Mounting Steam Power Humidifier

Mount Horizontally Using Mounting Bracket (Preferred Mounting Method)
IMPORTANT
Be sure duct is at least 11 in. (280 mm) wide to use this mounting method.
The duct is the strongest when using the mounting bracket method because less duct reinforcement is required to support the bracket using this bracket location It is important to evaluate if reinforcement is necessary to help support the weight of the humidifier and keep it level

Measure and mark an 8-1/2 in. (215 mm) x 11-1/2 in. (290 mm) outline on the bottom of the duct in the desired location.
Drill 3/8 in hole (10 mm) within the outlined mounting hole location See Fig. 5.
IMPORTANT
Be sure to carefully cut around the marked lines.
Use the tin snips to cut around the outline.
Remove the sheet metal.
Place the two 8-1/2 in. (215 mm) S-cleat pieces (provided) on the narrow sides of the rectangular opening so the opening (slot) protrudes down and out from the duct.
Place the 11-1/2 in. (290 mm) piece of S-cleat on the long side of the rectangular opening closest to the center of the duct so the opening (slot) shows below the duct.
Use two machine screws and nuts (provided) to attach the mounting bracket (L-shaped with six holes) to the top/front surface of the humidifier. (The humidifier is now ready for mounting.)
Slide the humidifier tabs into the installed S-cleat Be sure the back tab engages completely with the S-cleat and the mounting bracket touches the side of the duct
Using the mounting bracket as a guide, drill three 7/64 in. (3 mm) holes through the duct
Secure the humidifier to the duct with three no. 8 sheet metal screws (not provided)

Mount Horizontally on Reinforced Duct
This method usually requires duct reinforcement to support the humidifier weight and keep it level See Fig. 3. The mounting bracket is not used.

Measure and mark an 8-1/2 in. (215 mm) x 11-1/2 in. (290 mm) outline on the bottom of the duct in the desired location.
Drill 3/8 in hole (10 mm) within the outlined mounting hole location
IMPORTANT
Be sure to carefully cut around the marked lines.
Use the tin snips to cut around the outline.
Remove the sheet metal.
Place the two 8-1/2 in. (215 mm) S-cleat pieces on the narrow sides of the rectangular opening so the opening (slot) protrudes down and out of the duct.
Place the 11-1/2 in. (290 mm) piece of S-cleat on the long side of the rectangular opening, opposite the two holes previously drilled Position so the opening (slot) protrudes down and out of the duct.
Slide the humidifier tabs into the installed S-cleat. Be sure the back tab engages completely with the S-cleat.
Secure the humidifier to the duct with two no. 8 sheet metal screws (not provided)

Mount Horizontally on Vertical Duct

Horizontal mounting on a vertical duct requires the installation of a duct extension. See Fig. 4. Additional duct reinforcement may also be necessary to help support the humidifier weight and keep it level. Create and install the duct extension.
Then follow steps 1 through 10 in Mount Horizontally Using
Mounting Bracket section to complete installation.
Place a drain pan correctly connected to a suitable drain below the humidifier. See Fig. 4.

Mount Two-Stage Water Treatment System Bracket to Wall
NOTE: Be sure bracket is level.
Use four screws (not provided) to secure mounting bracket to exposed wall studs or flat wall through mounting holes provided See Fig 6.

NOTE:

Be sure there is an accessible drain near the water treatment system.
Plan system location considering 20 ft (6m) cable (provided) to connect water treatment system to humidifier.
Be sure there is adequate clearance above and below the system to replace the filters See Fig.12.

WIRING

All wiring must comply with local codes and ordinances. When selecting a location for mounting the humidifier, be sure connections can be made to the power source without using an extension cord.

WARNING

Voltage or Fire Hazard.
Can cause death or fire.
Use a receptacle rated at 120 Vac, 15/20A (NEMA configuration 5-1 SR) for the HE440A Humidifier

Equipment Fan Applications
CAUTION

Moisture Condensation and Wiring Hazard.
Moisture can destroy furnace electronic controls and miswiring can burn out electrical components.
Do not alter any heating and cooling system functions.
Be sure to wire only the system fan.

See wiring diagrams in Fig. 7-9 for typical wiring applications.

The humidifier has a sealed switch with a thermostatic sensor that is designed only for low voltage applications The sealed switch is attached to the humidifier wall and is wired through a thermal switch fan plug. The switch is preset to turn on the fan when the water temperature is 170° F (76°C) and turn off the fan when the water temperature falls below 120° F (50°C).

Heat Pumps

No wiring diagrams can be suggested due to many variations and wiring complexity of heat pumps If humidifier control fan operation is desired, be sure to design a safe control circuit using equipment diagrams and tracing the equipment wiring
In heat pump applications, a fan sail switch must be installed due to almost continuous system fan operation. Wire the fan sail switch in series with the low voltage humidity control circuit so the humidifier is on only when the fan is operating. (In most cases, the humidifier does operate in conjunction with the system fan.)
NOTE: Wiring the humidifier to operate with the system fan limits the humidification output

Variable-Speed Motors
Continuous speed on variable speed motors may need to be increased to provide enough air flow to prevent condensation inside the ductwork. Minimum recommended air flow, under most conditions, would be 400 cfm (680 cmh) in the duct where the humidifier is mounted.

