QS5 Operating Manual
The exhaust gas from the vacuum pump is composed of oil and gases
from within the pump. The exhaust gas will be hot and should be well
ventilated.
Never operate the pump with a blocked or restricted exhaust. The
resulting back pressure may blow out the sight glass or otherwise damage the
pump.
The QS5 has been designed to operate most efficiently on high viscosity
vacuum pump oil. Other vacuum pump oil may work, but performance results
may not be as stated.
The QS5 is not designed for pumping corrosive, aggressive or explosive
gases, or for use in flammable environments. Do not use with ammonia or
lithium bromide systems.
