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.

Humidiﬁer 69-2413EF—05

GETTING

STARTED

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. At least once per year it is recommended to change the humidiﬁer pad and clean

the water trays of the humidiﬁer. 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.

What to Expect From Your Humidiﬁer

Humidiﬁer 69-2413EF—05 3

GETTING

STARTED

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°F (1.1°C) or higher than 90°F

(40°C).

• Mounting area must be strong enough to support humidiﬁer 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 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 Honeywell 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.

Important Installation Requirements

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

service callbacks.

Humidiﬁer 69-2413EF—05

MOUNTING

Whether you purchased a Bypass or Fan humidiﬁer will determine how your humidiﬁer will be installed:

Which humidiﬁer do you have?

Bypass:

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.

MCR29871

Fan:

Fan humidiﬁers use the fan inside the humidiﬁer

to pull duct air through the humidiﬁer. Honeywell

strongly recomends mounting the HE300 on

the supply duct for maximum humidiﬁcation

capacity. If a return duct installation is required,

a trap must be installed in the drain line. A hard

trap is recommended, but a coil in the line,

secured with tape or zip tie, is also acceptable.

See Water Supply and Drain Connections

section for details.

MCR29929

Choosing a Mounting Method

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.

Humidiﬁer 69-2413EF—05 5

MOUNTING

STEP ONE: Select the Mounting Location

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.

Location must also have access to 120 VAC power.

For the HE300 Fan humidiﬁer, the power cord is 6 feet

long.

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.”

STEP TWO: Install Mounting Template to the Duct

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 HE300 Fan model extends into the duct

1-3/4 inch. Bypass models extend into the duct 1/2

inch. Ensure clearance inside the duct.

• For best performance, maintain at least 24 inches

downstream of open air space inside the duct.

Cut the sheet metal, following the template outline.

MOUNTING

STEP THREE: Conﬁgure Humidiﬁer Bypass

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

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 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.

MOUNTING

STEP FOUR: Mounting

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.
