FREQUENTLY ASKED QUESTIONS

Question:

Answer: The unit will work on most forced air furnaces incorporating a heating source, a supply duct, and a return duct at least 8” in width.

Comment: The technology used in this humidifier to deliver moisture to the air is the simplest and easiest style, a bypass type evaporative humidifier. Your furnace fan creates a pressure difference between the supply air (hot, high pressure) and return air (cold, low pressure). By installing a bypass tube between the supply and return duct a small amount of air is forced (via the pressure difference) to flow from the supply duct through the humidifier’s evaporator pad and back into the return duct. What will differ from furnace to furnace or home to home is how much moisture or capacity you will get from the unit. There are several factors which will affect this, how old is your home, how old is your furnace, how well insulated is your home. For example, the capacity for this unit is 15 US gallons per 24 hrs of operation. This is based on ARI standards (120’F hot air temp, 60’F water supply temp, 0.5” static pressure difference between supply & return duct), used by all humidifier manufacturers. If your furnace is a hi efficiency or pulse type furnace the hot air temperature may be less, or the length of time the furnace burner is on may be less; therefore as a rule of thumb we would say you would get approx. 75% to 80% of rated output.

Question: How much moisture does the humidifier deliver to

the air in my home?

Answer: This model will deliver 15 US Gallons (12.5 Imperial gallons, 57 litres) per 24 hours of operation.

Comment: 24 hours of operation means at design conditions; your furnace will only deliver the required hot air (120’F) when it is on. Your furnace should not cycle more than 1/3 of the time so the 24 hours of humidifier operation may take up to 3 days to complete.

Question: How much water does this humidifier use?

Answer: This humidifier is 100% efficient, meaning all the water it uses is delivered to the air to humidifier your home. It will use 15 US gallons (12.5 Imperial gallons, 57 litres) per 24 hrs of operation.

Comment: As mentioned above 24 hours of operation means at design conditions – your furnace will only deliver the required hot air (120’F) when it is on. Your furnace should not cycle more than 1/3 of the time so the 24 hours of humidifier operation may take up to 3 days to complete.

Question: I’m replacing an old humidifier on my furnace

can I use the old components?

Answer: You should replace all the components to ensure good operation. You may be able to utilize the existing duct cut outs for the new install however some reworking may be required.

Comment: As a rule we like to see you change all the components, particularly the water supply tube. As over time minerals, solids, or sludge may have built up, these will very quickly clog the water inlets, or over time the tube may have become worn or leaky. Replace the bypass duct as well, there may be secondary dampers unseen which will block air or again

What type of furnaces will this humidifier work on?

there may be unseen wear. The same goes for electrical components or wiring these may be malfunctioning or worn out. Note: If you have a humidifier which was interlocked with your furnace (meaning the humidifier only came on when the furnace came on) then the old transformer is wired in with your furnace. Do not attempt to disconnect this transformer from the furnace only disconnect the low voltage side wires for the humidifier and tape over the terminals.

Question: I’ve installed the humidifier on my furnace and it

is functioning properly but I do not feel anything and humidistat reading is not changing, is the humidifier working?

Answer: As long as there is hot air going through the humidifier and there is water pan and the drum assembly is getting wet then moisture is being delivered to the air in your home.

Comment: All year, and especially during the winter months when many combustion appliance are operating in your home, fresh outdoor air is required to ensure a healthy environment for your family. Do not think of your home as a sealed bubble, no matter how well insulated, all homes breath (some more than others). The cold dry outside air is mixing with the air in your home constantly, even when your furnace is not running. A furnace humidifier will work to offset the constant effect the dry outside air has on your home, and your home’s furnishings. Throughout the winter there is a constant diminishing and replenishing of moisture levels in the home, conditions inside and out rarely remain stagnant for any length of time.

SELECTION OF LOCATION

TO MOUNT THE HUMIDIFIER

All bypass type furnace-mount humidifiers rely on the pressure difference which exists between the supply duct (hot air) and the return duct (cold air) to create an air flow through the humidifier’s evaporator pad. The air will ALWAYS flow from hot (high pressure) to cold (low pressure).

