to meet design cond load to compensate for steam loss from the dispersion assembly and interconnecting
piping. If total humidifi er load is more than the humidifi er's maximum capacity, design conditions will not be met. For steam loss data see the
DriSteem Design Guide available for downloading and printing at www.dristeem.com
