BYPASS HUMIDIFIER
.
Bryant’s HUMBBLBP2018-A-- bypass humidifiercanbe 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 bypass duct must have a shutoff damper to close during
the cooling season. Always install humidifier downstream of an
electronic air cleaner.

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.
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 HUMIDISTAT 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.
