Herrmidifier Co 6000 - Manual (Page 6)

Engineering and Application
The Herrmidifier 6000 Series Steam Humidifiers can be
applied in a variety of applications. The simplest
application is to utilize the model with the built-in blower
package (6000-1,2). The steam generated by the unit is
distributed into the conditioned space by the built-in
blower package (Figure 1).
Alternatively, steam generated by the "6000" unit can be
discharged directly into the system ductwork (6000-3,4).
In this application, a steam pipe is preferably installed in
the system ductwork at least five (5) feet downstream of
the supply air blower. There should be no obstructions
within the first five- (5) feet downstream of the steam
distributor as shown in Figure 2. An air-proving switch
and high limit humidistat are provided for better system
control in ducted applications. If the heating system
operates for short periods at a time and the desired
relative humidity level is not achieved, the humidifier can
be wired to turn on the blower when there is a call for
humidity. In this case an air-proving switch will not be
necessary, but the high limit humidistat should still be
utilized.
NOTE
The steam distributor pipe is inherently sloped to
return the condensate to the humidifier.
The steam piping from the humidifier to the steam
distributor should have an 8% slope (1” per foot) up
to the steam distributor. Steam hose may be used up
to a maximum of 20’ between the unit and the steam
distributor. The hose provided with the unit is 10’
long. There can be no sags in the steam hose, as
this will create a trap and will produce back pressure
in the steam cylinder and may blow condensate in
the duct.
