the upper edge of the humidifier against the duct so that the
mounting holes line up with the drilled holes on the duct.
Secure the humidifier with two #8 X 3/4” self-drilling sheet
metal screws from the accessory bag.
6. Refer to the section regarding pad replacement on page 8.
Complete that section before proceeding to ensure that the
internal components of the humidifier 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 humidifier 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
improper 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 humidifier supply fitting, turn the
saddle valve to the open position and discharge the water
into a bucket or pan. This will allow the water to flush
any debris that may have accumulated in the line during
the installation process. Once this is complete, close the
saddle valve.
3.
Attach the line to the humidifier by simply pushing the line
into the push-to-lock fitting 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
fitting to release the line and pull it out. See Figure 5 for
plumbing diagram.
4.
Connect the drain hose to the drain connection fitting 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 fittings
before proceeding.
4.4 Electrical
The ComfortBREEZE
CB300/CB300S humidifier requires a 24
VAC source of electrical power that may be taken from the HVAC
system terminals. In order to access the wiring compartment
press the release pads, as shown in Figure 6, and pull the cover
off toward you.

Refer to Figure 7. Install the 24 Volt transformer from a source
of 120VAC power that is only powered when the furnace fan
is energized. The transformer will supply 24 VAC through the
humidistat and air proving switch (not included) and energize
the water solenoid valve upon a call-for-humidity.
