• Foil tape roll
• Code-compliant 1/4 in. (6.35 mm) water shutoff valve and fittings

Determining Best Location for Humidifier

• Select a location for the humidifier on the supply (warm air stream) duct. for examples. Return duct mounting is acceptable if there are space restrictions on the supply duct. If you are mounting the humidifier on the return duct, simply swap “return duct” for “supply duct” throughout these instructions.
• Select a location that cannot damage the air conditioner A-coil during installation.
• Do not locate the humidifier on the furnace body.
• Mount the humidifier in a conditioned space to prevent freezing.
• Mount the humidifier at least 3 in. (78 mm) above the furnace body to allow adequate space for the solenoid valve and drain line.

Selecting Location for Humidistat

• Select a location for the humidistat on the return plenum or on the wall in the living space.
• Mounting on the return plenum is the easiest installation for the control wiring circuit.

IMPORTANT
The humidistat must be mounted upstream from the humidifier or bypass duct to ensure it is properly sensing the relative humidity of the living space. Locate the control at least 8 in. (203 mm) upstream from the humidifier in the return air duct.

Locating Closest 120 V Electrical Outlet

• Select location with access to an outlet. If not available, contact an electrician to have one installed.
• Make sure that the 18-gauge wire is adequate to reach from the humidifier to the humidistat, and also from the humidifier to the transformer. Please note that the 18-gauge wire will need to be cut into the 2 correct lengths.

How Your Humidifier Works

HE240 and HE280 humidifiers use the principle that vapor (evaporated water) is created when warm air blows over a water-soaked area. As the vapor circulates, the relative humidity rises.
Your humidity control monitors the relative humidity and activates the humidifier accordingly. The humidifier has a water supply that dispenses water evenly over a humidifier pad. The warm dry air from the furnace passes over the humidifier pad and picks up the moist air to circulate it throughout your home.
Humidified air feels warmer and more comfortable so you may be able to lower your thermostat heating setpoint, which saves money on your heating fuel bills. The end result is that your humidifier gives you a comfortable environment that is also energy efficient.
Model Specific Features
The HE280 humidifier has water savings technology built in that could save up to 30% versus leading brands. This translates to up to 20 gallons of water saved per day!

INSTALLATION

1. Turn off power to the air handling system at the circuit breaker.

2. Draw a level line on the plenum in the selected location.
   IMPORTANT
   To ensure optimal product performance, be sure the mounting template is level before marking. Use of a small level is recommended.

3. Locate the template (form number 69-2710 included in the box). For the HE240 model, cut out the tem-plate along the dotted line.

4. Tape the template in position and trace around the template.

5. Remove the template and carefully cut the rectangular opening using tin snips.

6. Disassemble the humidifier; remove the cover and take out the humidifier pad assembly.
   

7. Make sure the humidifier housing is level, then position it in the opening so the plastic tabs are in place on the lower sheet metal edge of the opening. Use pliers, as necessary, to flatten cut edges.

8. Secure the humidifier housing to the opening at the top and bottom using sheet metal screws.

9. Use the 6 in. (155 mm) starter collar as a template to mark the opening for the bypass. The starter collar end can be identified by the pliable metal tabs.

10. Carefully cut the opening for the 6 in. (155 mm) starter collar end of the flex duct. Use a drill to start the cut in the middle of the circle. Cut in an outward spiral to assist in controlling the cut.

11. Reassemble humidifier side plates to customize the orientation for your specific install. The side plate with the humidifier port needs to be on the side of the humidifier that is closest to the 6 in. (155mm) hole cut in Step 10.

12. Insert flex duct with starter collar into the 6″ (155mm) hole that was cut in Step 10. Reach into hole THROUGH THE FLEX DUCT so that the pliable metal tabs can be bent outwards into the hole. These tabs, when bent outwards, will help secure the flex duct into your home’s duct work.

13. Slide remaining loose end of flex duct over the humidifier port on the HE240/HE280, making sure that the flex duct advances past the raised plastic tabs on the port. These tabs will help to hold the flex duct in place. Verify that the damper blade has adequate clearance to move back and forth between the summer and winter positions. Secure the flex duct in place with a connector strap.

14. Seal the duct connections with foil tape. Seal both

    • the connection between the starter collar end of the flex duct and the home’s duct work and
    • the end of the flex duct to the humidifier over the top of the connector strap.

