PART I GENERAL DESCRIPTION ON AIR CLEANING
If you could see the air you breathe under a microscope, you might be in for a surprise. The air quality is much more terrible
than you may think. In fact, floating in indoor air is a "soup" of particles too small to be seen by your naked eye. But it is large
enough to cause problems. Visible dust makes up only 1% of all the particles in the air. The vast majority of particles are
microscopic.
How long the particles float in the air depends on their size. Relatively "heavy" dust particles (more than 5 microns) tend to
settle out of the air in 20 minutes or less. They form the dust that's easily wiped away on tables and other surfaces.
Middleweight particles (from 1 to 5 microns) may remain airborne for hours before falling out of the air. Lightweight particles
(less than 1 micron) can remain suspended permanently in the air. And particles sized less than 1 micron can gain the easiest
entry to your body and place the biggest burden on its defense system.
No matter the type or size of the building - single family home, office, school, store, hotel, restaurant, hospital, or other places
creating and maintaining good indoor air quality (IAQ) requires three key strategies: source control,ventilation and air
cleaning. Indoor air is an intriguing, complex environment that contains a myriad of visible and invisible contaminants. These
contaminants generally fall in one of two categories: particulates or gases, vapors and odors.
Particulates
Particulates are particles that are small enough to suspend in the air. Suspended inorganic particles, such as dust, pollen, fibers
or smoke to name a few examples, are often referred to as aerosols. Suspended organic compounds and small living
organisms, such as bacteria and viruses; mold spores and pieces of a mold colony; dust mites feces and body fragments;
cockroach body parts; and dander from cats, dogs and other mammals, are called bio-aerosols.
Particle size is measured in terms of its aerodynamic properties and is expressed as microns in diameter. Particles can range in
size from very small, which can remain in the air for a long time, up to relatively large, which quickly settle out of calm air. Table
1 lists common indoor contaminants and their particle sizes.
Inhaling particulates can cause eye, nose and throat irritation and increase the risk for respiratory infections. Health care
professionals are especially concerned about the long-term effects of inhaling fine particles (less than 2.5 microns), because
they can travel deep into the lungs where they can remain embedded for years or be absorbed into the bloodstream. Asbestos
and various substances in environmental tobacco smoke (ETS) are well-known examples and some are recognized
carcinogens. Exposure to high levels of fine particles also can play a role in developing respiratory diseases such as asthma,
bronchitis, pneumonia and emphysema. Larger particles (greater than 10 microns) do not cause as much concern, because
they get caught in the nose and throat and are cleared from the respiratory tract by coughing or swallowing.
Gases, Vapors and Odors
The types of gases or vapors most often found in indoor environments include combustion byproducts, such as carbon
monoxide, nitrogen oxides, sulfur dioxide, soot particles and polycyclic aromatic hydrocarbons (PAHs); pet, human and cooking
odors; ETS; volatile organic compounds (VOCs); microbial VOCs; and mycotoxins. Many of these substances also produce
odors, some of which are pleasant while others can be distracting and irritating. Moisture also is a vapor that must be monitored
as too much moisture can support indoor mold growth.
Volatile organic compounds are prevalent in all indoor environments, with as many as 100 to 1,000 different VOCs in the air
where people can easily inhale them. Exposure to VOCs in offices and other business establishments can cause building
occupants to feel uncomfortable, distracted or sick to the point that it interferes with their ability to do their work or reduces their
motivation to work. Reducing the level of VOCs also is very important in homes and schools, because children breathe in more
air with respect to their body mass than adults and thus have greater exposure to indoor air pollutants. Some types of mold also
emit VOCs, known as microbial VOCs or MVOCs, which are responsible for the characteristic musty, earthy odors associated
with mold. People who are sensitive to MVOCs may experience eye, nose and throat irritation.