•INSTALLATION TIP: Before starting fully plan out the installation. Check for the locations of the humidifier, bypass collar & damper, and the humidistat and associated sensors. Plan the length and type of ducting required, the water supply, the water drain, the electrical wiring, and a constant 120 volt outlet to plug in the transformer. This will ensure your installation goes as easy and quickly as possible

1. The humidifier body and bypass tube are installed at eye level, easily accessible for installation and routine maintenance.

2. The space between the humidifier body and bypass tube are

Not all installations will be as shown above – in cases where:

• The bypass duct required is more than the supplied 30”

• The bypass collar and damper must be installed above or below the humidifier

• The bypass collar and damper must be installed perpendicular to the humidifier

HUMIDIFIER BODY INSTALLATION

This humidifier is designed to be mounted on the return duct (cold air) for safety reasons. This will minimize the exposure to high temperatures and extend product/component life. Always take precaution to ensure that water supply tube, water drain tube, any electrical wiring does not become kinked or come into contact with sharp edges or hot surfaces. Keep in mind that the humidistat must be mounted at least 6” upstream from the humidifier cabinet, where moist air enters the duct.

CAUTION: When cutting or drilling into ducting take care not to damage any air-conditioning coils or other furnace apparatus.

CAUTION: Wear safety glasses and work gloves when installing this unit, sharp metal edges can cause severe injury.

CAUTION: Turn the furnace off before starting this installation.

This humidifier cabinet consists of two side panels (bypass side panel and motor side panel), a front cover, and a water pan. The surface of the duct will form the rear of the humidifier cabinet.

STEP #1: RIGHT HAND DUCTING OR LEFT HAND DUCTING

Once you have decided the best location for the humidifier determine if the unit must be left or right hand ducting. This will depend on whether the hot air duct is to the left or right of the cold air duct. (Fig. 3) The side panels are symmetrical so setting up for left or right hand ducting is done by flipping the panel 180 degrees. (Fig. 4)

STEP #5: ELECTRICAL INSTALLATION

This unit is supplied with a 24 volt plug in transformer. The transformer must be plugged into a constant (one that will not be shut off) 120 volt outlet. The transformer is supplied with 10 feet of low voltage wire which must feed the humidistat and the humidifier’s drum motor. Select an outlet within the 10 feet.

HUMIDISTAT

The humidifier is supplied with an exclusive universal humidistat which can be either wall mounted as furnished or, with a few minor changes, be mounted on the return (cold) air plenum/duct. Either wall mounting or plenum/duct mounting works equally well for humidity sensing and control. Wall mounting provides easy access to adjust the humidistat setting since it is located in the living area. Plenum/Duct mounting provides a simple installation (you should not have to purchase extra low voltage wire or fish the wires through the wall).

installations, the humidistat is installed near the heating thermostat for easy adjustment and wiring.)

3. Because the humidistat will be located further away from the humidifier you will have to purchase approximately 15 to 20 feet of 20 ga low voltage wire.

4. Drill a small hole in the wall and then fish the low voltage wire out thru the hole. Leave approximately 6 inches of low voltage wire leads outside the hole for humidistat connection.

HUMIDIFIER OPERATION

ROTATING DRUM HUMIDIFIER

Because this rotating drum humidifier utilizes a water pan/reservoir the unit is 100% efficient, all the water used is delivered to the air. For this reason the unit does not have to be interlocked with the furnace cycles, the drum can rotate whether the furnace is heating or not, no water will be wasted and the humidistat will control the amount of moisture delivered to the air.

CONTROLLING THE HUMIDITY LEVEL

The mechanical humidistat supplied with this unit is to control the amount of moisture added to the air in your home – It will sense the relative humidity level in the air and work as an ON/OFF switch to control the humidifier, regardless of whether the furnace is running.

