Use hot or cold water and either hard or softened water
in the humidifier.

CAUTION
Chemical Hazard.
Can cause personal injury or equipment
damage.
Do not use any line connected to an air
conditioner.
Do not use gas line.
2. Use the self-piercing saddle valve (included) to tap
into the water supply line at the location selected.
See Fig. 8. If tapping into galvanized pipe, drain
line and pre-drill 3/17 in. tap for 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 han-
dle pointing toward the ceiling.

dle 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. Install brass insert into end of tubing.
c. Slide the plastic compression ring over the
tubing. (Discard copper compression ring pro-
vided with valve.)

rings with plastic tubing. Use copper sleeve
rings only with copper tubing.

and support the valve while tightening the com-
pression nut.
NOTE: Do not over-tighten the compression nut. Mod-
erate tightness prevents leaking.
