d. Insert the tubing into the saddle valve fitting and support the valve while

tightening the compression nut.

e. Insert plastic supply tubing into quick connect fitting. Insert fully, and apply

modest pull pressure to ensure a tight fit.

4. Use the following steps to install a

1/2 in. (13 mm) drain tube between the

humidifier and the floor drain (see Fig. 10).

a. Slide the drain clamp over the tubing.
b. Push the tubing over the drain nipple

on the humidifier.

c. Hand-tighten the clamp around the

tubing to secure it to the humidifier

drain. The clamp is tightened by com-

pressing the two sides together so

that one side fits into the ridged grove

on the other side.

d. Secure the tubing (can use foil tape)

along the route to prevent movement

and ensure downward slope for cor-

rect drainage.

NOTE: Cut tubing to correct length so the tubing terminates at the drain.

Connecting the Pressure Switch

1. If the humidifier is installed on

the supply duct (as is recom-

mended), the pressure switch

needs to have the tubing fed to

the return duct. If the humidifier

is installed on the return duct,

the pressure switch needs to

have the tubing fed to the supply

duct.

2. Drill a 3/4-in. (19 mm) diameter

hole in the duct within 10 ft.

(3 m) of the switch to ensure the

provided tubing reaches the

pressure tap elbow.
