HARDWIRE TRANSFORMER INSTALLATION
1. Consult your furnace's installation manual and or an HVAC professional, locate the furnace's
control board normally found in the bottom portion of the furnace near the furnace blower.
2. Identify the furnace's accessory terminals. There will be one set of terminals marked
"NEUTRALS" and another set will be marked HOT, HUM, EAC.
3. If you are unsure consult your furnace's installation instructions and or an HVAC professional.
4. Retrieve the hardwire transformer, at the bottom of the furnace locate an unused electrical
knockout, remove the knockout and install and secure the transformer in the knockout. Attach
the transformer so the low voltage 24 volt terminals are located on the outside of the furnace.
5. Using the black & white TEW 18 gauge wire and ¼" electrical terminals connect the white
wire to one of the "NEUTRAL" terminals on the furnace board. Then connect the black wire
to the 120 Volt HUM terminal on the furnace board.
6. Using the wire nuts and electrical tape connect the white & black wires installed in step 5 to
the two transformer wires, secure the wire nuts with the electrical tape.
7. At the humidifier, your installation should be as per the installation instructions with the plug
in transformer wired to the two terminals marked 24 VAC IN on the humidifier's side panel
with the humidistat wired into one of the transformer wires.
8. Retrieve the plug in transformer and cut the wire off at the transformer body. Separate the
wires and strip the ends of the wire. Attach the ends of this wire to the 24 Volt terminals on
the hardwired transformer installed in steps 5 & 6 above.
9. At the humidifier, change all the DIP switches to the ON position and install a jumper wire
across humidisense bypass terminals #3 & #4.
TROUBLE SHOOTING
Humidifier seems to operate properly, green humidisense LED comes ON when furnace
is in heating and the humidistat is calling for humidity but no water flows or very little
water flows.
This is an indication that there is something wrong with the water supply or there is some sort of
blockage in the orifice fitting, inlet water filter or the solenoid valve. Follow the directions below to
check the water supply and inspect the orifice fitting & inlet water filter and clear any blockage.

NOTE: Before replacing the solenoid valve which is an expensive component complete a quick
test below to ensure the problem is not the voltage supply from the humidity control. Follow the
directions below.

Solenoid Valve Quick Test (Figure 9). (Connect the plug in transformer directly to the solenoid
valve to see if the valve will open and let water flow.)
1. Unplug the transformer.

Filter
In Canada homes built since the year 2000 are designed to reduce moisture to protect against
condensation damage this is accomplished by introducing fresh outdoor air into the home
most often through the forced air heating system return duct. If you are seeing consistently low
humidity readings after several weeks of operation consider moving the humidity control from
the current location. On Model 5000 you can try locating the humidistat in another location on
the duct or in the living space. On model 6000 you can purchase a remote sensor with 25 ft
of wire (PN 010266001) to locate the sensor elsewhere in the duct or living space. An optional

is a very small pin sized hole in this fitting, if it is blocked try to clear it using a pin or
other method. DO NOT drill this hole larger the purpose of the orifice is to protect against
water blowing off the evaporator pad into the furnace as well as to limit the amount of
