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.
