Safety Denitions and Precautions

Safety Denitions

These safety terms identify information you must read prior to installing or operating the humidier.

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

humidier:

CAUTION: Voltage Hazard. Can cause electrical shock or equipment damage. Disconnect HVAC equipment and any electrical outlet being used for the humidier 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.

Humidier 69-2413EF—17

What to Expect From Your Humidier

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 humidier 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 humidier 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.

STARTED

GETTING

• Cleaning Requirements. The humidier pad should be changed at least once a year. The water trays of the

humidier should be cleaned at that time. See Operation and Service section for details.

• Energy Consumption. It is important to explain that with any humidication solution there is a cost

associated with converting water to humidity. The humidier utilizes the air heat and air ow in your ducting to make this conversion, which has gas and/or electric costs that depend on your HVAC system type and setup.

Humidier 69-2413EF—17

GETTING

STARTED

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 humidier.

• 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 humidier 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 humidier where the ambient temperature is lower than 34°F (1.1°C) or higher than 90°F

(40°C).

• Mounting area must be strong enough to support humidier weight (up to 16 lbs [Fan] or 10 lbs [Bypass]).

• Do not mount directly to ductboard.

• If used near a pool or spa, make sure the humidier can not fall into the water or be splashed.

• Ensure that the top and bottom covers of the humidier 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 Humidier

The humidier is not identical in size and shape to other Honeywell bypass humidiers. Before performing a retrot installation, you might need to:

• Dry-t the humidier to the existing ducting, plumbing, and wiring before fastening it to the duct to ensure that the existing connections will reach the humidier.

• If the duct opening of the old humidier is not the right size for the humidier, choose a new location or cover the old opening with a piece of sheet metal and cut a new opening specically for the humidier using the template provided.

Humidier 69-2413EF—17

MCR29871

Choosing a Mounting Method

Whether you purchased a Bypass or Fan humidier will determine how your humidier will be installed:

Which humidier do you have?

Bypass:

Bypass humidiers use the pressure difference

between the supply and return to move duct

air through the humidier. Access to both the supply and return are required. The bypass humidier can be positioned on either the supply or return duct.

Fan:

Fan humidiers use an internal fan to move duct air through the humidier pad and back into the duct for distribution throughout your home. The

fan model is commonly installed directly onto the

supply (hot) air duct of your HVAC system.

The fan model can be installed on the return

(cool) air duct, if the location permits. When

a return-side installation is used, it is highly recommended to plumb warm water since

humidity is produced by evaporation.

MOUNTING

Before beginning Mounting:

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

Humidier 69-2413EF—17

Bypass Model Installation

STEP THREE: Congure Humidier Bypass

Congure the humidier bypass outlet to the side that best ts the application.

If the bypass needs to be on the other side, remove

the top and bottom covers.

MOUNTING

Unplug the damper wire and plug in on the other side

(HE150/HE250 only).

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

the desired side.

Ensure that the pad is accessible. The handle of the pad holder and side panel of the humidier 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 humidier, then pull it away from the humidier.

To remove the opposite side panel, place a screwdriver into the two slots on the back of the

humidier, and pop the panel off.

Snap the pad holder handle and side panel back into place in the desired conguration.

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.

• Using color-coded, 18-gauge, shielded thermostat wire is

recommended. For example of general wiring of C7089, see image at right.

• Pigtail wiring can be used.
