ENGLISH INSTALLATION INSTRUCTIONS
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.
INSTALLATION: The humidifier may be mounted on the horizontal warm air duct only.
See Typical Installation. The following illustrations show steps for installing the
humidifier on the horizontal supply duct of a forced warm air furnace. For maximum output, install the humidifier
perpendicular to the air flow as shown. On supply ducts less than 16" wide the humidifier may be mounted parallel
to the air flow, but will have reduced evaporative output.

DRUM HUMIDIFIER
FOR INSTALLATION ON
THE HORIZONTAL SUPPLY
DUCT OF ANY FORCED
WARM AIR FURNACE
Select a location on the bottom surface of the warm air supply duct for mounting the humidifier. The mounting position
should be at least 24" from the vertical supply plenum. Apply the mounting template.
Install the right angle metal baffle on the upper inside surface of 8" or deeper supply ducts. Position the baffle 1" upstream
from the centerline of the rotating drum. Mark and drill two
1/8" holes. Mount the baffle with the two sheet metal screws provided. For maximum evaporative output the 2" leg of the
baffle should extend down.
Center punch and drill the 6 mounting holes with a 1/4" drill. Cut out center section of template. Remove remaining
template. Place mounting bracket inside duct with the 6 mounting studs down through the 1/4" holes. THE LONG
STUDS HOLD THE MOTOR END OF THE HUMIDIFIER.
Push two flat push-nuts on the central studs to hold the
mounting bracket in place.
Place humidifier on the mounting studs and fasten in place with the six thumb nuts supplied.
NOTE: If overflow protection is required, slide 5/8" I.D. vinyl
tube (Pt. No. 1099-16) over quick-drain spout and run to suitable drain connection. Use a strain relief clamp within 36"
of humidifier to prevent drain tube from pulling on quick-drain.
Drain tube is not supplied with humidifier but is available in 5, 15 and 1O0 foot lengths.
COPPER
TUBI NG
PLASTIC TUBI NG
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.
Connect the W' water supply tubing to the humidifier. 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. DO NOT USE PLASTIC TUBING IN CONTACT WITH
ANY HOT PLENUM SURFACE OR DUCT. IF USING PLASTIC TUBING, USE TUBE SUPPORT PROVIDED.

POUR INSTALLATION SUR LE
CONDUIT DE DISTRIBUTION
HORIZONTAL DE TOUTES LES
FOURNAISES A AIR CHAUD PULSE
Les illustrations suivantes indiquent les etapes de I'installation de I'humidificateur sur le conduit de distribution
horizontal d'une fournaise & air pulse. Pour un rendement maximal, installer I'humidificateur perpendiculaire au debit
d'air tel qu'indiqu& Pour les conduits de moins de 16 po de
large, I'humidificateur peut etre monte parallele au debit
d'air, mais le rendement en vapeur en sera reduit.
Choisir un emplacement sur la surface du fond du conduit d'approvisionnement d'air chaud pour installer
I'humidificateur. La position de montage devrait etre &au moins 24 po du plenum d'air chaud vertical. Appliquez
matrice de montage.
AIR CHAUD
Marquer au pointeau et percer les 6 trous de montage & I'aide
d'un foret de 1/4 po. Decouper la section centrale de la matrice.
Retirer le restant de la matrice. Poser le support de montage &
I'interieur du conduit & I'aide des 6 montants & travers les trous de 1/4 po. LES MONTANTS LONGS SOUTIENNENT
L'HUMIDIFICATEUR D,L'EXTREMITE DU MOTEUR. Appuyer deux ecrous capuchon plats sur les montants centraux afin de tenir le support de montage en place.
Installer le deflecteur en metal & angle droit sur la surface superieure interieure des conduits d'alimentation de plus de 8
po. Positionner le deflecteur & 1 po en amont de la ligne centrale du tambour rotatif. Marquer et percer deux trous de
1/8 po. Monter le deflecteur avec les 2 vis taraudeuses fournies. Pour un rendement de vapeur maximal, le pied de 2
po du deflecteur devrait etre oriente vers le bas.
Poser I'humidificateur sur les montants et fixez-le en place & I'aide des 6 ecrous & ailettes fournis.
