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. ELMC 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 – 250 mm minimum
• Ø 40 – 400 mm minimum
