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.
