PLUMBING

CAUTION
Chemical Hazard.
Can cause damage to environment or air
conditioning system.
Do not use any refrigerant line connected to an air
conditioner.
NOTE: Use either hard or soft water in the water treatment
system.
IMPORTANT
Use only copper tubing to plumb from the humidifier
to the water treatment system.
1. Locate the cold water pipe closest to water treatment
system.
2. Plumb between the saddle valve (provided) and the
solenoid on the water treatment system. See Fig. 11.
3. Use the saddle valve instructions to install the valve
(provided).
The valve is self-piercing when installed on copper pipe.
IMPORTANT
— Position the valve so water flows from the top or side
to reduce the chance of clogging the valve with
minerals.
— Lightly clean the copper tubing ends with fine
sandpaper before making any connections.
4. Run 1/2 in. (12.7 mm) ID drain line from barbed fitting
on water treatment system to floor drain.
5. Run 1/4 in. (6.35 mm) OD copper tubing from water
treatment system to humidifier.
IMPORTANT
Do not overtighten the compression nut. Moderate
tightness prevents leaking.

CHECKING INSTALLATION
After installation is complete, use the following procedure to
check humidifier operation:
1. Turn on the humidifier water supply.
2. Plug in the humidifier and check that the humidifier has
power. Wait a few minutes for the reservoir to fill.
3. Turn the Convertible Humidity Control to the highest
setting.
4. Check that the furnace blower comes on to circulate the
moist air. The blower may take as long as fifteen min-
utes to turn on.
5. Reset the Convertible Humidity Control to a comfortable
setting.

OPERATION

The HE440A, HE480A Humidifiers are controlled by the
Convertible Humidity Control that is installed either on the
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 your
humidity control.
— Match the dial setting to the outdoor temperature to
optimize the humidity level while reducing the moisture
condensation on your windows.
— Use Table 2 to adjust the humidity control to the
recommended setting.
NOTE: As the outside temperature drops, lower the recom-
mended setting to accommodate the effects of dew-
point. 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.
NOTE: If this condition persists for more than a few hours,
set the humidity control to the lowest setting to turn
off the humidifier. If the condition does not improve,
ventilate the house to remove the moisture.
