Carrier logo label BYPASS UNITS ONLY VERTICAL HORIZONTAL BYPASS UNITS DRILL (2) HOLES IN DUCT FOR #8 SHEETMETAL SCREWS "N" COIL A98363 > Fig. 1—Installation of HUMCCLBP2018-A-Bypass- Type Humidifier Step 2—Select Location (See Fig. 1.) Humidifier may be installed on either supply or return plenum. If furnace has air conditioning coil, be sure humidifier does not interfere with coil ends. Remember to provide clearance for maintenance and evaporator pad removal. Step 3—Prepare Plenum Opening (See Fig. 2.) 1. Use template for marking humidifier opening. 2. Tape in place on plenum making sure template is level. IMPORTANT: For humidifier to operate properly it must be level and mounted on a vertical surface. 3. Drill four 1/8-in. holes in plenum. 4. Cut opening in plenum using heavy solid lines on template as a guide. TEMPLATE PLENUM LEVEL A97096 Fig. 2—Preparing Plenum Opening FOAM TAPE NOTCH SCREWS A98364 ® Fig. 3—Mounting the Humidifier Step 4—Mount 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 5—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. Do not support weight of bypass duct from humidifier — damage could result. Step 6—Install 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. 3. Make sure line is free of traps due to sagging and has sufficient pitch to drain. 2 HUMIDIFIER HUMIDISTAT BROWN BROWN 24VAC FURNACE TRANSFORMER HUMIDIFIER HUMIDISTAT (FIELD SUPPLIED) 115V FIELD WIRING RED BLU 24V A98365 ® Fig. 4—Installation of Humidistat on Bypass-Type Humidifier 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 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 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 recommended setting. Step 10—Final Steps Attach humidifier maintenance instruction sticker to a visible location. 1. Inform homeowner of proper operation,...
