Electrical Characteristics
Allowable voltage range, VDC 47-51
Insulation resistance, MOhms 100 or more (excluding solid-state components).
Dielectric voltage withstand Operational when 1500 VAC is applied for 1 minute (excluding solid-state
Operating conditions
Ambient working conditions 34 °F to 122 °F; 90%RH or less.
Water supply quality DI or RO water. Water conductance <5 microsiemens purity.
Water supply pressure, psi 30 to 75
Water supply temperature, °F 40 to 104
These parts must be provided by the user:
DI or RO supply water, Water supply valve, Water supply tubing (1/4” stainless steel or poly tubing rated for DI
water), power supply wiring and control wiring to the control box.
1. Calcium, magnesium or other agents that may be contained in the supply water are
atomized into the air together with the mist and may form white powders after the water
has evaporated. To avoid this, always use DI or RO supply water.
2. The nebulizing capacity of the transducer in the ultrasonic nebulizer unit decreases
gradually with use. It should usually be exchanged after about 10,000 to 15,000 hours of
operation, (depending on water quality and suitable voltage), although the unit may
continue to run as long as its effective capacity meets the particular requirements.
3. To ensure full warranty coverage, the input voltage to the humidifier must not exceed
51VDC. If the input voltage exceeds 51VDC, damage to the transducers and print plates
will result.
