INSTALLATION INSTRUCTIONS
IMPORTANT:
- THIS HUMIDIFIER MUST BE INSTALLED BY A QUALIFIED CONTRACTOR.
- DO NOT INSTALL ON ANY SYSTEM WITH WATER PRESSURE LESS THAN 40 P.S.I.
Installation on water systems with hardness ratings greater than 7 grains is not recommended. Such installations can result in nozzle blockage, dripping, erratic spray patterns, and other maintenance problems. Hardness above 7 grains will also produce dust from solids in the water supply, which will be distributed throughout the home. Consult your municipal water provider before continuing.
SAFETY PRECAUTIONS
READ THESE PRECAUTIONS AND ALL INSTALLATION INSTRUCTIONS BEFORE INSTALLING THE
HUMIDIFIER.
NOTE: Skuttle Mfg. Co. assumes no responsibility under warranty if the installer does not follow these instructions and safety precautions.
- Do not install a humidifier where the heating temperatures can exceed 200°F. Excessive temperatures will damage the humidifier, possibly causing an overflow condition and water damage to the home.
- Do not install a humidifier where the surrounding temperature can be 32°F or colder. Frozen water will damage the humidifier and burst the supply pipe, resulting in home damage.
- Do not cut or drill into any air conditioning or electrical accessories during humidifier installation. DANGER: Electrocution is possible if you come in contact with a live wire; blindness can occur if refrigerant contacts your eyes.
- When the humidifier is installed in an area where water damage could occur, connect the humidifier’s overflow provision to a suitable drain pan.
- For above-ceiling installations, always install a drain safety pan, plumbed to a suitable drain.
- For initial recommended humidistat settings, refer to Table 1, below. (Because relative humidity affects people differently, these settings can be raised or lowered slightly to suit personal comfort levels.)
- CAUTION: Setting the humidistat higher than the recommended setting can cause condensation, resulting in home damage. If excessive moisture appears on windows or walls, reduce the humidistat’s humidity setting enough to eliminate condensation. If the situation continues, turn off the humidifier’s water source until the condensation is gone.
- Make sure the installation, wiring, and plumbing of the humidifier comply with local codes, ordinances, and regulations.
INSTRUCTIONS
GENERAL INFORMATION:
- 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.
- When wired as recommended, the humidifier will operate only when the furnace blower is operating and the humidistat is calling for humidity.
- The nozzle capacity (flow) is rated at 40 P.S.I. This capacity varies according to line pressure, as shown in Table 2, below. Select the nozzle that delivers the required spray by the pressure in your area.
Table 2 EXAMPLE: A home that requires .50 gallons of water per hour for
proper humidification, and which has a water pressure of 80 P.S.I., would need
a .37 nozzle to do the job.
If the water pressure is excessive, a pressure regulator valve will be
necessary to obtain the proper volume of moisture.
REQUIRED TOOLS
Aviation Snips • #2 Flathead Screwdriver • #1 Phillips Screwdriver • Ad- justable Wrench • Pliers • Electric Drill with 7/64″, 3/32″, 1/4″ and 3/8″ Drill Bits • Hammer • Center Punch
INSTALLING THE HUMIDIFIER
-
CAUTION: When selecting a location for the humidifier, make sure the spray will not impinge or accumulate on any fan, limit controls, resistance heating coils, or heating/air coils.
-
Select a location where the air will push the spray mist away from the humidifier.
-
Mount the humidifier on the warm air plenum only, with the nozzle pointing up in the direction of airflow (see Figure 1, left). On narrow plenums, mount the humidifier on the narrow side.
-
If there is not enough room on the warm air plenum, mount the humidifier further downstream on the warm air duct, away from the heating and cooling coil.
-
If it is necessary to mount the spray nozzle further away from the humidifier (to move the nozzle further into the air stream for better absorption), remove the nozzle adapter and 45° fitting from the solenoid valve. Use the fittings supplied in the parts bag to relocate the nozzle using 1/4″ copper tubing (not supplied). (See Figure 2, below, left.) CAUTION: Do not allow copper tubing to come in contact with sharp edges or surfaces that may cause wear on the tubing.
-
Tape the template (provided) on the warm air plenum in the location selected for the humidifier. CAUTION: Make sure the template is level.
-
Center punch and drill four 7/64″ mounting holes, as shown on the template. DANGER: Make sure you are not cutting or drilling in Figure 2 to air conditioning or electrical accessories.
