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. For maximum evaporative capacity, install this humidifier on the warm air supply plenum.

When wiring into a multi-speed blower circuit see Figure 5B or 5D.

FOR INSTALLATION ON A VERTICAL

SURFACE OF THE WARM AIR PLENUM

OF ANY FORCED AIR FURNACE

INSTALLER: PLEASE LEAVE INSTALLATION INSTRUCTIONS WITH HOME OWNER

ADDITIONAL MATERIALS THAT MAY BE NECESSARY:

1. 1/4" diameter plastic supply tubing or 1/4" copper supply tubing for hot water applications

2. Current sensing relay (Braeburn Model 229051 suggested)

3. Junction box, 115 V. grounding outlet, cover and wire

4. 1/2” I.D. drain hose

5. #8 self piercing sheet metal screws

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.

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

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.

FLOW THROUGH POWER HUMIDIFIER

18 GPD / 120V

Select location on vertical surface of warm air plenum for mounting

humidifier. Tape 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.

Cut out center section of template.

Open cover and remove evaporator pad assembly. Humidifier chassis is

self retaining, slide top side in first then slide chassis down. Level chassis

and install eight screws.

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 and 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.

Connect 1/4" water supply tube to inlet of solenoid. DO NOT USE

PLASTIC TUBING IN CONTACT WITH ANY HOT PLENUM

SURFACE OR DUCT. IF USING PLASTIC TUBING, USE INSERT

FOR PLASTIC TUBING AND PLASTIC COMPRESSION SLEEVE

(INCLUDED WITH SADDLE VALVE KIT).

Connect drain hose to 1/2" spout on humidifier cabinet using hose clamp if

necessary. Run 1/2" 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 6 CIRCUIT DESCRIPTION The humidifier is connected to the 120 volt AC circuit through a control relay. The secondary coil of an isolation transformer, a diode and resistor supply 24 volts for the control circuit which also includes the humidistat and relay coil. When the control circuit is completed by the humidistat, the relay closes, supplying 120 volts to the fan motor and 24 volts to the solenoid valve. 7 Turn on water supply and plug in power cord to check operation of humidifier.

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: 1. Turn off water supply and electrical power to humidifier. RECOMMENDED AT 2. Remove cover, water distributor trough, evaporator pad, pad rails and drain pan. Clean excessive mineral SETTING OUTSIDE deposits from the distributor trough, drain pan, pad rails and humidifier cabinet.
