Notes:
* Measurement taken 6.5' (2 m) in front of SDU cabinet.
** For visible vapor to be absorbed completely within the SDU-I unit before being
discharged as humidified air, room air must be 45% RH or less. Trying to maintain
greater than 45% RH will cause visible vapor and potential for moisture collection
on the discharge grille.
Notes about SDUs (Space Distribution
Units):
• The SDU-I is available for models VM-2
through VM-8, and all VM-10 models
except those using 240V, three-phase
power with SSR control.
• The SDU-E is available for all Vapormist
models except those models using
240V/480V/600V/three-phase power with
the SSR control option and drawing more
than 21.7 amps.
• SDUs ship separately from the Vapormist.

Notes:
* On 208V/240V/single-phase/three-wire and on 208V/three-phase/four-wire supplies, the neutral line provides a separate 120V circuit for the SDU fan unit.
** For wire sizing, the highest leg draw is shown due to current imbalance.
† Add the following to Vapormist weights if using an SDU option (these weights are for additional control components housed within the Vapormist cabinet):
– SDU-I: 12 lbs (5.5 kg)
– SDU-E: 9 lbs (4 kg)
See the SDU weights Table 11-2 below for SDU weights (shipped separately).
‡ Add the following if using the SSR option:
– For single-phase or three-phase models drawing less than 21.7 amps, add 2 lbs (1 kg)
– For three-phase models drawing more than 21.7 amps, add 4 lbs (2 kg)
All Vapormists operate at 50/60 Hz.
