INSTALLATION
3.1 PROCEDURE
•Remove the device from its original packaging and check its condition. If there is any defect in the
appliance, make a detailed complaint to the carrier within 3 days.
•Remove the steam cylinder and place it carefully on the floor.
Step 1
•Take the drilling template provided, and place it in the desired
location, taking into account the dimensions.
•Mark and drill the mounting locations:
KIT MC 5 to 30: mark the 8 holes.
KIT MC 40 to 60: mark the first 8 holes. Mark the corners
of the template and then place the template on the right
side. Align the corners and mark the last 8 holes (16
markings in total).
•Then drill a hole of Ø3 or 4 mm according to the diameter of
the fixing screws you want to use.
Step 2
•Take the upper support. Screw in the first screw (for
example), make sure that the support is level (use a spirit
level) and then screw in the 4 screws until they are locked.
•Attention: for the KIT MC 40 to 60, do not forget to fix the 2
high supports (8 fixing screws in total).
Step 3
•Take the lower support. Screw in the screws and check the
vertical alignment and your dimension H (see dimensions on
pages n°9 & 10 & 11) and then screw in the 4 screws until they
are locked.
•Caution: for the KIT MC 40 to 60, do not forget to fix the 2
lower supports (8 fixing screws in total).

drain valve.
▪For the KIT MC 40 to 60, proceed in the same way for
the 2nd cylinder.
Step 5
▪Properly press the base of the cylinder into the body of
the drain valve.
▪Check that the spring is correctly positioned around the
notches located on the cylinder.
▪For KIT MC 40 to 60, proceed in the same way for the
2nd cylinder.
The installation of your device is now complete. Please proceed to the different phases of
connections.

3.2 WATER SUPPLY
3.2.1 Recommendation
Our device is designed to be used with any following water type:
✓drinking water (according to Directive 98/83/EEC, TH (French grade)
between 0°fH and 40°fH and conductivity between 250 µS/cm and 1000
μS/cm)
✓softened water,
✓demineralized water, reverse osmosis water: use possible under
conditions. Please contact our services
The demineralized water is corrosive; use appropriate piping material: stainless
steel, PVC.
Softened water: Its use is not necessary, but possible. TH should be between 0° fH and 2° fH.
Water analysis is recommended to determine the level of sodium chloride.
Do not hesitate to contact our services for support.
3.2.2 Recommandations on connection
Network water pressure: The pressure must be stable and between 2 bar and 8 bar MAX. in case the
water pressure exceeds 8 bar, a water regulator calve must be used.
Network water temperature: < 40 °C.
Please note that the water supply is connected at the lower part of the unit.
For easy maintenance, the water inlet valve is equipped with a filter strainer which should be checked
periodically. It is essential to install an isolation valve near the humidifier to facilitate maintenance.
OVERFLOW RISKS: it is recommended to install a collecting water tank under the
humidifiers to prevent overflow. This is essential if the unit is installed in false
ceilings or above important rooms (example: museum room, showroom, laboratory
etc.). Make sure the container is connected to the wastewater system.
An excess of sodium chloride may generate foam which disturbs the correct running
of the humidifier. It is mandatory to use a duplex softener.
Max. chloride content: 80 mg/l

3.3 DISPERSION TUBE POSITIONING
Steam dispersion tubes:
the steam from the humidifier is injected in a duct or an air handling unit via a steam dispersion tube.
To obtain the best performance of the humidifier, select the longest pipe.
Absorption distance "D"
Make sure that the absorption distance is met in order to let the air absorb the steam dispersed by the
tubes. In this absorption distance, the steam is still visible in the air stream in the form of fog. If any
furniture is placed in this area, condensate may occur. For this reason, it is imperative to consider this
absorption distance when placing the humidifiers.
How to calculate absorption distance « D »
In order to determine the absorption distance, the attached calculation table can be used:
▪RH1 = relative humidity of air before humidification in %.
▪RH2 = relative humidity of air after humidification in %.
▪D mini = minimum absorption distance in meters (m).

•A high limit humidistat must be installed in the duct to stop the humidifier in case the level of
humidity exceeds the preset value.
•If the recommended distances cannot be met, please contact Devatec or their authorized agent
for an alternative solution.
•Make sure the distances are met, if this is not possible, please contact your Devatec agent.

Make sure that spaces and distances are respected. If you have any doubts about the calculation,
please contact us.
H1 = 110 mm = Minimum height between the duct floor and the axle of the steam pipe.
H2 = 140 mm minimum for a standard mounting / 110 mm minimum for a stair mounting.
H3 = 160 mm = Minimum height between the axle of the dispersion tube and the top of the duct wall.
The H3 distance can be 80 mm at the shortest if the steam pipe is installed at a 30° angle.
In the case of a stair mounting, minimum distance between tubes = 100 mm.

3.4 STEAM OUTLET
1. Preferably use a flexible steam hose that is resistant to a temperature of 100°C.
NB: when new hoses are installed, a smell of burnt plastic may be smelt during the first running of the
steam humidifier. This is normal and will eventually diminish.

3. KIT MC humidifiers can operate with a pressure (P) higher than the atmospheric pressure in the
ducts, but under the following conditions:
•If P is less than 150 mm WC or 1470 Pa.
•If P is greater than 150 mm WC (1470 Pa), options are available up to 700 mm WC (6860 Pa).
4. For the installation of the steam hose, depending on your environment, please respect the
recommendations below and use the appropriate tangential hose clamps.
•Flexible steam hose length 3 m max.
•Stainless steel or copper pipe with a slightly larger diameter, grounded. Use a flexible steam hose
cuff to connect the humidifier to the steam distribution pipe. The length of the pipe must be
thermally insulated and should not exceed 6 m.
Always have a slope in the same direction (up or down); the steam hose must
be free of kinks and sags to allow for gravity drainage of condensate.
Make sure that the steam hose is not leaky. Failure to follow these
instructions can lead to serious malfunctions.
Radius of the diameter steam pipe:
•Ø 25 - 250mm minimum
•Ø 40 - 400mm minimum
