General 1000, 1000xm Owner's Manual

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.

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 screen, � 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.

POWER HUMIDIFIER

COPPER TUBING

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.

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.

Fresh Indoor Air Quality

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.

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.

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

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.

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.

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.
