Changing Supply Tanks
This procedure outlines how to switch supply tanks
so the 75700 will exchange the correct type of
coolant for the vehicle being serviced.
1. Disconnect the supply hose from the dip tube
cap. See Figure 12. Remove the dip tube cap.
2. Connect the siphon tube to the black hose (new
coolant).
3. Insert the other end of the siphon tube into the
supply tank.
4. Turn the valves on the 75700 to EXCHANGE
until coolant stops flowing in the siphon tube.
5. Turn the valves on the 75700 OFF.
6. Connect the dip tube cap to a supply tank
containing the type of coolant that is correct for
the vehicle being serviced.
7. Connect the supply hose to the dip tube cap.
Emptying the Waste Tank
Running the 75700 unit with a full waste tank will
degrade the performance of the unit.
1. Connect the siphon tube to the black hose (new
coolant).
2. Insert the other end of the siphon tube into a
waste barrel.
3. Turn both valves on the 75700 to EMPTY
WASTE.
4. Watch the sight glass for the waste tank. See
Figure 13. Empty the tank completely.
IMPORTANT: Do not leave any waste
coolant in the black hose because it
functions as the new coolant hose when
servicing a vehicle.
