can be sensed.
Once the sensor is installed you can replace the humidistat front
cover, position the automatic humidistat label, and replace the
knob.

INSTALLATION.
1. The unit is supplied with a 24 Volt plug in transformer. The
transformer wires have 2 insulated female push on terminals.
Connect these terminals to the humidifier side panel to the male
terminals marked 24 Volt IN. At this time check that the solenoid
valve wires are connected to the terminals marked 24 Volt OUT.
(fig 28)
2. Once the water and electrical connections are made to the
humidifier side panel you can install the bypass tube. Install the
bypass tube on the bypass collar first.
Figure 28
Slide one of the 6" spring clamps over
one end of the aluminum flex tube,
slide this end of the aluminum flex
over the flange on the bypass collar
and secure in place with the spring
clamp.
3. Slide the other 6" spring clamp over
the other end of the aluminum flex,
then slide this end of the aluminum
flex over the humidifier's side and
secure in place with the spring clamp.
4. Make sure the spring clamp is not
touching the solenoid valve or it may
cause buzzing, as well check that the aluminum flex bypass is
pulled tight and is not sagging. You may cut some length off if
necessary.
Installation is now complete and you may test the unit.
STEP #7 – TESTING THE UNIT.
If you have not already done so replace the humidifiers front
cover and secure in place with the supplied thumb screw. Plug
the 24 Volt transformer into a constant 120 volt outlet (one that
cannot be shut off). Turn on the water, and the power to your
furnace. Do the following to test the unit.
1. Whether in Manual or Automatic operation the humidistat has
a TEST setting, turn the dial all the way to the right to the TEST
indication.

Model 7000 Flow Through Humidifier
2. Turn UP your furnace thermostat so the furnace will cycle on
and blow hot air
•OPERATING TIP: Most furnaces will take a few minutes
to allow heat to build up before the furnace fan will run.
The "HUMIDISENSE" control will wait until it senses your
furnace fan blowing hot air. If only your furnace fan is
running the unit should not turn on. The "HUMIDISENSE"
control will not turn on the humidifier until it senses a
temperature rise of 4˚C and the air temperature is over
30˚C. This ensures efficient use of water.
3. Depending on your furnace type the unit should turn on
within approx 60 seconds of the furnace entering the heating
cycle. You will know the humidifier is operating because the
Green LED on the front of the side panel (fig 29) will turn ON.
4. In TEST setting the humidifier will run approx 1 min and shut
OFF regardless of the Furnace still heating and blowing hot air.

highest setting (Automatic Operation - Setting #7 / Manual
Operation – Setting 45%) then turn up your furnace
thermostat and allow the furnace to turn ON again.
7. The humidifier should turn back on and continue to run.
During this running test check for and repair any leaks. Let the
unit run 3 to 5 minutes and then turn your furnace thermostat
down. IT IS IMPORTANT TO ALLOW THE FURNACE TO
CYCLE OFF VIA THE THERMOSTAT AND NOT THE MAIN
FURNACE SWITCH, AS ALL FURNACES WILL RUN A COOL
DOWN TO ALLOW HEAT TO CIRCULATE OUT OF THE
FURNACE HEATING CHAMBER. The humidifier will sense
the temperature drop and shut off (this will occur depending
on your furnace, from 60 seconds before the furnace shuts off
to 60 seconds after the furnace shuts off.) You will know the
humidifier has shut off because the green LED on the front of
the side panel (fig 29) will shut OFF
•OPERATING TIP: Most furnaces will take anywhere
from 30 sec. to 2 minutes to complete the OFF cycle.
First the furnace will sense that the thermostat is satisfied
then the furnace burner will shut off. The furnace fan
will continue to run (the amount of time depending on
how your furnace is set up) this allows the heat to
circulate out of the furnace heating chamber and assures
efficient use of heating fuel.
8. Testing is now complete please review the Humidifier Operation
section of the instructions & the Warranty/Maintenance/& Trouble
Shooting Guide. Read and save both manuals.

5. Once the humidifier
has shut off, turn down
your furnace thermostat
and allow the furnace to
shut off and cool down for
a minute or two.
6. After the furnace has
cooled down take the
humidistat out the TEST
setting and set it to the
