Installation
The steam from the cylinder enters the duct via a steam
distribution pipe. In order to obtain an optimum
performance of the humidifier, it is recommended that
these instructions be adhered to as far as possible.
Steam distribution pipe
selection
This table shows the number and the diameter of the
pipe(s) per unit.
For the optimum steam distribution, the longest pipe
should be prefered.
For duct of width inferior to 300 mm (12in), our B110 or
our special 6” steam pipes can be used.
For the CMC 1-2-3-4, install the pipes as indicated
below :
L= length 290 – 590 – 790 – 1000 – 1250 – 1500 mm
(11.4 – 23.23 – 31.10 – 39.37 – 49.21 – 59.05 in.)
S= end of pipe hole Ø 5 mm
R= 4 holes of Ø 5 mm (0.20 in.)
H1 = 140 mm mini. (5.50in.)
H2 = 300 mm mini. (12in.) (IMPERATIVE)

Steam pipe positioning
Installation
Positioning the recommended template
profile for cut-out in DUCT/AHU (at the end
of the brochure)
A minimum distance of 300mm (12in) between the
center of the steam distribution pipe and the top
of the duct should be allowed. Where the
distribution pipe is installed at an angle of
between 30°C and 45°C, this may be reducted
to 150mm (6in).
d: Minimum distance between the steam
distribution pipe and any obstacle in the duct
(filter, bend, constriction. etc) should as far as
possible, be no less than 2000 mm (6.50ft).
In the case where a steam pipe is installed after a
bend, it should be positioned in the main air flow.
In vertical ducts where air flow is upward or
downwards, the steam distribution pipe should be
mounted at an angle of 15°C from vertical.

Calculationoftheevaporationdistance
10
Installation
In order to determine the evaporation distance, the
enclosed calculation table can be used with :
RH1 = relative humidity of the air before humidification
RH2 = relative humidity of the air after humidification in
%
RH Max = maximum difference between RH1 & RH2
HOW TO USE THE CALCULATION
TABLE
Determine the difference between the relative humidity
after the humidification (RH2) and the relative humidity
(RH1) before humidification. The intersection between
the deducted maximum RH value and RH2 gives the
evaporation distance in meters (or in inches).
The table show the D distance (in meter/inches) that
should be between the steam pipe and the first obstacle
(s.a. pipe positioning drawings on the left hand side).
If the required distance cannot be obtained on site, it is
possible to install two pipes in parallel to have a better
steam distribution.
NOTA : the evaporation distance s shown in the
enclosed tables are for temperature between 10°C
(50°F) and 25°C (77°F) and for an air velocity of 2.5 m/s.
(8.20 ft/s).
If accurate values cannot be reached, a distance of 2 m.
(78 ft) should be considered as a minimum distance
between pipes & obstruction.

For sanitation : this sytem holds the water in the cylinder at a temperature of 65°C (150°F) to prevent
bacteria or mold from forming in the cylinder even if there is no humidity demand.
For fast boiling : When there is a demand for humidity, the water boils more quickly than with cold water.
This produces a faster response to the humidistat and more accurate control.
For freeze protection : Can prevent freeze-up if the humidifer is subject to cold environments. (Additional
protection required for the water feed and drain lines).
The optional temperature control system overrides the automatic factory pre-set draining time where the
cylinder(s) is (are) drained by the system after x hours of stop (s.a. page 3).
Note : the humidifier must be switched on for this system to operate.
