1. GENERAL DESCRIPTION
EVAPORATIVE HUMIDIFER OPERATING PRINCIPLES
FISAIR evaporative humidifiers are units designed to increase the water vapour content of the
treated air, by making use of the natural evaporation of water from its liquid phase. The air supply
being treated is passed through a cellular panel dampened using an irrigation system. This panel is
composed of undulating sheets of inorganic paper with stiffening and water absorbent additives.
The layout, as channels criss-crossing the panel provides a huge surface for water-air contact, which
maximises water evaporation, and reduces to a minimum resistance to the movement of the air
(pressure drop).
FISAIR evaporative humidifiers work in a similar way to natural processes in rivers, lakes, and seas.
The vapour added to the air is exclusively pure water vapour.
PROVISIONAL STORAGE
During storage, units must be kept dry and protected from the elements.
Warning: Avoid direct sunlight and sites in which temperatures can exceed 50ºC
Remark: Thermo-hygrometric conditions during storage:
Temperature: [-10… 50ºC]
Relative Humidity: [5…95%HR]
without condensation

1.1. Safety instructions
FISAIR disclaims any liability if not all the installation and operating instructions it has
provided are complied with; if the products have been modified or altered without the written
consent of FISAIR; or if the products have been subjected to improper use, mishandling,
alteration, improper maintenance or show signs of negligent use or being involved in an
accident. These situations could include an incorrect power connection, impacts with other
objects, removal or disarming of security fittings/measures, etc.
Please read these safety Remarks carefully and examine the equipment to become familiar with it
before installing, commissioning, or servicing.
The following symbols or messages may appear in this document or on the equipment. They warn
of potential hazards or provide information that may help you clarify or simplify a procedure.
Attention, Live Current
The presence of this symbol on a hazard or warning label indicates that
there is a risk of electrocution, which can lead to personal injury or life-
threatening conditions if the instructions are not followed.
Attention
The presence of this symbol on a hazard or warning label indicates that
there is a risk of electrocution, which can lead to personal injury or life-
threatening conditions if the instructions are not followed.
Installation of a residual current device in the power supply line
The installer must install a specific residual current device in the machine's electrical
power circuit.

2. RATING PLATE
The rating plate provides essential information about the technical features of the machine.
The EC MachinerySafety Regulation requires all machinery operated within the European Economic
Community to have a rating plate indicating its main features, the machine serial number and the
manufacturer's name inscribed in a durable manner.
According to article 2, section g of the Machinery Directive 2006/42/CE - RD 1644/2008, ‘partly
completed machinery’ means
“An assembly which is almost machinery, but which cannot in itself perform a specific application.
A drive system is partly completed machinery. Partly completed machinery is intended only to be
incorporated into or assembled with other machinery or other partly completed machinery or
equipment, thereby forming machinery to which this Directive applies”
•Model: description of the particular HEF3 device
•Serial No.: equipment serial number
•FISAIR devices it can be joined with
•Machine type: Machine or Partly completed machinery
•Designed in accordance with directive
•Made in Spain (EU): Place and date of manufacture
•QR code for technical assistance service and warranty activation