Water Treatment
Use cable (provided) to connect plug end to humidifier and wire to solenoid using wire nuts (provided) See Fig. 10.

Fan Failure Safety Lockout Circuit (HE440)
It is recommended using a fan failure safety lockout circuit that stops the humidifier operation if the system fan fails.
IMPORTANT
Failure to install a fan failure lockout can result in excessive condensation in the event of a motor/ blower failure.
If a safety lockout is used, be sure to design a safety control circuit:

Use equipment diagrams and trace the equipment wiring.
In most cases, a fan sail switch must be installed to allow the humidifier to operate only when the system fan is operating. Wire the sail switch in series with the low voltage humidity control circuit so the humidifier is on only when the system fan is operating.
In cases where the humidifier fan wiring terminals are used to control the system fan, a time delay relay may be required to allow time for the system fan to start, prior to using the sail switch to check for fan operation.

CAUTION

Excessive Condensation Hazard.
Can damage ductwork.
Install fan failure safety lockout circuit to stop humidifier operation if system fan fails.

Humidistat Wiring
Wire the humidistat terminals directly to the humidistat control using low voltage (18 gauge) wiring

PLUMBING

CAUTION

Chemical Hazard.
Can cause damage to environment or air conditioning system.
Do not use any refrigerant line connected to an air conditioner.

NOTE: Use either hard or soft water in the water treatment system.
IMPORTANT
Use only copper tubing to plumb from the humidifier to the water treatment system.

Locate the cold water pipe closest to water treatment system
Plumb between the saddle valve (provided) and the solenoid on the water treatment system See Fig. 11
Use the saddle valve instructions to install the valve (provided)
The valve is self-piercing when installed on copper pipe.
IMPORTANT
- Position the valve so water flows from the top or side to reduce the chance of clogging the valve with minerals.
- Lightly clean the copper tubing ends with fine sandpaper before making any connections.
Run 1/2 in. (12.7 mm) ID drain line from barbed fitting on water treatment system to floor drain.
Run 1/4 in. (6.35 mm) OD copper tubing from water treatment system to humidifier.
IMPORTANT
Do not overtighten the compression nut. Moderate tightness prevents leaking.
CAUTION
Flooding Hazard.
Can cause water damage to equipment or home. Connect humidifier overflow drain to a suitable waste drain.
Use a male 3/8 in. NPT fitting (not supplied) or a 3/4 in. female NPT fitting, standard garden hose (not supplied) to connect the overflow provision of the humidifier to a suitable waste drain.
Support the drain line at several locations to prevent kinks. Be sure to provide support near any heat source.

CHECKING INSTALLATION

After installation is complete, use the following procedure to check humidifier operation:

Turn on the humidifier water supply
Plug in the humidifier and check that the humidifier has power. Wait a few minutes for the reservoir to fill
Turn the Convertible Humidity Control to the highest setting.
Check that the furnace blower comes on to circulate the moist air. The blower may take as long as fifteen minutes to turn on.
Reset the Convertible Humidity Control to a comfortable setting.

OPERATION

The HE440A Humidifier is controlled by the Convertible Humidity Control that is installed either on the interior wall in the living area or on the return air duct.
- Choose the humidity control setting using the combination relative humidity/outdoor temperature setting scale on your humidity control
- Match the dial setting to the outdoor temperature to optimize the humidity level while reducing the moisture condensation on your windows.
- Use Table 2 to adjust the humidity control to the recommended setting
  NOTE: As the outside temperature drops, lower the recommended setting to accommodate the effects of dewpoint. These settings should reduce the accumulation of moisture and ice on the windows and in other areas of the house
Some indoor activities such as cooking, showering and clothes drying can cause excessive levels of humidity and start the accumulation of moisture on the windows
NOTE: If this condition persists for more than a few hours, set the humidity control to the lowest setting to turn off the humidifier. If the condition does not improve, ventilate the house to remove the moisture.
The HE440A Humidifier uses the principle that hot water creates water vapor. As dry air and vapor mix, the relative humidity of the air rises. The humidity control monitors the relative humidity and activates the humidifier accordingly.
When the humidity control calls for humidity, the humidifier underwater heater starts heating the water in the humidifier reservoir. When the water is warm enough, the humidifier activates a relay that turns on the furnace fan The warm dry air from the furnace picks up the water vapor and circulates it through the home. The fan continues to circulate the air until the water cools down and then turns off the fan.
Humidified air feels warmer and more comfortable so you may be able to lower the thermostat heating setpoint and save money on heating fuel bills to give you a more comfortable environment that is also energy efficient.

MAINTENANCE

A regular maintenance program prolongs humidifier life and provides a more comfortable environment Frequency of filter replacement depends on water conditions. Either hard or soft water can be used in the water treatment system
