STEAM HOSE INSTALLATION
1. The length of the steam hose must not exceed 4’
(1.2m).
2. It must not be restricted in any way (i.e. - a kink
resulting from a short radius bend).
3. Avoid condensate traps in the hose, see Figure
#8.
4. Use wall clips (p/n 158-5001) to support the
steam and condensate hoses and maintain 1”
clearance from the wall. The connection can also
be made with ¾” copper pipe with 1” thermal
insulation rated for 215°F (101°C).
CONDENSATE HOSE (supplied)
Under normal circumstances, when the steam
distribution nozzle is above the top surface of the
humidifier, the condensate hose is routed back to the
top of the humidifier and fed through the opening
provided to the fill cup. Cut the ends diagonally and
simply insert ½" in the appropriate hole in the top of
the humidifier. Install a 3/8” copper tubing trap at the
lowest point in the condensate system. Connect to the
hose with a clamp Figure #6.
BLOWER PACK CONNECTION
The RESDELUX humidifier can be purchased with
an optional blower pack for direct room humidification.
The blower pack is field installed on the RESDELUX
humidifier cabinet or located remote from the
RESDELUX humidifier.
The blower pack is powered directly from the
RESDELUX control board. It cannot be powered
separately.
On a call for humidity, blower fans are powered
and remain powered for about two minutes after steam
production is interrupted.
Cabinet Mounting of the Blower Pack
The RESDELUX blower pack comes with a basic
hardware kit. The kit contains all the hardware
required to cabinet mount the blower pack.
NOTE: Mounting of the blower pack must be
performed before the RESDELUX humidifier is
installed and wired.
1. Remove the RESDELUX humidifier and blower
pack from their shipping boxes.
2. Place the RESDELUX humidifier upright on a flat
surface.
3. Remove the 7/8” knockout on the top of the
RESDELUX humidifier. There are two
knockouts, select the one closest to the large
opening.
