5. Attach transfer tube to solenoid valve and insert free end
into inlet fitting on top of unit housing.
6. Attach bridge rectifier to solenoid valve.
7. Insert sheet metal screws into lower holes in plenum,
pre-drilled using template.
8. Tighten screws until heads protrude approximately 3/16-in.
9. Hang humidifier on bottom screws and push top of humidi-
fier to plenum, aligning top screw holes with flange, and
insert screws.
10. Align and level unit.
11. Tighten all screws for air tight seal.
V. INSTALL BYPASS DUCT
Attach field-supplied 6-in. diameter duct, elbow, or starting collar
with field-supplied 1/4-in. zip screws. Install supplied 6-in. damper
in 6-in. duct connector.
IMPORTANT: On systems with central cooling, the damper
should be closed during cooling season to prevent bypass air.
CAUTION: Do not support weight of bypass duct from
humidifier damage could result.
VI. INSTALL DRAIN LINE
1. Use 5/8-in. ID vinyl tubing (field supplied) to connect drain
on bottom of humidifier housing to an open drain.
2. Use worm clamp to hold drain tubing in position over drain
fitting outlet.
CAUTION: Unit may leak if drain tubing is misapplied.
Do not insert tubing inside of drain fitting outlet.
3. Make sure line is free of traps due to sagging and has
sufficient pitch to drain.
VII. MAKE WATER CONNECTION
If garden hose is not used for water supply:
1. Mount saddle valve on water line according to instructions
supplied with valve.
2. Run 1/4-in. diameter (water line grade) tubing from saddle
valve to adapter on solenoid valve and tighten compression
fittings.
IMPORTANT: If water pressure is higher than normal (60 psi),
use noise suppression disk included in parts bag. (Read water noise
reducer note located inside package for instructions). For normal
operation, saddle valve need only be opened 1 full turn to meet
performance requirements.
3. Open valve and check installation for leaks.
NOTE: Saddle valve is self piercing on copper lines; 1/4-in. hole
must be drilled in steel or iron pipes. Use only a grounded drill or
a hand drill to avoid shock hazard. Turn off water and drain the
pipe prior to drilling 1/4-in. hole.
VIII. INSTALL HUMIDISTAT AND COMPLETE WIRING
1. Mount humidistat on inside wall, or return-air duct in
accordance with section INSTALLATION OF HUMIDIS-
TAT on page 10.
2. Wire brown low-voltage leads to furnace control board, or
install a field-supplied step-down transformer
115vac/24vac 60Hz to power solenoid valve. (See Fig. 4.)
Make sure bridge rectifier is attached to coil of solenoid
valve.
NOTE: Wiring must comply with National Electrical Code and
any local codes or ordinances that may apply.
IX. START-UP
1. Open saddle valve to permit water flow to the solenoid.
2. Check all connections for water leaks.
3. Set thermostat to call for heat. Set humidistat for highest
humidity setting making sure contacts are closed. After a
few minutes of operation, check the drain connection for
leaks and to see if water is flowing through humidifier.
4. Reverse thermostat and humidistat settings to insure proper
shutdown.
5. Reset thermostat to normal setting. Reset humidistat to
recommended setting.
X. FINAL STEPS
Attach humidifier maintenance instruction sticker to a visible
location.
1. Inform homeowner of proper operation, maintenance, and
humidistat setting.
a. If unit is installed during cooling season, close bypass
damper, set humidistat for summer setting (OFF or
lowest setting).
b. If installed during heating season, set unit for normal
operation.
INSTALLATION OF HUMBBWTR2019-A--
BYPASS WATER SAVER HUMIDIFIER
Bryant’s HUMBBWTR2019-A-- bypass water saver humidifier
can be installed on either the supply or return plenum of a
forced-air system. This unit requires an external bypass duct
between the supply- and return-air ductwork.
It is recommended to install the humidifier where it can be easily
serviced. If this humidifier is installed with a central cooling
system the factory-supplied 6-in. shutoff damper must be installed
to close during the cooling season to prevent bypass air. Always
install humidifier downstream of an electronic air cleaner.
