Description of precautions
Use of safety glasses is recommended during installation, set up, operation and while any service
or testing is being performed on the system.
You must use the Supply Air Protection Assembly (SAPA) on your air source to ensure air is
brought to a safe pressure, and suitably filtered to ensure pump functionality.
Vessels or bioreactors should not be pressurized unless otherwise specified by the manufacturer.
Glass and single-use bags can explode if pressurized. When using any vessel or bioreactor, be
sure to maintain an unrestricted vent or exhaust from the vessel. This will ensure that no
significant pressure or vacuum occurs in the bioreactor. In the case of a diaphragm failure, for
example, air will penetrate the XCell ATF® Device, through the filter and into the vessel. A free
exhaust from the vessel will minimize the build-up of pressure in the vessel.
You must replace the air filter on Stainless Steel XCell ATF® Devices (ATF2 and ATF4) prior to
operation.
When not in use, you should ensure all the tubing is capped or blocked using the provided caps
and valves. It is recommended to keep unused tubing in the original sealed bag.