-
Drill a 3/8″ hole in the center of the shaded area of the template; cut a rectangular opening (staying within the shaded area), as indicated.
-
Install the drain cup over the nozzle; attach it with a #6 x 3/8″ sheet metal screw. (See Figure 3, left.)
-
Install 3/16″ I.D. tubing on the copper humidifier drain and run it to a waste drain. (An occasional drip from the drain tube when the humidifier is operating is normal.)
-
Attach the humidifier with four #8 sheet metal screws.
INSTALLING THE INSPECTION WINDOW
NOTE: A clear, plastic window is supplied with the humidifier to be
mounted on the ductwork. This allows you to observe whether the humidifier is
functioning properly and whether there is water impinging on parts or surfaces
within the system.
- Select a mounting location on the ductwork where the humidifier spray nozzle can be viewed easily.
- Drill a 3/8″ hole and cut a 4-1/2″ x 2″ rectangular opening. DANGER: Make certain that you are not drilling or cutting into any air conditioning or elec-trical accessories during installation.
- Position the window over the opening; mark and center-punch the two mounting hole locations.
- Drill the two 3/32″ mounting holes.
- Attach the window with the two #6 Phillips-head screws provided.
PLUMBING THE HUMIDIFIER
Select the nearest cold water pipe and install the saddle connector and needle
valve, supplied with this unit. Use copper tubing only.
- The needle valve is a self-piercing valve when installed on the copper pipe. Follow the instructions supplied with the valve.
- Mount the valve so that water will come from the top or side. This will reduce the chance of minerals clogging the valve.
Follow these compression plumbing tips
- Lightly clean the tubing ends with fine sandpaper before making connec-tions.
- Make sure the tubing is fully inserted into the fitting before tightening the compression nut.
IMPORTANT: After attaching the saddle valve, thoroughly flush the supply
tubing to clear the line. Otherwise, debris could block the water flow at the
solenoid valve.
IMPORTANT: To assist you with cleaning, note the proper orientation of
parts for assembly and disassembly (Figure 4, below).
- Slide the hex nut over the copper tubing end. Slide the brass ferrule over the tubing. Push the end of the tubing into the threaded fitting and slide the hex nut up to the fitting. Tighten the nut.
- Slide the bushing over the tubing; insert the bushing through the humidifier wall until it snaps into place.
- Open the needle valve at the cold water pipe. IMPORTANT: Check all fittings for leaks.
MOUNTING THE HUMIDISTAT
- NOTE: See the installation instructions packaged with the enclosed humidistat (humidity controller).
- NOTE: When wiring the unit to a system that has a multi-speed blower motor, or that uses a motor other than 120 VAC, include the Skuttle A50 Interface Relay in your installation.

HOMEOWNER HUMIDIFIER TIPS
- If the mineral content of the water in your home is above normal, lime dust may form in the duct distribution system, as well as in your living areas. Even though these lime deposits may adhere to the sides of your ductwork, they will not significantly affect air distribution.
- In a home that has had little or no humidification, a new humidifier may op-erate almost continuously to attain the desired level of relative humidity. This is because furniture, woodwork carpeting, plaster, and houseplants will absorb the newly-produced humidity to reach normal moisture levels. This period of adjust-ment will take approximately three weeks.
- Natural drafts in the home can cause humidified air to escape through open fireplace dampers. Make sure they are closed when not in use.
- When the weather turns warmer, humidification is unnecessary. IMPOR-TANT: Turn the water and electrical power to your humidifier ‘OFF” after each heating season.
- When water frequently flows through your humidifier, the nozzle and/or solenoid valve can become clogged by lime and other mineral deposits, thereby diminishing humidification effectiveness. When this occurs, you should replace the affected part(s). NOTE: It’s a good idea to replace the spray nozzle at the start of each heating season to help ensure continuous, trouble-free operation of your humidifier. (You may wish to have your heating or plumbing contractor perform this service for you.)
- The inline water filter should be cleaned at the end or beginning of each heating season. To do so, loosen the hex nut (see Figure 4, left, top), slide the tubing out of the tube connector, and remove the filter. At this time, the solenoid valve may be disassembled for cleaning.
- IMPORTANT: For parts and service, contact your local authorized dealer.
CAUTION: If excessive moisture appears on windows or walls, reduce the humidity setting on your humidistat enough to eliminate condensation. If the situation continues, turn off the water valve that permits water flow to the humidifier, and contact your heating or plumbing contractor.
