WATER CONTROL
The water contained in the cylinder must be controlled, in order for the humidifier to function properly. The fill and drain
rates must be maintained. Filling too quickly can cause over-amping and automatic shutdown, circuit breaker tripping or
blown fuses. Filling too slowly can cause insufficient steam output or insufficient humidity levels. Water supply pressure
should be between 30 and 80 psig, ideally 55 to 60 psig. Draining too quickly can cause dangerous arcing and elec-
trode corrosion. Draining too slowly can cause over-concentration and malfunction due to foaming. These are just some
examples of what can go wrong if the fill and drain rates are not controlled and maintained.
