Step 6—Mount Solenoid Valve
The water solenoid valve should be mounted on top of humidifier
enclosure.
1. To mount solenoid on top, see Fig. 10.
a. Firmly press valve into the top inlet hole on enclosure. Seat
valve flush against inlet hole.
2. If alternate mounting of solenoid is required, see Fig. 11.
a. To mount solenoid on side, use 3/8-in. ID, 1/2-in. OD vinyl
tubing (field supplied). Place tubing onto valve stem and
secure with clamp.
b. Mount valve upside down securing to side of housing.
c. Place open end of tubing into the top inlet hole.
IMPORTANT: Be careful not to kink tubing.
Step 7—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.
Step 8—Install Humidistat and Complete Wiring
1. Mount humidistat on inside wall, or return-air duct in accor-
dance with section INSTALLATION OF HUMIDISTAT on
page 10.
2. Wire red and blue low-voltage leads. (See Fig. 6.)
3. Plug power cord in to 115-vac 60Hz source.
NOTE: Wiring must comply with National Electrical Code and
any local codes or ordinances that may apply.
Step 9—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 rec-
ommended setting.
Step 10—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 set humidistat for
summer setting (OFF or lowest setting).
b. If installed during heating season, set unit for normal
operation.
INSTALLATION OF HUMCCSBP2017-A--
BYPASS HUMIDIFIER
Carrier’s HUMCCSBP2017-A-- bypass humidifier can be in-
stalled 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.
