During Operation; Filtration; Filter And Collection Bottle - StarLab Aspirator Mode D'emploi

3.3

During operation

› Attention: When removing the hand controller, liquid in the tube may leak! Adopt suitable measures to prevent the
release of dangerous, toxic, explosive, corrosive, noxious or polluting fluids, vapors and gases. In such cases, use an
appropriate collecting and disposal system and take protective action for personnel, equipment and environment.
› Max. ambient temperature: 40 °C
› Use the system only with the integrated hydrophobic filter to protect the vacuum supply from aspirated liquids
and aerosols, and to protect the environment/user from contamination risk.
Silencer at the outlet
Attention: Dust-laden gases, deposits and condensed solvent vapor can restrict air flow out of the silencer. The resul-
tant back pressure can lead to damage of pump bearings, diaphragms, and valves. Under those conditions, a silencer
must not be used. Check the silencer regularly and replace if necessary. In case of harmful / poisonous gases or con-
densate at the outlet, remove silencer and replace with an exhaust tube.
The hand controller allows the aspiration of excess liquids. See manual "Hand controller".
NOTICE
The aspiration system does not feature an air admittance valve. If the collection bottle is under vacuum and the vacuum
demand is reduced, the existing underpressure inside the bottle remains until the vacuum is reduced (pressure rises) by
further aspiration with the hand controller.
Attention: Removing the connection tubing from the screw cap leads to immediate venting of the collection bottle. In
systems without quick couplings, removal of the tubing at the pump inlet will also vent the system.

Filtration

Connect the suction flask to the connection of the hand controller at the bottle head.
The pump achieves its pumping speed, ultimate vacuum and vapor pumping rate only at operating temperature (after
NOTICE
approx. 15 minutes). Prevent internal condensation, transfer of liquids or dust. The diaphragm and valves will be dama-
ged if liquids are transferred through the pump in significant amounts.
In case of excess temperature the motor is shut down by a thermal cutout in the winding. Manual reset is necessary.
Switch off or unplug the pump. Identify cause of failure and eliminate. Wait approx. five minutes before restarting the
pump. After a power failure, the system will automatically start again.
3.5 Storage following use
Short-term:
NOTICE
Empty bottle.
Has the pump been exposed to condensate?
Set the hand controller to continuous aspiration and the Aspirator to maximum underpressure and allow the pump
to continue to run for a few minutes. Has the pump been exposed to media which may damage the pump materials or
form deposits? Check and clean pump head if necessary.
Long-term:
Take measures as described in short-term shutdown section. Close inlet and outlet port (e.g., with transport caps).
Store the pump in dry conditions.
