Figure 4 To add medication to the vapor: 1. Switch humidifier off and allow outlet grill to cool down. 2. Lift the outlet grill using the finger grips on each side and remove. 3. Remove the medication cup from the misting chamber. 4. Carefully add liquid medication; do not fill cup more than half full. 5. Carefully place the medication cup into the top of the misting chamber. 6. Replace the outlet grill onto the misting chamber. 7. Switch unit on. 8. After use, remove the cup from the unit and clean any residue from the cup with warm water. WARNING: DO NOT use any liquid medication other than those specifically recommended for use with a steam vaporizer. DO NOT pour medication directly into the outlet grill openings nor add it to the water in the tank or tray. CLEANING THE AIR FILTER The air intake filter will from time to time require cleaning. When the filter becomes clogged with particulate pollutants, the amount of air that passes through it is reduced. In order to avoid this condition, it is recommended to clean the filter on a regular basis. The frequency of cleaning of the filter will be determined by the amount of particulates in the environment Figure 5 where the unit is used. Should your filter need to be replaced, or become damaged or lost, replacements may be ordered directly from BIONAIRE® by visiting our website at or calling 1-800-788-5350. The filter is located behind the inlet grill cover on the side of the unit. To remove the filter for cleaning, proceed as follows (see Figure 5): 1. Open the filter cover by pulling on the two finger grips on each side of the grill, then remove to expose the filter pad. 2. Remove the dirty filter and wash in warm soapy water. Rinse well and allow to dry. 3. Clean the filter cover with a damp cloth. 4. Insert the clean, dry filter in the recess of the inner grill. 5. Carefully replace the inlet grill cover so as not to dislodge the filter from its position by first inserting the two tabs at the bottom of the grill and then closing the top edge. CLEANING AND MAINTENANCE Before cleaning, please note the following: • DO NOT use soap, detergents, abrasives, gasoline, glass or furniture polish, or boiling water to clean any part of your humidifier. These will interfere with the proper operation of your humidifier. • DO NOT use sharp or metal objects to clean mineral deposits in the tray or element. Contact with sharp objects can result in damage to the plastic. • We recommend that the tray be rinsed daily and that the unit be allowed to run out of water every second day. • Mineral deposits should be soaked in BIONAIRE®’s Clean-Away® solution or plain vinegar. DO NOT operate unit while it is soaking! • DO NOT clean any part of your humidifier in the dish washer. • NEVER mix bleach and Clean-Away® solution. Cleaning instructions: 1. Turn the unit off and unplug it. 2. Remove the water tank; then, unlock the misting chamber by rotating the latch (Figure 6) and lift it from the unit’s base. Now lift the tray from the base (Figure 7). Figure 6 Figure 7 Misting Chamber Tray Latch 3. Empty water and minerals from the tray and fill with Clean-Away® solution. Replace the tray and misting chamber in the base. (This will submerse the element in the cleaning solution). Soak for a minimum of 20 minutes to a maximum of 30 minutes. 4. Rinse the tray and heating element with clean warm water. All traces of Clean-Away® on both the element and the tray must be thoroughly rinsed off before disinfecting. Inspect the heating element (see Figure 8) for scale buildup. If present, please see “Special Maintenance - Heating Element” for further cleaning instructions. NOTE: DO NOT ALLOW WATER TO ENTER THE AIR OUTLET GRILL OR ANY OTHER OPENINGS. 5. Disinfect the water tank and tray using a solution of one teaspoon of chlorine bleach in 1 gallon of water. Let solution soak for 20 minutes, swishing every few minutes to wet all surfaces. Empty the tank and tray; rinse thoroughly until bleach smell is gone. Replace the tray in the base (Figure 7), then replace the misting chamber in the unit, making sure that the latch has been locked in position. Fill the tank with fresh water and replace it into the unit. 6. Resume normal use. SPECIAL MAINTENANCE - HEATING ELEMENT Figure 8 Should the output drop or the “EMPTY/CLEAN” light illuminate with water remaining in the tank, it will be necessary to remove scale buildup Heating Element on the heating element. Remove the misting chamber by rotating the latch and lift it from the unit’s base. Place the misting chamber on its side. The heating element will now be visible (Figure 8). Using a non-metallic brush, scrape away the scale buildup on the element. Follow steps 3-6 to complete cleaning. Note: The above special maintenance is required due to water hardness. The harder your water, the more often this special maintenance will be needed. AFTER SEASON CARE If you do not plan to use your humidifier for an extended period of time (i.e. d...
