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 inverting the cabinet and
reversing the positions of the distributor trough and drain	RETURN AIR	RETURN AIR
pan. The humidifier may be mounted on the warm or	WARM AIR
return air plenum with equal efficiency.
See Typical Installations.
ADDITIONAL MATERIALS THAT MAY BE NECESSARY:
1. 1/4" diameter plastic supply tubing or 1/4" copper
supply tubing for hot water applications
2. 6" diameter galvanized by-pass pipe
3. electrical wire and wire nuts

TEMPLATE FOR INSTALLING

BYPASS HUMIDIFIER

FOLLOW INSTRUCTIONS PACKED WITH HUMIDIFIER

1. REMOVE PROTECTIVE PAPER FROM BACK OF TEMPLATE AND STICK IN LEVEL POSITION. 2. CENTER PUNCH AND DRILL THE FOUR SIDE MOUNTING HOLES WITH A 1/8 " DIA. DRILL. 3. HANG HUMIDIFIER FROM FOUR SIDE SCREWS AND INSTALL DRAIN PAN, EVAPORATOR

PAD AND DISTRIBUTOR TROUGH.

WHEN INSTALLING ON BASEMENT TYPE FURNACE, EXTEND THIS LINE

FOR LOCATING HOLE ON ADJACENT PLENUM

4. TIGHTEN SCREWS AND ADJUST HUMIDIFIER UNTIL LEVEL.

5. REMARK FOUR REMAINING HOLES IF NECESSARY.

6. REMOVE HUMIDIFIER, DRILL REMAINING HOLES AND CUT OUT CENTER SECTION OF TEMPLATE.

CUT ON THIS LINE

TEMPLATE NO. 1042-25

IF FURNACE JACKET EXTENDS MORE THAN 3" OUTWARD FROM THE PLENUM SURFACE

ALLOW 4" CLEARANCE BELOW THIS LINE FOR EASY ACCESS TO DRAIN HOSE CONNECTION.

Select location on vertical surface of warm or return air plenum for mounting humidifier. For plenum sizes 9 1/2" to 15" use 1040AD adapter plate and five screws, 3 screws in top (supplied with DM model only). Stick mounting template in place making 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, using connecting collar as guide.

Cut out center section of template and 6” hole. Hang humidifier cabinet and insert remaining four screws. Tighten all 8 screws. Install connecting collar after drilling 1/8” holes for screws. Connect by-pass pipe to collar and humidifier cabinet. Using holes at top and bottom of humidifier bypass opening drill 2---1/8" holes through bypass pipe and screw by-pass pipe to humidifier cabinet.

Center punch the four side mounting holes on the template and drill with an 1/8" drill bit. Insert four sheet metal screws in the side mounting holes until the heads project about 3/8". Hang humidifier from the four screws and install drain pan, evaporator pad and distributor trough. Adjust humidifier until level and tighten four screws. Remark four remaining holes if necessary. Remove humidifier and drill four remaining holes.

COPPER

TUBING

PLASTIC

TUBING

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		5
Copper Pipe
1.	Retract piercing pin into valve body by turning handle
2.	counterclockwise.
	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,
5.	nuts and lower bracket.
	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
3.	valve.
	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
6.	enclosed screws, nuts and lower bracket.
	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
2.	valve.
	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.

Attach solenoid valve to side of humidifier cabinet with flow arrow pointing up, using thumb nuts provided. Do not reverse brass fittings as valve will not function if flow is reversed. Assemble distributor tube so that it is directed into the center opening of the distributor trough cover. Connect 1/4" water supply tube to brass filter at inlet of solenoid. DO NOT USE PLASTIC TUBING IN CONTACT WITH ANY HOT PLENUM SURFACE OR DUCT. IF USING PLASTIC TUBING, USE TUBE SUPPORT PROVIDED.

WIRING

Please refer to the installation instructions included with the Humidistat.

7

Connect drain hose to 5/8" spout on humidifier cabinet using hose clamp provided. Run 5/8" hose to suitable drain such as floor drain, sewer or laundry sink. Be sure hose has continuous slope and is not kinked at any point.

8

Turn on water supply and check operation of humidifier. Set humidistat to a demand setting. With the furnace off, the solenoid valve should be closed. Start the furnace, the solenoid valve should open when the blower or burner circuit is energized. Check flow of water through distributor trough and evaporator pad. The standard 990-16-76 orifice will supply approximately 3.5 GPH of water at a line water pressure of 60 psi. For low water pressures (20-40 psi) a larger orifice 990-16-75 is available to provide the same flow. Leave humidistat set at the recommended setting.
