How Your Warm Mist Humidifier Works
Your Bionaire® Warm Mist Humidifier is designed
to allow the proper amount of water to flow out
of the tank and through the water purification
filter. The filter takes most of the minerals and
sediment out of the water before the water
enters the heating chamber where the
Electronic Thermal Control heating element
warms the water. Air is drawn in through the
grill openings located in the back of the unit and
mixed with steam in the misting chamber. The
warm mist is then dispersed out of the top of the
misting chamber through the outlet grill and into
the room.
NOTE: A humidity level below 30% can be
unhealthy and uncomfortable. The recommended
humidity level is between 45%-55%.
1. Be sure the humidifier is disconnected from
the electrical outlet and the power dial is in
the 0 - off position.
2. Select a location for your humidifier, on a flat
surface, about 10cm away from the wall. Do
not place your humidifier on furniture. A floor
location that will not be damaged by
moisture is best.
3. Remove the water tank (see Figure 1).
Remove the Water Purification Filter (In some
circumstances the filter may be contained
within a bag. Please remove the bag.). Soak
thoroughly by immersing filter in water for 5
minutes. Then replace in the water tray and
wait 15 minutes for water to pass through
the filter before turning on the unit.
4. Make sure the water tray is free of foreign
objects by removing the Mist Chamber. To
remove this stack you must move the Safety
Lock (M) that secures both parts in place.
(Replace the Mist Chamber over the heating
element and make sure that the Safety Lock
dial is in the "Lock" position).
Filling the Water Tank
NOTE: This humidifier holds about 5.5 litres of
water in the tank and humidifier base. The
humidifier will produce up to 11.5 litres of
moisture over a 24-hour period.
1. Be sure the humidifier is disconnected from
the electrical outlet and the power dial is in
the 0 - off position. Remove the water tank.
2. Twist off the tank cap located on the bottom
of the reservoir by turning counter clockwise
and fill the water tank with cool, fresh water.
Do not fill with warm water as this may
cause leaking.
NOTE: If the filter or water tray are dry, wait 15
minutes before turning on the unit. The 15
minute wait is necessary to ensure that the filter
is properly saturated and the water is at its
optimal level for best performance.
3. After filling the tank, replace the tank cap by
firmly turning clockwise and then replace the
water tank on the base. The tank will
immediately begin to empty into the base.
4. Plug the power cord into a convenient and
suitable power supply.
1. Fill the water tank (see “Filling the Water
Tank” instructions).
2. When using the water purification filter in the
humidifier for the first time or when the unit
has sat dry for any length of time, pre-soak
the Water Purification Filter thoroughly by
immersing filter in water for 5 mintues. Then
replace in the water tray and wait 15 minutes
before turning on the unit for the first time.
The 15 minute wait is necessary to ensure
that the filter is properly saturated and the
water is at its optimal level for best
performance. Then, carefully lift the water
tank and check if the water tray (I) is 2/3 full
of water. If not, replace the water tank and
wait a further 5 minutes until the water
reaches the desired level.
DO NOT switch on the humidifier until the
water tray is 2/3 full of water.
3. Turn the power dial to the I position. It is
normal for the humidifier to take about 3-5
minutes to warm up and begin to mist.
4. The Medicine Cup (B) is located on the top of
the Mist Chamber (A). To use, pour designated
humidifier medication into the groove.
DO NOT add medication to the water tank.
DO NOT add medication to the medicine cup
when the unit is already operating.
1. To activate nightlight(
), move the dial to
the on (I) position.
2. To maximize bulb life, turn the nightlight
) off (O) during the day.
NOTE: When the water tank is empty and the
water in the Heating Chamber is almost empty,
the re-fill light (red) will illuminate and the
Automatic Shut-off will activate. The unit will not
operate again until you refill the water tank and
reset the humidifier.
1. Turn the power dial to the O - off position.
2. Unplug the unit.
3. Remove and refill the water tank. Replace
the tank onto the base.
4. Wait 15 minutes for the Automatic Shut-Off
to reset.
5. After 15 minutes, plug in the unit and turn
the Mode Knob to High. The refill light should
now be off (if not repeat steps 1 through 4).
In about 3-5 minutes, the humidifier will
begin to produce moisture.
6. If the refill light remains lit, unplug the
humidifier and wait a further 15 minutes.
If you do not plan to use the humidifier for two or
more days, make sure any residual water is
drained from the water tank and base to prevent
algae or bacteria growth.
Replacing the Water Purification Filter
The water purification filter is used to retain
minerals in your water and provide a clean
moisture output. The filter life is determined by
the average daily use of your humidifier and the
water hardness in your area. Areas with hard
water will require more frequent replacement of
the filter. It is strongly recommended that the
filter be replaced at least every 2-3 months
(depending on use) or when the heating
element is starting to gather minerals on it.
To Replace the Filter:
1. Switch the humidifier to 0 - off and unplug.
Remove the tank, drain any water from the
base, lift out the used filter, and throw it away.
2. Remove the protective bag from the new
filter and pre-soak the Water Purification
Filter thoroughly by immersing filter in water
for 5 minutes. Then replace in the water tray
and wait 15 minutes for water to pass
through the filter before turning on the unit.
Cleaning and Maintenance Instruction
The following maintenance procedures must be
routinely followed in order to ensure proper,
efficient operation of your humidifier. The unit
WILL FAIL if it is not cleaned properly.
Regular cleaning prevents scale build-up on the
heating element and tray. It also prevents microorganisms from growing on the tray and tank. This
ensures that maximum efficiency will be achieved.
We cannot over-emphasize how essential
proper cleaning is to the maintenance and
continued use of your unit and the avoidance of
algae or bacteria build-up.
Regular Maintenance
The frequency of maintenance will depend on
the average daily use of your humidifier and the
water hardness of your area. It is recommended
that this procedure is carried out weekly or more
regularly if necessary.
1. Before cleaning, set the control to 0 - off
position and unplug the unit from the
electrical outlet.
2. Remove the water tank then unlock the
misting chamber by rotating the safety lock.
Lift mist chamber from the unit's base. Now
lift the tray from the base.
3. Empty water and minerals from the tray and
wash it through to remove any sediment and
dirt that has accumulated in the tray.
NOTE: It is imperative that the tray is cleaned
properly. The tray is dishwasher safe for easy
cleaning (Top rack of the dishwasher only).
4. Rinse out the tank out and refill with clean
cool water.
5. Wipe the heating element clean with a soft
cloth after it has had a chance to cool.
WARNING: If the misting chamber is left
assembled to the humidifier, it may take up to an
hour before the heating element is sufficiently
cool to be touched.
This humidifier heats the water producing a
clean moisture. Some of the impurities from the
water are collected in the Heating Chamber. The
Electronic Thermal Control Heating element is
lined with a Teflon coating that is designed to
provide the easiest cleaning to prolong the
operating efficiency of the humidifier.
DO NOT use any metal or hard objects to clean
the Heating Element. The coating can be
scratched if cleaned improperly.
Never use detergents, gasoline, kerosene, glass
cleaner, furniture polish, paint thinner or other
household solvents to clean any part of the
De-scaling Maintenance
• Scale needs to be removed as it becomes
noticeable. We recommend using Bionaire®
Clean Away - Humidifier cleaning solution.
• Apply Solution with a plastic brush to scale
surfaces. Let it soak until residue is softened.
For cleaning the tank, mix 2 capsules of
solution with 2 litres of water. Let mixture
stand for several minutes, swishing every few
minutes. Drain solution and THOROUGHLY
RINSE the tank.
