AREA-TYPE APPLICATION USING SPACE DISTRIBUTION UNITS
SDU-I: Instant absorption, no visible vapor
The SDU-I (space distribution unit internal absorption) is available for models VM-2 through VM-10.
Room air is drawn into the unit by a fan, where it is humidified with steam generated by electric heating elements, and
then discharged back into the room with no visible vapor trail. Water vapor is instantly absorbed into the air making the
VAPORMIST with an internal absorption SDU (SDU-I) ideal for application in finished spaces.

If the SDU-E or SDU-I is immediately above the VAPORMIST, disconnect both hose clamps on the steam hose, grip
the hose and rotate it to break it loose from the tubing, and then slide the hose up onto the SDU steam tube until
sufficient clearance is provided to move the tank.
Field wiring is required to connect the SDU fan and air flow proving switch terminals to the respective VAPORMIST

electrical panel terminals. Refer to the external connections diagram in the package shipped with your unit.
