INSTRUCTIONS WITH HOME OWNER

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 pan. The humidifier may be mounted on the warm or 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

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

COPPER TUBING

PLASTIC TUBING

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.

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.

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.

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.

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.

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.

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.

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.

WIRING

Please refer to the installation instructions included with the Humidistat.

GENERALAire

Sélectionner un emplacement sur la surface verticale d'un plénum d'air chaud ou de retour d'air pour monter l'humidificateur. Pour les plénums de 9 1/2 po à to 15 po, utiliser la plaque adaptatrice 1040AD et les 5 vis, 3 vis en haut (modèle DM). Mettre la matrice de montage en place en s'assurant qu'elle soit à niveau. Ne pas installer l'humidificateur ou le tuyau de dérivation de 15 cm (6 po) à l'endroit où l'extrémité de la plaque d'obturation d'un serpentin refroidisseur pourra restreindre le débit d'air vers l'humidificateur. Prolonger la ligne horizontale depuis le milieu du gabarit jusqu’à la chambre à air voisine. Marquer un cercle de 6 po à une distance de 10 à 15 po du côté de l'humidificateur, sur la ligne centrale du boîtier, à l'aide d'un collier de raccordement pour guider.
