HE365A,B POWERED FLOW-THROUGH HUMIDIFIER
68-0243 6
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.
CHECKING INSTALLATION
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.
OPERATING HUMIDIFIER
The Enviracaire Elite HE365A Humidifier is controlled by the
H8908B 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 Enviracaire Elite HE365B 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 HE365B. 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.
OPERATION
The HE365A,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.
