2. Drill three marked bypass collar mounting holes on the
template using a 1/8" drill bit (not supplied)
3. Using a 3/8" drill by (not supplied) drill a hole inside the
circular area marked collar cut out.
4. Using the 3/8" hole drilled in step 3 as a starting point cut out
the Collar Cut Out area marked on the template using tin snips
(not supplied)
5. Mount the bypass collar and damper (fig. 12) using the
remaining three screws from the installation package. The air
damper should be mounted in the open position. The top

6. Slide one of the 6" spring clamps supplied over one end of the
bypass tube. Slide this same end of the bypass tube over the
flange of the collar and secure it with the spring clamp.
7. Slide the other 6" spring clamp over the other end of the
bypass tube. Slide this end of the bypass tube onto the
humidifier and secure it with the spring clamp.
8. Ensure the bypass is pulled tight and that any ripples are kept
to a minimum and no sagging is occurring. Cut any excess
bypass tube off if necessary using tin snips (not supplied).
• INSTALLATION TIP: If replacing an existing humidifier
which has been installed on your furnace you may be
able to use the existing cut-outs, however replace the
components, bypass collar and damper and bypass
tubing. The majority of furnace humidifiers use 6"
ducting for bypass. The cutout for the humidifier will
more than likely be different. If replacing a drum style
the cutout will not be big enough, and if replacing an old
flow through you may have to first install a separate
metal plate (not supplied) to cover the existing hole as it
may be too big. Before you mount the separate metal
plate (not supplied) attach the humidifier cabinet
template to it and drill all necessary holes and make the
required cutouts. Keep in mind the points listed above
about length and level of ducting; it maybe best to cover
all existing holes and start fresh.
STEP #4: WATER SUPPLY AND DRAINAGE CONNECTION
WARNING: Make sure the evaporator pad is installed correctly
BEFORE you make the water connections.
1. SAND BOTH ENDS (fig 13) of the water supply tube. FAILURE
TO DO SO MAY RESULT IN LEAKS.

4. Select the most convenient location for connecting the self-
piercing needle valve on a cold water pipe. Connect the needle
valve as shown (fig 16). The hardware shown is supplied in the
needle-valve kit. Once the the valve is connected to a pipe as
shown, TURN THE VALVE CLOSED ALL THE WAY, and then
open so water can flow to the humidifier. Check all fittings for
leaks and tighten/repair if necessary.
