Step 6ÐMount 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 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 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 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 rec- ommended 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 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.
