Air King 6000 Installation & Operating Instructions Manual page 3

1. The humidifier body and bypass tube are installed at eye level, easily accessible for
installation and routine maintenance.
2. The space between the humidifier body and bypass tube are no more than 30" to ensure
maximum air flow through the humidifier.
3. The aluminum flex bypass tube are cut to the proper length and pulled tight to ensure
maximum air flow.
4. The bypass damper is fully open.
5. The humidifier is mounted level on the duct.
6. There is nothing inside the duct behind the bypass collar and damper or the humidifier body.
7. The humidifier and bypass collar and damper are level.

Figure 2
1. The humidifier body is installed too low and will be difficult to work on.
2. The humidifier body and bypass collar and damper are not level. This will restrict air-flow
through the humidifier as well as create uneven air-flow over the evaporator pad and
activating sensor.
3. The bypass damper is not fully open, This will restrict air flow through the humidifier and
reduce output.
4. The humidifier is being drained to a bucket rather than a proper drain. This will result in
damage to the home.

2. The aluminum flex bypass tube is not cut to length and is sagging. This will result in reduced
air-flow over the evaporator pad and will affect the performance of the activating sensors.

Figure 4
1. The bypass collar and damper are installed in front of the furnace's air-conditioning coils.
This will not only greatly affect the performance of the humidifier and cause malfunctions
in the activating sensors, the homeowner risked damaging the air-conditioning coils. This
would also be the case if the humidifier were installed in front of the air-conditioning coils.
INSTALLATION TIP: In this type of installation the installer should mount the bypass collar and
damper at least 6" above the air-conditioning coils and use hard metal ducting and elbows
(sold separately) rather than the flex tube. While the humidifier and bypass collar and damper
will not be level the use of hard ducting rather than the flex ducting will make up for any
restrictions or turbulence which would occur in aluminum flex tube.

Figure 5
1. The bypass collar and damper and the humidifier body are installed on the same ducting.
This unit will not operate at all, there will be no air-flow through the unit, the air pressure
will just equalize. This will be the case if both components are mounted on the return or on
the supply duct.
