In vacuum cleaners of the THOMAS TWIN range, the unique THOMAS AQUA filter system with Wet-Jet dust suppression technology is used.

 

The essence of the work of such a system is as follows:
when the vacuum cleaner is operating, water in the form of a water dust is injected into the air-dust stream,
It bursts from the suction hose into the garbage collector. Dust, grains of sand and
other garbage, rushing in the air stream, mixing with water dust,
wet, hard and in the form of dirt fall into the container to collect dirty water.

The AQUA filter system consists of three components:

  • clean water (1 liter) at room temperature, poured
    before working in a container for collection of dirty water
  • actual parts of the AQUA filter assembly with a porous filter
  • Suction filter – cube, AQUA sprayer.

Preparing for cleaning – checking the correctness of the assembly of the AQUA filter system

When delivered, the THOMAS TWIN AQUAFILTER vacuum cleaner is already equipped for dry cleaning.
Open the hinged cover of the body of the device, lifting the latch latch, and make sure
in that all components of the AQUA-filter system are installed correctly :

• The AQUA sprayer must be installed in the suction hose of the hinged cover –
through which during the operation of the vacuum cleaner into the air-dust stream sucked into the collection chamber
garbage, water is injected. AQUA sprays are retained in the spout only by two
rubber ring seals, which simultaneously seal the joint.

At the same time, the AQUA Sprayer must be fully recessed so that both O-ring seals
were inside the suction nozzle. Only in this case the connection will be sealed,
which is strictly necessary for the normal operation of the AQUA filter system.

The AQUA sprays should be properly oriented so that when closing
hinged lid, two short cylindrical protrusions on the AQUA sprayer hit the holes
8-shaped seal, attached to the parts of the AQUA-filter.
The correct orientation of the AQUA sprayer is provided by the available
in the suction pipe of the plastic projections-castings and the cut-out on the very part of the AQUA sprayer,
corresponding to the middle protrusion in the branch pipe.

When installing the AQUA spray in the suction pipe, you need to force the part with your hand.
It is absolutely necessary to hold the open hinged cover of the device with the other hand.
Otherwise, damage to the hinge and even damage the cover!

• A container must be installed in the inner compartment of the instrument
To collect dirty water with a “wet” filter.

• An AQUA filter element with a porous
filter and suction filter cube. At the same time, the AQUA filter part must be installed
for both guiding ribs in a container to collect dirty water until it stops so that
The seal, available around the perimeter of the part, was adjacent to the inner walls of the container.

• The HEPA filter must be installed in the inner compartment of the instrument.

• A filter must be installed in the inner compartment of the instrument to protect the motor.

• Pour 1 liter of clean room-temperature water into the dirty water collection container
and close the hinged lid of the case.

 

Preparation for work – check the operation of the AQUA filter system.

 

Now you should check the operation of the AQUA filter system:

• After pulling the power cord to the correct length, connect the appliance to the mains.
Without connecting the suction hose, turn on the device and electronically adjust
Set the suction power to MAX.

• When looking at the instrument from above, it should be clearly visible how, in the suction nozzle section
from the apertures of the AQUA sprayer into the air stream water is injected intensively – in the form of water dust.

If intensive water injection is not observed, it is necessary to find out the reasons for the inoperability
system of the AQUA-filter. In this case, you can not use the appliance for cleaning!

 

Visual control of the AQUA filter system.

 

Connect the suction hose and, if necessary, install the telescopic suction pipe.
In the bracket on the pipe, fix the check valve so that it does not hang.
On a hose or on a pipe to put on a suitable nozzle.
When using any of the nozzles installed directly on the suction
hose, i.e. without a telescopic suction pipe, – an adapter for the nozzles should be used,
on which it is possible to fasten the check valve. Insert the adapter for the nozzles into the selected attachment,
then fasten the shut-off valve to the adapter, and all assembled – on the suction hose.
You can start “dry” cleaning of dust in the room with the help of the AQUA-filter system.
Immediately and continuously from the moment of the beginning of cleaning the room in the garbage collection chamber of the vacuum cleaner
accumulates a variety of debris. It should be understood that sooner or later it may come (and most often comes)
such a time when the AQUA-filter system will cease to function properly due to accumulation in
her too much garbage. As a consequence, there will be a need – and, perhaps,
even repeatedly – to clean the accumulated debris of the components of the AQUA-filter and replace the water.

How quickly can this happen?

This question can not be answered unequivocally. Determining is the amount of debris,
gathering on the surfaces to be cleaned from cleaning to cleaning.
On floor coverings from a laminate or linoleum, for example, it is unlikely to accumulate a large
amount of garbage to the same, this garbage is clearly visible.
On the contrary, it is absolutely impossible to see how much dust and sand accumulates in the pile
coatings. And if a furry carpet is put in front of the front door?
And if, besides, the old rug itself “loses” the pile for you?
Or, for example, in the apartment there is a domestic animal (cat, dog,
bird) and the moulting period began?

