1000 SERIES
FLOW THROUGH
POWER HUMIDIFIER

1000 Series Flow Through Power Humidifier

FOR INSTALLATION ON A VERTICAL SURFACE OF THE WARM AIR PLENUM OF ANY FORCED AIR FURNACE
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. For maximum evaporative capacity, install this humidifier on the warm air supply plenum. When wiring into a multi-speed blower circuit see Step 6C & 6D.
ADDITIONAL MATERIALS THAT MAY BE NECESSARY:

1. 1/4″ diameter plastic supply tubing or 1/4″ copper supply tubing for hot water applications
2. air pressure switch (G.F. Model #12500 suggested)
3. junction box, 115 V. grounding outlet, cover and wire
4. 1/2” I.D. drain hose

5. 8 x 3/4” mounting screws

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, a plastic sleeve on the outside with a brasscompression 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 TUBE SUPPORT P189 AND PLASTIC COMPRESSION SLEEVE P190.
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.

INSTRUCTIONS FOR WIRING HUMIDIFIER

FIG. 6A WITH FURNACE CIRCUIT BOARD
On furnaces with output terminals ACC, or EAC check output voltage to determine that terminals are 115V. Connect on-off switch in series with the hot wire.
NOTE: ALL WIRING SHOULD COMPLY WITH LOCAL ELECTRICAL CODES.

Replace evaporator pad assembly and humidifier cover. Insert low voltage six connector wiring harness from cover into chassis solenoid harness.

FIG. 6B WITH SINGLE SPEED BLOWER MOTOR
On furnaces with single speed blowers, mount a junction box and 115v. grounded outlet connected in parallel with the blower circuit. Connect the on-off switch in series with the hot or black wire.
FIG. 6C WITH TWO SPEED BLOWER MOTOR
On furnaces with a two speed blower, the humidifier and a Model 12500 Air Pressure Switch may be wired from a continuous 115 volt power source. Install the on/off switch and Air Pressure Switch in series with the hot or black wire. The Air Pressure Switch will detect furnace operation and supply power to the humidifier accordingly.
FIG. 6D WITH TWO SPEED BLOWER MOTOR
On furnaces with a two speed blower, the humidifier may be wired from a continuous 115 volt power source. Install the on/off switch in series with the hot or black wire. Install the GA50 Current Sensing Relay in series with the humidistat circuit. The Current Sensing Relay will detect furnace operation and supply power to the humidifier accordingly.
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 DC 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.
Turn on water supply and plug in power cord to check operation of humidifier. Set humidistat to a demand setting. With the furnace off, the solenoid valve should be closed and the humidifier fan not running. Start the furnace, the solenoid valve should open and the humidifier fan run when the blower or burner circuit is energized. Check flow of water through distributor trough and evaporator pad. The standard GA4231 yellow 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 GA4299 is available to provide the same flow. Leave humidistat set at the recommended setting.

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.
2. Remove cover, water distributor trough, evaporator pad, pad rails and drain pan. Clean excessive mineral deposits from the distributor trough, drain pan, pad rails and humidifier cabinet. A solution of 1/2 vinegar & 1/2 water will help loosen mineral deposits. Inspect drain hose, clean or replace as necessary.
3. If the evaporator pad has excessive mineral deposits, replace with a new “GA19” evaporator pad. Install trough, pad rails and drain pan. Replace cover, reconnect electrical plug..
4.  In heavy mineral areas or if the solenoid valve fails to function disconnect the 1/4” water supply line from the solenoid valve. Carefully pull the strainer screen (P.N. 900-8) from the valve body (P.N. 900-6). Clean the mineral deposits from all parts. If the orifice is clogged, it may be opened by inserting a small pin. Reinsert the filter into the valve body.
5. Reconnect the 1/4” water line to the solenoid valve if necessary. Turn on the water supply and check all points for leakage. The operation of the unit may be checked by starting the furnace. The humidifier operates only when the furnace blower is running or the burner circuit is energized. The humidifier is now ready for operation.
6. During the summer, turn off water supply and electrical power to humidifier.

HOW THE HUMIDIFIER WORKS

The operating principle of the humidifier is based on the most efficient and economical means of evaporating water to the air. The heat necessary for evaporating water is produced by the furnace.
The water supply to the humidifier is controlled by the electric solenoid valve. The solenoid valve and humidifier fan are controlled by a humidistat connected through an isolation relay. The humidistat is designed for wall mounting in the living area or surface mounting on the return air duct. ELECTRICAL RATING: 24 VAC/ 60 Hz.
DO NOT SET RELATIVE HUMIDITY TOO HIGH DURING COLD WEATHER. EXCESSIVE HUMIDITY MAY CAUSE CONDENSATION ON WINDOWS OR IN WALLS. REFER TO RECOMMENDED SETTINGS AS DESCRIBED IN THE HUMIDISTAT OWNERS MANUAL.
Water flows through a strainer, is metered through an orifice to provide the proper amount of water, and is supplied to the evaporator pad by the distributor trough. Air from the warm air plenum is pulled through the wetted evaporator pad by the humidifier fan and returned to the warm air plenum to be circulated through the living area. Moisture is evaporated to the air passing through the evaporator pad. Minerals are not blown into the air stream as occurs in atomizing humidifiers; they are left on the evaporator pad where a high percentage is carried off with the waste water. When the humidifier is installed and operating, no adjustments are necessary other than setting the control knob on the humidistat to the desired level of humidification. To turn the humidifier off, close water supply valve, switch electrical power off and turn humidistat off.