PART I GENERAL DESCRIPTION ON AIR CLEANING
A wide variety of molds also can produce mycotoxins at various times during their lifecycles. Building occupants can experience
potentially serious health problems if they are exposed to high levels of these compounds, but this is rare in most indoor
environments.
Although becoming a lesser issue in public buildings, ETS is still found in many homes, hotels, casinos, and in some
restaurants and bars. Environmental tobacco smoke alone contains more than 4,700 airborne substances, including gases
and particles from incompletely burned tobacco, of which 243 are known carcinogens.
Regardless of whether an indoor environment is the product of new construction or renovation, providing good indoor air quality
starts during the design and construction phases and continues throughout a building's life, and, it is never too late to start
managing IAQ in older buildings. Indoor environmental experts recommend three primary strategies for good IAQ, especially
when integrated into a building's overall operation and maintenance. The following highlights each of these strategies: source
control, ventilation and air cleaning.
Source control
The US Environmental Protection Agency (USEPA), the American Lung Association (ALA) and other experts agree that source
control is the only completely effective way to remove pollutants from indoor environments. They also agree that total
eradication of indoor air contaminants often is not feasible or practical. A more realistic goal is to use building materials,
furnishings, finishes, office equipment, and cleaning products and processes that emit low levels of VOCs. Surface cleaning
also removes larger particles and kills bacteria and viruses on floors, furniture, walls, doorknobs, bedding and linens, and
bathroom fixtures. In addition, keeping the heating, ventilating and air-conditioning (HVAC) system in good working order and
air ducts and drip pans clean is important for minimizing dust and particle accumulation and indoor mold growth within the
system.
Source control also involves inspecting a building regularly inside and out for any signs of water damage, which is a good
indicator that moisture levels are high enough to support indoor mold growth. The best way to prevent indoor mold growth is to
eliminate all sources of excess moisture, from leaks in the building envelope, improper building pressurization, an inefficient or
malfunctioning HVAC system, appliances to building occupant activities.
Ventilation
Ventilation and air cleaning are invaluable for picking up where controlling sources of indoor air pollutants leaves off. The two
work hand-in-hand, as many types of air purifiers are an integral part of the HVAC system.
A well-designed and properly operating HVAC system brings in and conditions outdoor air and circulates the air through the
building. The primary benefit beyond warming, cooling and managing the humidity the air is to dilute indoor air pollutants to
minimize their impact on the indoor environment and building occupants. The HVAC system also transports indoor air
contaminants outside. In addition, the HVAC system is invaluable for maintaining appropriate building pressurization, which is
critical for preventing moisture intrusion. The downside is the HVAC system may bring in outdoor air pollutants as well as pick
up indoor pollutants, such as mold spores, allergens, dust and VOCs from one area of the building and transport them to
another.
Air cleaning
Simply stated, with respect to air cleaning the goal is to remove indoor pollutants by trapping them inside a mechanical device.
Experts emphasize that air-cleaning devices alone cannot ensure good IAQ, particularly where ventilation itself is inadequate.
As noted, air cleaning is most effective when used in conjunction with source control and ventilation (USEPA 2006). Air
cleaners / purifiers employ various types of filtration technologies, which can be used in portable units that can be moved from
room to room and can be attached to HVAC systems.