Vacuum cleaner model THOMAS TWIN TT AQUAFILTER is not equipped with any
automatic tracking / warning devices or
forced stopping work in the event of failure of the AQUA-filter system.
Monitoring of the correct operation of the AQUA-Filter system is entrusted
exclusively on the user!
For ease of control – and, mainly, for this purpose, and not for beauty – the hinged cover of the device body
is made of transparent plastic, which makes it possible to observe the behavior of the system
without having to open the lid.

External manifestations of failure in the operation of the AQUA-filter system,
and also the reasons for the appearance of this or that effect:

  • Appearing dry dust on the inside surface of the hinged cover of the device body;
  • The appearance of a large number of water droplets on the inside surface of the hinged cover of the device body.

Dry dust on the inside surface of the hinged cover of the device body
Appearing dry dust on the inside surface of the hinged cover of the device body immediately
after the start or some time after the start of work in the “dry” cleaning mode is always associated with
absence / termination of water injection through the AQUA sprayer.

-When you start cleaning
It should be noted that if you perform a check before starting work, as described in the section
“Preparation for work – checking the operation of the AQUA-filter system”, then this situation should not arise.
This effect will necessarily be observed almost immediately after the beginning of harvesting because of, for example,
incorrect installation of components of the AQUA-filter system or their strong initial pollution, lack of water.
The severe contamination of the HEPA filter can also be the cause of the inoperability of the AQUA filter system,
since in this case, the speed of the air flow (and, accordingly, the suction power) will decrease to such a value,
that the resulting rarefaction will not be sufficient to lift water and inject it through the AQUA sprayer
into the air-dust flow.
It is easy to diagnose the state of the HEPA filter. To do this, proceed as already described in the section
“Preparing for operation – checking the operation of the AQUA filter system” check, but without installed in the inner compartment
HEPA filter (only check: use a vacuum cleaner for “dry” cleaning of the room without installed
filter HEPA in no case it is impossible!). If all components of the AQUA filter system are properly installed,
in good condition and clean, and the device is functional, then in this case there must be an intense
water injection. The HEPA filter should be attempted to be cleaned or, perhaps, replaced.
THOMAS AQUA filter

– After some time after the beginning of cleaning the premises
Currently, only one reason is known, according to which the inner surface of the flap
the housing cover of the device may appear after a short time after the cleaning of the room
dry dust. Namely, the AQUA-filter system has got such a critical amount of contamination that
turned water (1 liter), filled into a container for collecting dirty water before starting work, into the pulp.
In other words, the most important component of it – water – has disappeared from the AQUA-filter system.

A large number of water droplets on the inside surface of the hinged cover of the device body.
The appearance of a large number of water droplets on the inner surface of the hinged cover of the body
immediately after the start or after a short time
“Dry” cleaning is always associated with the clogging of a porous filter and / or a plastic mesh
on the details of the AQUA filter. The purpose of these elements is to stop large-caliber “sailing” garbage.
The fact is that, together with the flow of air from the suction hose to the garbage collection section of the vacuum cleaner
garbage of different size falls. Fine rubbish, for example, dust or sand, being moistened with water,
immediately get wet and, becoming heavy, fall into a container for collecting dirty water.
On the contrary, the fur of domestic animals, feathers, down, threads and similar large specks, possessing
large surface area (“sail”) and / or poorly wetted, are fond of powerful
air flow on. Here it is on the way of this litter and there is an obstacle in the form of plastic
mesh and a porous filter.
Let us consider the case of the “normal” operation of the AQUA-filter system, when there are no
any clogging of components.
Air flow on the way from the suction hose of the hinged lid and up to the filter
to protect the motor is freely blown through a plastic mesh and a porous filter.
Water (1 liter), filled in a container for collection of dirty water before starting work,
remains in a calm state and does not splash onto the inside surface of the hinged lid
body of the device.
If the porous filter and / or plastic mesh are clogged, the airflow, meeting at its
way “barrier”, breaks under the surface of the water (1 liter), filled in a container for collection of dirty
water before starting work. The water in the container begins to “boil” (especially well seen – through
transparent cover) in the left part of the container for collection of dirty water and is sprayed onto the inner
the surface of the hinged cover of the body of the device. If we ignore this situation, then the air
the flow will tighten the water into the internal cavities of the device until it appears at the airflow outlet.

