☞ Condensate and deposits in the pressure transducer affect the measuring result.
☞ In case of deposits, aggressive or condensable media, install a gas washing bottle
before the pressure transducer if necessary.
☞ In order to avoid malfunction it is important to position the pressure transducer in
the vacuum line so as to avoid flow of condensate towards the pressure trans-
ducer.
☞ Clean pressure transducer if necessary, see section ”Cleaning and assembling
components”.
Max. permitted pressure at the pressure transducer: 1.5 bar (ab-
solute).
☞ The display flashes at a pressure higher than 1100 mbar.
☞ Comply with max. permitted pressure.
☞ Inside a vacuum system where evaporation occurs, e. g.
rotary evaporator, the vacuum is not uniform, e. g. a cold
condenser acts as pump or the vacuum in the pipeline is
lower than in the system. Therefore carefully choose posi-
tion where to connect the gauge head.

Notes on operation
Assembling the enclosed components (PC 2008/2010/2012 VARIO):
inlet
➨ Assemble separator with centring ring and clamping ring to
the inlet of the pump.
fixing screw
➨ Connect the cable of the gauge head to the female connec-
tor at the rear side of the vacuum controller.
➨ Connect the gauge head to the vacuum system by using a
small flange connection or a hose connection.
☞ The device is adjusted together with the gauge head at the
factory. If the gauge head is replaced a readjustment is rec-
ommended.
➨ Connect cable from the frequency converter of the pump to
the controller (rear side): trip line and power supply of the
frequency converter.

➨ Assemble controller CVC 2000 II
with fixing screw at the con-
troller support.
The separator at the inlet prevents droplets and particles from
entering the pump.
☞ Lifetimes of diaphragms and valves are enhanced.
☞ Improves vacuum in case of condensation.
