Connecting the Plumbing
1. Shut off the water.
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. First, connect 1/4-in. line to the humidifier's sole-
noid valve, located at the bottom of the humidifier.
a. Remove the compression nut.
b. Discard the brass ring, replacing it with the plas-
tic ring.
c. Install the brass insert into the end of the tubing.
d. Insert the tubing into the solenoid valve fitting
and support the valve while tightening the com-
pression nut.
NOTE: Do not over-tighten the compression nut. Moder-
ate tightness prevents leaking.
3. Use the 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.
