HE240, HE280 HUMIDIFIER AND INSTALLATION KIT

Connecting the Plumbing
Use hot or cold water and either hard or softened water in the humidifier.
NOTE: Using hot water will increase operating costs, but may provide a small
increase in the amount of humidity delivered.
IMPORTANT
Please consult local plumbing code for proper plumbing regulations before
beginning. Use of a manual shutoff valve may be required to meet code in your area.
1. Shut off the water.
2. Use the self-piercing saddle valve
(included) to tap into the water supply
line at the location selected. Turn the
handle on the top of the saddle valve to
the right (clockwise) until the needle
pierces the water supply line. Leave the
needle in this position until the
humidifier is fully installed to prevent
leaking (even though the water supply
is turned off, there can still be water in
the line that will leak as soon as the
needle is backed out). See Fig. 8. If
tapping into galvanized pipe, drain the
line and pre-drill 3/16 in. tap for the
saddle valve.
Fig. 8. Installing the saddle valve.
NOTE: The saddle valve is not designed to regulate water flow. The valve is
either open or closed.
IMPORTANT
To prevent debris from clogging the solenoid in-line filter, be sure to install the
saddle valve handle pointing toward the ceiling.
3. Use 1/4 in. (6 mm) OD tubing and
connect the saddle valve to the
inlet side of the solenoid valve on
the humidifier (see Fig. 9).
a. Place the brass compression nut
over the tubing.
b. Slide the plastic compression
ring over the tubing. (Discard
copper compression ring
provided with valve.)
c. Install brass insert into end of
tubing.

NOTE: To prevent leaking, use plastic (Delrin) compression rings with plastic
tubing. Use copper sleeve rings only with copper tubing.
