Before installing or servicing system, always turn off main power to system. There may be more than 1 disconnect switch. Turn off accessory heater power if applicable. Electrical shock can cause personal injury or death.
Unit must not be installed where freezing temperatures could occur. Do not install unit on the furnace or fan coil jacket. Do not install unit where ends of cooling coil could restrict airflow to the humidifier. Condensation damage could occur if home has closed-off, unheated rooms.
INSTALLATION OF HUMCCLBP2018-A--
BYPASS HUMIDIFIER
Carrier's HUMCCLBP2018-A-- bypass 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 supplyand 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.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Step 4ÐMount the Humidifier (See Fig. 3.)
1.Attach foam tape on inside of mounting flange.
2.Hook bottom notch of humidifier on opening cut in plenum.
3.Push top of humidifier to plenum aligning screw holes with flange.
4.Align, level, and secure using top screws first.
5.Insert bottom screws and tighten all screws for air tight seal.
→Step 5ÐInstall 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.
Do not support weight of bypass duct from humidifier Ð damage could result.
Step 6ÐInstall Drain Line
1.Use 1/2- or 5/8-in. vinyl tubing (field supplied) to connect drain on bottom of humidifier housing to an open drain.
→2. Use supplied worm clamp to hold drain tubing in position over drain fitting outlet.
Unit may leak if drain tubing is misapplied. Do not insert tubing inside of drain fitting outlet.

Step 7ÐMake 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 8ÐInstall 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.
Step 9ÐStart-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.
Step 10ÐFinal 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.
