Setup
Attach Hoses
1. Attach the black hose (new coolant) to the top
coupler on the upper left side of the unit’s rear
panel. The decal next to the coupler is marked
“Coolant Outlet to Car.” See Figure 1.
2. Attach the clear hose (waste coolant) to the
bottom coupler marked “Coolant Inlet from Car.”
3. Verify Valve 1 and Valve 2 on the 75700 unit are
in the OFF position.
4. Connect an air coupler fitting (user-supplied) to
the air supply inlet. Attach a shop air line to the
fitting that is regulated to supply 80–120 psi of
clean compressed air.
Assemble Supply Tanks
The 75700 is shipped with two empty supply tanks,
which will be filled with new coolant and strapped
to the back of the unit.
1. Fill one supply tank with new coolant. Install the
dip tube cap on the tank. See Figure 2.
Note: You may fill the second supply tank with a
different type of coolant, or you may leave it
empty at this time. Install the solid cap on the
second tank.
2. Place both tanks side-by-side on the back of the
unit, and secure them with the Velcro
®
strap.
4. Attach the supply hose coupler to the dip tube
cap as shown in Figure 1.
