5.1 Preparation Before Use
1. Place the device on a flat surface near the work area. The front of the unit should be visible during the
sealing procedure. Ensure that the power cord can be easily disconnected from the mains supply.
2. Connect the power cord according to Section 3.1, “Installation Procedure.”
3. Check that the LED indicator lights up green when the power switch is turned on.
5.2 How to Seal Tubes
Note! The tube must be dry on the outside.
1. Put the tube to be sealed in the slot of the front cover.
2. The tube activates the sealing process. The sealing electrodes press the tube together and the sealing indicator lights
up. The sealing time is normally 0.5 to 3 seconds. Avoid stretching the tube during the sealing process.
Note! Keep the tube in position until the light goes out.
3. When the light goes out, the sealing is finished, and the electrodes move back to release the tube.
4. Lift up the sealed tube and verify that it matches the pattern shown in the photo below.
5. The center of the sealed pattern is very thin, and pulling both sides will divide the tube into two pieces.
When sealing EVA tubing, use clean scissors to separate the tubing at the center of the seal.
Caution! Do not make two or more seals within 1 cm (0.39 in) of each other, because the resulting pressure in the
tube may cause microscopic cracks and holes in the seals.
Caution! In the event of device malfunction (intermittent operation, poor seal quality, or the sealing time seems too
long or too short), contact your local Terumo BCT representative for assistance.
Caution! Periodically perform a visual check of the sealing pattern to ensure it matches the photo below.

6. Cleaning
This section gives information on the cleaning procedure and frequency for T-SEAL III, which requires minimal
maintenance for efficient operation. Follow the cleaning procedure below.
Warning! For your own safety, always turn off the power switch and disconnect the power cord.
Warning! Blood and blood products must always be treated as potentially infectious. In the event of blood leaks,
appropriate protective clothing should be worn during cleanup procedures.
After removing residual biological material, surfaces that have been in contact with blood or components must be
disinfected using a sterilizing agent, such as isopropanol 70%. Alternatively, a freshly prepared solution of diluted
sodium hypochlorite (household bleach) may be used to disinfect surfaces. Diluted solutions of 1 part bleach to 10 parts
water may be used.