PART I GENERAL DESCRIPTION ON AIR CLEANING
When you are trying to repair the air purifiers, make sure you understand the technologies used by the air purifier and the
potential issues that may be inherent in that technology which could effect the efficiency of the air purifier and your health. Most
of air purifiers may use multiple technologies in their design.
Mechanical filtration
Capturing particles in a filter via physical mechanisms without electrostatic forces
characterizes this air cleaning method. These units are capable of capturing small
particulate matter. They utilize a filter media with very high efficiency ratings. The
Letters in the word HEPA stand for High Efficiency Particulate Arrestance. HEPA filters
are composed of a mat of randomly arranged fibres. Key metrics affecting function are
fibre density and diameter, and filter thickness. The air space between HEPA filter
fibres is much greater than 0.3 microns. A common misperception is that fibrous filters
(the most extensively used in mechanical filtration) work like a sieve, with particles
becoming trapped within the spaces between the fibers. What actually occurs is that
once the particles make contact with the fibers, they remain attached due to strong
molecular forces between the particles and fibers. As a result, the particles become a
part of the filter structure and contribute to a filter's efficiency by creating resistance of
air flowing through the filter. The filter can capture 99.97% of particles as small as 0.3
microns. The disadvantage of HEPA filters is that the need for a powerful fan leads to
increased noise and energy costs compared to less efficient filtration systems, and
replacement filters are generally quite expensive. Critical design details are important
in achieving high air cleaning performance. If an air purifier using a HEPA filter is not
properly designed, air will bypass the filter as static pressure pushes against the filter
and allow particle escape. Most air purifiers on the market include HEPA filters as a
sales and marketing tactic, but fail to achieve HEPA performance.
Electronic filtration
Electrostatic Precipitators, most commonly referred to as electronic air
purifiers, operate on electrostatic attraction to a collecting section usually
called a electronic cell. A typical two-stage electronic cell has an ionizer
section (the front portion of the cell) and a collector section (the back portion
of the cell). The ionizer wires are maintained at several thousand volts by the
high voltage power supply, which produces a corona that releases electrons
into the air stream. These electrons attach to the dust particles and give them
a net positive charge. The collector section is composed of alternate parallel
plates which are charged oppositely (positive and ground) and the charged
particulate adheres to the collecting surfaces. The air velocity between the
plates needs to be sufficiently low to allow the dust to fall and not to be re-
entrained in the air stream. The electronic cell is capable of removing
particles in the range 0.01 micron to 10 microns and can achieve efficiencies
around 95 percent. Electronic cell has a very low pressure drop and high
efficiency on very small particulate. Electronic air purifiers become less
efficient as the collecting cell becomes dirty. As the surface of the collecting
area becomes heavily coated, the charge to attract the particulate is less
effective. The electronic cell must be cleaned regularly to maintain maximum
efficiency. The advantages of electronic air purifiers are they generally have
low energy costs because of low air pressure drop, the airflow through the
units remains constant with use and the electronic cell is reusable, which
avoids long-term filter replacement costs. Electronic air purifiers also can
create ozone as a byproduct of ionization. However, these devices are not
considered to be "ozone generators" as the level of ozone created is
generally low and ozone production can be reduced by adjusting the high
voltage power supply.

PART I GENERAL DESCRIPTION ON AIR CLEANING
Ozone Molecules converted from oxygen (left) as a result
of an electrical charge, such as that provided by lightning
or UV lights .
Unlike electronic cell, the ion generators don't remove the particulate matter, they only cause them to accumulate and attach
themselves to various surfaces around the room. This means that ion generators only have a temporary effect of eliminating
particles from the air. Once the particles lose the charge, they become airborne again. Those charged particles are more easily
trapped in the human respiratory system. Ion generators can produce ozone, either as a by-product of use or intentionally.
Some air purifiers use negative ion generators, which are installed at the air outlet to fresh the purified air. Negative ion has
proven to be successful in reducing the overproduction of serotonin, and therefore successful in alleviating depression in some
cases.
Electret media filter-synthetic (Hybrid Filters)
Electret media filter is a hybrid of a mechanical filter and electrostatic filter or an ion
generator in an integrated single filter. The media filter made from synthetic fibers is
inherently negatively charged in the manufacturing process and retains a charge
which attracts airborne particles that are trapped and retained within the fibers in
the conventional methods of impingement. In some cases, ionizers are used to
increase the efficiency of the trapped media. These filters obtain a moderate
efficiency on smaller particles than the electronic cell. Electret media filters must be
changed or cleaned regularly to maintain system efficiency, as the fibers loose their
electrostatic charge as they become soiled.
Negative ion-negative ion generator
Negative ions are negatively-charged electrical particles that are magnetically
attracted to allergens and other airborne contaminates, which are positively-
charged. The newly-formed larger particles are than able to fall harmlessly to the
ground, and out of the air we breathe.
The electret media filter, also
called as hybrid filter, or synthetic
filter.
Oxygen

Ozone
molecules
Ozone-ozone generator
Ozone is a molecule with three atoms of oxygen, either directly
or as a by product of ionization and electrical precipitation. High
voltage causes the oxygen molecules in the air to create ozone
(O3). Ozone does not trap particles, but can remove odors in
the air. Manufacturers of air cleaner systems that produce ozone
may refer to the ozone as "Supercharged Oxygen", "Activated
Oxygen" or "Enhanced Oxygen" Ozone molecules are
converted from oxygen molecules. The ozone molecule (O3) is
highly reactive, so whenever it encounters a floating particulate,
one of the oxygen atoms breaks away to oxidize the pollutant.
This leaves behind O2 (pure oxygen), refreshing the air even
more. Ozone generators do not utilize filters. These machines
operate by introducing the highly reactive molecule, Ozone (O3)
into the air.
This process dissipates air borne pollutants comparably the way that bleaching agents are used to sterilize water. However,
ozone is of concern when considering spaces for human occupancy. The high concentration levels required for contaminant
control are in conflict with potential health effects as established by authorities including the National Institute of Occupational
Safety and Health (NIOSH), and the U.S. Food and Drug Administration (FDA). The problem is that there is much controversy
surrounding the use of these machines as "air cleaners". Ozone is considered a hazardous workplace chemical by O.S.H.A.
(U.S. Occupational Safety and Health Administration), and is also considered an air pollutant that requires regulation by the
E.P.A. (Environmental Protection Agency. Ozone may also be particularly harmful to people with asthma.

