3. Introduction
The benets of a properly humidied environment (35-50%
Relative Humidity) are many. They include both personal com-
fort as well as the preservation of furniture, draperies, carpets,
wooden oors and cabinets, paintings, pianos, etc. Your home
can be more comfortable at a lower temperature (i.e.: 68° F)
at 30-40% Relative Humidity (RH) than at 71° to 72° F with-
out controlled humidity. Since every degree of temperature
setback represents about 3% of your heating costs, this can
possibly represent a signicant annual savings. During the heating season, cold air inltrates the home and must be heated.
When heated, this air dries out and greatly increases its
capacity to hold more moisture. By using a humidier, a
source of water is provided to satisfy this increased mois-
ture holding capability, rather than having it drawn from our
body surface and the surrounding furnishings in the home.
3.1 Basic Operation
Your Comfort
operates on the principles of evaporation. Water is introduced
to an evaporator pad as warm air from the duct is circuilated
through the pad. The warm air evaporates the water and the relative humidity of the air increases. Any excess water is passed
to the drain. CB300S units are equipped with a ComfortSmart
controller which acts to minimize the amount of water that may
ow to the drain by adjusting the total water ow to the humidier.
Setting the humidistat in the recommended range of 30-40%
relative humidity assures automatic humidity control during the
heating season. A lower setting may be necessary to prevent
condensation on windows during the coldest part of the winter.
An electronic humidistat is supplied with CB300S units that can
automatically adjust the setpoint as the outdoor temperature
falls.
Minimal action is needed to turn the humidier off for the summer months. Simply rotate the damper to the closed position
and lower the humidistat setpoint.

4.2 Mounting
The ComfortBREEZE CB300/CB300S humidier may be
mounted directly to the warm air supply duct or the return duct
of your HVAC system. Certain conditions must be met to ensure proper unit operation. Refer to the following list.
• Ensure that the duct surface is reinforced, if necessary, to
allow the unit to remain level and plumb.
• Ensure that the humidier has adequate clearance to allow
for the removal and replacement of the evaporator pad.
• When installing the humidier in an attic or above a ceiling,
a drain tray must be installed under the unit as a precau-
tionary measure to prevent water damage from occuring if
a leak develops.
• The recommended humidistat range is 30-40% relative humidity. If condensation occurs on windows, the humidistat

setting must be lowered to prevent condensation damage.
• DO NOT install the humidier where freezing temperatures
may occur.
• DO NOT install the humidier where it interferes with the
furnace access panels.
• DO NOT install the humidier close to a ue pipe. Intense
heat may damage the humidier.
• DO NOT mount the humidier in the jacket of a cased
coil. It is preferable to mount the humidier immediately
downstream of the cased coil, if present. Ensure that the
humidier does not interfere with the coil ends.
• DO NOT mount the humidier in a furnace jacket.
• DO NOT install on gravity hot air systems.
• DO NOT connect a hot water supply to ComfortBreeze

6. Refer to the section regarding pad replacement on page
8. Complete that section before proceeding to ensure
that the internal components of the humidier are properly
aligned/installed as they may have become misaligned
during shipment. Failure to complete this task may
result in faulty operation or leaks.
7. Ensure that the humidier is level and plumb before proceeding.
4.3 Plumbing
1. Install a saddle valve and strainer (not provided) on the
nearest cold water supply pipe. Hot water will cause im-proper operation. (See the instructions that accompany
the saddle valve for additional details).
2. After the saddle valve and strainer are installed but before
inserting the line into the humidier supply tting, turn the
saddle valve to the open position and discharge the water
into a bucket or pan. This will allow the water to ush any
debris that may have accumulated in the line during the in-
stallation process. Once this is complete, close the saddle
valve.
3. Attach the line to the humidier by simply pushing the line
into the push-to-lock tting and pulling back slightly to seat
the line. If it becomes necessary to remove the line, press
on the release ring around where the line goes into the t-
ting to release the line and pull it out. See Figure 5 for
plumbing diagram.
4. Connect the drain hose to the drain connection tting and
run this to an open, gravity drain. The end of this line must
not be submerged in water or be trapped.
5. Turn on the saddle valve.
6. Ensure that no water is leaking from any of the ttings before proceeding.

may occur and will be displayed by the LED’s.
1. Rapid Red Blink = Terminals AP1 & AP2 for the air proving
switch did not close. The unit will not operate until airow
is present.
2. Slow Red Blink = Once the solenoid valve is energized and
humidication has begun, the controls must see a change
in termperature or the unit will not be allowed to operate.
This may be an indication of interupted water supply.
3. Alternating Red/Green Blink = One of the thermistors has
failed.
• If T1 has failed the LED will blink Green/Red/Red with a
two second delay. The unit will not operate in this con-
dition unless DIP switch #5 is turned ON and the reset
button is pressed.
• If T2 has failed the LED with blink Green/Green/Red with
a two second delay. The unit will not operate in this condition unless the T1 thermistor is relocated to act as T2
and DIP switch #5 is turned ON. Using the override DIP
switch is only recommended as a temporary solution until
the failed thermistor can be replaced.
