Connect Air Supply
Connect tubing to the gas outlet port of the BIOSTAT RM Control Tower and connect
that to the inlet port of the measurement and safety valve, which is mounted on the
right side of the air inlet supporting plate.
Connect the pressure sensor by using the delivered cable with M12 plug.
Use a Y-piece to connect two gas inlet filters to the gas outlet from the measurement
and safety valve at the same time. This will reduce the backpressure through the gas
inlet filters to a suitable range.
Check the gas inlet for any kinks or blockages in the tubing which may inhibit
gasflow.
CultiBag RM 600L has five identical air filters mounted.
Three of them are grouped together (= air outlet filter).
Two filters are grouped together (= air inlet filters).
– Connect the air supply from the BIOSTAT
®
RM Control Tower with the air filters
using the tubes delivered.
– Leave the air outlet filters open to allow air to leave the bag.
Direct connection to a gas source or use of any other air pump may cause overpres-
sure, rupture the bag and void the warranty. The inbuilt pressure transmitter cannot
feedback to an external source to stop aeration if overpressure is reached.
When there is no gas and liquid supply into the bag, we suggest clamping the tube
between bag and gas outlet filters to avoid the filter blocking.

Inflation of the CultiBag RM 600
Please ensure the both inlet and outlet filter tubing clamps are open.
1. Switch on the main switch at front side of the rocking unit, the start menu will
appear on the LCD-screen for a few seconds which shows the program version the
system is working with. The display will then change to show the main menu.
To inflate the Cultibag RM we recommend to activate the pressure control loop and
gas flow control loop in that order.
Please refer also to the section Over Pressure Management.
2. Allow the CultiBag RM 600 to fully inflate and ensure it is secured by the bag
holder of to the left- and right side.
The CultiBag RM 600 should be inflated firmly without creases.
Ensure the air outlet filter is working by pressing down gently on the bag chamber
and observing a release of air through the outlet air filter and proportional valve.
Once the CultiBag is inflated reduce air flow to process values.
Please refer to the section Set cultivation parameters and start.
