TROUBLESHOOTING PROCEDURES PROCEDURE 1

Blocked Fluid Passage In Diaphagm Pump

If the pump sounds like it is working but liquid does not flow, 
clear the fluid passage as follows: 

• 

Remove suction tube from the pail and blow air at 85 PSI 
into the INLET Liquid Hose (see diagram). Step on foot 
pedal to activate pump. This procedure may have to be 
repeated several times. If this procedure does not help, 
blow some water into the suction hose using a spray gun, 
wait one minute and step on foot pedal to activate pump. 
This procedure may have to be repeated several times. If 
this procedure does not work, the pump must be replaced. 

         

If you need to replace the pump call the Uni-ram Service        

         Engineer. 

The warranty on the diaphragm pump is two  

 

         years from date of purchase.

This procedure will also clear a blockage in the fluid line for the brush. Follow the same procedure to 
clear a blockage in the automatic nozzle except turn the timer instead of stepping on the foot pedal.  

PROCEDURE 2
Blocked Air Passage In Diaphragm Pump

If there is a steady hissing sound and the pump is not 
cycling, the spool valve has stalled due to a blocked air pas-
sage. Follow the procedure below to clear the blockage.

• 

Connect a blow gun to an 85 PSI source. Locate the 
blue hose that extends from the air exhaust port of 
the diaphragm pump. Use a blow gun to blow air into 
the open end of this hose. Turn timer. If the procedure 
is successful, the pump will start working. The proce-
dure may have to be repeated several times. If this 
procedure does not work, replace the pump.

• 

Cause:

 Contaminants in the air supply (water, oil, 

solid particles etc)

• 

Preventative Action:

 If necessary, install an Airline (Moisture) Filter.

PROCEDURE 3
Blocked Passage in Air Line

The components in the air line are the 

diaphragm pump, air valve, foot pedal, 3-way ball valve 

and regulator. See the Flow Diagram and the section: Replacement Parts. 

To troubleshoot a component:
1) Disconnect the air line to the component using the quick disconnect. 
2) Step on foot pedal and check for presence of positive air pressure in the air line. If there is ample 
positive air pressure, replace the component.

If air pressure is absent, there is a faulty component upstream. Reconnect the air line and check the 
operation of the next component upstream by following steps 1 and 2 above.
