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 69-2413EF—09 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
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.
MCR29871
Fan:
Fan humidiers use the fan inside the humidier
to pull duct air through the humidier. Honeywell
strongly recomends mounting the HE300 on
the supply duct for maximum humidication
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 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—09 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.
Location must also have access to 120 VAC power.
For the HE300 Fan humidier, the power cord is 6 feet
long.
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: 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.

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.

STEP FIVE: Bypass Duct Installation
On the duct opposite the humidier Bypass install, cut
a 6-in. diameter duct hole.
• If the humidier is on the supply duct, the 6-in.
diameter hole should be on the return.
• If the humidier 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.
Use rigid or aluminized exible 6-in. duct to connect
the starter collar to the humidier bypass port.
Secure the duct to the humidier 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.

Water Supply and Drain Connections
STEP ONE: Connect the Water Supply
Use hot or cold water.
Cut the water line so it reaches from the humidier to
the main water supply tap.
Insert the water line into the gray quick connect
tting. Insert it fully, and apply modest pull pressure to
ensure a tight t.
Note: The quick connect tting can be removed if you
prefer to use a standard 1/4-in. brass compression
nut plumbing connection. Do not remove the conical
screen if you select this option.
STEP TWO:Tap into a Water Line
• Consult local codes for proper plumbing.
• Use the saddle valve provided or a T-tting 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 humidier water line
to the water valve.

PLUMBING
STEP THREE: Connect to the Water Drain
• Consult and follow local plumbing codes for drain
pipe size and ow requirement.
• The ideal installation is directly to the main oor
drain using the rubber hose provided.
• If direct oor drain access is not available, see
“Appendix C: Advanced Draining.”
Connect the 1/2-in. drain hose provided to the drain
tting on the bottom of the humidier.
Use the hose clamp provided to secure the drain hose
to the tting.
Route the drain hose to the oor drain. The hose must
have a continuous downward slope.
Direct the hose outlet into the oor drain. Secure
the hose to reduce the risk of water pooling or
splashing as it drains from the humidier.
HE300 ONLY: Return Duct Installation
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.
MCR29881
Before proceeding to Wiring:
