INSTALLER: PLEASE FILL OUT AND MAIL GUARANTEE CARD AFTER INSTALLATION IS COMPLETE. LEAVE INSTALLATION INSTRUCTIONS WITH HOME OWNER

PRECAUTION: The installer should be an experienced service technician. Disconnect electrical power before beginning installation. Do not install where temperatures fall below 32 degrees F or where plenum temperatures exceed 200 degrees F. When wiring into a multi-speed blower circuit see Step 7D.

INSTALLATION: The humidifier may be mounted with the 6" outlet to the right or left by reversing the position of the Bypass Cover. The humidifier may be mounted on the warm or return air plenum with equal efficiency. See Typical Installations below.

ADDITIONAL MATERIALS THAT MAY BE NESSESARY:

1. 1/4" diameter copper or plastic water supply tubing (G.F. #747-38 suggested)

2. 5/8" diameter drain tubing (G.F. #1099-16 suggested)

3. 3/4" O.D. drain tube clamp (G.F. #P-163 suggested)

4. 6" diameter galvanized by-pass pipe

5. 6" diameter galvanized elbow

6. 6" diameter galvanized damper

7. 6" diameter collar

8. wire, two-conductor #18 or heavier (G.F. #727-48 suggested)

9. transformer 120V, 60HZ primary 24V, 10VA or greater secondary (G.F. #727-58 suggested)

10. air pressure switch (G.F. Model #12500 suggested)

INITIAL MOUNTING HOLE

CENTERLINE

Select location on vertical surface of warm or return air plenum for mounting humidifier and tape mounting template. Make sure the template is level. Do not install humidifier or 6" bypass pipe where the blanked off ends of a cooling coil will restrict air flow to the humidifier. Extend horizontal centerline from template to the adjacent plenum. Scribe 6” circle 10” to 15” from side of humidifier, on cabinet centerline.

CUT TEMPLATE ALONG THIS LINE CUT TEMPLATE ALONG THIS LINE

INITIAL MOUNTING HOLE

Start the three initial mounting screws. Mount humidifier cabinet in level position and tighten screws. Install six additional screws at top and sides of cabinet.

COPPER TUBING

PLASTIC TUBING

Cut 6” hole and install connecting collar, 6” elbow and by-pass pipe (not supplied). USE UNCRIMPED END IN HUMIDIFIER CABINET. Connect by-pass pipe to collar and humidifier cabinet. Using holes at top and bottom of humidifier bypass opening, screw by-pass pipe to humidifier cabinet. Install bypass cover by placing the tab of the bypass cover marked "TOP" behind the top flange of the humidifier cabinet, push up on the bottom clip until it clears the opening of the humidifier cabinet then push in on the bottom of the bypass cover.

NOTE: If furnace is used for summer cooling, install inline damper in by-pass pipe.

Mount the self tapping saddle valve on either a cold or a hot water pipe. A side or top mount is best to avoid clogging from pipe sediment. Connect 1/4” O.D. tubing to the saddle valve. Copper tubing requires a brass compression nut and brass sleeve. Plastic tubing requires a brass insert inside the tubing, a plastic sleeve on the outside with a brass compression nut.

NOTE: DO NOT USE PLASTIC TUBING ON HOT WATER OR IN CONTACT WITH ANY HOT PLENUM SURFACE OR DUCT. INSTALLATION OF THIS SADDLE VALVE MUST MEET OR EXCEED LOCAL CODES AND ORDINANCES.

