Safety Definitions and Precautions

Safety Definitions

These safety terms identify information you must read prior to installing or operating the humidifier.

CAUTION: Indicates a hazardous situation which, if not avoided, could cause bodily injury or property damage.

WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

Safety Precautions

Make sure you read and understand the following safety hazards before installing, using, or working with the humidifier:

CAUTION: Voltage Hazard.

Can cause electrical shock or equipment damage.

Disconnect HVAC equipment and any electrical outlet being used for the humidifier installation.

WARNING: Electrocution and Water Hazard.

Can cause death, blindness, and water damage to the home and HVAC Equipment.

CAUTION: Condensation, Fire, and Freezing Water Hazard.

Can cause failure of fan or limit control or result in water damage to home.

What to Expect From Your Humidifier

The installer should review these points with the homeowner and answer any questions they have before leaving the job site.

• Achieving Humidity Setpoint. It may take up to a week of continuous operation to achieve the humidity setpoint, especially if the home is dry when the humidifier is installed. This also depends on such factors as weather, size of home, furnishings in the home, and insulation.
• Ideal Humidity. Home building industry experts cite 35% relative humidity as ideal for comfort and safeguarding the home during the typical dry season. Homeowners can adjust to their own comfort or until there is condensation on the windows. Lower the setpoint if condensation appears.
• Unit Not Humidifying. If the humidifier is not running but the humidity is below the setpoint, the humidity control may have a frost protection setting to prevent window condensation from appearing.
• Home Ventilation. Excessive ventilation sends moist air outside and replaces it with dry air. This can make it hard to maintain the humidity setpoint. If installing a ventilator, use a solution that retains moisture. An Energy Recovery Ventilator (ERV) is recommended.
• Cleaning Requirements. The humidifier pad should be changed at least once a year. The water trays of the humidifier should be cleaned at that time. See Operation and Service section for details.
• Energy Consumption. It is important to explain that with any humidification solution there is a cost associated with converting water to humidity. The humidifier utilizes the air heat and air flow in your ducting to make this conversion, which has gas and/or electric costs that depend on your HVAC system type and setup.

Important Installation Requirements

Failure to comply with these requirements will result in voided warranty, improper installation, and service callbacks.

Personal Safety

• Wear safety glasses while installing the humidifier.
• Do not cut into any air conditioning or electrical line.
• Follow professional safety standards and all local regulations for plumbing, electrical, and mechanical considerations.

Mounting Location

• Mount the humidifier in a level position to avoid water damage and ensure maximum output.
• Location must have access to a water line, drain, and power.
• Do not install the humidifier where the ambient temperature is lower than 34^ (1.1°C) or higher than 90^ (40°C).
• Mounting area must be strong enough to support humidifier weight (up to 10 lbs).
• Do not mount directly to ductboard.
• If used near a pool or spa, make sure the humidifier can not fall into the water or be splashed.
• Ensure that the top and bottom covers of the humidifier can be removed and that the pad is accessible from the chosen location.

Water Supply and Drainage

- Consult local plumbing codes for drain size, material, and maximum temperature allowed.

If Replacing an Old Bypass Humidifier

The humidifier is not identical in size and shape to other bypass humidifiers. Before performing a retrofit installation, you might need to:

• Dry-fit the humidifier to the existing ducting, plumbing, and wiring before fastening it to the duct to ensure that the existing connections will reach the humidifier.
• If the duct opening of the old humidifier is not the right size for the humidifier, choose a new location or cover the old opening with a piece of sheet metal and cut a new opening specifically for the humidifier using the template provided.

Cross Reference Table

Choosing a Mounting Method

Bypass humidifiers use the pressure difference between the supply and return to move duct air through the humidifier. Access to both the supply and return are required. The bypass humidifier can be positioned on either the supply or return duct.

3D technical illustration of a pipe fitting inside a mechanical housing (no text or symbols)

Before beginning Mounting:

☐ I have confirmed local codes for proper plumbing practices.
☐ I have chosen an installation location that meets the requirements on page 4.

STEP ONE: Select the Mounting Location

1 2 2 3 MCR29877

Choose a location that has access to a water supply pipe. Cold or hot water can be used.

Select a vertical or horizontal surface on the HVAC duct work, with adequate space clearances, where the humidifier can be mounted.

Ensure the location is near a drain. Consult local plumbing codes for proper drainage. If no main floor drain is available, see "Appendix B: Advanced Draining."

Location must also have access to 120 VAC power to the included transformer.

STEP TWO: Install Mounting Template to the Duct

M29673 M29874A 1 2 3 BYPASS 1/2 (13) A-COIL

Position the template on the duct.

