   
At the end of an application, the running pump unit should be always
switched OFF by means of the mains switch, not with the foot switch.
This means, before switching OFF the device by means of the mains switch,
the orange LED should not be lit; also see following remark.
Remark: if the pump unit is switched OFF by means of the foot switch at the end of an application,
the next use of the device will be not possible without a foot switch.
The pump unit would not run after being switched ON with the mains switch
and would first require switching ON with the foot switch.

4.6 Functional check

Check hydrophobic bacterial filter
With the device running and open vacuum connector on the hydrophobic bacterial filter, the vacuum meter
should not indicate more than -20kPa (-150mmHg), otherwise replace the hydrophobic bacterial filter.
Check leakage
With the device running, clamp the patient tubing.
Set the vacuum control knob to maximum vacuum.
When maximum vacuum is indicated on the vacuum meter, switch OFF the device with the mains switch.
If no noticeable drop in vacuum is visible on the vacuum meter, the system is tight.
If the system is not tight, check the vacuum connections from the patient tubing to the device,
one after the other – any missing, defective or cracked O-rings must be replaced.
Also check that the seal for lid of suction jar and the lid of suction jar is correctly assembled
on the suction jar – a defective or cracked seal must be replaced.
If the maximum vacuum and the tightness can not be reached,
the device must not be operated and Technical Service must be informed.
Check suction jar and lid
Before each use, check the suction jar and the lid of suction jar
for cracks and brittle or faulty spots.
The mechanical overflow safety device on the lid of suction jar
must be assembled correctly and the float must be dry and free to move.
Damaged suction jars and lids must not be used,
not even for the vacuum check described below!
Before each use, evacuate the suction jar several times up to the maximum vacuum.
Damaged suction jars may implode under vacuum!
