Liquid level sensor (699908 / 699909)
Safety information!
Use the level sensors 699908 and 699909 only in combination with VACUUBRAND vacuum con-
troller CVC 3000 or VNC 2 (connection only possible to VACUUBRAND VACUU•BUS system).
Remove all packing material, remove the product from its packing-box and inspect the equipment. Do
not use the equipment if it is damaged.
Use the components only for the intended use, i. e. to monitor the uid level inside a VACUUBRAND
catchpot from outside:
- Level sensor 699908 for catchpot 500 ml (cat. no.: 638497)
- Level sensor 699909 for condensate ask 1000 ml (cat. no.: 638877)
Do not immerse the level sensor into liquid.
Comply with all relevant safety requirements (regulations and guidelines) and adopt suitable safety
measures.
Comply with all applicable national safety regulations.
Pay attention to the maximal permitted ambient temperature.
Use only genuine spare parts and accessories. Otherwise safety and performance of the equipment
might be reduced. Ensure that maintenance is done only by suitable trained and supervised technicians.
As laid down in the statutory regulations (occupational, health and safety regulations and regulations for
environmental protection), equipment returned to the manufacturer can be repaired only under certain
conditions.
Use and operation
The level sensor is intended to be assembled at the bottleneck of a VACUUBRAND catchpot 500 ml
(cat. no.: 638497) or at a condensate ask 1000 ml (cat. no.: 638877) recommended at the catchpot of
an exhaust waste vapour condenser.
Important: Assemble the sensor as close as possible to the catchpot.
Assembling the level sensor at the catchpot 500 ml
➨ Assemble the level sensor to the bottleneck.
➨ Loosen the adjustment screw (1) at the sensor.
➨ Adjust the sensor as close as possible to the condensate ask.
➨ Screw adjustment screw.

Remove clip with sensor from the bottleneck.
When reassembling ensure that the sensor is posi-
tioned as close as possible to the condensate ask.

opening of the strap
closing of the strap
➨ Attach both straps on the condensate ask.
➨ Position mounting plate under the straps. Assemble the liquid level sensor in a way that the sensor
becomes activated at the desired maximum liquid level.
➨ Close straps.
➨ Loosen the adjustment screw at the sensor.
➨ Adjust the sensor as close as possible to the condensate ask.
➨ Screw adjustment screw.
