Thank you for purchasing the innovative Heaven Fresh HF 758 Digital Ultrasonic Warm and Cool Mist Humidifier. We
wish you many years of healthy indoor air with this efficient and effective product.
Ensure that all safety precautions are followed when using this electrical appliance for the proper operation of the
device. These instructions describe the safety precautions to be observed during operation. They are designed to
prevent injuries or damage to this device.
The inner ultrasonic transducer is highly sensitive. Do not touch it with bare fingers or scrape it with metal tools, or it
will reduce mist output. When cleaning this area please use a small cleaning brush, cotton swab or tooth brush. Do not
use hot water as it may damage the misting parts.
Use proper voltage - AC 110~120V 60Hz in Canada/USA; AC 220~240V 50Hz in Europe. Use of improper voltage
may cause fire hazard or electric shock.
To prevent electric shock, do not dismantle, repair or modify this product. Maintenance and cleaning should be
followed exactly as instructed in this manual. In the event of a malfunction, please contact an authorized Heaven Fresh
maintenance center.
Do not use in areas where flammable or explosive materials are stored.
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.
Do not submerge this device in water. Water or cleaning liquids may only be used on parts to be cleaned according to
the cleaning and maintenance instructions.
Only use lime scale remover or vinegar to clean mineral deposits from the basin or transducer. Do not use any harsh
detergents that may damage the unit.
If you smell an abnormal odour, please turn off and unplug the unit and call Heaven Fresh technical support.
Clean and dry the device before storage (including the removal of all water from the inside of the device).Store the
machine in a cool and dry place outside the reach of children.
Do not use fabrics or other materials to cover this device. Obstructed air inlets and outlets will result in improper
operation of this unit and may result in fire or other damage.
To prevent interference and damage to other electronic devices, this machine should be placed at least 1 meter away
from a computer, television, radio or other electronic equipment.
The ultrasonic humidifier should be cleaned regularly for proper operation and long life. See cleaning instructions.
For safety reasons and to prevent fire or electric shock, unplug the power cord from the electric outlet socket whenever
you:

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 defense mechanism. These
invaders overload the immune system and irritate the mucous membranes resulting in more coughing
and susceptibility to disease.
The HF 758 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.
