NOTE:
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
recommended to move the main switch on the control panel to the 0 position.
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 this is disconnected from the system.
5.4. Operation of the inverter on the control panel
On BEAM Commercial central vacuum units, the inverter controls operation of the suction turbine.
A transducer that measures operating suction pressure is connected to the inverter. Using the signals
received, the inverter maintains the pre-set operating parameters constant, increasing or reducing the
rotation frequency of the turbine as the conditions of use vary or according to the number of suction
hoses connected.
For BC238M and BC238A vacuum unit models, the operating suction pressure can be pre-set from a
maximum of 250 mBar H
2
O to a minimum of 130 mBar H
2
O as follows:
Double-click to move to the REF menu.
Use the central button to enter the REF menu.
Scroll through the numerical values with the left or right buttons.
Increase or decrease the values with the up/down buttons.
Confirm the value set with the central button.
Press the up button twice to return to the main display.
All operating parameters are optimized by the manufacturer, and the suction pressure is pre-set to
-160 mBar H
