GENERAL

1. This humidifier puts moisture into the home by spraying a fine mist of water into the warm air plenum which is carried into the living area by the duct system.
2. When wired as recommended the humidifier will operate only when the unit blower is in operation and the humidity control is calling for humidity.
3. CAUTION should be used on all applications to ensure that the water is not allowed to impinge or accumulate on the ductwork or any parts of the heating system, such as heating coils, limit controls, A-coils, etc.
4. The installation, wiring, and plumbing of this unit must comply with local codes, ordinances, and regulations.
5. Nozzle capacity (flow) is rated at 40 P.S.I. This capacity varies according to line pressure as shown in the chart. Select the nozzle that delivers the required flow at the pressure that exists in your area For example, a home requiring .50 gallons of water per hour to properly humidify and has a water pressure of 80 P.S.I. would require a .37 nozzle to do the job.
6. If the water pressure is excessive, a pressure regulator valve will be necessary to obtain the proper volume of moisture.

INSTALLING HUMIDIFIER

• CAUTION: When selecting a location for the humidifier make certain the spray will not impinge on any fan or limit controls, or any heating parts or A-Coils.
• The location selected must be a spot where the air will push the new moisture away from the humidifier.
• The humidifier must be mounted on the hot air plenum with the nozzle pointing up in the direction of airflow. On narrow plenums, mount a humidifier on the narrow side.
• If there is not sufficient room then it can be mounted further downstream, away from the heating/cooling coil.
• If it is necessary to mount the spray nozzle further away from the humidifier, remove the nozzle adapter and 45° fitting from the solenoid valve. Use fittings supplied in the parts bag to relocate the nozzle with ¼” copper tubing (not supplied).
• CAUTION: Do not allow copper tubing to come into contact with any sharp edges or sur­faces that may cause wear on the tubing.
• Tape the template on the warm air plenum in the location selected for mounting the humidifier. The template should be mounted level so the humidifier will be level when installed.
• DANGER: Make sure you are not cutting or drilling into any air conditioning or elec-trical accessories during installation. Center punch and drill four 7/64″ mounting holes.
• Drill a 3/8″ hole within the center portion of the template and cut a rectangular opening, as instructed on the mounting template.
• Install drain cup over nozzle and attach with #6 x 3/8 sheet metal screw.
• It may be desirable to install a 3/,6-inch I.D. tubing on the copper humidifier drain and run to a waste drain. When water flows through the copper drain continuously, the nozzle or the solenoid valve needs attention. An occasional drip from the drain tube when the humidifier is operating is normal.
• Attach the humidifier with four #8 sheet metal screws.

PLUMBING

Select the nearest cold water pipe and install the saddle connector and needle valve supplied with this unit. Mount the valve so water will come from the top or side. This will reduce the chance of minerals, etc., from clogging the valve. It is a self-piercing unit when installed on copper pipe. Follow the instructions supplied with the valve.

Use Copper Tubing Only

• Compression Plumbing Tips
  • a) Lighlty clean the tubing ends with fine sandpaper before making connections.
  • b) Make sure the tubing is fully inserted into the fitting before tightening the compression nut.
• IMPORTANT! Thoroughly flush the supply tubing after attaching it to the saddle valve to clear the line of debris that could block the water flow at the solenoid valve.
• The online Filter in this humidifier is assembled as shown below. Pay close attention to the proper orientation of parts for assembly and disassembly, this will assist you when cleaning.
• Slide hex nut over tubing end. (If using plastic tubing insert brass insert.) Slide the sleeve over the tubing. Push the end of the tubing into the threaded fitting slide the hex nut up to the fittings and tighten. Moderate tightness is sufficient.
• Slide tubing through a split in the bushing and insert the bushing through the humidifier wall until it snaps into place.
• Open the needle valve at the cold water pipe. Check all fittings for leaks.

