Simple Maintenance !
Disconnect the steam hose and remove
it from the cabinet. Tilt tank forward to
first stop.
Unlock the tank cap and set electrode
elements on top of the humidifier upside
down. (No need to disconnect the wiring)
The fast draining followed by the cool
cycle causes the electrode scale to fall off.
Adjust the flexible scale collection bag on the tank. Swing the tank completely down, all the
scale will fall into the collection bag.

UNIT MOUNTING
Unpack the unit and check for any damage.
A drilling template is supplied with the
packing : make sure to locate it before
throwing away the packing material.
Damage to packing and/or unit must be
reported immediately to the trucker. Save all
packing materials for their inspector.
Provide free space all around the unit, 3 to 3
1/2 ft. from the floor to the bottom of the
humidifier and at least 3 ft. above and 2 ft. on
the right hand side for allowing easy access for
maintenance.
Position the supplied drilling template against
the mounting wall and mark the mounting holes.
Drill the 7 (seven) holes and insert screws and
bolts appropriate for support (3 across top and
4 behind tank. ).
Install the 3 (three) upper screws allowing about
1/2 in. for hanging the cabinet. Hang the
cabinet and tighten the upper screws for
securing the mounting.
Loosen the release knob (1) a little, tip the
stainless steel tank (2) down until the steel
restraining cord is tight (3).
Disconnect the water level wires (4).

Let the tank gently tip all the way down.
Insert lower screws at 4, 5, 6 & 7 then tighten all
seven mounting screws.
Once all the screws are tightened, you can :
Tip the tank back to intermediate position and
attach the steel restraining cord.
Replace the tank cover and secure the 4

Water Connection
Unit mounting
A fresh cold water service should be used to supply the unit.
The water pressure should be between 15 and 90 psi and
should not exceed 100°F in temperature.
The water supply connection is through the bottom of the
unit. The humidifier is delivered with a 20 in. long water inlet
hose, with a 3/4 in. threaded female connector for the cold
water supply.
A manual shut-off valve and a check valve (not
included) should be located on the cold water service
connection to the unit.
Information about the water quality :
Chloride concentration < 75 mg/l
Phosphate concentration < 5 mg/l
Low concentration of CO2.
Organic elements in low concentration
Tap water or raw water
The water total desolved solids (TDS) may be up to 23
gr/gal (400 ppm). Check with the local water company. For
tank maintenance, refer to the maintenance page.
Softened water
The water TDS can be from 3.5 gr/gal (60 ppm) up.
Demineralized water
The RTH humidifier can run with demineralized water of
30 µS minimum (0.7 gr/gal or 12 ppm).

Steam Output
Installation
Use only high quality, low pressure steam
hose which is able to withstand steam
humidifier temperatures.
The steam hose alone may be used for
distances up to 6 ft. If the distance from the
humidifier to the duct is greater than 6ft.,
insulated rigid copper tube should be used,
with sections of steam hose for connectors.
All steam lines must be pitched so that
condensate which forms in the lines will be
drained back to the steam generator or to a
separator & trap in the steam line.
a. Provide vertical rise at least 20 in. before
bending the hose to horizontal.
b. The steam hose should be rigidly suported
to promote rapid draining.
c. Steam hose (radius of bend should be 30
in. Minimum.)
d. Duct work.
e. Obstacle.
f. A condensate separator and trap is needed
at this point to drain condensate.
g. 8 mm condensate hose. Fill the
condensate hose trap with water before
starting the humidifier to prevent steam
from escaping.
h. Humidifier height (see page 3. )
Number of steam outlets:
RTH 5 to 20 = 1 outlet 60mm ( 2.4 ‘’)
Reducer may be used (see page 9)
RTH 30 to 50 = 1 outlet 60mm (2.4’’)
RTH 60 to 100 = 2 outlets 60mm (2.4’’)
The RTH humidifier can work with duct
pressure up to 10’’ of water column.

RTH 5 to 100: 3 ft. of 40mm hose with 3
hose clamps provided.
This hose is designed for connecting the
humidifier to the drain. Periodic
replacement may be recommended.
If rigid piping is used, use copper or heat
resistant PVC material (212°F ).
The drain hose must be free from any
obstacle particularly when it comes to
connecting several units.
It is recommended the piping be offset
rom the underside of the unit as shown.
This will prevent any steam and/or
condensation from rising directly into the
cabinet.
A funnel can be used as well provided it is
offset from the underside of the humidifier
and that a drain trap is made as per the
diameter of the draining hose.
Important : keep a minimum pitch of 10°

Steam from the humidifier enters the duct
or an air handling unit via a steam
distribution pipe. For optimum absorption of
the steam, select the longest possible pipe.
Use multiple pipes if neccessary.

SteamPipePositioning
Installation
Install the distribution pipe on the duct with 4
scews.
A minimum distance of 12 in. between the
center of the steam distribution pipe and the
top of the duct should be alllowed. Where
the distribution pipe is installed at an angle
of between 30° and 45°, this may be
reduced to 6 in.
Where the application requires two
distribution pipes, the above-mentioned
recommendations should be observed
keeping a minimum space of 6 in. between
the pipes.
(d) is the minimum distance between the
distribution pipe and any obstacle within the
duct (see table on page 12).
Where a steam pipe is installed after a bend,
it should be positioned in the main air flow.
In vertical ducts where the air flow is upward
or downwards, the steam distribution pipe
should be mounted at an angle of 15° from
vertical

Absorption Distance
Installation
In order to determine the absorption
distance, this table can be used if you have
the following :
RH1 = relative humidity of the air before
humidification.
RH2 = relative humidity of the air after
humidification in %.
Delta RH = difference between RH1 &
RH2
How to use the table
Determine the difference between the
relative humidity (RH2) after the
humidification and the relative humidity
(RH1) before humidification. The
intersection between the delta RH value
and RH2 gives the evaporation distance in
inches.
.
The drawings show the distance (D) in
inches that should be allowed between the
distribution pipe and the first obstacle.
If the required distance is not available, it is
possible to install two pipes in parallel to give
better steam distribution.
A multi-steam distribution panel may be used
for short absorption distances. See catalog.
A high limit humidistat should be installed
to prevent excessive humidity levels in the
duct.
Note : The absorption distances given in
the table are for temperatures between
50°F and 78°F.
If accurate values cannot be determined or
estimated, a distance of 6.5 ft. should be
used as a safe minimum distance between
distribution pipes & any obstruction.
