reservoir cut-out is ush with the inside of the bottom of the
duct for horizontal duct mount. Most ducts are insulated allow for
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.

7. DRILL HOLES AND CUT OPENINGS
Safely predrill eight 1/8” diameter mounting holes in the duct.
These can be drilled through the template at the locations
indicated on the template.
Safely remove the air duct material by cutting along the
mounting template cut lines.
Insert and/or mount the Humidier and secure it to the duct with
the provided screws.

A. WATER SUPPLY USING THE SADDLE VALVE FURNISHED WITH
UNIT.
Installation instructions for the saddle valve are printed on the
plastic bag containing the saddle valve and its components.
Tap into a 1/2” or 3/4” domestic cold water line. Avoid
connecting to water lines from a Reverse Osmosis system or
De-ionized water systems. The supply water must read a
minimum of 25 ppm in order for the Steam unit to reliably
sense the water.
NOTE: Never install the saddle valve on the bottom of the water
pipe. Sediment in the water pipe may clog the saddle valve. Flush
the line before connecting to the unit. When tightening the hex
compression nut, tighten only enough to assure there are no
leaks.
NOTE: Saddle valves do not meet plumbing codes in some areas. A
“T” tting with a valve may be required to meet code or, if low
water pressure causes frequent water alerts on the steam
humidier.
NOTE: Flush the new water line before connecting it.
NOTE: The use of City water or Municipal water is preferred.
Softened water is preferred over untreated well water. Specify the
Optional WC-25 disposable water lter for treating any water
supply that is very high in mineral content. Refer to water
conditioning system supplement insert information on page 24.
NOTE: Use optional water hammer arrester (WH-100) if water
spikes occur (pipes bang) during ll ups. Refer to water hammer
arrester supplement insert information on page 23.
B. OVERFLOW & DRAIN LINES - Required Criteria
B. OVERFLOW & DRAIN LINES - Required Criteria
The use of an overow line and drain line is always required.
Use the supplied 1/2” ID high temperature hose. Slip the
hose over the 1/2” OD “T” drain tting and use a hose clamp
to secure. Route the hose to a suitable drain, avoiding kinks,
traps and sharp objects.
DO NOT route the hose above the
DO NOT route the hose above the
humidier. Failure to install all necessary drain lines may re-
sult in water leaks during normal operating conditions, and
voids all warranties.
When routing the S2000 drain hose into a condensate
pump, be sure to cut the end of the hose at a sharp angle
to prevent the hose from bottoming out in the pan. It could
result in poor draining or no draining at all. Failure to do so
may result in water backing up into the S2000 reservoir and
eventual overow. See Figure 5.

9. MOUNTING THE STEAM HUMIDIFIER
9. MOUNTING THE STEAM HUMIDIFIER
Use gasket material to seal where the front plate or tank
ange contacts the duct-work. Place the humidier
reservoir into the opening in the duct and secure with eight
(8) sheet metal screws. Refer to page 8 and 9 for additional
humidier mounting location information.
NOTE: If the duct-work will not support the unit in a level
position with the reservoir full of water, the duct-work
must be reinforced. Both steam models weigh approximate-
ly 9 lbs. empty and approximately 15 Lbs. when full of water.
10. STEAM OPERATION - Required Criteria
10. STEAM OPERATION - Required Criteria
Because of the high humidity output of the steam
humider, it must not be operated without proper fan
operation. The steam humidier is designed to be
"Dominant" over the HVAC System Blower. The "System"
Blower will be operated by the humidier when the water
tank temperature reaches 170° F. A minimum of 800 cfm @
800-900 fpm is required for proper operation of the steam
humidier. Lower velocities may result in excessive
condensation inside the duct. See Air Proving Feature under
section 11 B. See Variable Speed on Page 9.
A temperature sensor is mounted in the water reservoir of
the humidier. As the water temperature increases to about
170° F, the computer closes a set of blower relay contacts
to start the HVAC system fan. When the water cools to
about 140° F, the computer will open the relay contacts to
shut o the fan. This operational sequence drastically
decreases the chances of condensation occurring inside the
duct-work.