PART I GENERAL DESCRIPTION ON AIR CLEANING
Activated Carbon Filter
The activated carbon filter can remove gas and odor. This is the physical
process of binding gas molecules to a large surface or pores of an adsorbent
medium. Activated carbon is the most common media used for adsorption and is
produced by heating carbonaceous substances (containing carbon and derived
from organic substances such as bituminous coal, wood or coconut shell) to
form a carbonized char, then activating (oxidizing) with gases such as steam
and carbon dioxide to form pores and creating a highly porous adsorbent
material. The effectiveness of odor removing media is related to the amount and
type of gasses present in the air, the quantity, type and depth of the adsorbent
material and the velocity of the air traveling through the media.
The location of the odor adsorbing media relative to the particle filtration media
is also important. If the odor adsorbing media is placed first, then particles in the
air will cover the porous structure of the odor adsorbing media and reduce its
effectiveness at trapping odors. By placing the HEPA or electronic cell first,
particles in the air are captured before the air reaches the odor adsorbing media
and allows the porous structure of the odor adsorbing media to have maximum
effectiveness at capturing gasses. Room conditions such as air temperature and
humidity also effect the capacity of adsorbents to remove odors.

Ultraviolet (UV) Light
UV light is not visible to the human eye. It refers to the part of the wavelength spectrum below visible violet light and above x-
rays and gamma rays. All light is a form of electromagnetic radiation. The distinguishing aspect of UV light is the wavelength
which is longer than x-rays but shorter than visible light. It is named because the spectrum consists of refrangible
electromagnetic waves with frequencies higher than those that humans identify as the color violet. UV light is typically found as
part of the radiation received by the Earth from the Sun. Most humans are aware of the effects of UV through the painful
condition of sunburn. The UV spectrum has many other effects, including both beneficial and damaging changes to human
health. This technology is commonly used in a variety of healthcare and water quality applications where the control of
microorganisms is desired.
UV light possesses just the right amount of energy to break organic molecular bonds. As micro-organisms pass by the UV rays
radiated from the ultraviolet lamp, this bond breakage translates into cellular or genetic damage for microorganisms, such as
germs, viruses, bacteria, fungi (like molds), etc. This results in the destruction of the microorganisms. Many of the air purifiers
use UV lamps to kill microorganisms and activate the photo catalyst filter around it.
Ultraviolet photons harm the DNA molecules
of living organisms in different ways.

How photo catalyst works
UV lamp and photo catalyst of 300T
Photo catalyst
A photo catalyst is a chemical compound that becomes highly reactive when exposed to various wavelengths of UV light. Photo
catalytic oxidation is achieved when UV light rays is combined with a TiO2 coated filter. TiO2 refers to Titanium Oxide. This
process creates hydroxyl radicals and super-oxide ions, which are highly reactive electrons. These highly reactive electrons
aggressively combine with other elements in the air, such as bacteria and VOCs. Once they are bounded together, the chemical
reaction takes place between the super-charged ion and the pollutant, effectively "oxidizing" (or burning) the pollutant. This
breaks the pollutant down into harmless carbon dioxide and water molecules, making the air more purified.
Photo catalytic oxidation
The key to PCO is the photo catalyst. Titanium dioxide (TiO2) is a
semiconductor photo catalyst with the band gap energy of 3.2eV. When this
material is irradiated with photons of less than 385 nm, the band gap energy
is exceeded and an electron is promoted from the valence band to the
conduction band. The resultant electron-hole pair has a lifetime in the space
charge region that enables its participation in chemical reactions. The most
widely postulated reactions are shown as Fig. 1.2-10 below.
Hydroxyl radicals and super-oxide ions are highly reactive species that will
oxidize volatile organic compounds (VOCs) adsorbed on the catalyst
surface. They will also kill and decompose adsorbed bio-aerosols. The
process is referred to as heterogeneous photo catalysis or, more specifically,
photo catalytic oxidation (PCO). Several attributes of PCO make it a strong
candidate for indoor air quality (IAQ) applications. Pollutants, particularly
VOCs, are preferentially adsorbed on the surface and oxidized to (primarily)
carbon dioxide (CO2). Thus, rather than simply changing the phase and
concentrating the contaminant, the absolute toxicity of the treated air stream
is reduced, allowing the photo catalytic reactor to operate as a self-cleaning
filter relative to organic material on the catalyst surface.
Photocatalyst
UV lamp
VOC is an acronym for Volatile Organic
Compounds. VOCs are organic
chemicals that contain the carbon
element. They are carbon compounds
that easily evaporate at room
temperature and often have a sharp
smell. They can come from many
products, such as office equipment,
adhesives, carpeting, upholstery, paints,
solvents and cleaning products. Some
VOCs can cause cancer in certain
situations, especially when they are
concentrated indoors. VOCs also create
ozone, a harmful outdoor air pollutant.

