In vertical ducts where the air flow is upward or

downward, the steam distribution pipe(s) must

be tilted by 15° sideways

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.

2. Steam hose selection:

Ø 40 or 25

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

3.5 CONDENSATE DRAINING WITH SIPHON

The condensate hose must not be directly connected to the public sewerage network.

H min. (mm) = P (Pa)/10

with P = absolute pressure of the air handling unit or the ventilation duct
