Use and operation
Installation:
☞ Max. ambient temperature: 40 °C
➨ Remove the protective foils from the fittings at the flask head and the protective
covers from the inlet of the diaphragm pump or the solenoid operated valve.
➨ Assemble the connecting tube with filter between the bottle head and the inlet of the
diaphragm pump (BVC 21) or the inlet of the solenoid operated valve (BVC 01).
➨ Connect the aspiration tube of the VacuuHandControl VHC to the coupling at the
bottle head.
➨ Connect the female connector of the mains cable to the pressure control device.
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated. Keep a distance of min. 20 cm between fans and ambient
parts.
☞ If pump is installed in altitudes of more than 1000 m above mean sea level check
compatibility with applicable safety requirements, e. g. IEC 60034 (motor may
overheat due to insufficient cooling).
☞ Before switching on the pump check that mains voltage and current conform
with the equipment!
Pump with dual-voltage motor:
☞ Check that the voltage changeover switch underside the terminal box is posi-
tioned correctly.
Attention: If the pump is switched on with the voltage not correctly selected,
the motor may be damaged! Pay attention to the warning label on the on/off
switch and remove after having set the voltage changeover switch to the correct
position!
Selecting the supply voltage:
Attention:
Before starting the pump, check that
the voltage selection switch under-
side the terminal box is correctly
positioned.
Change the selection at the voltage
changeover switch only if the pump
is separated from mains.
Voltage selection switch:
Use a screw driver to adjust the supply
voltage on the voltage changeover
switch at the terminal box of the pump:
”115” corresponds to 100-120V and
”230” corresponds to 200-230V.
During operation :
The pump achieves its pumping speed, ultimate total vacuum and vapour pumping
rate only at operating temperature (after approx. 15 minutes).
☞ Prevent internal condensation, transfer of liquids or dust. The diaphragm and valves
will be damaged, if liquids are transfered through the pump in significant amounts.
