pointy object (ie nail) carefully remove the inlet filter.

5. The inlet filter should be fairly clean and free of debris.

6. Replace or clean the inlet filter if required. If it is punctured in anyway

replace immediately. Remember the filter protects the orifice fitting and

solenoid.

7. Position the cleaned or new filter in the solenoid valve inlet. Push the

inlet filter in place.

8. Carefully reconnect the water supply tube. Hand tighten the nut first

taking care not to strip the threads on the valve, use an adjustable

wrench to tighten down a couple more turns - DO NOT OVER

TIGHTEN, you may strip the threads on the solenoid valve. If leaks

occur you can tighten later to fix them.

9. Reconnect the bypass tube onto the humidifier side and secure in

place with the 6” spring clamp.

10. Turn on the power to the humidifier, Turn on the water supply to the

humidifier, Turn on your furnace.

11. Run the humidifier and check for and repair any leaks.

REPLACING A SOLENOID VALVE (REFER TO FIG 3 A,B,C)

At some point it may become necessary to replace the solenoid valve.

Follow the steps below to complete the repair. It is recommended that

when you replace a solenoid valve you replace the water inlet filter &

the orifice fitting at the same time.

1. Turn off the power to the humidifier, Turn off the water supply to the

humidifier, Turn off your furnace.

2. Remove the bypass tube from the side of the humidifier, 6” spring

clamp secures it in place.

3. Using a wrench remove the water supply tube from the solenoid

valve.

4. On the outlet side of the solenoid valve is the flexible water supply

tube use a wrench to remove this tube from the solenoid valve.

5. Remove the solenoid valve wires from the electrical terminals on the

side.

6. Remove the solenoid valve from the humidifier, 2 screws hold the

valve in place. Depending on the solenoid valve used there may be

a rubber washer installed on each screw. Do not lose these washers

as they are used to reduce valve vibration.

7. Install and secure the new valve in place using the 2 screws remove

earlier, be sure to use the rubber washers

8. Install a new water inlet filter in the solenoid valve’s inlet, it is push fit

in place. (refer to inlet water filter replacement regards installation)

9. The orifice fitting used to meter the water flow to the distribution tray

is located in the inlet of the flexible water supply tube remove in step

4. Remove and discard old fitting and replace with a new one. (refer

to the orifice fitting replacement regards installation)

10. Connect the solenoid valve wires to the 2 electrical terminals marked

24 Volt OUT.

11. Carefully reconnect the water supply tube and the flexible water

supply tube to the solenoid valves inlet and outlet. Hand tighten the

nuts first taking care not to strip the threads on the valve, use an

adjustable wrench to tighten down a couple more turns - DO NOT

OVER TIGHTEN, you may strip the threads on the solenoid valve. If

leaks occur you can tighten later to fix them.

12. Replace the bypass tube on the humidifier’s side and secure with

spring clamp.

13. Turn on the power to the humidifier, Turn on the water supply to the

humidifier, Turn on your furnace.

14. Run the humidifier and check for and repair any leaks.

REPLACING AN ORIFICE FITTING (REFER TO FIG 4 A,B,C)

The orifice fitting is located in the flexible water supply tube feeding

water from the solenoid valve to the distribution tray. The fitting is

installed at the solenoid valve end. This fitting is used to meter the

amount of water supplied to the humidifier. Over time and depending

on the condition of your water it may become plugged and replacement

will be necessary. We recommend that when you replace the orifice

fitting you replace the water inlet filter at the same time. Follow the

steps below to complete the repair.

1. Turn off the power to the humidifier, Turn off the water supply to the

humidifier, Turn off your furnace.

2. Remove the bypass tube from the side of the humidifier, 6” spring

clamp secures it in place.

3. Using a wrench remove the water supply tube from the solenoid

valve.

4. On the outlet side of the solenoid valve is the flexible water supply

tube use a wrench to remove this tube from the solenoid valve.

5. Install a new water inlet filter in the solenoid valve’s inlet, it is push fit

in place. (refer to inlet water filter replacement regards installation)

6. The orifice fitting is located in the inlet of the flexible water supply

tube. You should be able to remove this fitting by hand you may use

a needle nose pliers if required.

7. Install a new orifice fitting it is push fit in place.

8. Carefully reconnect the water supply tube and the flexible water

supply tube to the solenoid valves inlet and outlet. Hand tighten the

nuts first taking care not to strip the threads on the valve, use an

adjustable wrench to tighten down a couple more turns - DO NOT

OVER TIGHTEN, you may strip the threads on the solenoid valve. If
