Theory of Operation
Detailed descriptions of the various operations, valves and indicators that make up the
FLUIDVAC 1000’s control panel are listed below.
3- Control valves:
♦ When the valves are in the VACUUM position .
(And unit connected to a vehicle) The unit will apply vacuum thru the “Green” hose when the air
control valve is turned on.
♦ When the valves are in the HOLD position:
After maximum vacuum has been achieved (24 inch’s of vacuum) you can turn the #3 valve to the
‘HOLD” position. This allows for system leak tests after repairs have been completed on a
vehicle.
♦ When the valves are in the FILL-CLEAN position:
The unit will pump New fluid from the clean fluid tank out of the “Green” hose.
♦ When the valves are in the FILL-USED position:
The unit will pump used fluid from the used/waste fluid tank out of the ”Green” hose.
