HF 707 Digital Warm & Cool Mist Ultrasonic Humidifier
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
The HF 707 is an ideal ultrasonic humidifier for homes, apartments, offices and anywhere there is low humidity.
Ultrasonic water vapour is highly beneficial to individuals. Their biggest advantage is high performance combined
with low energy consumption.
Ultrasonic Humidifiers use ultrasonic high frequency oscillation to break up water into tiny water particles about
1.5 microns in diameter. The ventilation system blows out the water particles into the dry air where they evaporate
and create the required humidity level. The water particles appear as a steady stream of mist or fog as they travel
up and out of the machine.

Before getting started, please remove the HF707 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 HF 707 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 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, 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 HF 707 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.

with clean water.
HF 707 Digital Warm & Cool Mist Ultrasonic Humidifier
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 35 db is considered normal.
If the above recommended solutions do not work, please contact Heaven Fresh technical
support at the telephone number for your region. Do not attempt to disassemble, repair
and reassemble the machine as it may void the warranty.

You can ensure many years of trouble free operation of your HF 707 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:
If you 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.
If you are using the machine on a daily basis, clean the transducer, water tank and basin once a week.
When the water tank needs a refill, empty the remaining water from the tank and fill it with fresh water.
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:
Place 5-10 drops of vinegar on the surface of the transducer and wait for 2-5 minutes.
Using a small brush, cotton swab or tooth brush, gently clean the mineral film from the surface of the
Rinse the transducer with clean water.
Never use sharp or solid objects for cleaning the transduce

How to clean the water basin:
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.
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.
Rinse the basin with clean water.
How to clean the White Dust & Anti-Microbial Filter:
Remove the filter from the water tank.
Put some white vinegar into a glass. Soak the filter in the vinegar for about 10 minutes.
Remove the filter from the glass and shake it several times.
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:
Flip the remote on its side.
Press the battery release on the bottom edge of the remote.
Grasp the battery socket and pull the battery out.
Replace battery with Lithium battery CR2025.
At the end of the product life cycle, you should not throw this machine into the normal household garbage but
