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 tubing into the solenoid valve fitting. 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 Total Comfort System HE360A Humidifier is controlled by
the H8908 Humidistat. The humidistat 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. Table 1 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.
OPERATION
The HE360A 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.
Table 1. Recommended Humidity Control Settings.
MAINTENANCE
A regular maintenance program prolongs the life of the
humidifier and provides a more comfortable environment.
Cleaning frequency 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.
IMPORTANT
Never oil any part of the humidifier.
