IX. START-UP

1.Open saddle valve to permit water to flow to the solenoid valve.

2.Check all connections for water leaks.

3.Set thermostat to call for heat. Set humidistat at highest humidity setting to be sure the 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.

INSTALLATION OF HUMIDISTAT

The humidistat provides automatic control of humidifiers in central heating systems. It is designed for low voltage, wall, or surface duct mounting and contains a SPST snap-acting dustproof switch.

CAUTION: Disconnect power supply before making wiring connections to prevent possible electrical shock and equipment damage. Make wiring connections in accordance with Installation Instruction supplied with the humidifier.

1.Installer must be a trained, experienced service person.

2.Disconnect power supply before beginning installation.

3.Conduct a thorough checkout before leaving installation.

I. WALL MOUNTING (LOW VOLTAGE)

1.Choose a location for humidistat about 5 ft above floor on inside wall with average room temperature and relative humidity conditions. Maximum ambient temperature of selected location must not exceed 125°F. Humidistat may be mounted directly on wall.

2.Drill a small hole in wall and run low-voltage wiring to location chosen. Pull about 6 in. of wire through hole. Plug opening to prevent drafts from affecting humidistat opera- tion.

3.Remove knob, faceplate, and switch assembly from case by following steps listed below.

a.Remove knob by pulling away from casing. (See Fig. 18.)

b.Lift off faceplate, starting at right side. Left end of faceplate protrudes under lip of casing. (See Fig. 18.)

c.Remove switch by removing 2 screws in back of casing. Pressing tab on case. Lift out control. (See Fig. 19.)

4.Make connections to screw terminals on switch assembly. Re-install switch into casing Ð secure with 2 short screws.

5.Mount case horizontally over wires directly to wall using 2 long screws provided.

6.Replace faceplate and knob.