MOUNTING HUMIDITY CONTROL

1. This humidifier is supplied with a patented Universal Humidistat which can be wall-mounted or duct-mounted. The wall-mounted humidistat will allow fingertip control in the living area.

2. Pull off the control knob, and nameplate and remove the cover. If a wall mount is desired, read on or if a duct mount is desired, skip to step 6.23.

3. Drill a ¼” hole in the base plate through the depression provided.

4. Select a location for the wall humidistat. The humidistat must be located on an inside wall, away from register discharges. Also, avoid sources of heat, cold, or extreme humidity vari­ation; i.e. bathrooms, kitchens, and basements.

5. The humidistat should be mounted at approximately the same height as the thermostat and you may wish to install the humidistat right next to the thermostat.

6. Cut two lengths of low voltage wire, not supplied, that will easily reach from the humidistat to the humidifier and easily reach from the 24-volt transformer to the humidifier.

7. Strip the plastic insulation ¼” to expose the copper conductor on both wires. (Four (4) wires, eight (8) ends.)

8. Route the wire you cut to reach the humidistat, through an access hole you make in the wall, to the humidifier. Seal the hole in the wall to eliminate false readings caused by drafts.

9. Route the wires through the drilled ¼” hole and attach one wire to each terminal. See the wiring diagram.

10. Mount the humidistat base plate to the wall with the long dimension horizontal and the control knob on the right side. Two 1″ self-tapping screws are provided.

11. Attach the control cover with two (6-32 x 5/16) screws. Tighten evenly for best results.

12. Remove the paper backing on the nameplate and press on the cover. Press the control knob on the shaft.

13. If you have just completed a wall humidistat, skip to step 6.35. If you desire a duct humidistat, go to step 6.23.

14. The duct humidistat must be located on the return (cold) air plenum or ductwork. CAU­TION: DO NOT install a humidistat on the supply (hot) air plenum. Permanent damage will occur to the humidistat and improper control will result.

15. Remove the two screws that attach the base plate to the humidistat. Reattach the base plate over the control shaft, using the screws just removed. Press the control knob on the shaft.

16. The humidistat mounts in a vertical (long dimension up and down) position. Remove the template backing and attach the template to the return (cold) air plenum in the proper location, keep­ing the template level.

17. Center punch and drill the two mounting holes with a 7/64″ drill.

18. Drill a 3/8” hole within the center portion of the template.

19. Starting at the 3/8″ hole, cut out the center opening with tin snips or aviation snips.

20. Remove the template.

21. Cut two lengths of low voltage wire (not supplied) that will easily reach from the humidistat to the humidifier and easily reach from the 24-volt transformer to the humidifier.

22. Strip the plastic insulation ¼” to expose the copper conductor on both wires. (Four (4) wires, eight (8) ends).

23. Place one end of the correct wire through the 3/8″ diameter hole in the humidistat mount­ing plate. Fasten one wire to each terminal. See the wiring diagram.
    When Wiring Unit To Systems That Have Multi-speed Blower Motors Or Systems Using Other Than 120 VAC Motors, Use Skuttle No. SK-431 Isolation Relay.

24. Mount humidistat to the return (cold) air plenum with two self-tapping sheet metal screws.

25. Route the wiring coming from the humidistat to the humidifier.

26. Do not allow the wiring to contact any heated surface or sharp edges. Connect one of the wires from the humidistat to the light and one to the solenoid wire.

27. With the other wire cut to reach from the transformer to the humidifier, on one end con­nect one wire to the solenoid and light wires. Connect the other wire on the same end to the wire coming from the humidistat with a wire nut. See the wiring diagram.

28. Connect the remaining end of the low-voltage wire to the two screw terminals on the 24-volt transformer. See the wiring diagram.

