IMPORTANT
• The saddle valve is not designed to regulate
water flow; the valve is either open or closed.
• Be sure to install the saddle valve handle pointing
toward the ceiling to prevent debris from clogging
the solenoid in-line filter.
NOTE: Lightly clean the copper tubing ends with
fine sandpaper before making any
connections.
2. Use 1/4 in. O.D. copper tubing and connect the
saddle valve to the inlet side of the solenoid valve.
a. Place the brass compression nut over the
copper tubing.
b. Slide the brass ferrule over the tubing.
NOTE: Do not over-tighten the compression nut.
Moderate tightness prevents leaking.
c. Insert the tubing into the solenoid valve fitting
and support the valve while tightening the
compression nut.
3. Connect a 1/2 in. hose to the humidifier drain fitting
and run it to a suitable drain.
NOTE: Slope the hose downward for correct
drainage.
&+(&.,1*,167$//$7,21
1. Open the saddle valve.
NOTE: The furnace blower must be operating for
the humidifier to work.
2. Set the thermostat setpoint 10°F (12°C) above the
room temperature.
3. Set the humidity control to a high humidity setting, or
place the humidity control in the test position.
4. Observe the water running out of the drain line to be
sure the humidifier is working correctly.
5. Check for leaks.
6. Reset the thermostat and humidity control to
comfortable settings.
23(5$7,1*+80,',),(5
The Honeywell HE360A Humidifier is controlled by the
H908 Convertible Humidity Control. The convertible
humidity control is installed either on an interior wall in the
living area, or on the return air duct. Choose the humidity
control setting using the combination relative
humidity/outdoor temperature setting scale on the humidity
control dial. Match the dial setting to the outdoor
temperature for optimizing the humidity level to reduce the
moisture condensation on your windows. The table below
can also be used to adjust the humidity control to the
recommended setting.
NOTE: As outside temperature drops, the recommended
humidity control setting is lowered to
accommodate the effects of dewpoint. These
settings should reduce the accumulation of
moisture and ice on the windows and in other
areas of the house.
Some indoor activities such as cooking, showering and
clothes drying can cause excessive levels of humidity and
start the accumulation of moisture on the windows. If this
condition persists for more than a few hours, set the
humidistat to the lowest setting to turn off the humidifier. If
the condition does not improve, ventilate the house to
remove the moisture.
The Honeywell HE360B Humidifier is controlled by the
Honeywell H1008 Automatic Humidity Control with
HumidCalc+. The automatic humidity control is mounted
in the return air duct where it can be exposed to the air
stream of the return air. The HumidCalc+software inside
the automatic humidity control is designed to measure or
infer the outdoor temperature and automatically adjust the
humidity based on the frost factor. The frost factor is set by
the homeowner and allows for variances in furnace size,
window type and insulation. The Automatic Humidity
Control with HumidCalc+requires initial adjustment when
first installing the HE360B. Set the frost factor dial to 5 and
use Table 2 to adjust the frost factor, one setting at a time,
increasing the dial setting for more humidity, or reducing
the setting if moisture starts to build up on the inside of
your windows. Allow two days between adjustments to
determine if further adjustment is necessary. Once the
frost factor has been set, no further adjustment is needed.
23(5$7,21
The HE360A,B Humidifiers use the principle that vapor
(evaporated water) is created when warm dry air blows
over a water-soaked area. As the vapor circulates, the
relative humidity rises.
The humidity control monitors the relative humidity and
activates the humidifier accordingly. The humidifier has a
water supply that disburses water over a humidifier pad.
The warm dry air from the furnace passes over the
humidifier pad, collects moisture, and circulates it through
the house.
Since humidified air feels warmer and more comfortable,
the homeowner may decide to lower the thermostat
setpoint, thus saving money on heating bills. The end
result is that the humidifier provides a more comfortable
environment that is also energy efficient.

A regular maintenance program prolongs the life of the
humidifier and provides a more comfortable environment.
Frequency of cleanings depends on water conditions.
Either hard or soft water can be used in the humidifier, but
hard water mineral deposits are more difficult to clean then
soft water deposits.
Use the following procedure to clean the humidifier.
CAUTION
Personal Injury or Equipment Hazard.
Power Supply can cause electrical shock or
equipment damage.
Disconnect power supply before performing
humidifier maintenance.

Refer to Table 3 for troubleshooting procedures.
Table 3. Troubleshooting Procedures.
Problem What To Look For What To Do
Low humidity Furnace blower not operating. • Reset circuit breaker or check for blown fuse.
• Check that the furnace power is on.
• Check all external wiring connections.
• Check the humidity control setting.
• Call a professional heating contractor.
Rapid air changes. Drafts (cold air is dry and is an
added load to the humidifier). • Keep doors and windows closed. • Close fireplace damper when not in use.
• Keep exhaust fan running time to a minimum.
• Seal around doors and windows.
High humidity Condensation on walls. • Turn off humidity control and water until condensation
is completely evaporated.
Heavy condensation on windows. • Turn humidity control down low enough to eliminate
condensation caused by moisture from bathing,
mopping, cooking, etc. If moisture persists, more
ventilation is needed.