Immediately after switching on the device
If this effect is observed immediately after switching on the device, then the reason lies in the state
porous filter. Since the beginning of the operation of this filter in the AQUA-filter system, in its
pores stuck a lot of villi from the carpet, wool, hair, etc.
You should try to thoroughly clean the porous filter from this debris. Or maybe,
It is easier to purchase and install a new porous filter. By the way, when washing this filter in water,
a false impression is created that the filter is clean and suitable for further use, since
pure water flows from it . However, properly monitor the state of this filter on the lumen, for example, by
placing it on the background of a well-lit daylight window.

Some time after turning on the appliance and cleaning the room.
If the water begins to splash on the inside surface of the hinged cover of the body of the appliance
some time after the start of work, then, most likely, this is the result of plugging the plastic mesh.
Clogging can simply be the result of a large amount of
“sailing” debris falling into the inner compartment of the vacuum cleaner .
On the other hand, this may be a consequence of the termination of water injection due to its severe pollution.
After all, if there is no injection, then all the garbage, including dust, without being moistened with water and, accordingly,
remaining dry and light, the air flow will be transferred to the porous filter and quickly clog
plastic mesh. Further – already described above effect: the air stream, meeting on the way a significant
obstacle, breaks under the surface of the water; water “seethes” and splashes on the inside surface of the
hinged cover of the body of the device.
In practice, it sometimes happens, if the user does not control the operation of the AQUA filter system.
On the inside surface of the hinged cover of the body appear consistently:
first, a deposit of dry dust; then a large amount of water spray.
At the end of cleaning, the user discovers that the entire inner compartment of the vacuum cleaner is stained with dirty grease.

 

Cleaning and maintenance of the AQUA filter system

Generally speaking, it would be a good technique not to wait for the appearance of external signs of failure in operation
system of the AQUA-filter. After all, the appearance of signs indicates that there is already a more or less
intensive spraying of dirt in the inner compartment, as well as clogging and wetting of an expensive HEPA filter.
It is better to try at least a little “to get ahead” of this moment and in advance to clean the components of the system
from accumulated debris, and replace the dirty water. This will facilitate and clean the appliance after cleaning.
Every time after the cleaning of the room, it is necessary to empty and thoroughly clean, rinse and dry all
(used) components of the device (and not only the AQUA filter system). Dirt and moisture in the closed inner
compartment of the vacuum cleaner is an excellent medium for the reproduction of bacteria and fungi. As a result,
an unpleasant putrefactive odor from the compartment.

 

AQUA Sprayer

 

Recall that during the operation of the vacuum cleaner an AQUA sprayer
injects waterinto the air streamsucked into the garbage collector, which was previously filled
into a container for collecting dirty water.
Since from the moment of the beginning of harvesting, dust,
sand and other debrispracticallyinevitablyget into this water, inevitably a part of the smallest debris – silt – gets into the AQUA sprayer.
Thus, when the AQUA filter system is operating in the AQUA Sprayer, dirt gradually accumulates.
Therefore, periodically, about once a month (after 3 – 4 cleaning), this part needs to be cleaned.

 

This procedure should be carried out as follows:

  • Open the hinged cover of the appliance body by lifting the lid lock.
  • Remove the AQUA filter element complete
    with a porous filter and a suction filter cube from the dirty water collecting container .
  • Close the housing cover.
  • Directly through the suction nozzle opening in the housing cover push the AQUA Sprayer
    into the dirty water collecting container that is left in the inner compartment of the device.
    To avoid injuring your hands, it is most convenient to do this with the help of the suction hose handle.
  • Thoroughly wash the AQUA Spray in clean, warm water.
    There should be no dirt in the holes in the part.
  • Remove dirt from the suction nozzle and from the inside surface of the hinged cover of the instrument housing.
  • nstall the AQUA Spray Gun in its place, as described earlier in the section
    “Preparing for cleaning. Verification of the correct assembly of the AQUA-filter system. “

 

Cleaning the components of the AQUA filter system in the inner compartment

  • Open the hinged cover of the appliance housing by lifting the lid lock.
  • Remove the container to collect dirty water.
  • Remove the AQUA filter element complete with a porous
    filter and a suction filter cube from the dirty water collecting container .
  • Pour out dirty water from the container to collect dirty water into the sewer.
  • Remove the porous filter from the AQUA filter part.
    To do this, slightly pull up, and then toss aside the frame holding the porous filter.
  • If dirt and threads accumulate in the suction filter-cube, for the convenience of cleaning it
    Also, you can remove it, and after installing it, reinstall it again.
  • Thoroughly rinse the container for collecting dirty water, a “wet” filter,
    an AQUA filter part, a porous filter and a suction filter cube in clean warm water.
  • Wipe the water spray in the inner compartment of the appliance with a soft damp cloth.
  • Remove dirt from the inside surface of the hinged cover of the device housing.
