STEAM DISTRIBUTOR NOZZLE (in duct location)
1. When installing the steam distribution nozzle of
the RESDELUX humidifier it must be located in
the supply duct at least 4 feet from any
obstructions such as bends, fans, filters, etc. to
prevent wetting (see figure #4).
2. The steam distribution nozzle can be mounted in
the bottom wall or on the vertical walls of the duct.
If the duct wall is more than 3/4" (20 mm) thick, the
nozzle will have to be mounted from the inside of
the duct. Remove internal insulation material if
necessary. (See Figure #5).
3. When the steam distribution nozzle is located
above the top surface of the humidifier: The
nozzle must be at least 1 ft (305 mm) above the
top surface of the humidifier. Locate the steam
hose so that it slopes at an angle of at least 20°
(Figure #6).
4. Steam distribution nozzle below top surface of
humidifier: The steam hose must first rise to the
minimum height of 1 ft (305 mm) above the top
surface of the humidifier and thereafter slope a
minimum 5
° in a uniform manner toward the
nozzle. A separate drain line must be provided for
condensate that collects at the steam distribution
nozzle (Figure #7).
