Trouble Shooting 

 

1.  IF NOT RUNNING: 

 

Verify GFI cord set is plugged into an active outlet—the indicator light will be on. 

 

Make sure main electric switch is in the on position. Green electric motor should be      
operating. 

 
2.  IF NO VACUUM: 

 

Verify ½” tank drain plug is installed.  

 
 

1” suction valve should be in closed position. 

 

Vacuum gauge should indicate 10 hg vacuum. Note: vacuum reading can vary slightly 
depending on operating altitude and temperature. 
 
Check for loose nuts on tank flanges and check barrel ring bolt. 

Caution: do not over 

tighten barrel ring bolt since this can cause distortion of the ring and barrel lid.

  

 

 

3.  IF LOW OR NO VACUUM AT END OF SUCTION HOSE: 

Clean out 1” wye strainer—remove 3/8” plug and then remove large bushing and pull out 
strainer basket. Check for any blockages. 

 

4.  IF GUAGE READS 10” Hg AND THERE IS NO SUCTION ON END OF  

SUCTION HOSE: 

With 1” valve open reset anti flood device. 

 

5.  TO RESET ANTI-FLOOD DEVICE: 

Unplug unit and remove ½ drain plug from back of tank, remove all water from tank, 
lightly tap the tank and a “thud” should be heard. The anti flood is now reset. Replace ½” 
drain plug and proceed. 

 

6.  IF MOTOR IS NOT RUNNING:  

 

Motors are manual thermal overload protected. 
Allow 30-40 minutes for unit to cool.  
To reset/push rubber button until you hear a loud and distinct click 
Use proper electrical supply (120v 20amp) 

 

7.  IF NO WATER DISCHARGE: 

 

Please call manufacturer.
