Mount the Vapormist and SDU to wall studs using the template on
the box. Two lag bolts are provided with each unit.
Provide at least 6" (152 mm) clearance on each side of an SDU
when mounted remotely. For required SDU-E clearances see
Table22-1.
SDU-I is available for Vapormist humidifier models VM-2 through
VM-8, and all VM-10 models except those using 240V, three-phase
power with SSR control.
SDU-E is available for all Vapormist humidifiers except VM-2 and
models using 240V, 277V, and 480V three-phase power with the
SSR control option and drawing more than 21.7 amps.

SDU-I (Space Distribution Unit Internal Absorption)
disperses steam without a visible vapor trail. This
option is ideal for spaces where the presence
of vapor creates either a visual problem or a
condensation risk.
For larger capacities, choose the SDU-E (Space
Distribution Unit External Absorption).
Both SDU models offer extremely quiet, reliable
steam distribution.
Note: SDUs ship separate from the Vapormist.
