Select location on vertical surface of warm air plenum for
mounting humidifier. Stick mounting template in place
making sure the template is level. Do not install humidifier
where the blanked off ends of a cooling coil will restrict air
flow to the humidifier.

Center punch the four side mounting holes on the template
and drill with an 1/8" drill bit. Cut out center section of
template. Remove the template and insert the four sheet
metal screws until the heads project about 1/8".
COPPER
TUBING
Install evaporator plates in pan. Insert the humidifier in the
plenum such that the four screws project through the keyhole
slots. Slide the humidifier down level and tighten four screws.
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
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
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
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
several seconds to flush dirt from pipe and tubing.

Turn on water supply and check operation of humidifier. Check
flow of water by removing inspection plate and observe drip
tube. Humidifier will gradually fill 3/4 inch to 1 inch deep and
shut off. To accelerate filling, move valve actuator plate
toward pan through inspection opening.
NOTE: THIS HUMIDIFIER HAS BEEN FACTORY ADJUSTED
TO OPERATE ON WATER PRESSURES FROM 20 TO 150
P.S.I. NO ADJUSTMENT SHOULD BE NECESSARY.
NOTE: 800-IJ phenolic evaporator pan with
cast in plate rack and pan baffle is

CARE AND MAINTENANCE
Your Humidifier is engineered to give helpful and trouble-free humidification. For maximum efficiency the following cleaning procedures should be carried
out at the end of each heating season:
REPLACING EVAPORATOR PLATES AND CLEANING HUMIDIFIER
1. Turn off water supply to humidifier.
2. Disconnect the 1/4” water supply line from the humidifier.
3. Loosen the four screws holding the humidifier in place.
4. Lift humidifier up and slide out.
5. Remove old evaporator plates.
6. Clean pan with scouring pad and rinse thoroughly.
7. Replace evaporator plates with Generalaire 880 evaporator plates.
8. Carefully slide humidifier into opening to prevent breaking evaporator
plates.
9. Tighten the four screws and reconnect the 1/4” water line to the
humidifier. Turn on the water supply and check all points for leakage.
The humidifier is now ready for operation.
10. During the summer, turn off water supply to humidifier.
DO NOT DISTURB VALVE ASSEMBLY UNLESS IT SHOULD FAIL TO
FUNCTION PROPERLY.
SERVICING THE VALVE
If the valve should malfunction look for dirt in the orifice and neoprene
valve seat.
A. Turn off water supply to humidifier. Disconnect the 1/4” water supply
line from the humidifier. Loosen the four screws holding the humidifier in
place. Lift humidifier up and slide out.
B. Remove the four screws from the valve body and pull from neoprene
valve diaphragm.
C. Remove screen disc from orifice fitting with wire paper clip. Clean
orifice and screen.
D. Clean all dirt and scale frame neoprene valve seat and examine seat
for wear.
E. Replace valve body with orifice fitting on top. Do not over tighten
screws.
F. Reconnect the 1/4” water line to the humidifier. Turn on water supply
and adjust valve to shut off when water level is approximately 1/4 inch
above holes in pan baffle. When the water reaches this level turn valve
adjusting screw in slowly until water stops dripping from drip tube. To test
this setting dip water from the pan. Water should start dripping from the
drip tube. The humidifier is now properly adjusted to automatically
maintain this water level in the pan.
HOW THE HUMIDIFIER WORKS
The water supply to the humidifier is automatically controlled by the water
pressure against the neoprene pan diaphragm.
When the water level is approximately 1 inch deep in the pan, the pressure
on the pan diaphragm causes the actuator plate to pivot pushing the screw
and valve seat against the orifice, shutting off the flow of water.
As the water is drawn from the pan and evaporated through the evaporator
plates, the pressure on the pan diaphragm is reduced, allowing the actuator
plate to pivot away from the valve, opening the water inlet orifice. This
allows water to flow from the orifice through the valve chamber and drip
tube to refill the pan.
