Open the front cover by releasing the retaining clip on the side of the unit by hand (do not use
tools). Fit the filter squarely into the power unit by aligning the three concave points of the filter
box to the three convex points in the cavity. Then press the filter hard and rotate slightly clockwise
to lock. To unlock the filter, press it and rotate anticlockwise.
The pre-filter and the activated carbon filter should be installed on the inner side of the upper
cover, assembled in the order and direction indicated in Figure 1, and then pressed by the frame.
Three notches on the frame are aligned with three buckles on the top cover. Press the frame and
rotate clockwise to lock. To disassemble them, press the frame and rotated anticlockwise to unlock.
3.2 Switching on
The unit can be switched on by pushing the ON/OFF button for approximately three seconds. A
voice signal will be heard and the LCD will display the air flow, filter and the battery power. Then
the unit will start on the low speed.
3.3 During use
This product has three levels of air flow. By shortly pressing the " SET" button, the flow level will
change according to "low - medium - high - low..." circulation accompanied by a voice signal. The
icon on LCD also changes synchronously. At the same time, the digit on LCD indicates the real air
flow rate. If during use the air supply drops or fails entirely, leave the work area immediately. If a
signal for low battery (2 beeps repeatedly) or a clogged filter element (single short beep repeatedly)
is given, leave the workroom immediately, and check according to chapter 6.
3.4 After use
By pressing the ON/OFF button for 3 seconds, the motor will stop gradually accompanied by a long
tweet. When the icons on LCD disappear after approximately 15 seconds, the apparatus will turn
off completely.
Cleaning and disinfecting
After each session clean the unit, using a mixture of water and a mild detergent. Subsequently,
rinse thoroughly with clean water. Do not use any solvent. During cleaning ensure that no water is
allowed to enter the apparatus. The unit must not be immersed in fluid. Dry the unit with a cloth
and/or leave it to dry in the open air.
Advice
For hygiene reasons, each operator should be equipped with their own hood or mask.
