CLOG INTHE VACUUM TUBING
A. Check fitting just inside the inlet and just inside of the power unit for debris.
B. Isolate exactly where the clog is – by running 1 styrofoam ball (each numbered) thru each inlet. Find which balls made it to the power unit.
C. Reverse vacuum with other portable vacuum or built-in vacuum (first disconnect built-in vacuum from vacuum lines.) Suck from the inlet wall inlet that is bad.
D. Using either an electricians fishing tape, or a plumbers snake try to hook and remove the blockage. (Be very careful not to force the tape or snake or you may separate loose pipes in the attic and cause even further damage. If you”re not sure about this procedure, it is best to call and schedule a service technician for the repair.)
E. Plug into wall inlet, put hand over hose end to build pressure, then suddenly release. Try this several times from various inlets.
F. Run paper towel or TORNADO CLOTH thru inlet toward the motor unit, then reverse suck with a portable vacuum to loosen the clog.
G. Run a paper towel or TORNADO CLOTH thru the unit the portable vacuum at the nonfunctioning wall inlet. (VERY IMPORTANT – NOW RUN PAPER TOWEL OR TORNADO CLOTH THRU ALL INLETS AND MAKE SURE THEY ALL ARRIVE IN POWER UNIT CANISTER OR BAG. IF THEY DON”T, REPEAT STEPS A-F. IF THESE SOLUTIONS WILL STILL NOT FREE UP THE LINE – APPROXIMATE WERE THE CLOG IS AND LOCATE IF ACCESSIBLE (ATTIC, CRAWLSPACE, CLOSET… (NOW MIGHT BE A GOOD TIME TO CALL IN THE PROFESSIONALS)
H. Cut pipe and feel suction & visually inspect.
I. Run paper towel or TORNADO CLOTH through and listen for humming or vibration – possible nail in pipe or picture hung with toggle into pipe.
J. Run small string thru from motor unit to inlet with a portable vacuum then tie a heavier string – attach large object to heavier string. (Always tie a safety line to large object to pull it back if needed.)
H. Locate exact location by creating nose with ping pong ball. Insert in lnlet and turn on unit (remove inlet to get ball in) You may need to cut through wall or ceiling to get to obstruction – AGAIN, THIS MIGHT BE A GOOD TIME TO CALL IN THE PROFESSIONALS FOR A SERVICE CALL. Cut through the pipe and remove the clog. Rejoin pipe with proper fittings and PVC cement.
L. Again, run paper towel or TORNADO CLOTH thru all inlets.
M. If only one inlet is clogged and can not be fixed, consider relocating new pipe and installing a new outlet.
