Secretion jar

The influxing mixture of air and secretion fluids into the secretion jar causes the build up of foam. It's rec-
ommended to use an antifoam agent to suppress the build up of foam. Prior use of the secretion jar fill an
anti foam agent into the clean, dry jar. Don't use disinfection solution, because most of them benefit the
build up of foam.
Make sure the secretion jars are in good condition. Check the jars routinely for cracks and rifts and be sure
the jars flange is immaculate. It's important to guarantee full air tightness of the system which is responsi-
ble for troublefree operation of the pump.

Function control of float gauge valve

The proper functioning of the overflow protection system, built in the jar lid, has to be checked periodically.
If the manometer doesn't show maximal vacuum (> – 0.9 bar (relative)), the overflow protection system
has to be disassembled, cleaned and the seals have to be replaced.
9.6

Disassembly of the Overflow Protection System

If the float gauge doesn't fall back in place by itself the cleaning procedure has to be repeated and the
sitting of the O-Ring seal has to be checked and corrected.
