3 Product Description
Condair RE Product Description |9
3.1 General Description
The Condair HumiLife RE bypass humidifier uses the pressure difference between the supply air from
your furnace and the return air into your home. This pressure difference forces air through the humidifier
thereby increasing the humidity of the air leaving the unit. This allows the humidifier to consume very
little energy to improve the comfort of your home.
The Condair RE package comes with:
lCondair RE complete with ceramic media.
lInstallation components such as power supply, saddle valve, supply water hose (with quick
connect adapter), drain hose, and associated hardware.

3.2 Functional Description
The Condair HumiLife RE is a bypass humidifier that attaches to the duct of the furnace ventilation
system. It may be installed on either the supply duct or on the return duct. A small opening is created in
the duct where some of the furnace air is directed through the Condair HumiLife RE. Water vapor
leaving the unit then re-enters the duct where it mixes with the rest of the furnace air, before a fan
directs the air into your home.
This solution relies on the pressure differential provided by the furnace fan. The humidifier will achieve
increased efficiency when the furnace is in heating mode.

By installing a bypass duct between the supply and return air, a small amount of warm air passes over a
wet ceramic media in the humidifier. The warm air evaporates the water, and water vapor exits the
humidifier at a downstream location in the return duct.
When there is a humidification requirement from an external signal, the solenoid valve in the unit
activates and allows water to run through the ceramic media. When humidity reaches the setpoint, the
solenoid valve turns off, shutting off the water supply. This process repeats as needed to maintain the
humidity around the setpoint.

Figure 8 - Mounting Procedure
To mount the humidifier:
1. Use the templates (supplied) to cut holes in the ducts.
a. Position the rectangle mounting template on the air duct. Ensure the template is level and
in the desired position.
b. Ensure that the humidifier will have the proper clearance.
c. Cut a rectangle into the air duct (return or supply). This hole will be for the humidifier body.
Width x Height: 9.45 x 12 in (240 x 305 mm)
d. From the center of the rectangle, draw a horizontal line towards the adjacent duct (return or
supply). Use the horizontal line as a rough guide. Align the center of the circle (of the circle
mounting template) on the adjacent duct, then place the template on the duct.
e. Cut a round hole into the other duct. This hole will be for the bypass duct.
Diameter: 6 in (152 mm)
2. (Optional) Change the orientation of the bypass opening (ex. from the left side opening to the
right). Required if the orientation of the humidifier does not fit with the current configuration of
your air ducts.
a. Remove the top cover, then the bottom cover of the humidifier. This will allow you to
access the tabs on the end caps of the bypass.
b. Push in the tabs on the bypass opening and the opposite end cap, and push out the end
cap and bypass opening. Switch their positions.
c. Reinstall the bypass opening/damper and end cap, then reinstall the bottom cover.
3. Mount the humidifier.
a. Remove the top cover from the humidifier.
b. Secure the support hooks on the humidifier to the bottom lip of the rectangular hole.
c. Push the top of the humidifier back against the duct and fasten the humidifier to the duct by
using two self-drilling sheet metal screws (provided).
d. Reinstall the top cover.

Figure 9 - Bypass Duct (not supplied) and Damper Switch
To install the bypass duct:
1. Adjust the bypass duct and fix it to the circular hole of the air duct. Typically, the bypass duct
should have tabs for the air duct that can be folded outwards.
2. Extend the free end of the bypass duct to the humidifier and secure with sheet metal tape.
3. Depending on the season, switch the damper pad on the humidifier. This must be done
manually every season.
lSUMMER - damper closes and air does not pass through the humidifier.
lWINTER - damper opens and air passes through the humidifier.

5.5.4 Connecting the Water Supply
Shut off the water supply before beginning.
To supply water to the humidifier:
1. Remove the protective sleeve on the inlet valve and install the white quick connector over the
inlet valve.
2. Measure and cut the water supply hose that will reach the humidifier from the water supply
valve.
lIf there is no spare line from the water supply, create one using a self-tapping saddle
valve (or install a T-fitting and valve). Refer to "Tapping into an Existing Water Line" on
the facing page. Consult local plumbing codes.
3. Insert the water supply hose into the quick connect fitting and ensure a tight fit.
4. Connect and tighten the water supply hose to the supply valve.
lPlastic hoses require brass tubing reinforcement. Use a plastic sleeve with a brass
compression nut.
lCopper tubes require a brass sleeve and brass compression nut.
5. Tighten the brass compression nut on the hose.
6. Turn the saddle valve counter-clockwise to allow water to enter the new line.
7. Check for leaks.
Figure 10 - Water Supply Connection

5.5.5 Tapping into an Existing Water Line
Note: You may also use a tee-fitting and shut-off valve from the existing water line. This may
require the use of a plumber.
Ensure the water supply is turned off.
The humidifier can use hot or cold water.

9. T-fitting valve and shut-off
IMPORTANT! Do not use the saddle valve to pierce plastic supply water pipes. Only rigid (copper
or steel) water lines can be used with the saddle valve. A T-fitting and shut-off valve must be used
with a plastic (or PEX) water supply line.
IMPORTANT! Ensure the piercing pin is completely backed up into the valve body by turning the
handle counter-clockwise.
IMPORTANT! Adhere to all local/national plumbing codes.
To tap into the water line (using the saddle valve on rigid pipe):
1. Loosely assemble one side of the top clamp to bottom clap with one screw and nut
(provided). For best results, mount the saddle valve on the top or side of the water supply
line. This prevents sediment from clogging the system.
2. Place the rubber gasket over the piercing pin of the top clamp, then place the gasket and
clamp over the water supply line.
3. Assemble the other side of the top and bottom clamps. The water supply line should be
pressed between the rubber gasket and bottom clamp.
4. Tighten the connection between the top and bottom clamps.
5. Connect the water line between the humidifier and saddle valve. Ensure the fittings (brass
nut, plastic sleeve, etc.) are installed.
lFor the plastic water line (supplied), from the saddle valve to the humidifier:
a. Place the brass compression nut over one end of the plastic water line. Ensure
the wider opening of the nut faces the saddle valve outlet.
b. Place the plastic sleeve over one end of the plastic water line.
c. Place the brass tubing reinforcement into the plastic water line.
Condair RE Installation and Planning |19

20 |Installation and Planning Condair RE
d. Insert the plastic water line into the saddle valve outlet. Push the brass
compression nut to the saddle valve, over the plastic sleeve, and over the brass
tubing reinforcement. The sleeve and reinforcement should be nested in the nut.
e. Secure the nut to the saddle valve.
f. Connect the other end of the plastic water line to the humidifier, at the inlet valve (or
quick connect, if installed)
6. Twist the handle on the saddle valve clockwise to pierce the water supply line. Twist counter-
clockwise to allow water through the saddle valve.
5.5.6 Connecting the Drain Line
To connect the drain line:
1. Connect the drain line to the spout on the humidifier and secure the hose with hose clamps.
2. Route the drain hose to a suitable drain. The hose must have a continuous downward slope (to
prevent standing water) and have no kinks. Suitable drains include:
lFloor drain
lSink
lSewer
3. Secure the hose along its length to prevent sagging.
