Installation
WATER SUPPLY
1. Water for the humidifier must be taken from a nearby cold water line.
Turn off the water supply. Drain by opening a faucet at a lower level of the
line.
2. Mount the saddle valve on the water line as close to the humidifier as
possible. You have been supplied with (10) feet of 1/4" plastic tubing.
SPECIAL NOTE: When measuring the distance from the saddle valve location to
the humidifier, keep in mind that the tubing must be supported; therefore,
it must run along ceiling and walls. measure along the path the tubing will
follow.
3. Back out the piercing pin by turning the 'T' handle counter clockwise
and then clamp the saddle valve body securely on the water line with rubber
gasket positioned as shown (Fig. 13). On galvanized or copper pipe over 5/8",
first drill a 5/42" hole.

CAUTION: For safety use a hand drill or grounded electric drill.
4. Turn handle clockwise until it has pierced the water line and valve is
completely close (Fig.13).
5. Partially uncoil the tubing. Slide the brass compression nut over the
tubing. The thread in the nut must face the tubing end. Place the brass compression
sleeve as shown (Fig. 13). Slip brass insert into end of tubing.
6. Insert the tubing end into the saddle valve at threaded stem 'A' (Fig.
13) as far as it will go. Thread the brass compression nut onto the valve,
then tighten gently with a wrench. Take care not to over tighten the nut.
7. Unwind the rest of the tubing. Take care not to kink it. Run the tubing
along flat surfaces to the humidifier. SUpport the tubing as needed to avoid
contact with the furnace.
8. Close previously opened faucet. Turn on main water supply. Place a pail
under the end of the tubing. Open the saddle valve. Flush the line. Make sure
there are no leaks along the line or at the valve. Turn the valve off.
9. With water supply tubing cut to the proper length, slide the plastic compression
nut over the tubing. Slip brass insert into the end of tubing.
10. Insert the tubing end into the solenoid valve fitting as far as it will
go and hold it there, thread the plastic compression nut onto the fitting,
then tighten securely, finger tight (no wrench). Do not over tighten nut (Fig.
14).

11. Turn on water at supply saddle valve. Check for leaks at solenoid valve
fitting and plastic compression nut.
NOTE: water will not flow through humidifier unit until electrical installation
is complete.
