The vacuum/pressure relief valve is provided in series within this model and is calibrated by the
manufacturer. This valve is necessary to ensure efficiency in all time consuming and continuing
working conditions as the vacuum may work for long time with clogged filters and obstructed hose.
Reaching the suction pressure value, the valve opens allowing air inflow inside the turbine and therefore
ensuring cooling.
DO NOT MANUMIT the vacuum/pressure relief valve.
The Manufacturer will accept no responsibility on the machine's efficiency in case of
manumission of the vacuum/pressure relief valve and, as a consequence, the warranty will
be void.
The valve is protected by an anti-static filter which must be cleaned every six months.