At the beginning of the heating season it may take sometime to build up the relative humidity level in your home to the desired level – For the first few weeks turn the humidistat up high to ensure the humidifier will run. After you feel that you have achieved the desired relative humidity level turn the humidistat down until it cycles the humidifier OFF. The humidifier will then work to maintain the relative humidity at that level.

RECOMMENDED MANUAL HUMIDISTAT SETTINGS

OUT SIDE AIR TEMPERATURE MAXIMUM RELATIVE HUMIDITY SETTING

If condensation continues to form on windows at these settings reduce the humidistat setting by successive 5% increments. After each reduction in setting allow 6 hours for equilibrium to be reached before readjustment.

If condensation persists with progressively lower settings made during a 3 day period turn off the water supply at the saddle valve, turn the humidistat to OFF and consult your heating contractor.

When your house is unoccupied for longer than 3 days during the winter always set the humidistat down to 15% so that severe weather during your absence will not result in condensation which may cause damage to your home.

ACHIEVING AND MAINTAINING A HUMIDITY LEVEL

Outside conditions are the primary factor affecting the humidity level in your home. The colder it gets outside the less moisture the outside air will have, your home brings in the outside air and the humidifier will work to add moisture to it. As outside conditions change the humidity level in your home will change as well. Other factors which will affect humidity levels in the home include, how many air-changes your ventilation system delivers, the amount of people occupying the home, air leaks, the use of showers, exhaust fans, HRV’s, and the use of fireplaces or wood stoves.

SAFELY OPERATING A FURNACE HUMIDIFIER

Proper control of the relative humidity level in the home is key to ensuring good Indoor Air Quality (IAQ) for your home as well as protecting against moisture damage.

Although a relative humidity environment of 45 to 50% may be desirable, setting your humidistat at that point when outside air temperatures are below 30˚F (-1˚C) can cause condensation on windows and walls. Continued condensation for extended periods of time may result in structural damage. Use the chart below as a guide for maximum relative humidity settings at the different outdoor air temperatures.

SUMMER SHUT DOWN

During the summer season the humidity level in the air is quite high. Therefore it is advisable to shut off the humidifier system. Complete the following steps at the end of the winter season.

1. Close the water supply at the saddle valve.

2. Turn the humidistat knob to the OFF position.

3. Empty and clean the water pan.

4. Close the bypass air damper.

CARE AND MAINTENANCE

Because drum humidifiers utilize a water pan/reservoir they are susceptible to water deposits and mineral build up, for this reason we strongly recommend that the yearly maintenance include

• Replacing the evaporator pad

• Cleaning/replacing the float & valve assembly

• Cleaning/replacing the water pan

If you complete all the above tasks at once the amount of time involved will be greatly reduced and your humidifier will continue to work at peak efficiency.

4. Gently remove the drum/evaporator pad assembly at the bearing end (open end) first. Take care not to lose the bearing which the drum shaft rides in. Once the bearing side is removed you will be able to tilt the drum/evaporator pad assembly out from the motor coupling. (Fig. 40b)

5. Hold the drum assembly in a horizontal position and pull the bushing out with your fingers (Fig. 40c).

6. Slide the evaporator pad off the drum cage.

7. To replace the pad keep the bushing in the extended position and slide the evaporator pad over the spokes until it is against the disc flange.

8. Push the bushing back along the shaft to the stop lugs. The evaporator pad is now locked into position.

9. Replace the drum/evaporator pad assembly completing step 4 in reverse motor coupling end first.

10. Close the front cover.

11. Turn on the water supply and plug the transformer back in.

CLEANING OR REPLACING THE FLOAT VALVE ASSEMBLY/COMPONENTS

(Figures 41 a, b, c)

To clean or replace the float valve assembly/components follow the steps below.

1. Unplug the transformer (turn power off to the humidifier).

2. Turn off the water supply at the saddle valve.

3. Open the humidifier front Cover (Fig. 41a). The cover is snap closed on the left hand side, to release slightly deflect the front cover flange at the bottom left and lift up. In the fully open position the cover will stay open.

4. If you wish to replace the entire float valve assembly included
