IMPORTANT: RISK OF MALFUNCTION. THE STATIC PRESSURE AT THE DISPERSION TUBE
LOCATION SHOULD NOT BE GREATER THAN 0.5” (125 Pa) DURING OPERATION. FAILURE TO
DO SO WILL VOID THE WARRANTY.
For a higher static pressure, use the Neptronic
SK300 commercial series humidifier.

Recommendations for the location of the steam dispersion tube
IMPORTANT:
Risk of malfunction.
1. Do not split the steam output piping to
supply more than one duct.
2. Do not reduce the diameter of the steam
hose or piping. Hose and piping diameter
must be the same as the diameter of the
humidifier steam outlet.
Provide a
minimum of 18” (460mm) of straight
duct
,
without
obstructions
or
elbows,
downstream of the dispersion tube.
Select an accessible location in the supply air
duct.
For the
SKR-14
&
25
, use a template and drill a
1-1/2" (38mm) hole in the supply air duct for the
installation of the of 7/8" diameter dispersion
tube.
For the
SKR-30
&
40
, use a template and drill a
2" (51mm) hole of in the supply air duct for the
installation of the of 1-3/8" diameter dispersion
tube.
Secure the dispersion tube bracket to the duct
using sheet metal screws (not included).
In a vertical duct installation the holes of the
dispersion pipe should be aligned with the air
flow (see fig. 8d & 8e below).
