Installing the Filter Heaters
Place the sterile gas outlet filter inside the filter heater unit. (The air outlet filter is
positioned on the left side of the bag). The proportional valve is mounted on the back
side of the air outlet supporting plate.
If the gas outlet filters are equipped with a tube extension with mounted female lure
coupling, please remove the tube extension and the lure coupling, then connect the
filter outlet to the delivered tube with a 90°-bend, as showed in the figure.
After the 90°-bend and turn the tubing lightly downwards.
The vertical part of the tube after gas outlet filter should be embedded in the filter
heater as much as possible.
It is necessary to use two gas outlet filters during aeration, so that the back pressure
can be reduced through the outlet filters accordingly.
Both ends of the air outlet tubes are connected with one Y-piece. Connect the outlet
of the Y-piece to the inlet of the proportional valve for pressure control as showed in
the figure.
Please take care as the proportional valve can be very hot during operation.
Check the exhaust gas assembly, that there are no kinks or blockages in airflow in
the tubing.
The both parts of the filter heater are connected by magnets, which are positioned
at edge of the filter heater inside.
Place the filter heater box at the magnet surface of supporting plate.
Filter heaters are automatically switched on as soon as the gassing system of
the BIOSTAT
®
CultiBag RM 600 is switched on. The air outlet filter will be heated
up > 40°C to avoid filter blocking.
Never run a cultivation without having mounted filter heaters at air outlet filter.
