Use and Maintenance Manual
MONOBLOCK Vacuum Unit
5. Use and operation of the MONOBLOCK vacuum unit
5.1 First switch-on
The completed system must be started for the first time only by an
authorized technician, who will issue a Final System Test Certificate.
After the safety and correct operation of the system have been checked, it is essential to ensure that all
persons who will be involved in operation of the system are suitably trained and made aware of all the
information provided in this manual. In particular, they must be informed of the risks involved in operation
of the system and of the precautions to be taken to reduce risks during operation to a minimum.
5.2 Operation instructions
Switching on
●
Insert the plug of the central into the in-wall electric socket with the correct dimensions.
●
Place the general switch of the electrical board on ON (>Figure 3, page 13).
●
Insert the flexible operating hose into any suction point of the system to start the vacuum unit. For
circuits with IWS system push the button on the Brava Wireless handle.
●
Make sure that the control panel is in REMOTE mode, visible on the panel
Switching off
●
close all the suction points of the system and remove the flexible operating hose. The vacuum unit

the LOCAL mode is active, by pushing the STOP button. The central can also be switched off by putting the
switch on the electrical board in OFF or removing the pentapolar plug from the socket.
It is advisable to keep the power supply to the vacuum unit turned on, allowing it to be
restarted for subsequent uses. If instead the system will not be used for a long period
of time, it is advisable to move the main switch on the control panel to the 0 position.
IT IS FORBIDDEN TO REMOVE THE PROTECTION AND SAFETY DEVICES.
DO NOT USE THE CENTRAL UNIT WITHOUT THE PROTECTIONS.
5.3 Final system test
After the industrial vacuum unit has been started for the first time, the system can be checked. It must
have no leaks. To check that the system has no leaks, first inspect the suction points (with the turbine
operating) and check that they are airtight with the cover closed. Finally check the airtightness of the
vacuum pipes, using a VACUUM METER to measure the low-pressure value at one suction point on every
operation line of the system, and comparing the value obtained with the values measured on the vacuum
unit when it is disconnected from the system. As an alternative, the frequency of operation (with
