PRESSURE ADJUSTMENT
7.a Operating pressure
After connecting nebuliser RF7 Plus to the device with the Selector Button (C.4) closed in the position With
Valve, operating pressure can be adjusted by rotating Knob (A3), clockwise to increase it or anti-clockwise
to decrease it, until selecting the colour sector visible on the Pressure Gauge (A6) matching the desired
particle size shown in the table below.
Throughout the device life, from time to time it is necessary to check maximum pressure attainable with
the RF7 Plus nebuliser connected and with Knob (A3) turned on MAX.
If the maximum value of the green sector in the Pressure Gauge is not reached (A6), the device must be
serviced.

CHOICE OF DELIVERY METHOD
7.b Delivery method
Nebulisation can be obtained by maintaining the valve system active, or selecting the delivery mode at
top speed, by means of the Selector Button (C5.4) of RF7 Plus atomiser. The mode must be selected after
setting the operating pressure.
8. Start the device by means of switch (A1) and breathe deeply in and out.
9. Upon completing application, turn off the device and unplug it.
10. If after the therapy session an evident deposit of moisture forms within the pipe (B), detach the pipe
from the nebuliser and dry it with the very ventilation from the compressor; this operation prevents pos-
sible blooms of mould inside the pipe.