The sixe stages of air cleaning
1. The Pre-filter traps large dust particles.
2. The two-stage electrostatic precipitator (Electronic cell) captures airborne particles, as small as 0.01 microns. In the ionizing
section of the electronic cell, billions of microscopic particles become electrically charged as they pass through the powerful
electric field. The collector plates immediately attract and collect these charged dust and dirt particles.
3. The activated carbon filter absorbs and reduces odors, chemicals and gases, removes tobacco smoke, the smell of food and
other odors.
4. The UV sterilization chamber kills bacteria and viral microorganisms such as influenza, TB and Legionnaire's Disease as well
as other harmful contaminants.
5. When UV light hits the photo catalytic filter; it creates e- and h+, which have an excellent effect in the decomposition of odors.

PART III IMPORTANT PARTS - PRE FILTER
The pre filter is an important part of the unit. Large particles (lint, hair) are caught by the pre filter to protect the electronic cell.
Pre filter ground clip
The pre filter is manufactured with metal frame and metal mesh. When the unit is
working some charges from the ionizer section of the electronic cell will accumulate
on the metal mesh of the pre filter. If the metal mesh pre filter does not connect with
the ground clip it will discharge itself to the air and electrical shock occurs.
Do not defeat the pre filter ground plate.

Cleaning the Pre filter regularly
To ensure optimum performance from the air purifier, the pre filter and cell must be
cleaned regularly-every one to three months. Washing frequency will vary
depending on the number of family members, pets, activities (such as cooking or
woodworking) and smoking habits. Use the wash reminder schedule on the back of
page of the uni to help establish and maintain a regular cleaning schedule .

PART III IMPORTANT PARTS - ELECTRONIC CELL
The electronic cell ( electrostatic precipitator) is one of most important parts of the unit.
The unit employs a two-stage electronic cell for particulates collection. It has a stage of
ionizer wires and a stage of collector plates. The ionizer wires are maintained at several
thousand volts, which produce a corona that releases electrons into the air stream. As
the dirty air passes through the intense high voltage electric field surrounded the ionizer
wires, all particles, even the smallest are given an electric charge. The air passes into
the collector stage where the alternate parallel plates have positive and negative
charges, creating a uniform electrostatic field. Since opposites attract, the charged
particles stick to the collector plates, having an opposite electric charge. Consequently,
the air leaving the air purifier contains very few particles. Theses electrons attach to dust
particles and give them a net negative charge.
The second stage, the collector
section of the cell is the collecting
section composed of alternate
parallel plates which are positive
plates and ground plates. When the
positively charged particles are
passing through the collecting
section they will be trapped by the
ground plates.
Particulates
The first stage, the ionizer section
of the cell is the charging section
composed of ionizing wires and
grounded plates. When the power
supply provide high voltage to
ionizing wires it create a strong
electrical field and give charges to
the particles in the air stream.
Some of the charged particles are
attracted to the ground plates.
How does electronic cell work?
The high voltage power supply provides the cell high voltage to the ionizer section and low voltage to the collector
section through the two power contact terminals. If the power supply is broken the cell cannot work, failing to collect
the particulates in the air.

