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.
