BPC loading instructions
5.1 General handling guidelines
Use the following general handling guidelines to ensure that no damage
occurs during the BPC loading process.
5.1.1 BPC preparation and setup
Please familiarize yourself with the imPULSE BPC and hardware before
loading the BPC. For reference, the front of the BPC is designated as
the panel containing the outlet tubes. Confirm that the volume of the
BPC being loaded corresponds to the volume of the imPULSE S.U.M.
5.1.2 BPC handling instructions
Be cautious when using scissors or any other sharp objects to open
protective outer polybags to avoid damaging the BPC. When placing a
BPC in the imPULSE tank, do not drag the BPC over corners or sharp
objects. Do not lift the BPC by the corners or top seams. For storage,
carefully coil the tubing on top of the BPC to prevent the tubing from
being punctured with cable ties or clamps. Use cushioning between
the tubing and the BPC for storage and transport.
5.1.3 Working volume
Each imPULSE S.U.M. is designed for a specific working volume range.
The minimum working volume and rated working volume are listed in
Chapter 8—Specifications and Parts Information. For normal operation,
actual working volumes should not exceed the indicated rated working
volumes.
5.1.4 Liquid transfer
The imPULSE S.U.M. BPC is designed with thermoplastic tubing,
quick-connects, and tri-clamps for adding to and dispensing from the
BPC. For liquid-to-liquid applications, a sterile environment can be
maintained as long as a sterile filter is used for inflating/venting and all
connections are made in an aseptic manner. To maintain sterility of the
mixing system, connection of additional lines (quick-connects and tri-
clamp fittings) should be made under a laminar flow hood, with a sterile
tubing welder, or using sterile connectors.
5.1.5 Dispensing
The imPULSE S.U.M. is equipped with a drain line that allows for liquid
removal by means of peristaltic pump. The drain is located at the
bottom of the BPC, allowing for minimal hold up volumes. Connection
of the bottom drain line can be accomplished using the provided
quick-connect fitting.
