within a few minutes, then please repeat steps

algae or bacteria growth.
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 Off
( ) position and unplug the unit from the
electrical outlet.
2. Remove the water tank (A) then unlock the
misting chamber (B) by rotating the safety
lock. Lift mist chamber from the unit’s base.
3. Empty water and minerals from the base and
wash it through to remove any sediment and
dirt that has accumulated in the base.
NOTE:
It is imperative that the base is cleaned
properly. The base is dishwasher safe for easy
cleaning (Top rack of the dishwasher only).
4. Rinse out the tank out and re
fi ll 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 humidi fi er, it may
take up to an hour before the heating
element is suf fi ciently 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 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
humidifier.
De-scaling Maintenance
Scale needs to be removed as it becomes
noticeable.
1. Repeat steps 1-3 in the Maintenance
section.
2. Clean the base by partially fi lling the tray
with 200ml of undiluted white vinegar. If the
element is heavily scaled, plug the humidi
fi er
into an electrical socket and turn it ON for no
longer than 15 seconds. After this time turn
the humidi
fi er OFF and unplug it from the
electrical outlet.
Let solution stand 20 minutes, cleaning all
interior surfaces with a soft brush. Dampen
a cloth with undiluted white vinegar and wipe
out entire tray to remove scale.
3. Rinse with clean warm water to remove
scale and the white vinegar solution before
beginning to disinfect the tank.
4. Wipe the heating element clean with a soft
cloth after it has had a chance to cool.
Disinfect tank:
1. Fill tank with 1/2 teaspoon of bleach and 2
litres of water.
2. Let the solution stand for 20 minutes,
swishing every few minutes. Wet all
surfaces.
3. Empty the tank after 20 minutes, and rinse
well with water until the bleach smell is gone.
Dry with some paper towel.
4. Re fi ll the water tank with cool water;
replace the water tank. Repeat Operating
Instructions.