- Make sure the template is level and in the desired position on the duct. Peel adhesive backing and press template firmly into place in desired mounting location.

Ensure proper clearances from the air-conditioning coil inside the duct.

NOTE: The HE400 humidifier extends into the duct 1/2 inches.

- For best performance, maintain at least 24 inches downstream of open air space inside the duct.

Cut the sheet metal, following the template outline.

Bypass Model Installation

STEP THREE: Configure Humidifier

MCR29875

Configure the humidifier bypass outlet to the side that best fits the application.

If the bypass needs to be on the other side, remove the top and bottom covers.

Pull the bypass clamps apart from center to remove the bypass; snap it back into place with the outlet on the desired side.

STEP FOUR: Mounting

① ② MCR29870

Ensure that the pad is accessible. The handle of the pad holder and side panel of the humidifier can be switched so the pad holder can be removed (opposite side of the bypass duct opening).

To remove the handle for the pad holder, slide it toward the back of the humidifier, then pull it away from the humidifier.

To remove the opposite side panel, place a screwdriver into the two slots on the back of the humidifier, and pop the panel off.

Snap the pad holder handle and side panel back into place in the desired configuration.

Secure the support hooks on Bypass models to the bottom lip of the hole.

Push the top of the humidifier back against the duct.

Verify the humidifier is level and fasten the humidifier to the duct using two self-drilling sheet metal screws provided.

Bypass Model Installation

STEP FIVE: Bypass Duct Installation

1 2 MCR29933

On the duct opposite the humidifier Bypass install, cut a 6-in. diameter duct hole.

• If the humidifier is on the supply duct, the 6-in. diameter hole should be on the return.
• If the humidifier is on the return duct, the 6-in. diameter hole should be on the supply.

Secure a 6-in. round duct starter collar into the 6-in. duct hole.

1 2 MCR29878

Use rigid or aluminized flexible 6-in. duct to connect the starter collar to the humidifier bypass port.

Secure the duct to the humidifier port with self-drilling sheet metal screws using the pre-drilled holes on the bypass port. For added seal, wrap sheet metal tape around the duct to port connection point.

Bypass mounting is complete. Go to page 12.

Before proceeding to the next step:

☐ I secured the humidifier to the duct as instructed.

Water Supply and Drain Connections

STEP ONE: Connect the Water Supply

Technical diagram showing a device with three labeled parts: connection to cable, assembly with arrows indicating motion, and a separate view of the cable being inserted.

Cut the water line so it reaches from the humidifier to the main water supply tap.

Insert the water line into the gray quick connect fitting. Insert it fully, and apply modest pull pressure to ensure a tight fit.

Note: The quick connect fitting can be removed if you prefer to use a standard 1/4-in. brass compression nut plumbing connection. Do not remove the filter if you select this option.

STEP TWO: Tap into a Water Line

T-fitting Manual Shutoff Valve Water Supply Line Saddle Valve M29605

• Consult local codes for proper plumbing.
• Use the saddle valve provided or a T-fitting and manual shutoff valve to tap into the water line.
• Refer to the literature included with the valve you chose and the local plumbing codes. Use proper technique for the valve.
• Connect the other end of the humidifier water line to the water valve.

STEP THREE: Connect to the Water Drain

M38968

• Consult and follow local plumbing codes for drain pipe size and flow requirement.
• The ideal installation is directly to the main floor drain using the rubber hose provided.
• If direct floor drain access is not available, see "Appendix C: Advanced Draining."

Connect the 1/2-in. drain hose provided to the drain fitting on the bottom of the humidifier.

Use the hose clamp provided to secure the drain hose to the fitting.

Route the drain hose to the floor drain. The hose must have a continuous downward slope.

Direct the hose outlet into the floor drain. Secure the hose to reduce the risk of water pooling or splashing as it drains from the humidifier.

Before proceeding to Wiring:

☐ I have connected the water supply line to the humidifier and the main water tap.
☐ I have installed the drain connection.
☐ I have checked all plumbing connections for leaks.

Before Wiring the Humidifier

CAUTION: Voltage Hazard.

Be sure the humidifier is not plugged in before beginning wiring.

Before wiring the humidifier:

☐ I understand and will comply with applicable local wiring codes and regulations.

Mounting the Outdoor Sensor

(Not required if window protection isn't needed)

Location

Mount the sensor where:

- it cannot be tampered with.

• there is good air circulation.

- surface is flat.

- wire distance between sensor and humidistat is less than 200 feet.

- it can measure true outdoor ambient temperature.

Do NOT mount the sensor:

- in direct sunlight.