15. Reinstall the humidifier pad assembly in the humidifier housing.

16. Hinge the cover in place and secure with the thumbscrew located at the bottom of the cover.

Connecting the Plumbing

Use hot or cold water and either hard or softened water in the humidifier.
NOTE: Using hot water will increase operating costs, but may provide a small increase in the amount of humidity delivered.
IMPORTANT
Please consult local plumbing code for proper plumbing regulations before beginning. Use of a manual shutoff valve may be required to meet code in your area.

1. Shut off the water.

2. Install the water shut off valve in the water supply line at the location selected per local code.

3. Use 1/4 in. (6 mm) OD copper pipe or tubing and connect the shut off valve to the inlet side of the solenoid valve on the humidifier.

   • Insert the tubing into the solenoid valve fitting and support the valve while tightening the compression nut.

   • Place the brass compression nut over the tubing.

   • Slide the plastic compression ring over the tubing. (Discard copper compression ring provided with valve.)

   •  Install brass insert into end of tubing.
     NOTE: To prevent leaking, use plastic (Delrin) compression rings with plastic tubing. Use copper sleeve rings only with copper tubing..

   • Insert plastic supply tubing into quick connect fitting. Insert fully, and apply modest pull pressure to ensure a tight fit.

4. Use the following steps to install a 1/2 in. (13 mm) drain tube between the humidifier and the floor drain.

   • Slide the drain clamp over the tubing.
   • Push the tubing over the drain nipple on the humidifier.
   • Hand-tighten the clamp around the tubing to secure it to the humidifier drain. The clamp is tightened by compressing the two sides together so that one side fits into the ridged grove on the other side.
   • Secure the tubing (can use foil tape) along the route to prevent movement and ensure downward slope for correct drainage.
     NOTE: Cut tubing to correct length so the tubing terminates at the drain.

Connecting the Pressure Switch

1. If the humidifier is installed on the supply duct (as is recommended), the pressure switch needs to have the tubing fed to the return duct. If the humidifier is installed on the return duct, the pressure switch needs to have the tubing fed to the supply duct.
2. Drill a 3/4-in. (19 mm) diameter hole in the duct within 10 ft. (3 m) of the switch to ensure the provided tubing reaches the pressure tap elbow.
3. Insert the black rubber grommet into the duct hole.
4. Connect the tubing to the tubing fitting elbow and insert the tubing fitting elbow into the black rubber grommet.
5. Connect the other end of the tubing to the applicable pressure connection on the switch.
   • If the humidifier is installed on the supply duct (as is recommended), the tube that inserts into the humidifier needs to be attached to the black port, and the tube that runs to the return duct needs to be attached to the gray port.
   • If the humidifier is installed on the return duct, the tube that inserts into the humidifier needs to be attached to the gray port, and the tube that runs to the supply duct needs to be attached to the black port.
6. You may cut the tubing to fit the connection length between the elbow fitting and switch. It is also recommended to secure the hose to existing structures to avoid accidental disconnection.

Installing the Humidistat

1. Separate wallplate from humidistat.
   CAUTION
   Electrical Hazard
   Can cause electrical shock or equipment damage. Disconnect power before beginning installation.

2. Mark the duct-tube hole. Hold the wallplate up to the desired location on the duct and make a mark inside the duct tube hole.

3. Drill the duct-tube hole. Find your mark and drill a 1/2 in. hole in the duct. This is where the duct tube will be inserted to capture air.

4. Insert the duct tube. Insert the duct tube through the wallplate before securing to the duct.

5. Secure the wallplate. Secure the wallplate to the duct with sheet metal screws (provided).

6. Run wires through the back plate. Run wires through the top or bottom channel on the back plate when ductmounted. If installing like a thermostat on a wall, run the wires through the back.

WIRING

CAUTION
Hazardous Voltage.
Can cause personal injury or equipment damage.
Disconnect power supply before installing or servicing equipment.
IMPORTANT
All wiring must comply with applicable local code, ordinances and regulations.
Wire the humidifier solenoid valve, humidistat and transformer.

Wiring the controls and the HE280

1. Determine the length of wire necessary to run from the humidifier to the humidistat. Cut to length and strip the ends appropriately.
2. Connect the red and white wires to the C and lower U terminals on the humidistat per the wiring diagram.
3. Taking the opposite end of the wire, connect RED WIRE to one terminal on the humidifier. Connect the WHITE WIRE to the other terminal at the humidifier.
4. Using remaining wire, determine length needed to run from H6062 Humidistat to the transformer. Cut to length and strip the ends appropriately.
5. With transformer unplugged, connect the red and white wires to the transformer by loosening the screws on the transformer, wrap wire around screw post and then re-tighten the screws.
6. Taking the opposite end of the wire, connect the RED WIRE to the R terminal at H6062 and the WHITE WIRE to C at H6062.
7. Cut a short wire. Connect one end of that wire to R and the other end to the upper U at H6062.

