TE-BBR Instruction and Operation Manual
If the shaft movement is still inhibited, check for water in the air lines:
1. Turn off air to the instrument.
2. Remove the air line from the air bearing.
3. Apply air pressure to the open line.
If water is expelled from the line, supply dry gas (such as nitrogen) to the bearing to remove
moisture from the bearing and from the line. Then, attach a trap to the air line to remove water.
Reconnect the air line and turn on air to the instrument.
Recheck shaft movement. If it is not improved, check the Load Cell wires to confirm they are not
contacting the frame:
1. Loosen the four screws at the corners of the front panel of the Load Frame.
2. Remove the front panel from the Load Frame. Make sure that the load cell wires are not
contacting the stationary part of the frame. Reassemble the front panel.
If the load cell wires are not contacting the stationary part of the frame and the problem continues,
contact CANNON
for assistance.
Flush and Drain the Air/Water Heat Exchanger
The water/antifreeze mixture should be replaced annually for reliable performance and to prevent
corrosion of internal components. To flush fluid from the Exchanger and BBR, obtain replacement
antifreeze, a funnel, a drain bucket and a supply of warm water. Then follow the procedures
outlined below.
Flush Procedure
1. Turn off the TE-BBR power switch to remove power from the instrument and Exchanger.
2. Detach the quick-connect fitting securing the tubing from the BBR to the IN connection on the
Exchanger by pushing down on the release button while pulling the hose connection out. Refer
to Figure 14. Place the tube end in the drain bucket and pull the hose off of the ribbed section of
the fitting. Fluid will begin draining from the BBR and Exchanger.
