General Gen 1000 Owner's Manual

Fresh Indoor Air Quality

INSTALLER: PLEASE FILL OUT AND MAIL WARRANTY 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 150 degrees F. For maximum evaporative capacity, install this humidifier on the warm air supply plenum.

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 (G.F. Model #GA50 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

Select location on vertical surface of warm air plenum of a forced air handling system for mounting humidifier that allows for service and maintenance. Do not install humidifier where the blanked off ends of a cooling coil will restrict air flow to the humidifier. 12-1/8” tall by 14-1/8” wide as shown.

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.

Cut out a square section

Connect 1/4" water supply tube to inlet of solenoid.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.

GCV3412 CODE VALVE INSTALLATION INSTRUCTIONS

Copper Pipe

1. Turn off water supply.

2. Clean pipe, fittings and valve with sandpaper or wire brush.

3. Apply a thin layer of flux to all surfaces to be soldered.

4. Assemble valve to pipe and/or fittings.

5. Cooling the valve by wrapping a wetted rag around the valve is optional.

6. Heat the joints with a torch. Apply solder to each joint. Continue to apply heat sufficient to keep solder liquid.

7. After solder has filled entire joint area, remove heat and allow joint to cool. Do not move or disturb.

8. Slide compression nut over 1/4” copper tube followed by compression sleeve.

9. Insert tube into valve fully and tighten nut.

10. Turn on water supply and check for leaks.

COPPER

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 in addition to a plastic ferrule and brass nut.

NOTE: D O N OT USE P LASTI C T UBING ON HOT WATER OR IN CON TAC T WIT H ANY H OT PL ENU M SUR FAC E OR DU CT. INSTALLATION OF THIS SADDLE VALVE MUST MEET OR EXCEED LOCAL CODES AND ORDINANCES.

6B WITH CONSTANT POWER TO HUMIDIFIER

Use with mechanical humidistat only. Mount a junction box and 115v. grounded outlet. Connect the on-off switch in series with the hot or black wire. Install a field supplied 24 volt relay and attach to HUM and C on the furnace control board. Install humidistat and connect one side to one yellow wire on humidifier. Connect the other side of the humidistat to one end of switch side of the relay. Connect the other switch side of the the relay to the remaining yellow wire on humidifier. Red humidifier leads

are not used for this wiring method. Do not touch red wires together. Damage to the humidifier will result.

6C WITH ELECTRONIC HUMIDISTAT - PRESSURE SENSING

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 in series with hot or black wire and Air Pressure Switch in series with the humidistat circuit. The Air Pressure Switch will detect furnace operation and supply power to the humidifier accordingly.

6D WITH ELECTRONIC HUMIDISTAT - CURRENT SENSING

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.

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

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.
