 Do not place this device in direct sunlight or near objects that generate high temperature
heat. The heat may cause deformation or warping of the outer casing.
 Do not use the humidifier in a room that already has humidity levels above 50% relative
humidity. Excessive humidity in the room gives rise to condensation on cold surfaces such
as walls or windows.
 Do not operate the unit without water in the basin.
 Do not insert foreign objects into the device. Do not touch the transducer or the lower
water basin when the unit is operating. Do not scratch the transducer. Do not touch the
mist output when producing warm mist.

The Clean Air Optima CA-604 is equipped with a Permanent Reusable White Dust & Anti-
Microbial Filter. It consists of an inner cylinder, an outer cover and a number of small plastic and
ceramic balls. The plastic balls are embedded with nano-silver, an anti-microbial agent designed to
purify the water and destroy microbes such as bacteria and mould. The ceramic balls function to
soften the water by adhering to minerals that cause white dust. They also serve to remove any
unpleasant odour from the water. The filter requires cleaning about once a month or 1,000 hours of
use. See the Maintenance section of more information.
OPERATING INSTRUCTIONS

Operating Instructions
Before getting started, please remove the Clean Air Optima CA-604 from its box and allow it to
become accustomed to the room temperature for at least 30 minutes especially if the machine is
cold from the outside air. The CA-604 is designed to operate at temperatures between 5 -40 ºC
and relative humidity of less than 80%.
To get started, grasp the water tank by the handle at the top and lift from the base. Next, flip the
tank over and unscrew and remove the water tank lid and filter.
Then place the water tank under the faucet for filling, grasping it from the handle under the water
tank. Fill the tank with tap water (or other clean water source with water temperature under 40ºC),
re-insert the lid and filter. Flip the water tank once again until it is on the right side up. Ensure that
the basin is clean and then carefully place the water tank back on the lower body.
Wait a few seconds until the water tank lid starts to release water into the basin. You will hear a
bubbling sound as the air enters the water tank. Plug the power cord into the electrical outlet
(NEVER SWITCH ON THE HUMIDIFIER WITHOUT WATER IN THE BASIN). If the humidifier is
switched off, the power icon (#13) should now be red and the values for temperature and humidity
will now be displayed.

Press the Power Button to activate the humidifier. The machine is now operating in manual mode.
It will release cool mist on a constant basis with the mist intensity level automatically set to
medium. The two jets at the top of the machine can be rotated to blow mist in two directions. You
may also lift the jets from the water tank, adjust the positions and reinsert them back into the top
of the water tank. The output jets should not be set to spray directly onto people, electrical devices
or any obstructions. It is best to direct the jets into the open air.
The Min/Max Button changes the mist level (low, medium, high). This change is displayed on the
LCD screen by the bars (#20) that grow in size from left to right. If the machine is in automatic
mode, it will automatically adjust the mist intensity.
Pressing the Humidity Button activates automatic mode (when the LCD display starts to blink the
word “SETUP”). You can select the desired humidity level by pressing this button repeatedly until
the required humidity level is displayed (from 45% to 90% in increments of 5%). Once you select
your desired humidity level, simply stop pressing the button and your humidity level will be set.
Wait another 5 seconds and the numeric value on the LCD display will switch to the current
humidity level as measured by the built-in Hygrostat. When the humidity level in the room reaches
the set humidity level, the machine will go into automatic sleep state and stop producing mist.
When the room’s actual humidity level drops below your set humidity level about 1-5%, then the
machine will start producing mist again.
You can deactivate automatic mode very easily by pressing the humidity button until you reach
90% RH. Press the button one more time and you will now be in manual mode. You will know that
you are in manual mode because the blinking SETUP icon disappears.
Pressing the Ion Button will activate the negative ion generator and start sending healthy
negative ions into the air. It will be represented by the tree icon (19) displayed on the LCD screen.
The Heating Button activates the warm mist feature and is shown on the LCD display with three
wavy vertical lines (icon # 14). The water is heated in the basin just prior to misting. Please do not
place your hand over the jets when the warm mist function is activated. The warm mist may raise
the temperature of the room and may affect the values shown on the display.
The Timer Button sets the timer. The timer function determines how many hours the humidifier
will operate. You can set the timer simply by pressing it once for each hour that you would like to
run the unit. Many people set the timer for 8-9 hours (during their sleep) but it can be set from 1
hour to 12 hours. When the timer is set, the length of time is displayed in the upper right hand
corner of the LCD display (#16). As time passes, the time value decreases until it goes to 00:00
and the machine shuts off.
If the humidifier should run out of water, you will hear a beeping sound before the machine will
automatically shut off. The LCD screen will display the Empty Water Tank icon (#15).
The bright LCD display is designed to automatically dim after 30 seconds of pressing any of the
LCD panel buttons. The power light is also dimmed because the water tank is tinted. The result is a
soft blue glow. The light levels are bright enough to indicate that the machine is operating, yet low
enough to ensure a restful sleep in near darkness.

