IMPORTANT
BEFORE INSTALLING OR HANDLING THE HU315 HUMIDIFIER PLEASE FULLY READ AND FOLLOW
THE INSTRUCTIONS AND SAFETY STANDARDS DESCRIBED IN THIS MANUAL AND ILLUSTRATED ON
THE LABELS ATTACHED TO THE MACHINE.
This humidifier produces non-pressurized steam by means of electrodes immersed in the water contained in
the cylinder-boiler (hereafter called the cylinder). The electrodes pass current through the water, which also
provides resistance, heating the water into steam, which is used to humidify environments or industrial
processes, using special distributors.
The quality of the water used affects the process of evaporation, so the humidifier may be supplied with
untreated water, as long as this is drinkable and not softened or demineralized; the evaporated water is
automatically replaced using a fill valve. This humidifier has been designed exclusively to directly humidify
rooms or ducts, using a distribution system. The installation, use and maintenance operations must be carried
out according to the instructions contained in this manual and on the labels applied internally and externally.
The conditions of the environment and the power supply voltage must comply with the specified
values.
All other uses and modifications made to the humidifier that are not authorized by the manufacturer are
considered incorrect.
Liability for injury or damage caused by the incorrect use of the humidifier lies exclusively with the
user.
Please note that the humidifier contains powered electrical devices and hot surfaces.
All service and/or maintenance operations must be performed by specialist and qualified personnel
who are aware of the necessary precautions and are capable of performing the operations correctly.
Disconnect the humidifier from the main power supply before accessing any internal parts.
The humidifier must be installed in accordance with the local standards in force.
The local safety standards in force must be applied in all cases.
The humidifier is made up of metallic and plastic parts. All parts must be disposed of according to the
local standards on waste disposal.

•Check for shipping damage to cartons. Mark the shipping waybill accordingly
•Open cartons and check for any hidden damage. Mark the shipping waybill accordingly.
•Check packing slip to ensure all items have been received. Notify Quatro of any shortages or damaged
parts. You must notify Quatro within 5 working days of any shortages.

How The HU315 Works
HU315 is an electrode humidifier. It produces steam for humidification by passing electrode current through the
water in the steam generator cylinder between metal electrodes. There are no heater elements. Steam output
is directly proportional to the conductivity of the water, and the amount of electrode immersed in the water.
On a call for humidity, the HU315 controller will open the water fill valve (1) and allow water to enter the system.
A flow restrictor (2) prevents the unit from filling too quickly or with too much pressure. The water flows up the
fill tube (3) and into the fill cup (7), where it flows over the conductivity probes (6), which feed the water
conductivity back to the controller for analysis. Water then flows over the dam in the fill cup (7), which creates
a 1” air gap to prevent backflow of contaminated water into the feed lines, and through the fill tube (4) and into
the bottom of the steam cylinder (11).
As the water fills the cylinder, it will reach the electrodes (10) and current will begin to flow. As the water
continues to fill the cylinder, the current will increase, and this is monitored by an amperage transformer placed
on one of the power wires (9). When the desired current is reached, the fill valve will close (1) and the water
will then begin to warm and produce steam. If the water reaches the cylinder full probes (8) prior to reaching
the desired current level, the fill valve (1) will be closed to prevent overflow. If the current rises too much as the
water fills the cylinder, the drain valve or pump (13) will be activated to drain away some water and reduce the
current flow.
Periodically, based on the incoming water conductivity, the unit will drain some water to reduce the mineral
concentration. A strainer (12) in the cylinder helps to prevent mineral debris from jamming the drain valve (13).
If there is no water in the cylinder, there will be no current flow and no steam production. The electrodes do not
burn out, but they will eventually become comletely coated with mineral and the cylinder will then need to be
replaced or cleaned.

Installation
Positioning
The HU315 has been designed for wall mounting (although it can be placed on a stand) and, since it is an
atmospheric steam humidifier, should be placed close to the point where the steam will be used, to minimize
the steam hose length (and condensate). Certain clearances must be maintained around the unit:
Mounting
Removing the front cover
The front cover is secured by a capture screw located underneath the QUATRO
logo. Twist the QUATRO logo to reveal the screw, and use a phillips head
screwdriver to remove it. Then simply lift the front cover and pull out to remove
it. Return it in reverse order.
Fastening to the wall
Using the screws and anchors supplied, fasten the mounting bracket to the wall.
Be sure that the screws anchor firmly into studs or supports. Note the unit
installed weights from the Positioning section.
Once the mounting bracket is secured to the wall, hang the unit on the bracket. Fasten the remaining capture
screws through the bottom holes in the unit to secure it to the wall.
