• All RTS humidifier models operate at 50/60 Hz.
• For wire sizing, the highest leg draw is shown due to current imbalance.
• See Table 66-1 for heaters.
• Maximum amps is determined based on the heaters used by each model. Some voltage/kW combinations show higher amperage values than
what the unit capacity will allow.
