  • Page 15: Routine Maintenance

    Routine Maintenance It is recommended that the following procedures be carried out on a regular basis: • Circulation fluid: This should be changed once per week, or if the water becomes contaminated. • Inline water filter: The filter should be removed, and cleaned or replaced, when visibly contaminated. See the next section for details.

  • Page 16: Installing And Removing Plates

    Installing and Removing Plates To install or remove the cell plates, follow these instructions: Upper Plate The upper plate is simply pushed onto the end of the shaft, and fixed in position by screwing up the draw- rod until finger tight. To remove it, reverse the procedure. Lower Plate The lower plate is screwed into the bottom of the asphalt bath.

  • Page 17: Chapter 4: Troubleshooting

    This chapter provides answers to some common problems that can occur while using the Asphalt Submer- sion Cell. If you cannot solve the problem using one of the suggestions on the following pages, contact your TA Instruments Service Representative for assistance. Flow Problems The flow in and out of the temperature control cell is balanced by the size of the tubing and the efficiency of the pump and suction.

  • Page 18: Leaks

    Leaks If you find leaks occurring, first locate the pipe that is leaking. Turn off the fluid circulator’s main power switch before disconnecting any lines. Disconnect and reconnect the problem pipe. If problem persists, use a sharp straight tool to trim approximately 3 mm from the end of the pipe (do not use scissors, as this will pinch a hose flat).
