4. Regulation - unit control
4.1. General information - safety
- Regulation is integrated into the body of the unit. Any manipulation other than specified in this manual
is prohibited.
- All control elements located on the body of the unit, which are designed for user control, are powered
by 10VDC (safe voltage).
4.2. Controls
4.2.1. Main control panel
4.2.1.1. Main control - knob (position 1)
- The main control (know) allows for continuous adjustment of the power of the unit in any position from
the minimum to maximum power according to the user's requirements.
- The "OFF" position switches the entire unit off.
- The "OFF" position does not disconnect the unit from the power supply (the unit may be disconnected
from the mains using the main switch located on the back of the unit or by unplugging the power cord
from the power outlet)
4.2.1.2. Signal diode
- Indicates operation of the unit. If the LED is ON, the unit is active. If it is not lit, the unit is turned off
4.2.1.3. Indicator of filter box clogging - signalisation of need for filter box replacement
- The orange indicator activates when the filter box is clogged. At the same time, it informs the user about
the need to replace the filter box (box replacement is described in the chapter 7.1.2. filter box
replacement).
- The indicator activates automatically depending on the current, actual clogging of the filter box, which is
set by the manufacturer.
- One of the parameters that affect the activation of the indicator is also power-flow the whole unit is
operated at. In general, the smaller the power-flow of the unit, the longer the time for indicator activation
(the less air is filtered).

- Select the appropriate unit output based on area of the space to be filtered.
7. Regular maintenance and cleaning of Miracleair units
- Before any maintenance and cleaning of the unit, the unit must be disconnected from the power
supply – unplug the mains cable.
7.1. Regular maintenance – inspection
7.1.1. General information
- Perform a regular visual inspection of particulate filter clogging (top filter in the filter box). The filter also
captures inadvertently sucked components, which can significantly reduce the extraction power of the
unit.
- Always perform the regular inspection of the unit when replacing a dirty - old filter box with a new one.
Filter replacement is described in a separate chapter 7.1.2.

- If the unit does not require the replacement of filters more often than once a year, the unit must be
inspected regularly, at a maximum interval of once every 12 months or at intervals determined by the
relevant national regulations or practices.
- If the unit is not used for longer time, it is necessary to turn off the supply voltage to the unit.
- Service work beyond normal maintenance may only be performed by the manufacturer.
- Regular maintenance must include:
o Visual inspection of the unit housing, mechanical components
o Visual inspection of the arm, in particular the locking screws
o Visual inspection of the mains cable
o Check that the pressure measuring hose is correctly connected at the pressure coupling and at
the measuring points.
o Check that the pressure caps are tightened correctly – they must not be loose. If necessary, the
cap must be opened – then tighten the clip by 1 turn (360°) and then re-tighten it. Always tighten
the pressure caps one at a time.
- The unit is designed and manufactured so that it does not require any special maintenance
7.1.2. Filter box replacement
- The filter box may contain dust particles, bacteria and viruses, so it is necessary to use appropriate
protective equipment to prevent contamination or contact with harmful substances. When carrying
out any work with the filter box, we recommend to use at least disposable polypropylene gloves and a
fine dust protective mask (protection level 3).
- The need for replacement of the filter box is indicated on the main control panel by the orange indicator
for filter box clogging
- The indicator activates whenever the filter box is clogged as set by the manufacturer.

- Clogging of the filter box and subsequent activation of the indicator depends on the environment where
the unit operates. In particular on:
o Ambient air dust load - the more dust particles are in the air, the sooner the filter box becomes
clogged
o Operating power of the unit - the more air the unit filters, the sooner the filter box becomes
clogged
- After the light comes on, immediately replace the filter box with a new one, as follows:
a) Switch off the unit using the main control (knob) to the OFF position and the main switch from the
back of the unit to the position 0.
b) Disconnect the unit from the power supply by removing the plug of the mains cable from the socket
c) Remove the side covers from the side of the unit.