PART III IMPORTANT PARTS - ELECTRONIC CELL
1. DO NOT clean the cell with alcohol, gasoline, paint thinner
or other flammable substances. It may cause fire!
2. DO NOT reinstall the cell until it is completely dry. If the
CHECK light on the control panel flashes red, then the cell
may still be wet.
3. Be sure there is no detergent residue around the cell
ceramic insulators, especially around the square shape
ceramic insulators.
4. Slide in the cell so the airflow arrow points toward the machine.

The square ceramic
insulator was burnt and
cracked down because of a
long time use of the wet cell.
Discoloration of the cell
Occasionally, after the cleaning process, the cell may seem stained. If the stain is black or very dark, it is probably
detergent residue and should be rinsed off at once. If yellowing appears, it is probably stain from tobacco or other smoke.
The yellowing does not affect air cleaning efficiency. Use ammonia based or butyl based detergent to clean tobacco tar
and other smoke residue from the collector plates.

PART III IMPORTANT PARTS - ACTIVATED CARBON FILTER
The activated carbon filter is also one of the important parts of the unit. The activated
carbon filter of the unit is located behind the electronic cell. Activated carbon, the
universal adsorbent, has a capacity for virtually all vapor contaminants and will adsorb
and retain a wide variety of chemicals at the same time.
The adsorb diffuses thru the surface film to the macropore structure. Then, due to van
der Walls' forces, the gas molecule migrates into the micropore structure, condensing
during this movement, and finally stopping when either the forces become balanced or
it becomes physically blocked.
To improve the odor removing performance, the unit utilizes a carbon powder
impregnated pad not granular form. Room conditions such as air temperature and
humidity also effect the capacity of adsorbents to remove odors.
The activated carbon filter should be replaced when it is no longer effective in
eliminating odors.
Replacing the activated carbon filter
When the CARBON FILTER ( FILTER LIFE) indicator light on the control panel flashes you need to replace the carbon filter.
After replacing the carbon filter, you have to reset the unit.
1. Remote control: Press the RESET1 5 times or press the RESET button 3 times ( when there is only one RESET button on the
remote control).
2. Press one time the reset button on the back of the unit.
3. Hold 3 seconds the POWER button to reset.

PART III IMPORTANT PARTS - UV LAMP AND PHOTO CATALYST
After removing the activated carbon filter, you will see a UV lamp behind
the UV light blocker and photo catalyst behind them. The unit utilizes 6
watt UVC lamps in the 254 nm range and photo catalyst. The UV lamp is
effective in destroying the nucleic acids in these organisms so that their
DNA is disrupted by the UV radiation.
When the photo catalyst (TiO2) captures UV light, it forms activated oxygen
from oxygen in the air. This process is similar to photosynthesis, in which
chlorophyll captures sunlight to turn water and carbon dioxide into oxygen
and glucose. The formed activated oxygen is strong enough to oxidize and
decompose organic materials or smelling gas, and kill bacteria.
The UV lamp ballast is located inside the UV lamp holder. The UV lamp
power cord is connected from the main circuit board to UV lamp ballast (UV
lamp holder).
Replacing the UV lamp
When the UV LAMP indicator light on the control panel
flashes you need to replace it. After replacing the UV lamp,
you have to reset the unit. The photo catalyst will not be
replaced. However, remove any dust by a vacuum cleaner.
1. Remote control: Press the RESET2 5 times or press the
RESET button 3 times ( when there is only one RESET
button on the remote control).
2. Hold 5 seconds the reset button on the back of the unit.
3. Hold 3 seconds the POWER button to reset.

Replace interlock switch
The interlock switch is rarely broken. If the unit has no power and you confirm that the interlock switch is problem, you will
follow the below steps to dismantle the interlock switch and do the reverse operation to replace a new one. Make sure all the
black Live line and white Neutral wire are connected correctly before starting the unit.
Interlock switch
Interlock switch
adjustor
The interlock switch is provided with a lever which can be actuated by the actuator on the front panel. The interlock switch opens
all supply conductors simultaneously when opening the front panel for servicing. When the front panel is closed the actuator
pushes down the interlock switch levers and the unit will operate. When the front panel is opened the levers will be spring out
and interrupt the Live line and Neutral wire at the same time to stop the operation. The purpose of the interlock system is to
interrupt the operation of the unit when the front panel is opened by accident, and similarly, to prevent any operation until the
front panel is firmly and safely closed.
