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

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.

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.
MCR29871
Fan:
Fan humidifiers use the fan inside the humidifier
to pull duct air through the humidifier. Access to
only the supply or the return is required.
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—01 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. For bypass
installation, access to both the return and supply are
required. Both humidifier models can be mounted to
either the supply or the return.
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.
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.
Use a marker to trace the template outline onto the
duct, then remove the template.
Cut the sheet metal, following the template outline.
