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.

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 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.
• Cleaning Requirements. At least once per year it is recommended to change the humidier pad and clean
the water trays of the humidier. 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.
What to Expect From Your Humidier
Humidier 33-00067EF—01 3

GETTING
STARTED
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.
Important Installation Requirements
Failure to comply with these requirements will result in voided warranty, improper installation, and
service callbacks.

MOUNTING
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.
MCR29871
Choosing a Mounting Method
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 33-00067EF—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 humidier can be mounted.
Ensure the location is near a drain. Consult local
plumbing codes for proper drainage. If no main
oor drain is available, see “Appendix C: 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 rmly into place in desired
mounting location.
Ensure proper clearances from the air-conditioning
coil inside the duct.
NOTE: 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: 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.
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.

MOUNTING
STEP FOUR: Mounting
Secure the support hooks on Bypass models to the
bottom lip of the hole.
Push the top of the humidier back against the duct.
Verify the humidier is level and fasten the humidier
to the duct using two self-drilling sheet metal screws
provided.