TESTING HUMIDIFIER OPERATION

Checklist

• Humidifier is level.
• Control wiring was reviewed using circuit diagram.
• Transformer is plugged in.
• Feed line has no kinks.
• Drain line slopes continuously down and ends at floor drain.
• Water hose inside humidifier is connected to PerfectFLO™ water distribution tray.
• Tubing from pressure switch is not kinked or pinched.

After installation use the following steps to check the humidifier operation:

1. Turn on the power and the water supply

2. Ensure the shut off valve is fully opened. If saddle valve from HUMKIT is used, turn the handle to the left (counter clockwise) until there is resistance.

3. Turn the H6062 all the way up and turn on the heat by setting the thermostat to 10 ºF (6 ºC) above room temperature.
   IMPORTANT
   The furnace blower must be on to activate the humidifier.

4. Make sure that water is flowing out of the drain hose. If water does not flow, see Troubleshooting Your Humidifier section.

5. Check for leaks.

6. Reset the thermostat and H6062 Humidistat to a comfortable setting for automatic operation. (35%relative humidity is recommended.)

OPERATION

Controlling Your Humidity Settings
Your H6062 Humidistat controls your humidifier.

• Choose the humidity control setting using the combination of relative humidity/outdoor temperature setting scale on your humidity control dial.

• When the outdoor sensor is used, the H6062 will optimize the humidity level while reducing moisture condensation on the windows.
  NOTE: If the outdoor sensor is not used with H6062, as the outside temperature drops, a lower humidity setting is recommended to accommodate dewpoint effects. These settings should reduce the accumula-tion of moisture and ice on windows and other areas of the home.

• Adjust the humidity control setting to adjust for indoor activities such as cooking, showering and clothes drying, which can cause excessive levels of humidity that can accumulate moisture on your windows.
  NOTE: If these activities persist for more than a few hours, set the humidity control to the lowest setting to turn off the humidifier. If the condition does not improve, ventilate your home to remove the moisture.

MAINTAINING YOUR HUMIDIFIER

A regular maintenance program prolongs the life of your humidifier and makes your home more comfortable. The frequency of cleaning depends on the condition of your water.
You can use either hard or soft water in your humidifier, but hard water mineral deposits are more difficult to clean than soft water deposits.
Use the following procedure to clean your humidifier.
IMPORTANT
Never oil any part of the humidifier.
Once per year, depending on water quality
(either at the beginning or the end of the humidification season)

1. Disconnect the power by unplugging the transformer from the outlet and turn off the humidifier’s water supply at the shut off valve.
2. Remove the humidifier cover.
3. Remove the humidifier pad assembly from the humidifier by grasping the top of the tray and pulling it toward you.
4. Pull one side of the humidifier pad assembly frame toward you and remove the tray from the frame.
5. Gently pinch the water nozzle prongs (a pair of prongs is located on each side of the PerfectFLO™ water distribution tray) inward until you can lift the water nozzle off the tray.
6. Slide the humidifier pad out of the frame and discard the pad. It is recommended to replace the humidifier pad on an annual basis. However, if your home has hard water, the pad may need to be replaced more frequently.
7. Carefully remove any mineral deposits from the tray and frame. Be sure the frame drain hole has nothing blocking it.
8. Disconnect the drain hose from the drain fitting on the bottom of the humidifier housing.
9. Clean the drain fitting, if necessary.
10. Bend the drain hose to loosen any mineral deposits.
11. Flush the drain hose with pressurized water (a running tap) to clean the hose.
12. Reattach the drain hose to the drain fitting.
13. Slide a new humidifier pad back into the frame.
14. Snap the water nozzle back on the tray.
15. Reattach the tray to the frame.
16. Place the humidifier pad assembly in the humidifier housing and press until the assembly is completely seated. Be careful not to pinch or kink the water feed tube.
17. Replace the humidifier cover.
18. Verify the humidifier operation by following the steps in the Checking Your Humidifier for Correct Operation section.

End of Humidification Season

• Clean the humidifier and shut it off at the end of the heating season.
• Turn the water off at the shut off valve.
• Turn the H6062 to off.
• Turn the damper blade to the “summer” position.

IMPORTANT
Be sure the humidifier power is off.

Replacement Humidifier Pads

It is recommended to replace the humidifier pad on an annual basis. However, if your home has hard water, the pad may need to be replaced more frequently because of the buildup of minerals diminishing its ability to operate normally. If there is access to a water softener, it is recommended to use softened water.
