page 37 of 96Important notes regarding the use of gas ballastGas ballast is a continuous purge to keep the pump’s in-terior as clean as possible and to reduce the possibility ofcondensation inside the pump.➨ Air and pumped media might react inside the pump orat the outlet of the pump and form hazardous or explo-sive mixtures, when you use air rather than inert gasfor the gas ballast. This constitutes a risk of significantdamage to equipment and/or facilities, a risk of per-sonal injury or even loss of life.+ Make sure that air/gas intake through the gas ballastvalve can never lead to hazardous, explosive or other-wise dangerous mixtures. If in doubt, use inert gas.To reduce condensation in the pump, do not pump vaporbefore the pump has reached its operating temperature.Open the gas ballast valve when pumping condensablevapors. Turn gas ballast cap to open valve.NOTICEgas ballast (open) For condensable vapors (water vapor, sol-vents, etc.):- The gas ballast valve is open if the arrow onthe gas ballast cap is pointing towards theON/OFF switch.- With gas ballast valve open, the ultimatevacuum will be reduced.- Use inert gas for gas ballast to avoid the formation ofexplosive mixtures. Attention: maximum supply pres-sure of inert gas: 17.5 psi (1.2 bar) absolute.- Close the gas ballast valve by turning the cap 180°.In case of low boiling solvents (when the formation of con-densate is unlikely), the use of gas ballast might be un-necessary.