HUMIDIFIER CHECKOUT

• Check the humidifier operation by following the procedure outlined.
  • A. Turn the water valve to the humidifier on.
  • B. Turn humidistat to “on” position.
  • C. Set the furnace thermostat high enough to allow the furnace to come on.
  • D. When the furnace blower comes on the humidifier should start spraying provided there is adequate heat to the humidifier thermostat.
  • E. Check humidistat operation by turning the humidistat off and on and checking to see that the humidifier stops spraying correctly.
  • F. If the humidifier does not stop spraying there may be an error in wiring (consult wiring diagram).
  • G. Set the furnace thermostat low enough to allow the furnace to shut off.
  • H. The humidifier should stop spraying immediately or before the blower shuts off.
  • I. If the humidifier does not stop spraying there may be an error in wiring (consult wiring diagram).
  • J. If the humidifier shuts off correctly return to procedures C and D. Check to see that no water is allowed to impinge on ductwork or any parts of the heatinq system.
  • K. If water impingement or fallout could occur there must be a user, installer supplied suitable drain pan, plumbed with an adequate waste drain.
  • L. To assure proper operation procedures C through J should be followed 5 times minimum. To assure that no water is allowed to impinge on ductwork or parts of the heating system.
  • M. Now set the thermostat at the desired setting.
  • N. Set humidistat at the setting recommended in the chart below.

WARNING:
DO NOT set the Humidity Control TOO HIGH. Use the recommended settings shown below.

HOMEOWNER HUMIDIFIER TIPS

• If the mineral content of the water in the home is above normal, lime dust may occur in the duct distribution system and living area. Even though these lime deposits may adhere to the sides of the ductwork, this should not affect the air distribution significantly.
• In a home that has had little or no humidification, a new humidifier will tend to operate almost continuously to attain the desired relative humidity setting. This is understandable since furniture, woodwork, carpeting, plaster, and house plants will absorb the newly produced moisture to reach normal levels. This period of adjustments will usually take approximately 3 weeks.
• Fireplace dampers should be closed when not in use to eliminate natural drafts which allow humidified air to escape from the home.
• After each heating season turn water and electrical power to the unit “OFF.”
• It is suggested the spray nozzle be replaced at the start of each heating season to ensure continuous trouble-free operation of your humidifier.
• The in-line water filter should be cleaned each heating season. Loosen the hex nut, slide tub­ing out of the tube connector, and remove the filter. The solenoid valve may be disassembled for cleaning.
• For parts and services, contact your local authorized Dealer.
• If excessive moisture appears on windows or walls, reduce humidity setting on humidistat enough to eliminate condensation. If the situation continues, turn off the water valve and consult your dealer.

SAFETY PRECAUTIONS

PLEASE READ BEFORE INSTALLING HUMIDIFIER

1. Do not install a humidifier where the heating temperatures will exceed 200°F. Excessive temperatures will damage your humidifier and possibly cause an overflow condition and water damage to your home.
2. Do not install a humidifier where the surrounding temperature may be 32°F or colder. Freez­ing water will damage your humidifier and burst the supply pipe, resulting in home damage.
3. Do not cut or drill into any air conditioning or electrical accessories during humidifier in­stallation. Fatal electrocution is possible if you come into contact with a live electrical wire. Blind­ness can occur if freon contacts your eyes.
4. When the humidifier is in a finished basement or any area where water damage could occur, always connect the overflow provision of the humidifier to a suitable drain.
5. For above-ceiling installation, always install a drain pan plumbed to a suitable drain.
6. Below are listed the initial recommended settings for your humidity control. Because relative humidity affects everyone differently, these settings can be raised or lowered to suit your per­sonal comfort. WARNING: Setting your humidity control higher than the listed setting could cause condensation that would damage your home. If excessive moisture appears on windows or walls, reduce humidity setting at humidistat enough to eliminate condensation. If the situation con­tinues, turn off the water valve until the condensation is gone.
7. The installation, wiring, and plumbing of the humidifier must comply with local codes, ordinances, and regulations.
8. Read all installation instructions before installing the humidifier.
9. The manufacturer assumes no responsibility under warranty if the user does not follow stated In­stallation Instructions and Safety Precautions.
