Quatro HU313 Manual

The HU313 humidifier is what is called an "electrode" humidifier. This means that instead of heating
elements, metal electrodes are immersed in water contained in a plastic cylinder. When steam is required
for humidification, electric current flows through the water between the electrodes. The minerals in the
water provide both the conductance and resistance for electric flow, thus producing steam. This technology
is VERY advanced over electric element type humidifiers and has the following advantages:
Efficiency: Operates at 94% energy efficiency over 95% of the life of the cylinder as compared to 90%
reducing linearly to less than 60% over the life of an element type humidifier.
Reduced maintenance: Instead of scraping out a metal pan and electric element, the plastic cylinder is
simply replaced with a completely fresh one.
Response time: is sometimes twice as fast as element type humidifiers.
Failsafe: If the unit runs dry, power flow is automatically stopped where in element type units, the
elements burn out. On a call for humidity, the humidifier controller (R) closes the power contactor, putting
power to the electrodes in the steam cylinder (B), and opens the fill valve (C) to allow water to flow into
the water fill tank (V). In, or in line with, this tank is a conductimeter (D) which reads the water quality.
As the water level rises in the cylinder, it begins to cover the electrodes and current begins to flow,
warming the water and producing steam.
When the desired amperage is reached (which is directly proportional to steam output), or if the water
reaches the high level electrodes (E), the water fill will stop. As water is boiled off, minerals will build up
in the cylinder and periodically the controller will open the drain valve or pump (S or P) and remove some
of the mineral laden water.Eventually the cylinder electrodes are used up and the electronic controller
signals time to change the cylinder.
Your HU-313 steam humidifier will consist of:
Steam humidifier unit
Steam distributor Unit (blower)
Mounting bracket, mounting hardware and water fill quick connect fitting
Humidity sensors
IMPORTANT: BEFORE beginning installation:
Check for shipping damage to cartons. Mark the shipping waybill accordingly.
Open cartons and check for any hidden damage. Markthe shipping waybill accordingly.
Check packing slip to insure all items have been received.
Notify Quatro Air Technologies immediately of any shortages ordamaged parts.
You must notify Quatro Air Technologies within 5 working days of any shortages.