• where snow, ice or debris can cover it.

- where hot or cold air blows on the sensor. (For example, a discharge line from an outdoor compressor unit, vent or fan can cause inaccurate temperature readings.)

Steps to mount the sensor

1. Remove the sensor from the mounting clip.

2. Mark the area on the location selected for mounting the sensor mounting clip.

3. Mount the clip. Image on right shows typical locations for outdoor sensor.

Diagram illustrating window frame installation with magnified detail and directional arrow, showing structural components and measurement indicators.

Wiring the Outdoor Sensor

CAUTION: Electrical Interference (Noise) Hazard. Can cause erratic system operation.

Keep wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts and large power distribution panels.

Use shielded cable to reduce interference when rerouting is not possible.

Be sure wires have a cable separate from the thermostat cable.

Do not route temperature sensor wiring with building power wiring, next to control contactors or near light dimming circuits, electric motors or welding equipment.

Avoid poor wiring connections.

Avoid intermittent or missing building earth ground.

CAUTION: Electrical Shock Hazard. Can cause electrical shock or equipment damage.

Disconnect power supply before connecting wiring.

Wiring must comply with applicable codes, ordinances and regulations:

1. Wire the C7089 Outdoor Sensor to the S terminals on the humidity control. If leadwire provided with C7089 is not long enough (60 in.), run a cable to a hole at C7089 location.

2. Using color-coded, 18-gauge, shielded thermostat wire is recommended. For example of general wiring of C7089, see image at right.

3. Pigtail wiring can be used.

4. Mount C7089 in its mounting clip.

5. Plug wiring hole using nonhardening caulk or putty.

SLOTS ON BACK OF HumidiPRO WALLPLATE TABS 0 TABS M34583

Checkout

Allow C7089 Outdoor Sensor to absorb outdoor air for a minimum of twenty minutes before taking a reading. With an accurate thermometer ( ±1^ F [0.5°C]), measure the temperature at the sensor location, allowing time for the thermometer to stabilize before reading.

Then verify the sensor accuracy by going into installer Test #20. This will show you the outdoor temperature.

Calibration

The C7089 Outdoor Sensor is calibrated at the factory. However, you can offset the outdoor sensor reading using Function 35 in Installer Setup.

You've just installed your Humidity Controller!

This Humidity Control has been preprogrammed to the ideal settings for most homes.

If you installed this control with an outdoor sensor, the control will operate in AUTOMATIC MODE, which automatically adjusts humidity to help prevent window condensation.

Technical diagram showing cable installation components with numbered labels and a magnified inset of the device's cable connection.

Snap the bottom cover into place.

Turn on the water supply at the saddle valve or T-fitting and manual shutoff valve. Water will flow to the humidifier but will not pass through the pad until the humidity control is turned on.

Turn on power to the transformer that powers the humidifier.

Turn the Damper Position knob on the bypass outlet so that it is parallel to the bypass outlet.

Turn the humidity control to On.

• If your wiring is configured for operation only with heat or fan, make the appropriate system demands to allow humidification.
• Make sure air is blowing through the ductwork with the humidifier call.

Remove the humidifier's top cover to verify water flow through the top tray and into the pad.

Check all water line and drain connections to ensure there are no leaks before leaving the job site.

- Check for leaks immediately after turning the main water supply on, and again after 15 minutes of humidifier operation.

Turn the setpoint to the homeowner's desired level when testing is complete. If humidity is not needed, set the control to Off, and turn the Damper Position knob on the bypass outlet so that it is perpendicular to the bypass outlet.

Routine Maintenance

The humidifier pad should be replaced at least once per year. This is critical for optimal performance of the unit. This can be done at the beginning or the end of the dry season. The humidifier design makes this annual replacement quick and easy, providing one-step access to the pad.

1. Pad can be replaced from the side by gripping the black handle and pulling out, or from the front by removing the humidifier's top cover and rocking the pad forward and out Humidifier pad might remove from other side of humidifier, depending on installation.

Troubleshooting

Problem What To Look For What To Do

Low humidity Furnace blower not operating	1. Reset circuit breaker or check for blown fuse.2. Check that the furnace power is on.3. Check all external wiring connections.4. Check the humidity control setting.
Rapid air changes or drafts	1. Keep doors and windows closed.2. Close fireplace damper when not in use.3. Keep exhaust fan running time to a minimum.4. Seal around doors and windows.
High humidity Condensation on walls 1. Turn off humidity control and water until condensation is completely evaporated.
Heavy condensation on windows	1. Turn humidity control down low enough to eliminate condensation caused by moisture. If moisture persists, more ventilation is needed.
