Purifier-4

Power
Press the Power Button to activate the device
Press the Power Button again, the device turns off.

MODE
Press the MODE Button to select one of four desired programs:

Smart Mode: Desired humidity set to 55% relative humidity and the fan is automatically adjusted depending on the current humidity level.
The desired humidity can not be changed in this mode.
High/ Low Mode: Select the Fan speed, the desired humidity can then be adjusted using the + and – buttons.
Fan Mode: Continuous air purification (low fan speed, no dehumidifying function).

Air purification
If the desired humidity level is reached at a constant level, you can switch to program 3 to use the device for continuous air purification.

Humidity Button

By pressing the up or down button, you can select the desired humidity level. The required humidity level is displayed (from 35% to 80% in increments of 5%). Once you select your desired humidity level, simply stop pressing the +or – button and your humidity level will be set. When the humidity level in the room reaches the set humidity level, the device will stop dehumidifying. When the room’s actual humidity level increases again above your set humidity level, then the device will start dehumidifying and air purifying again. If the relative humidity is set to 35%, the compressor will only stop when the water tank is full.

UV and ION

After pressing once, the UV function is switched on.
After pressing twice, the ION function is switched on.
After pressing three times, the UV and ION functions are switched on.
After pressing four times, the UV and ION functions are switched off.
UV sterilization technology is accepted for more than fifty years and it has been proven that it can considerably reduce the number of bacteria and polluting substances in the air safely Pressing the Negative Ion Button will activate the negative ion generator with a total capacity of > 3.000.000 negative ions / cm² that are spread through out the entire room and thereby neutralize pollutants and smells. Negative ions attach onto dust particles, microorganisms and other unwanted particles in the air and connect them to each other. This way, the particles become heavier than air and fall onto the ground so that you can no longer breathe them in.

Negative ions are most found in the forest, mountains and by the sea.
Negative ions ensures fresh and healthy air.

Timer
Press the Timer Button to set 0-24 hours timing. Use button + and – to set the time period (0-24 hours). When the device is operating, the timer that is set indicates when the device switches off. If the device is in stand-by mode, the timer that is set is to instruct the device when to turn on.
Sleep
Press the Sleep Button and the sleep mode is activated, the display will turn off (The fan is running in the lowest speed level).
Press the Sleep Button to switch back again in the settings before.
Laundry Mode
Press the Laundry Mode button and the drying mode is activated.
The humidity is set at 35% and is not adjustable. The compressor does not stop and continues to run until the water tank is full or if the function is turned off.
OSC oscillating function/ Child lock
The oscillation function ensures good air distribution in the room. Oscillating distributes the air evenly. There are two positions, fixed or moving.
Child Lock is switched on / off by pressing the Child Lock Button for ca. 3 seconds.
Child Lock protects from unwanted use of the device.

Water Tank Full Indicator Light
When the water tank is full, the device will stop automatically. The Water Tank Full Indicator Light turns on and lights up. Drain the water tank, and return the water tank to the body of the device, the Water Tank Full Indicator Light will turn off. The device will work automatically again.

Defrosting Indicator Light
The evaporator in the dehumidifier may defrost automatically if it is operated with a room temperature less than 18 °C. The defrosting device in the dehumidifier may start up and operate for some time (about 8 minutes) automatically.

During the defrosting operation, the dehumidification function and air purification function may intermit.
Don’t turn of the power or pull out the power plug of the device during the defrosting operation.

Water Drainage
The Water Tank Full Indicator Light will light up when the water tank is full. Take out the water tank and empty the water inside. Then put the water tank back into the dehumidifier correctly,see the illustration below.

Open the back cover of your device
Hold the water tank by its handIe
Pull the water tank out carefully
Empty the water tank

Maintenance

Cleaning the housing of the Clean Air Optima® dehumidifier

Switch off the device and pull the plug.
Use a soft and humid piece of cloth to clean the device. Do not use chemical solvent such as benzene, alcohol or gasoline.
Make sure that no water gets into the device, do not sprinkle with water.

Replacing of filters
The Clean Air Optima CA-704 / CA-707 is equipped with a filter lifespan surveillance mechanism that signals that the filter (HEPA + Activated Carbon Filter) have to be replaced after 500 working hours. To show that the filter need to be replaced, the dehumidifier emits a double zero indicator light. Reset the timer for the filter by pressing and holding the laundry button for about 3 seconds. If the indicator light goes out, the timer has been successfully reset.
Depending on the use, the Activated Carbon Filter and True HEPA H13 Filter has a lifespan of approx. 3 – 6 months. The Pre-filter and UV-C lamp are permanent, no replacement needed.
Take out the filters from the filter frame compartment. After filter replacement or filter cleaning reinstall the filters back into the filter frame compartment and assemble back to the device, see the illustration below.

Filter cleaning
The best effect for a longer lifespan of the Filters is reached by cleaning the filters once a month. If indoor air is extremely polluted, we advice to clean the filters more often ca. once per two weeks.

Clean the Pre-filter, Activated Carbon Filter and True HEPA H13 Filter carefully with a brush or your vacuum cleaner. That way bigger dust particles like lint, hair, dust and dander of pets can be removed from the filters.

Room temperature increases during operation
The Clean Air Optima® dehumidifier doesn’t have a cooling function. The device will produce heat during operation and increase the room temperature between 1 °C to 4 °C.

Dehumidifying capacity
The illustration below shows the dehumidifying capacity of the Clean Air Optima® dehumidifier.
By different temperatures and relative humidity, the dehumidifier may have different dehumidifying capacities.

Warning!
Do not damage the filters, the filters must not be cracked. Damaged filters needs to be replaced.
Never wet or rinse the filters (Only for Activated Carbon Filter and True HEPA H13 Filter) with water. Filters that are rinsed with water needs to be replaced.

Signs for used up filters that needs to be replaced
(Only for Activated Carbon Filter and True HEPA H13 Filter)
Increased sound, reduced air flow, congested filters, rising presence of smells. Filters needs also to be replaced by new ones when the True HEPA H13 Filter changes its color from white to grey or black. If the True HEPA H13 Filter remains white, there is NO need to replace the filters.
