SIMPLIFIED INSTALLATION INSTRUCTIONS
DETAILED INSTALLATION INSTRUCTIONS
1. Insulate the water reservoir. See figure 3.
2. Select the mounting location on the duct and tape
on the mounting template.
3. Drill the (8) 1/8" mountings holes.
4. Cut out the humidifier opening in the duct.
5. Insert the humidifier into the opening and screw in
place.
6. Flush and connect the water line.
7. Connect the drain line.
8. Make 24 VAC electrical connections to achieve fan
operation and interlock circuit.
9. Install and connect the humidistat.
10. Plug power cord into a grounded dedicated 120 VAC, 20
amp outlet for S2000 (240 VAC, 15 amp for S2020).

With insulation foil side down, remove adhesive backing.
Align humidifier so that front side of unit meets long edge of
insulation. Fold insulation up onto sides of humidifier and
press firmly. Apply 5 continuous strips from the tape
provided to seal the foil as shown. The tape will prevent the
sharp duct edges from damaging the foil. Use additional foil
tape to repair damage to the foil.
The Insulation MUST be
applied to the tank regardless of the mounting location.
DO NOT INSTALL this unit in an attic period. Do Not
Install this unit in any area that may fall below 35
degrees F. Doing so will void your warranty!
The steam
humidifier can be installed in either the warm air supply or the
cold air return ducts; however the
preferred
location would be
in the warm air supply duct of the system. This humidifier does
not require warm air to evaporate the water in order to provide
humidity, but it will operate more efficiently in the warm air duct
and condensation is less likely to occur on the surrounding cold
surfaces. Efficiency is lost in a return air duct location.
When selecting a location on the duct, be certain that there is
enough room in the duct for the water reservoir. There should be
at least five (5) inches above the reservoir and the reservoir
should not occupy more than about 25 percent of the duct space.
If this criteria can not be met, you should install the unit under
the duct by means of the tank flange.
See page 6.
If a suitable means of gravity draining the unit is not available
or cannot be provided, the unit will work with the drain valve
electrically disconnected. Call the Technical Support Hotline
for Instructions.
It is highly recommended but not required that the
use of Fiberglass duct-board with this product
includes an anti-microbial treatment.
Providing Adequate Structural Support for this unit is the
responsibility of the Installer. It is recommended to
reinforce the cut openings with folded lengths of sheet-
metal to provide rigidity to the duct opening. Now the
screws must pass through 3 layers of metal when inserted.
DO NOT install this unit into fiberglass duct without
adequate structural support!
Both models weigh
approximately 9 lbs. empty and 15lbs. full of water.
Two mounting templates are provided. Choose the correct
template for your mounting method. Tape the mounting
template to the duct. The template must be leveled using the
top of the cutout on the template. The template should be
located so that the bottom of the reservoir cut-out is flush with
the inside of the bottom of the duct for horizontal duct. Since
most ducts are insulated this additional space, about one (1)
inch, must be accounted for when determining the location
for the bottom of the reservoir cut-out. If you are mounting it
under the duct, make sure the duct is level.
Use an electric drill, with grounded power cord, to drill eight
(8) mounting holes, 1/8" diameter, in the duct. These can be
drilled through the template at the locations indicated on the
template.
A saber saw or tin snips can be used to cut out the water
reservoir opening.
Insert and/or mount the Humidifier and secure it to the duct
with the provided screws.
