5.2 Function
WET-5000 filtering unit works in the mode of a wet filtration, within the vacuum part of the in-
stallation, i.e. at the suction side of the fan. The polluted air, while passing through the set
of guide plates immersed in the water (so called backfall), is getting mixed with the water,
creating an aerated “dust-water” mixture.
The particles that are captured in the dust separator, create sludge with the water. The slu-
dge accumulates in the hopper and collects the waste.
It is important to empty the sludge through a drainage valve. When the air passes the back-
fall, it gets additionally cleaned from the rest of water particles, in the outdropping device.
The water level is controlled by a minimum level probe and maximum level probe.
Subsequently, the water decrease (which evaporated from the system) is re-filled through
the water supply electromagnetic valve –as a water supply control element.
Fig. No. 2 –WET-5000 wet filtering unit –Function
6. Operational Use
Before the appliance is placed on the floor, prepare the foundation adapted to the weight of
the device filled up with water. It must be placed stably on the floor, as the device vibrations
(during the function) should be foreseen.
Because of large dimensions, the device is delivered in two assemblies: the lower element
is the collecting hopper along with the supporting structure; the upper part consisting of a
mixing chamber and a fan chamber.
At the beginning, put the lower part on the foundation. Important is levelling of this assembly
and screwing up its legs to the floor. The levelling is important for the correct function of the
whole filtering unit.
Before assembling of the two parts, put the sealing on the lower flange (when the sealing is
not glued up by manufacturer).
During the assembling of the upper part, handle with care, as the sealing and the flanges are
fragile and would get damaged. Having matched and assembled together the mounting holes,
crew up tightly the external flanges (using the contact washers to attach the grounding cables
of both parts). Finally, carry out the grounding of the whole device, and examine the correct-
ness of the grounding connections (between the screwed together parts), subsequently check
the grounding of the whole device itself.

5
08.11.2019 wet filtering unit WET-5000
Make connection to the water supply system, through a manual- and electromagnetic valve,
through a pipe of minimum 1” diameter. Additionally, the sludge discharge must be carried out
by a pipe of minimum 3” diameter. During the installing, pay attention that the pipes would not
charge the device. Before the start-up of the fan, the device must be filled up with water up to
the level of overflow, i.e. to the lower line of the water backfall (see Fig. No. 2).
This level shall be indicated by the maximum level probe. The minimum and maximum levels
should be adjusted in such way, that the flow resistances is in the range 1800 and 2000 Pa.
During the first filling up with water, examine if the device is correctly levelled and the water
level is even with the water backfall line.
Fig. No.3 –Connection to the water supply
Before the start-up of the fan, close tightly the cover of the container for controlling the water
level. Otherwise it is difficult to maintain the correct water level.

Fig. No.5 –Switchgear
7.1 Description of function
To start up the device, make sure if the safety disconnector is unlocked, the main disconnector
QS1 set into position ON. After the voltage is applied (through the main disconnector), the
white HL1 lamp goes on. The red lamp HL3 –means minimum level, HL4 –maximum level –
both indicate the current level of the water.
When the water level is below the minimum level, the device cannot be started. In this case
the electro-valve gets opened and the device will be filled up with water, until it reaches
the maximum level. The state of the opened electro-valve is indicated by a green lamp HL5.
During the time when the device is automatically refilled with water, it cannot be switched on.
When the water reaches the maximum level, the electro-valve closes.
Prior to starting the device, select the control mode by switch SA1:
M –manual –the system is controlled form the switchgear or from the terminals on the terminal
strip X1 or
A –automatic.
Having selected the manual mode –to start the device press the SH2 button “START”,
or –to the terminals 12-13 fasten the mono-stable pushbutton with the terminal NO and

7

subsequently, press the button.
The fan will have a soft start-up through “delta-star” mode. At the moment, when it is
switched into “star” –the white lamp SH2 (built in the button) will go on, indicating the “RUN”
state of the fan.
It is possible to observe the signalling beyond the switchgear –in this case, to the terminals
18-19 must be connected a lamp supplied with 110VAC.
To stop the device, press the button SH2 “STOP” –or, when (in the circuit) there is plugged-
in a mono-stable button with a terminal NC, this must be pressed.
The device with an adjusted time delay 10s will switch off after 10 seconds. After the device
is disconnected, the automation checks the water level and fills it automatically up, when
necessary.
Automatic mode –first plug in the terminal NO (of the external device) to the terminals 16-17.
The external device will appoint the work mode of the appliance. This terminal must be
closed, so the device can operate. When the terminals get opened –the device switches off,
after time delay 10 seconds.
In the switchgear, there is installed a digital pressure control (pressostat).
