14. Installing the Steam Diffuser and the Steam Hose
14.1 Proper installation of the diffuser and steam hose is critical for the trouble-free operation of the
humidifi er. Please fi nd an accessible location on the duct and make sure you have a minimum length of
35” of straight duct downstream (without elbows or other obstructions on which the steam could condensate),
to allow the steam to disperse easily into the airfl ow. Once a suitable location has been found make a 1 1/8”
middle insertion hole in the warm air duct for the steam diffuser. For a horizontal duct, make the 1 1/8” hole in
the lower third of the duct height. Please see Fig. 14a. For a vertical duct, make the 1 1/8” hole in the middle of
the duct. Please see Fig. 14b.
Note: For High Velocity systems, the diffuser should be installed in the RETURN and not the warm air duct.
Warning : Before installing anything on a duct, always check that you are not about to cut or drill into an air
conditioning coil or electrical accessories.
14.2 Insert diffuser in duct and align arrow to point up. Fasten the steam diffuser to the duct using four #8 x
1/2” screws provided in Kit #10S. Make sure the holes on the steam diffuser, where the steam exits from, are
pointing up. Please see Fig. 14c.
Note: Acu-15 models are supplied with two diffusers, hoses and clamps, if there are dual ducts install one
diffuser in each duct with equal lenth of hose on each. When installing in the same duct keep a distance of 6”
to 12” between diffusers. Please see Fig. 14d.
