* 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-I shipping weight is 68 lbs [31 kg])
– SDU-E: 9 lbs (4 kg) (SDU-E shipping weight is 61 lbs [28 kg])
‡ 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 Vapormist models operate at 50/60 Hz.