The following is not considered faulty operation:
 If your water is very hard (containing abnormally high levels of minerals) the humidifier
may produce white dust. This is not a malfunction. The solution would be to clean the
filter more often or use softer water.
 If you stand very close to the humidifier, you will hear the gurgling sound of water. This
is normal.
 The machine operates very quietly but it is not completely silent. Noise levels less than
25 db is considered normal.

TROUBLESHOOTIN
Cleaning and Maintenance
You can ensure many years of trouble free operation of your Clean Air Optima CA-604 humidifier
by following a few simple maintenance procedures. If your water is hard, containing high
concentrations of calcium and other minerals, then over a period of time white dust will start to
deposit on the various surfaces in the room. A white, film-like substance will also start to develop
in the water basin, on the transducer and on the inner surface of the water tank. This white film
will impede the proper function of the transducer and the operation of the machine.
We recommend the following
1. If your water is very hard, we recommend that you boil it first, allow it to cool completely
before use in the humidifier. The boiling will reduce the mineral concentration in the water.
The other option is to use distilled water if your mineral level is still too high.
2. If you are using the machine on a daily basis, clean the transducer, water tank and basin
once a week.
3. When the water tank needs a refill, empty the remaining water from the tank and fill it with
fresh water.
4. Clean the whole machine and make sure to keep all the parts completely dry when the
machine is not in use.
How to clean the transducer
1. Place 5-10 drops of vinegar on the surface of the transducer and wait for 2-5 minutes.
2. Using a small brush, cotton swab or tooth brush, gently clean the mineral film from the
surface of the transducer.
3. Rinse the transducer with clean water.
4. Never use sharp or solid objects for cleaning the transduce
How to clean the water basin
1. Clean the water basin with a soft damp cloth. If there is excess film on the surfaces, then
soak the cloth with vinegar and repeat the process.
2. If there is a film in any of the depressions along the basin, drop a bit of vinegar into
depression and clean it out with a brush.
3. Rinse the basin with clean water.
Do not use additives
Water additives (e.g. essential oils, fragrances, water conditioners etc.) must NOT be used! Even a small
amount can cause damage to the tank material. The material is not suitable for the use of such additives. One
drop is enough to damage the tank and render the appliance unusable. Appliances that are damaged by such
additives will not be covered by the manufacturer’s warranty.

How to clean the White Dust & Anti-Microbial Filter
1. Remove the filter from the water tank.
2. Put some white vinegar into a glass. Soak the filter in the vinegar for about 10 minutes.
3. Remove the filter from the glass and shake it several times.
4. Clean and rinse the filter once again with fresh water.
If you don’t plan to use the humidifier for a long time, remove the filter from the water tank and let
it dry thoroughly. Then wrap it in protective packaging and keep it next to the humidifier in a cool,
dry and dark storage space.
How to change batteries in the remote control
1. Flip the remote on its side.
2. Press the battery release on the bottom edge of the remote.
3. Grasp the battery socket and pull the battery out.
4. Replace battery with Lithium battery CR2025.
Why humidify the Air?
When the air is dry, especially in the winter months, it can become unpleasant and even unhealthy,
leading to increased levels of static electricity, dry skin, cracked lips and even noise bleeds.
Optimal humidity is between 45 to 55% relative humidity. During the winter months though,
relative humidity in the average home can drop to below 20%. Low humidity can lead to a variety
of conditions that cause ill health. Dust particles, bacteria, viruses, dust mite feces that are
normally trapped by the moist nasal membrane lining in the nose can more easily get into the
lungs when the air is dryer and thus reduce the body’s natural defence mechanism. These invaders
overload the immune system and irritate the mucous membranes resulting in more coughing and
susceptibility to disease. The Clean Air Optima CA-604 is an ideal ultrasonic humidifier for
homes, apartments, offices and anywhere where is low humidity. Ultrasonic water vapour is highly
beneficial to individuals. Their biggest advantage is high performance combined with low energy
consumption.
