5.3 - OPERATING LIMITS
During use, do not exceed the conditions of speed and power established by the manual.
ATTENTION: the BLW is not suitable for conveying toxic, flammable or dangerous gases.
ATTENTION: the BLW is not suitable for working in potentially explosive environments.
For environments classified as potentially explosive, use the ATEX BLW
ATTENTION: the introduction of solids or liquids will seriously damage the BLW.
5.4 - CONTROL DEVICES
A handle (1), located at the top of the manifold, is provided for the control of intake and compression phases. This can be operated
manually. To establish in which direction the handle must be turned to select the intake or compression phase, follow the instructions
provided by the manufacturer of the system. If the reversing gear locks up, use a lever to lift the handle.
Selection of the suction or compression phase using the handle must be performed with
the blowers pump stopped.
5.5 - STOP
To stop the vacuum/pressure blowers pump it is necessary to suspend the PTO motion transmission in a manner that varies depending
on the versions in order to avoid unintentional activation. Eliminate the differential pressure from the system and bring it back to
atmospheric pressure.