SADDLE VALVE INSTALLATION INSTRUCTIONS

Copper Pipe

1. Retract piercing pin into valve body by turning handle counterclockwise.

2. Screw valve body into upper bracket and tighten.

3. Place rubber gasket over piercing pin.

4. Assemble saddle valve over copper pipe using enclosed screws, nuts and lower bracket.

5. Tighten screws evenly and firmly. Brackets should be parallel.

6. Complete compression connection to saddle valve outlet.

7. Turn handle clockwise to pierce tubing and close saddle valve.

8. Turn handle counterclockwise to open saddle valve, leave open for several seconds to flush dirt from pipe and tubing.

Steel, Brass or Hard Plastic Pipe

1. Shut off water supply and drain pipe.

2. Turn handle clockwise to expose piercing pin and close saddle valve.

3. Place rubber gasket over piercing pin.

4. Drill 1/8" hole in pipe using a hand crank drill to avoid shock hazard.

5. Assemble saddle valve over steel, brass or hard plastic pipe using enclosed screws, nuts and lower bracket.

6. Tighten screws evenly and firmly. Brackets should be parallel.

7. Complete compression connection to saddle valve outlet.

8. Turn handle counterclockwise to open saddle valve, leave open for several seconds to flush dirt from pipe and tubing.

Threaded Pipe Fittings

1. Turn handle clockwise to expose piercing pin and close saddle valve.

2. Seal valve body threads using pipe tape or sealant.

3. Install valve into 1/8" NPT fitting.

4. Complete compression connection to saddle valve outlet.

5. Turn handle counterclockwise to open saddle valve, leave open for several seconds to flush dirt from pipe and tubing.

COPPER TUBING

PLASTIC TUBING

Attach solenoid valve into top of humidifier cover using 1/4 turn rotation. If using copper tube, leave two coils of tube next to cabinet to allow cover movement for changing pad. If using plastic tube, anchor tube 2 inches below humidifier and leave some slack. This will allow full cover

movement. Loosen the fitting nut on the solenoid valve 1/2 turn. Push the 1/4" O.D.

tubing straight into fitting until it bottoms on the fitting's shoulder. TIGHTEN NUT BY HAND. Additional tightening is not required.

DO NOT OVERTIGHTEN NUT AS THE THREADS WILL STRIP AND THE FITTING WILL NOT FUNCTION PROPERLY. NOT USE PLASTIC TUBING IN CONTACT WITH ANY HOT PLENUM SURFACE OR DUCT.

HAUTTOP

DUCT HUMIDISTAT FLUSH

MOUNTING TEMPLATE

1. REMOVE ADHESIVE BACKING AND APPLY TO THE DUCT IN THE SELECTED LOCATION.

2. ACCURATELY CENTER PUNCH ALL HOLES.

3. DRILL FOUR MOUNTING HOLES SIZE 3/32", DRILL NO. 42 OR 2 mm.

4. DRILL OTHER HOLES WITH 1/8" OR 3 mm DRILL.

5. BREAK METAL FROM GROUP OF HOLES, AND CUT OUT ON SOLID LINE WITH SHEARS.

MOUNTING ON THE RETURN AIR DUCT

Do not install the humidistat on the warm air duct.

1. Locate the humidistat at least 24" upstream of the humidifier or bypass on the return air duct. Avoid areas of direct radiation like secondary heat exchangers in the fan compartment.

2. Place template using level. Cut sensor hole as shown on template. Drill four 3/32” holes as shown.

3. Remove the housing from the base by prying with a small screwdriver at the notch in the side of the housing.

4. Place the outer part of the foam gasket on the humidistat base and mount the base with four screws. Low voltage wire may enter the humidistat under the foam seal.

5. Connect wires to screw terminals on the control assembly as shown in wiring diagram. Replace housing.

WALL MOUNTING INSTRUCTIONS

1. Chose a location for the humidistat about five feet above the floor on an inside wall with average room temperature and humidity conditions.

2. Drill a small hole in the wall and run low voltage wiring to the location chosen. Pull about 6” of wire through the hole. Plug the opening to prevent drafts from affecting the humidistat operation.

3. Remove the housing from the base by prying with a small screwdriver at the notch in the side of the housing.

4. Mount the base horizontally over the wires using level. Attach directly to the wall, using four screws provided.

5. Connect wires to screw terminals on the control assembly as shown in wiring diagram. Replace housing.
