1 - TECHNICAL RECOMMENDATIONS/WARRANTY
For all technical recommendations relating to the humidier, please see paragraphs 1-GENERAL, 2-SAFETY GUIDELINES,
3-REGULATIONS of Instruction Manual FR 7486825 for the Unit, supplied with the product.
Regarding the warranty, please see paragraph 1-GENERAL of Instruction Manual FR 7486825 for the Unit, supplied with the product.
CAUTION : All specic recommendations relating to the humidier are described below in paragraphs 3-DESCRIPTION,
4-TECHNICAL CHARACTERISTICS and 5-INSTALLATION/START-UP//MAINTENANCE.
CAUTION :
RESPONSIBILITIES
All personnel operating a humidier are responsible for:
-their personal safety, the safety of other people and the prevention of damage to the humidier
-the correct operation of the humidier
-electrical wiring must be installed in accordance with national standards, by qualied personnel..
These instructions explain how the humidier must be used.
These instructions are recommendations only, and do not replace the responsibilities set out above.
2 - OPERATING PRINCIPLE
Increasing the relative humidity by passing air through a matrix moistened with water is a simple, safe method of humidication, with
the benet of the adiabatic cooling generated and low operating costs.

The dry air passes through an absorbent cellulose bre or breglass matrix and collects the water vapour located on the moist surface.
The water is distributed from the top of the matrix by a solid stainless steel nozzle bar and distribution cassettes located at the top of
each vertical row of matrices ensure even humidication.

WARNING : The humidier is pre-wired when option 15 (AHU control) has been selected. Otherwise, the installer is responsible

3.2 - General recommendations
■Recommendations for optimised operation
The air passing through the module must be ltered at least to ltration standards F7 and ePM1 50% in order to prevent fouling of the
humidier cassettes. Finer ltration may also be necessary in hospitals, food processing and electronics settings. We recommend that
a water lter be installed on the supply.
If the supply water for the humidier has a calcium content above the recommended level (see "drinking water network analytical
parameters" after component 9), we recommend that the water be demineralised.
When the humidier is the last component of the Unit, we recommend that an expansion valve be positioned 1,000 mm downstream
of the humidier.
■Recommendations for use in accordance with hygiene standard VDI6022
This adiabatic evaporative humidier option is certied in accordance with VDI6022 subject to certain restrictions and operating
conditions:
-The standard relates to RW and DW humidiers equipped with an inorganic breglass medium
-DW humidiers must be equipped with 3-way valves
-RW humidiers must be equipped with CCB control boxes (the option includes the supply and drainage solenoid valves)
-These humidiers and their control boxes are designed so that they ensure complete drainage of the water from the tank and the
supply and drainage pipes during one-off or permanent shutdowns of the humidication system for more than 48 hrs.
-Whenever the humidier is shut down, the Unit controller must ensure that the humidier media are dried completely.
-The water supply pipes must be equipped with a device preventing any water from returning to the drinking water column.

■Indicative water consumption (depending on air conditions)
• recirculated water (RW) dehumidier:
Evaporated water ow rate in l/hr with pump (pH neutral, medium TH), T°=30°C and 10% RH
Type of humidier medium Flow rate in l/hour for 1,000 m3/hr of air
Fibreglass or cellulose bre - 65% efcient 5.6 l/hr
Fibreglass or cellulose bre - 85% efcient 7.1 l/hr
Example: AHU025- humidier 85% -8,000 m3 /hr =8 x 7.1 = 56.8 l/hr
Deconcentration ow rate (to limit mineral salt concentration in the tank):
Deconcentration ow rate = see the "technical recommendations" paragraph in "mineral salt deconcentration by a. Deconcentration
manifold"
Water consumption = evaporation ow rate + deconcentration ow rate
• direct water (DW) humidier:
Evaporation module with continuous water supply.

4.2 - Characteristics of the components
1. Water supply connection
Technical characteristics
1/2" BSP-M stainless steel pipe
Technical recommendations
Connect the mains water to the 1/2” BSP male connector oat valve with a shut-off valve. Apply sealant
before connecting. Ensure that the supply pipes can be uncoupled from the humidier downstream of the
shut-off valve, so that the humidier and the front panel can be removed completely in the event of heavy
maintenance.
2. Float ll valve
Technical characteristics
304 stainless steel
Technical recommendations
The oat valve can be adjusted by 25 mm vertically using a 20 mm spanner, to adjust the tank water levels
(image 1). When the tank is full, the water level must be 3 cm below the overow. During operation, the
level must never drop below the foot of the pump, as this can damage the pump irrevocably (image 2).
The water level in the tank can also be adjusted by altering the rotation (max. 110°) of the oat, using a 10
mm spanner (image 3).

3. High and low water level sensor
Technical characteristics
304 stainless steel
Technical recommendations
CAUTION: Remove the protective net from the oat before system start-up.
Low level: This connection is mandatory to protect the operation of the recirculation pump, as it activates
and deactivates the pump when it detects a minimum water level in the tank (if the humidier control option
has been selected connector J17 on the SEF-028 card in the Control Box - NO contact).
High level: The maximum level is used as a safety system if the water supply oat valve fails. It must not be
used to control the water supply. If the equipment has a supply solenoid valve, connect it here so that it is
shut off by the safety system (if the humidier control option has been selected connector J16 on the
SEF-028 card in the control box - NC contact).

4. Recirculation pump
Technical characteristics
Stainless steep pump body + plastic accessories
Rated power 60 W (0.13 A) or 125 W (0.36 A) depending on size, medium and efciency.
400 V/3~+PE/50 Hz connection
Connection box: PG9 packing box, max. cable Ø = 8 mm. IP 54
Technical recommendations
Connect the power supply line to the terminal connection box on the water irrigation pump.
Unless the control option has been selected (humidier only or AHU), the protection and power supply of
the pump must be determined by the system project designer. When option 12 - humidier control - has not
been selected, we recommend a thermal-magnetic circuit breaker with a rated current of:
0.1…0.16 A for the 60 W pump or 0.25…0.4 A for the 125 W pump.
