3. Open the lid of the Exchanger reservoir and place the funnel in the opening.
4. Turn on the BBR instrument to engage the Exchanger circulating pump. Fluid from the Exchanger
and BBR will flow into the drain bucket.
5. Immediately begin adding warm water to the Exchanger reservoir through the funnel and
continue as it is pumped out into the drain bucket until the water exiting the drain hose into the
drain bucket flows clear.
6. Stop adding water to the reservoir and immediately turn off the TE- BBR power switch.
7. Replace the connector on the Exchanger hose, and reattach the connector to the fitting on the
Exchanger as shown in Figure 14.
Caution: Do not permit the Exchanger pump to operate without fluid in the
system. This damages the pump.
Drain Fluid Procedure
After the antifreeze mixture has been flushed from the Air/Water Heat Exchanger per the preceding
procedure, drain the system as follows:
1. Make certain that the TE-BBR power is OFF. Remove the external housing from the Air/Water
Heat Exchanger by removing the six screws securing the housing to the sides of the frame (three
screws on each side of the unit) and the six screws on the top and sides of the rear panel.
2. Locate the twin stopcocks at the top and bottom of the radiator. Attach a drain hose to the
bottom stopcock and place the opposite end of the hose in a drain bucket. Refer to Figure
